Astronomers have found a white dwarf star surrounded by a gas disk created from an ice giant planet being torn apart by its gravity.
New measurements of the black hole at the center of the Holm 15A galaxy reveal it's 40 billion times more massive than our sun, making it the heaviest known black hole to be directly measured.
A close-up view of an interstellar comet passing through our solar system can be seen on the left. On the right, astronomers used an image of Earth for comparison.
The galaxy NGC 6240 hosts three supermassive black holes at its core.
Gamma-ray bursts are shown in this artist's illustration. They can be triggered by the collision or neutron stars or the explosion of a super massive star, collapsing into a black hole.
Two gaseous clouds resembling peacocks have been found in neighboring dwarf galaxy the Large Magellanic Cloud. In these images by the ALMA telescopes, red and green highlight molecular gas while blue shows ionized hydrogen gas.
