This picture of a green and red aurora was taken on September 26, 2013, from the International Space Station. The colours of the aurora borealis depend on which atoms the solar storm excites. Green auroras appear when charged particles from the solar wind crash with oxygen atoms in Earth’s atmosphere and produce green photons; red auroras occur when the particles collide with nitrogen atoms or when there are lower-energy oxygen collisions, producing red photons.

Remember Philae? That little lander that was targeting comet Rosetta?

It was very big news around two months ago... Sadly, Philae landed incorrectly in a rather awkward position due to technical failings. After all, it was trying to land on the harsh, unstable, deteriorating/burning up surface of a comet. It bounced three times to a site away from the targeted position and ended up in a shady place with insufficient sunlight to recharge its energy reserves. And so it died out after 60 hours of touchdown.

Recent tabloids have now reported that Philae is missing! Scientists from the European Space Agency have tried to analyze the images that Philae returned but things just keep on getting more ...

The study, titled "CFT 70 (Countermeasure and Functional Testing in Head-Down Tilt Bed Rest Study)," aimed to learn more about how human bone and muscle might deteriorate in space. According to Drew Iwanicki, who took part in the study and who is pictured above, he experienced some serious headaches because of increased blood pressure to his head. His spine went through some serious pain, and staying horizontal was difficult. However, as soon as the bed was tilted to the vertical position, after 70 days of course, his legs felt heavier and his heart started to beat at 150 BPMs.

Since its discovery in 2010, researchers have been trying to solve the mystery of dark streaks that appear and disappear seasonally on the planet's surface (shown above). Scientists are now claiming that this phenomenon, known as the recurring slope lineae, is caused by a bath of saltwater. What is still unknown, however, is where the water is coming from, or if the chemistry is even right for supporting life.

At roughly 6 billion kilometers from Earth, the image you see to your right is the farthest images ever taken.

The New Horizons spacecraft captured its first images on August 16 of the remote icy world nicknamed Ultima Thule (a traditional name of distant places beyond the known world), confirming that New Horizons is on track for its January 1 flyby around Pluto. With about 160 million kilometers to go — roughly the same distance as Earth is from the sun — the tiny world appears as no more than a faint speck in the probe’s camera.

Officially named 2014 MU69, Ultima Thule is part of the Kuiper Belt, a thick disk-shaped zone containing space debris left over from the formation of the planets 4.6 billion years ago. By sending New Horizons to t ...
