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".

This beautiful video is a look at a map of the Milky Way that was just released. The video description explains in detail about how the image was made:

This video takes a close look at a new image of the Milky Way released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). The APEX telescope in Chile has mapped the full area of the Galactic Plane visible from the southern hemisphere for the first time at submillimetre wavelengths — between infrared light and radio waves — and in finer detail than recent space-based surveys.

The APEX data, at a wavelength of 0.87 millimetres, shows up in red and the background blue image was imaged at shorter infrared wavelengths by the NASA Spitzer Space Telescope as part of the GLIMPSE survey. The fainter extended red structures come from complementary observations made by ESA's Planck satellite.

Astronaut Tim Peake posted a time lapse video from the International Space Station (ISS) that caught a particularly striking view of lightening as it flew over Earth. According to the caption, all these lightening strikes happened in a matter of minutes:

Flying from North Africa over Turkey towards Russia in this timelapse (this is speeded up; travelling about 5500 km would take around 10-12 minutes, covered here in 30 seconds).


As the ISS orbits the Earth astronauts living in the space station have the chance to take amazing time lapse video like this and others.

What are these glorious golden space swirls? According to NASA, who captured this video with the Solar Dynamics Observatory (SDO), this happened when a dark solar filament erupted and caused a chain reaction.They call these cascading magnetic arches because what you see here is a lot of particles spinning around the sun's magnetic field lines. 

Here's a video where you can see what a dark solar filament looks like. The darker area, almost in the shape of a circle is it. Filaments are plasma held above the sun's surface by magnetic forces.
