In December 2014 and June 2015, as an astronomer I was lucky enough to to visit La Silla Observatory in Chile. Part of the European Southern Observatory, La Silla is home to dozens of working telescopes, including the 1.2m Swiss Telescope, on which I worked. While there I turned my camera to the skies, taking nearly 10,000 photos. This video is the result.

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".
