Known as Cepheid variables, the stars have positions and young ages that indicate a warp to the galaxy's arm. This was previously suggested by observations of dust but had not been shown by the presence of stars.

A single "runaway" star in a distant star cluster could explain how a massive supernova avoided collapsing into a black hole, leaving behind a remnant object instead.

Visualized through supercomputers, the violent dance of intergalactic gas, stars, dust and dark matter forms a large spiral galaxy like our own Milky Way. A few smaller galaxies are ‘eaten’ along the way.

In this simulation, 2 neutron stars weigh in at 1.4 and 1.7 solar masses and are separated by only 11 miles. Intense tidal forces pull the stars apart as they spiral towards each other and the black hole is formed amidst the chaos.

Using satellite data, researchers located "grounding lines" (points underneath glaciers where melting begins) and determined these lines were retreating further away from the sea each year. The West Antarctic glaciers are seeing the highest melt rate

After 40 years of observation, NASA and University of California researchers agree that melting of the West Antarctic Glacier has passed the point of no return. It contains enough ice to raise sea levels ~4 feet, but could take centuries to melt.
