The post Australia from orbit appeared first on Australian Science.
]]>One of the many things which Hadfield has been doing is to keep the tradition set by previous astronauts of taking fantastic photographs of our planet from above. In a Reddit AMA session a couple of months ago, he mentioned that Australia “looks the coolest” from orbit, being fond of the textures and colours of the Australian Outback. So here, for your visual pleasure, are some of the most beautiful pictures of Australia taken from high, high above by Chris Hadfield. Enjoy!
Adelaide by night, glittering like a jewel.
“The Outback is full of scary faces, staring up in forbidding horror.”
Smoke clouds from the bush fires, as seen from above.
Coffin Bay national park.
Dry lakes in the Outback, including one which is being used for farming. Quite ingenious.
King George’s Sound. Hadfield notes that “Charles Darwin got off the Beagle and hosted a dance here in February, 1836.”
Melbourne harbour.
Beautiful smeared colours of a dry lake bed.
The ocean off the coast of Perth. Evening sunlight catches the waves and ocean currents, making them visible.
Jagged lines of the Outback.
Folded rock formations created by tectonic activity in the Outback. Caught by the morning sunlight, they really stand out.
A river delta, showing a host of gorgeous colours.
A big dry lake somewhere in the Outback.
Beautiful blue seas off the Perth coast.
“A lot of the Australian Outback looks like somebody spilled something on it.”
The city lights of Sydney.
An ominous looking smoke cloud in Western Australia.
A shot of the Outback looking very much like a Jackson Pollock painting.
Floodwaters pouring into the Coral Sea near Rockhampton. You can see all the murky brown silt from the river as it disperses into the tides.
“A splash of dry salt white on seared red in Australia’s agonizingly beautiful Outback.”

NASA’s Kepler mission has found a star system which has not one, but two possibly terrestrial planets in its habitable zone.
Whether either or both of Kepler-62’s optimally positioned planets actually has water is beyond the technical capabilities of the Kepler and other telescopes. Kepler works by detecting the very slight dips in light coming from a star caused by a planet passing by, relative to the telescope’s line of sight.
Sometimes the best way to learn more about nature is to try and recreate it. That happens to be exactly what happened when a group of roboticists were looking at insects…
They found that the moth moved its abdomen in direct response to its shifting visual environment. “If the pattern is rotating up (clockwise), the moth would raise its abdomen up (counterclockwise),” says study co-author Jonathan Dyhr, a University of Washington biologist. “The moth was raising or lowering its abdomen to counteract the movement.”
To celebrate the 23rd anniversary of the Hubble Space Telescope’s launch into orbit, NASA have released a brand new and frankly beautiful image of the iconic Horsehead Nebula. Phil Plait explains more…
The Horsehead itself is the site of ongoing star formation. The dense gas and dust inside the nebula is collapsing to form stars, and, at the same time, the edges are being eroded away by the fierce ultraviolet light of Sigma Orionis. The top of the Horsehead is acting a bit like a shield, protecting the material beneath it, which is why it’s taken on that umbrella-like shape. You can see more sculpted pillars of material around the sides, too, like sandbars in a stream.
Ants are fascinating little creatures, and a team of Swiss researchers have been studying the goings on inside a colony of them – by tracking them with barcodes!
Analyzing the color codes, they found that younger ants were more likely to work nursing the young, and older ants were more likely to be foragers. In general, they watched ants transition from nursing to cleaning to foraging as they age, but there’s a lot of individual variation in how quickly these transitions took place.
Finally, everyone’s favourite astronaut, Commander Chris Hadfield aboard the ISS answers an interesting question. What happens if you wring out a wet cloth in zero gravity? Click the link to watch the video!
Two Nova Scotia high school students, Kendra Lemke and Meredith Faulkner, submitted this experiment to Canadian Space Agency and got to see astronaut Chris Hadfield actually test it out on the ISS. The results are seriously extraordinary and you need to see them.

The post New light on dark matter: space station magnet attracts praise appeared first on Australian Science.
]]>Nobel prizewinner Samuel Ting, early Thursday morning (March 4, 2:00 AEDT), announced the first results from the Alpha Magnetic Spectrometer (AMS) search for dark matter. The findings, published in Physical Review Letters, provide the most compelling direct evidence to date for the existence of this mysterious matter.
In short, the AMS results have shown an excess of antimatter particles within a certain energy range. The measurements represent 18 months of data from the US$1.5 billion instrument.
The AMS experiment is a collaboration of 56 institutions, across 16 countries, run by the European Organisation for Nuclear Research (CERN). The AMS is a giant magnet and cosmic-ray detector complex fixed to the outside of the International Space Station (ISS).
The visible matter in the universe, such as you, me, the stars and planets, adds up to less than 5% of the universe. The other 95% is dark, either dark matter or dark energy. Dark matter can be observed indirectly through its interaction with visible matter but has yet to be directly detected.
Cosmic rays are charged high-energy particles that permeate space. The AMS is designed to study them before they have a chance to interact with Earth’s atmosphere.
An excess of antimatter within the cosmic rays has been observed in two recent experiments – and these were labelled as “tantalising hints
