Artwork of a black hole seen from an orbiting planet. A black hole is a region of spacetime where the gravity is so powerful that not even light can escape them. They are created when massive stars die. This one is surrounded by an accretion disc of ...

Astronomers have characterized the largest-ever early-Universe radio jet. Historically, such large radio jets have remained elusive in the distant Universe. With these observations, astronomers have valuable new insights into when the first jets form...

Conceptual animation of the opening to a wormhole moving through a nebula. A wormhole (or Einstein-Rosen bridge) is a theoretical 'tunnel' through spacetime, allowed by the theory of general relativity. In principle, a wormhole connects two regions i...

Artwork conceptualising the expanding and accelerating Universe. Since the 1990s, astronomers have known that the Universe is not only expanding, but that the rate of expansion itself is accelerating. This is postulated to occur due to a mysterious d...

Artist's impression of fragments of Comet Shoemaker-Levy 9 approaching and striking the planet Jupiter in July 1994. Fragments of the comet are seen in the foreground, outgassing in the solar wind. Gas of different colours is produced by different el...
