Hubble Helps Discover a New Type of Planet Largely Composed of Water
Researchers have found evidence for the existence of a new type of planet they have called a “water world,” where water makes up a large fraction of the entire planet. These worlds, discovered in a planetary system 218 light-years away, are unlike any planets in our Solar System.

Hubble Captures Three Faces of Evolving Supernova in Early Universe
Three different moments in a far-off supernova explosion were captured in a single snapshot by the NASA/ESA Hubble Space Telescope. The progenitor star exploded more than 11 billion years ago, when the Universe was less than a fifth of its current age of 13.8 billion years.

A Cosmic Cobweb
Nowadays, all galaxies and galaxy clusters are thought to be dominated by dark matter — an elusive quantity whose nature astronomers are still working to determine. Abell 611, the glowing galaxy cluster shown in this Hubble image, is no exception. In fact, Abell 611 is a popular target for investigating dark matter, in part because of the numerous examples of strong gravitational lensing visible amongst the cluster’s intricate web of galaxies.

Webb and Hubble Capture Detailed Views of DART Debris
Two of the great observatories, the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope, have captured views of a unique experiment to smash a spacecraft into a small asteroid. NASA’s Double Asteroid Redirection Test (DART) impact observations mark the first time that Webb and Hubble were used to simultaneously observe the same celestial target.

Spiralling Stars Provide a Window into the Early Universe
Astronomers have been bemused to find young stars spiralling into the centre of a massive cluster of stars in the Small Magellanic Cloud, a satellite galaxy of the Milky Way. The outer arm of the spiral in this huge, oddly shaped stellar nursery — called NGC 346 — may be feeding star formation in a river-like motion of gas and stars. This is an efficient way to fuel star birth, researchers say.
