8 stunning sky shots win David Malin Awards 2014

Swirling dust and star-forming gas, solar explosions and dancing dishes. These are among the eight photographs and videos that have won top honours in this year’s David Malin Awards, Australia’s premier astrophotography competition.

Renowned photographer Dr David Malin judged the awards, which are run by the Central West Astronomical Society.

“The winning entries show both technical skill and an ability to capture the beauty of the sky in a visually pleasing way,” said John Sarkissian, CSIRO Operations Scientist at Parkes radio telescope – ‘the Dish’ – and organiser of the awards.

“More than 200 entries were submitted this year. With such stiff competition, to have received any one of these awards is a great honour. Congratulations to all of the finalists and winners.”

And the winners are…

Overall winner and winner Deep Sky category: ‘Dust and Gas’, Paul Haese

The Deep Sky category is for photographs taken with a telescope. Paul Haese’s winning entry shows the Great Nebula in the constellation Orion, a star-forming region located 1,300 light years from Earth. The nebula is 24 light years across and Paul’s image shows all the dust and gas in the region.

“This is the best true-colour image of the Orion nebula I have seen for a long time,” said David Malin. “It has everything. The basics are well covered by a realistic-looking colour balance and the dynamic range, which makes the heart of the nebula look brighter than everything else, which is as it should be. But the other things are right too, including the delicate, faint nebulosity that fills the field and the careful handling of the bright stars, which don’t dominate the image. Fantastic!”

Winner Wide-Field category: ‘Dusty Heart of the Milky Way’, Phil Hart

“This is a two-frame mosaic of the bright and dusty central regions of our Milky Way Galaxy. The view is toward the centre of the Galaxy in the direction of the constellations of Sagittarius and Scorpius,” said Phil Hart. The Wide-Field category is for photographs taken without the use of a telescope.

Winner Open Theme – The Moon category: ‘Marine Moonset’, Phil Hart

This year’s open-themed section sought innovative and imaginative images of the Moon, in any of its phases and guises. Phil Hart’s winning entry captured the full Moon as it set over the shipping channel in Victoria’s Port Phillip Bay, as seen from St Kilda an hour before sunrise on 14 May 2014.

Winner Solar System – Hires category: ‘Mars 2014’, Stefan Buda

The Solar System – Hires category is for high-resolution images involving subjects that appear smaller than the diameter of the full Moon.

“Every two years and two months, the Earth and Mars approach each other. This image represents a record of the appearance of the planet Mars between January and May 2014,” said Stefan Buda of his winning entry.

Winner Solar System – Wide-Field category: ‘Prominence’, Paul Haese

The Solar System – Wide-Field category is for wide-field shots of scenes greater than the diameter of the full Moon.

“The Sun is a dynamic and active star,” said Paul Haese. “From time to time we see massive prominences that are released from the Sun’s surface. This shot shows a massive prominence that was released on 8 October 2013.”

Winner Photo Editor’s Choice: ‘The Horsehead and Flame Nebulas’, David Fitz-Henry

Steve Grove, Photographic Manager with News Corporation Australia, chose David Fitz-Henry’s shortlisted image for this year’s ‘Photo Editor’s Choice’ award.

The Horsehead Nebula is a dark nebula in the constellation of Orion. It lies approximately 1,500 light years from Earth. The Flame Nebula lies to the lower-left of the image and is part of the same molecular cloud complex.

Winner Animated Sequences – Scientific category: ‘Shine On’, Peter Ward

Scientific animations are short sequences that have an obvious scientific purpose. These sequences usually require great skill and/or perseverance in first obtaining the data and then in collating them to reveal an aspect of scientific merit.

Peter Ward’s winning entry is a time-lapse sequence of the solar chromosphere. Individual sequences were taken over several weeks, around Easter 2014.

Winner Animated Sequences – Aesthetic category: ‘Dance of the Dishes’, Alex Cherney

Aesthetic sequences are animations that are visually pleasing in some way, where the use of appropriate music and editing is encouraged, but always with a strong astronomical component.

“Very smoothly edited and professional-looking sequences of the [CSIRO] Australia Telescope Compact Array telescopes at work, and I especially like the fish-eye sequences of the dishes nodding at each other as they scan the Milky Way. Great stuff,” commented David Malin.

David Malin Awards 2014 on show

Apollo 11’s Magic Orange Carpet Ride

By Glen Nagle
CSIRO Astronomy and Space Science

orangefootprint

It’s funny the things you remember from your childhood. For me, my two outstanding memories are of those first steps on the Moon and a bright orange carpet.

This week marks the 45th anniversary of Apollo 11’s landing on the surface of the Moon. At 12.56pm on the 21st of July 1969, an estimated 600 million people around the world were transfixed to their black and white television sets as astronaut Neil Armstrong placed his booted foot on the grey lunar soil. The grainy images relayed around the world from dish-like antennas in Australia.

I was one of those 600 million viewers, then 7 years old, but today working as the visitor centre manager at the Canberra Deep Space Communication Complex (CDSCC) and the CSIRO’s Parkes radio telescope better known to most people as – The Dish.

I still remember that moment as if it happened yesterday. Our school in the southern suburbs of Sydney didn’t have a television set and I was determined to watch the astronauts walking on the Moon, so I nagged my parents to let me stay home and see it. They agreed to let me be ‘home alone’ as long as I didn’t move from this bright orange carpet mat they had placed in front of the TV along with some milk and biscuits.

Needless to say, I never moved. I sat glued to the screen watching those amazing images. Never in my wildest dreams did I think that 45 years later I could sit in my office in either Canberra or Parkes and look out the window to the very dishes that brought those images into my lounge room.

The original dish from the Honeysuckle Creek Tracking Station in the Australian Capital Territory (later relocated to CDSCC), captured the first 8½ minutes of the moonwalk and beamed that ‘one small step’ around the world. The Parkes dish came in at that point and handled the last two hours of the astronaut’s activity on the Moon’s surface.

It was certainly a magic carpet ride to that young boy all those years ago. It was a moment that set me on a path to loving science and sharing that passion with other people. I’ve been fortunate to have met a number of the astronauts who walked on the Moon and many of the people behind the scenes at the tracking stations that made that mission and those TV images possible.

I ache though for the generation growing up now who never experienced that moment and hope that one day they get to take their own magic carpet ride, be it orange or any other colour.

exhibitThat next ‘giant leap’ will probably be as we take our first steps on the surface of Mars sometime in the 2030s.  I hope that a memory like that will take them from their childhoods and on a journey to places that they never thought possible.

The Parkes Radio Telescope’s visitor centre is currently running an exhibition of photos from the Apollo missions that will run until the end of September 2014.

Entry to the centre is free and is open 7 days, 8.30am to 4.15pm.

Radio astronomy: the next generation

Game changing, fascinating, exciting, inspiring. There was no shortage of positive adjectives used to describe the science that will be possible with the Square Kilometre Array (SKA) in the Twitter chatter that exploded last week.

Most of the world’s most influential radio astronomers were gathered in Giardini Naxos – at the base of Mount Etna, Europe’s most active volcano – for the ‘Advancing Astrophysics with the Square Kilometre Array’ conference*. And there was an explosion of tweets, presentations and conversations on the scientific direction that the world’s largest radio telescope will take.

The astronomers were there to discuss the ‘science case’ for the SKA, a 130-chapter document that will highlight the types of science – from cosmology, pulsar science and gravitational wave astronomy to cosmic magnetism and the search for life beyond our Solar System – that will be done with the observatory.

The last SKA science case was published 10 years ago. The updated case, to be released later this year, will reflect the advances in radio astronomy and engineering that have been made over the past decade.

Dr Naomi McClure-Griffiths was one of the CSIRO astronomers who participated in the meeting: “For me, the highlight was seeing the incredible breadth of science that will be done with the SKA.

“The SKA will be a very powerful telescope set to answer some essential questions about the Universe. But as [fellow CSIRO astronomer] Ray Norris reminded us, probably the most exciting discoveries will be things we have not yet thought of,” says Naomi.

There were several SKA science ‘headlines’, which included:

  • By using pulsars, rapidly spinning neutron stars, the SKA is expected to be able to detect gravitational waves, conduct tests of gravity in extreme conditions, and further our understanding of how gravity works
  • Through studying the emission of neutral hydrogen, the SKA will ‘look’ back to the Epoch of Reionization, the early period of the Universe when stars and galaxies started to form, and even earlier to the Dark Ages, and
  • By mapping cosmic magnetic fields beyond current capabilities, the SKA will advance our understanding of star formation and the structure of the Universe, the ‘cosmic web’.

And some of the first science images taken with ASKAP – our own SKA precursor telescope – were unveiled.

But it wasn’t just science with the next generation of radio telescopes getting everyone excited.

“I have been going to SKA meetings for over 10 years but this one felt very different,” says Naomi. “There’s a new, young, fresh community getting involved in SKA science now and they are coming up with ideas that we hadn’t dreamed of 10 years ago.”

“I definitely came away from the week feeling renewed excitement about all that the SKA will bring.”

The ‘Advancing Astrophysics with the Square Kilometre Array’ conference was held in Giardini Naxos, Italy, 8-13 June 2014.

*Fortunately the conference wasn’t held this week: Mount Etna started erupting on 15 June.


Mystery Planets

Worlds discovered to date. Image: exoplanets.org

Worlds discovered to date. Image: exoplanets.org

It seems that nearly every week there is another announcement of a new planet being discovered somewhere – out there! Most are gas giants, some are smaller rocky worlds. Most are in close orbits to their stars while a handful sit in the so-called “Goldilocks” or “habitable” zone.

These planets follow the “rules” of planetary formation models, but then there are some worlds that break those rules.

One recent announcement for a new ‘exoplanet’ (planets that orbit stars in other solar systems) was the discovery of a large ‘rocky’ world that is estimated to be more than twice the size of the Earth. Nothing unusual in that.

An artist concept shows the Kepler-10 system, home to two rocky planets. In the foreground is Kepler-10c, a planet that weighs 17 times as much as Earth and is more than twice as large in size. Image: NASA

Designated Kepler-10c, the planet though has scientists a bit mystified because their calculations show that its mass is 17 times more than that of the Earth. A planet of that mass should gravitationally attract an envelope of gases around it to form a much larger, perhaps ‘Neptune-sized’ world or larger, but Kepler-10c is just this massive rock in space.

Orbiting its star every 45 days, temperatures on the sun-facing side would make it a place too hot to support life. Located 560 light-years from Earth in the constellation Draco, astronomers are at a loss to figure out how the planet would have formed without turning into a gas giant.

This isn’t the only mystery world however.

Tucked away in the Cygnus constellation about 2,300 light years from Earth, the planet Kepler-413b is literally on a wild amusement park ride. The planet’s 66 day orbit is like a rollercoaster, travelling in a wave-like pattern around its parent stars, a pair of orange and red dwarfs. The planet also wobbles on its axis up to 30 degrees over only an 11 year period, compared to the Earth which wobbles on its axis over 26,000 years.

Astronomers think that the gravitational influence of other planets in this solar system or possibly a third nearby star may be exerting an influence.

Kepler-413b is a Neptune-sized world, 65 times the mass of the Earth. Due to its close but erratic orbit to the binary stars, temperatures would most likely be too hot to allow liquid water to exist making the planet an unlikely candidate for supporting life as we know it.

At the other end of the scale is a world so far away from its sun-like star that is should be nothing more than a frozen ball of rock and ice. Planet HD 106906b however is a gas giant world, 11 times the mass of Jupiter.

The planet is challenging planetary formation models. At a distance over 20 times further away from its star than Neptune is from our sun, HD 106906b is only a relatively young world at around 13 million years old.

Detected by its infrared signature, HD 106906b is still quite hot at 1,500 degrees Celsius due to the residual heat from its formation. The mystery is how such a planet could have formed so far away from the star it is orbiting and the disk of dusty and rocky material surrounding that star where planets would normally coalesce.

It’s possible that the planet may have formed in a completely separate cloud of material around another nearby but failed star. As its new parent star travelled through the galaxy it was caught by its gravity in a sort of celestial adoption process.

Then there are those planets that are orphans.

CFBDSIR2149 is a free-floating planet seemingly with no nearby star. Around four to seven times the mass of Jupiter, the planet is 100 light years from Earth and appears to be travelling through the galaxy in parallel with the AB Doradus star cluster.

Free-floating objects like CFBDSIR2149 are thought to form either as normal planets that have been booted out of their home systems, or as lone objects like the smallest stars or brown dwarfs.

These are a handful of examples of the planets that don’t quite fit the scientific models out of the multitude of solar system that have been discovered so far.

Surveys suggest that there could be as many as a trillion planets in our galaxy, actually outnumbering the stars in the Milky Way. Just based on what has been found so far, there are likely to be many more weird, wonderful and mysterious worlds out there just waiting to be discovered.


Our ACES team aces it

ASKAP_PRINT

CSIRO’s Australian SKA Pathfinder telescope, ASKAP.

When our team saw what they’d done with our ASKAP telescope in Western Australia, they almost fell off their chairs.

After just a few months of commissioning, they have the telescope functioning like one that’s been around for years. (Well, almost.)

Think of the sculptor Michaelangelo. He started with a block of marble and, after hacking away, ended up with ‘David’.

There must have been a moment when he thought: “It’s a real statue now”.

The ASKAP Commissioning and Early Science (ACES) team has reached that point.

The proof? A couple of images that have blown astronomers’ minds.

The circles indicate the nine overlapping ‘beams’ (regions of sky the telescope ‘sees’) from which the image was created: the large circle is an enlargement of beam number 6, showing details of the radio sources.

First, this image showing a number of distant radio galaxies (the white dots).

It was made from nine overlapping regions of sky, or ‘beams’, captured simultaneously.

To you, it may look like just … a bunch of dots. But hardened scientists were left speechless by the lack of imaging ‘artefacts’ in each ‘beam’.

They swooned over the dynamic range (50,000 to 1). And they were delirious over the size of the image, ten square degrees on the sky — 50 times larger than the full Moon.

(When ASKAP achieves its full 30-square-degree field of view, we’ll have to give them tranquillisers.)

As if that weren’t enough, a lovely image of the galaxy NGC 253 gave further cause for joy.

This one basically assures us that ASKAP is giving a proper ‘weighting’ to the different frequencies of radio waves that were used to make the image.

This is ASKAP’s first image of cold atomic hydrogen gas — the ‘fuel’ for making stars — in a galaxy. It’s essentially a snapshot, with the data having been taken over a mere 11 hours. It stacks up extremely well against an image made with a much longer observation time on our trusty Compact Array telescope.

“We did it so easily,” said one astronomer. “Everybody was dancing.”

The colours represent information about the velocity of the gas, and show that the galaxy is rotating: the blue regions are moving towards us and the red regions are receding.

After you’ve built a telescope, you can’t just flip a switch and have everything work perfectly, first time.

Commissioning is the process of getting all the complicated telescope systems to work together properly, and understanding the characteristics of the data the telescope produces.

ASKAP incorporates novel technology, such as the phased array feeds and the third axis of rotation. It takes a while to ensure that these systems are operating as planned.

In fact, it is ASKAP’s two new features that are delivering the goods.

As the telescope tracks radio sources, the third axis of rotation keeps the phased array feed in a fixed orientation to the sky. And, as we’ve explained elsewhere, that helps make really high-quality images.

As the ACES team leader Dr Dave McConnell said, “We’ve never had a telescope like this before”.

Go team!

Bringing the Sexy Back to the Future

Bringing sexy back to the future of space travel

In the effort to return American astronauts to space by launching them from their own soil, there has been a recent flurry of announcements and unveilings for a variety of new spacecraft to do just that.

Only one of the five recently exhibited space vehicles belongs to NASA, the rest have been developed by the private sector under the United States’ Commercial Orbital Transportation Services (COTS) program.

COTS invited companies to design and develop full flight hardware and launch vehicles to provide cargo and eventually human-rated spacecraft for services to low-Earth orbit and the International Space Station.

Since the retirement of the US Space Shuttle in 2010, America has lacked a capability to launch its own astronauts into space, instead relying on the Russians to get them up to the space station and back again.

While a number of companies applied for funding under the COTS program, only two have advanced to the point where they have actually been launching missions – Orbital Sciences Corporation and Space X. Two others organisations, Boeing and the Sierra Nevada Corporation have vehicles still in development and are yet to make their first test flights.

Each of these companies are taking cues from earlier vehicle concepts in a sort of ‘back to the future’ approach to spacecraft design, but with 21st century tweaks and innovations that are likely to be ‘bringing the sexy back’ to the age of space travel.

Unveiled in a ‘live’ webcast event was Space X’s Dragon 2 capsule. Founded by PayPal entrepreneur Elon Musk, Space X has been building on the success of its Falcon 9 rocket and Dragon cargo capsule which has already flown several missions to the International Space Station (ISS) and returned experiments and other materials safely back to Earth.

The Dragon 2 vehicle takes that experience and has designed a fully operational vehicle with the capability to launch up to seven astronauts into space. The reusable vehicle, which will be able to fly up to 10 missions before major refurbishments are required, uses the latest in touch screen technology and flight avionics.

Spacecraft of the 1960s needed over 1000 dials, gauges, buttons and switches for the astronauts to operate the vehicle. Space X’s design incorporates all of the systems needed for propulsion, navigation, communication, diagnostics and life support onto a few easily accessible screens with all the information and controls at the crew’s fingertips.

Everything about Space X’s Dragon 2 capsule is designed with comfort and style in mind. From the relatively spacious crew area and mood lighting, down to the reclining, leather-look, embossed launch seats.

The biggest innovation in Dragon 2 is in the way it will to return to Earth using a rocket powered descent system that will give the vehicle the ability to land virtually anywhere on the surface of the planet.

Space X is not alone in developing next generation spacecraft for human spaceflight. Boeing continues to forge ahead with the development of its CST-100 vehicle.

Again harking back to the Apollo-style capsule design, the CST-100 will, like Dragon 2, be capable of taking up to seven astronauts into space. But Boeing has set its sights further than just having a spacecraft that can reach the space station and plans extended capabilities that could allow the CST-100 to stay in space for long periods or even provide transport services to a private space station or space hotel being proposed by one of its partners Bigelow Aerospace.

While ground tests continue, Boeing has indicated that an initial test flight may occur in mid-2015.

Orbital Sciences Corporation in the meantime is concentrating its efforts on the next flight of its Antares rocket and Cygnus cargo vehicle to ISS. Cygnus draws its design from the Multi-Purpose Logistics Module that NASA flew on the Shuttle during the construction of the orbiting ISS outpost.

Capable of taking up to 2,700 kilograms of crew supplies, spares and science experiments to the space station, the highly automated vehicle helps to fill the gap in low-Earth orbit supply missions following the Shuttle’s retirement.

While capsules are the way that Space X and Boeing are planning to take American astronauts back into space, the era of space shuttle-like winged vehicles is not over.

The Sierra Nevada Corporation is developing the Dream Chaser, a winged, lifting-body spacecraft that its team says ‘will provide a flexible, credible, affordable solution for International Space Station crew transportation and a viable path to the future of human space flight operations for NASA, international and commercial space applications’.

Dream Chaser is the sports car version of NASA’s Shuttles , with enough room for seven astronauts and the capability to glide back to Earth and land on any conventional runway.

Continuing a series of test flights and ongoing design modifications, Sierra Nevada is aiming for its first orbital test launching using the existing Atlas V rocket in November 2016.

While the COTS program has spawned a whole new industry of private enterprise space travel services, NASA hasn’t been sitting around waiting for them to provide the new taxi service for their astronauts.

They have continued work on the Orion Multipurpose Crew Vehicle (MPCV). Orion was born from the ashes of the cancelled Constellation program which aimed to design and build different rockets to launch astronauts and cargo to space. Orion MPCV again takes it design from the reliable capsule concept but with its sights set well beyond Earth orbit.

Orion MPCV is part of NASA’s roadmap for returning astronauts to the Moon and visiting an asteroid by the mid-2020s. In a variety of configurations, mated to other models it could also be used to take the first human crew to Mars in the 2030s.

The first unmanned test flight of Orion is scheduled to take place later this year as part of a three year test program that will ultimately lead to the first mission by humans away from planet Earth in over 40 years sometime in 2017.
