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.
An artist's impression of the Milky Way's big black hole flinging a star from the galaxy's center.
The Jack-o'-lantern Nebula is on the edge of the Milky Way. Radiation from the massive star at its center created spooky-looking gaps in the nebula that make it look like a carved pumpkin.
This new image from the NASA/ESA Hubble Space Telescope captures two galaxies of equal size in a collision that appears to resemble a ghostly face. This observation was made on 19 June 2019 in visible light by the telescope's Advanced Camera for Surveys.
