The Hubble Space Telescope took this image of a star that looks like it's inside a blue bubble. NASA says the blue bubble is actually a nebula formed around 20,000 years ago. This is how it's described on the Hubble's website:

The distinctive blue bubble appearing to encircle WR 31a is a Wolf–Rayet nebula — an interstellar cloud of dust, hydrogen, helium and other gases. Created when speedy stellar winds interact with the outer layers of hydrogen ejected by Wolf–Rayet stars, these nebulae are frequently ring-shaped or spherical.


According to NASA, these type of stars don't last very long (in terms of bodies in space at least). It'll only be around for a "few hundred thousand years".

History was made Wednesday when the European Space Agency successfully landed a spacecraft on a comet for the first time ever.

"We are the first to do this - and that [achievement] will stay forever." said Jean Jacques Dordain, Director General of ESA.



The comet, 67P/Churyumov–Gerasimenko, orbits, the sun every 6.45 years. It is 2.1 miles wide by 2.4 miles long.

Rosetta first launched in 2004 to research the comet, and it didn't arrived at its destination until this past August. On Wednesday morning, Philae first separated from the probe to attempt a landing.

Researchers are hoping to learn more about the origins of the solar system and whether or not comets could have brought water and life to Earth. Watch an ESA animated explanation of Rosetta's journey to the comet and it's surface mission below.
