Hubble captures movie of DART asteroid impact debris
The NASA/ESA Hubble Space Telescope captured a series of photos of rapid changes to the asteroid Dimorphos when it was deliberately hit by a 545-kilogram spacecraft on 26 September 2022. The primary objective of the NASA mission, called DART (Double Asteroid Redirection Test), was to test our ability to alter the asteroid’s trajectory as it orbits its larger companion asteroid, Didymos. Though Dimorphos poses no threat to Earth, data from the mission could help inform researchers how to potentially change an asteroid’s path away from Earth, if ever necessary.

For The First Time Hubble Directly Measures The Mass of a Lone White Dwarf
Astronomers using the NASA/ESA Hubble Space Telescope have for the first time directly measured the mass of a single, isolated white dwarf star – the surviving core of a burned-out sunlike star.

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.
