The Value of Astronaut Photography of Earth
Earthlings were spoiled when Chris Hadfield turned his camera to Earth. The astronaut, just returned in May from a five-month mission to the International Space Station, uploaded dozens of pictures of Australia to his Twitter feed and other social networks. His observations ranged from the whimsical — “Jackson Pollock would have been even further…

Neutron star glitch needs new theories to explain it
Neutron stars are some of the strangest and least understood objects in the entire Universe. Over 1.5 times the mass of our whole solar system, squeezed into an object comparable in size with a city, these curious objects wield titanic gravitational fields and, often, immense magnetic fields. They’re also so incredibly dense that it’s difficult…

Shenzhou 10: another step in China’s ‘Long March’ into space
The colorful and polished launch of Shenzhou 10 confirms that China has come of age as a spacefaring nation. At 19:40 AEST on Tuesday June 11 (17:40 local time) three ‘yuhangyuan’, Chinese astronauts, embarked on China’s sixth crewed space mission. This second mission to Tiangong 1, the Chinese space station, is a credible step in…

An Animated Visualization of Every Meteorite Since 861 AD
Carlo Zapponi is data visualization designer at Nokia, who has created an amazing animation of the meteorites that have struck the earth. Only 3% of all recorded meteorites were seen falling since 861 AD. 34,513 have been recorded, only 1,042 have been seen falling. Now you can click any of the fallen meteorites at the image below, also…

Weekly Science Picks
At the top of my list this week would have to be the ISS Commander Chris Hadfield from Canadian Space Agency wringing out a wet towel in zero gravity. If you haven’t watched it yet. Do it now. The explanation behind what happens is more in depth than “magic”. Cmdr Hadfield is right when he…

It’s a small world after all
What we know of exoplanets has developed at the same time as the technology which we use to discover them. This is, in my opinion, the most exciting thing about the entire field of study. For instance, when we first started spotting planets around alien suns, we found huge gas giants. Hot jupiters, extremely massive…

Postcard from Spitzer: weather on 2M2228 is hot and cloudy
Long distance weather reports are now a commonality. The report for 2MASSJ22282889-431026 is somewhat unusual. It forecasts wind-driven, planet-sized clouds, with the light varying in time, brightening and dimming about every 90 minutes. The clouds on 2MASSJ22282889-431026 are composed of hot grains of sand, liquid drops of iron, and other exotic compounds. Definitely not the first…

Andromeda and the 13 Dwarfs
Astronomy is quite notorious for being full of things we don’t entirely understand. Sometimes it really does feel as if the closer we look at the Universe, the less it makes sense. One thing in particular which seems to constantly evade our understanding is the way in which galaxies work. A lot of very smart…

Interstellar travel: how to spot a ‘starman’ going by
Massive objects moving at near light speeds do not occur naturally in the universe as we know it. If we detect such objects it is a reasonable to assume they are artificial artifacts from advanced intelligent life. This according to Garcia-Escartin and Chamorro-Posada, authors of a recent paper, is a low-cost, sure-fire way of searching…

Searching for Life on Titan
Discovered in 1655 by Dutch astronomer Christiaan Huygens, Titan is one of Saturn’s 62 moons, named for a race of giants in Greek myth who were Saturn’s brothers and sisters. Over 5000 km in diameter, it’s roughly twice the size of our own Moon and is one of the largest moons in our solar system,…
