Supernova Bubble Expands in New Hubble Time-Lapse Movie
Though a doomed star exploded some 20,000 years ago, its tattered remnants continue racing into space at breakneck speeds – and NASA’s Hubble Space Telescope has caught the action. Expanding supernova bubble…
Unexpectedly Calm and Remote Galaxy Cluster Discovered
Cluster is farthest ever spotted not disrupted by violent collisions with other galaxy clusters. Astronomers have discovered the most distant “relaxed” galaxy cluster to date — the farthest cluster ever spotted that…
Cosmic Web Lights Up in Darkness of Space

New Light on Strange Lava Worlds
Lava worlds, massive exoplanets home to sparkling skies and roiling volcanic seas called magma oceans, are distinctly unlike the planets in our solar system. Lava world – artistic interpretation. Image…
Improving Detection of Gravitational Waves
A Cardiff University undergraduate has collaborated with academics from the US on a project to improve gravitational waves detectors at the Laser Interferometer Gravitational-Wave Observatory (LIGO) as part of a…
Exoplanet TRAPPIST-1: Insights into Atmosphere and Star
A new study of the intriguing TRAPPIST-1 exoplanetary system has demonstrated the complex interaction between the activity of the system’s star and its planetary features. Astronomers led by a team…
The Universe Caught Suppressing Cosmic Structure Growth
Scientists expect large cosmic structures to grow at a certain rate as the universe evolves: dense regions such as galaxy clusters would grow denser, while the void of space would…
