What happens after a star explodes?

It was a new year, and the sky was doubly red.

A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size of the main body, unlike other moons in the solar system. The scenario also could support Pluto's active geology and possible subsurface ocean, despite its location at the frozen edge of the solar system.

Billions of years from now, only one of these two galaxies will remain.

Taking advantage of a cosmic 'double lens,' astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present age.

Physicists have proposed a solution to a long-standing puzzle surrounding the GD-1 stellar stream, one of the most well-studied streams within the galactic halo of the Milky Way.

Collaborative work by amateur and professional astronomers has helped to resolve a long-standing misunderstanding about the composition of Jupiter's clouds. Instead of being formed of ammonia ice -- the conventional view -- it now appears they are likely to be composed of ammonium hydrosulphide mixed with smog.

Hidden patterns in electric propulsion plasma beams could help ensure the success of long-term space missions.

Scientists recently discovered that the giant 'conveyer belt' currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal of the carbon here on Earth, including the carbon in our bodies, likely left the galaxy at some point!

Astronomers pinned down the origins of at least one fast radio burst, a brief and brilliant explosion of radio waves emitted by an extremely compact object. The team's novel technique might also reveal the sources of other FRBs.

What do you think this is?

Is this what will become of our Sun? Quite possibly.
