This composite X-ray (blue)/radio (pink) image of the galaxy cluster Abell 400 shows radio jets immersed in a vast cloud of multimillion degree X-ray emitting gas that pervades the cluster.

Sounds From Space

Space is mostly quiet. Data collected by telescopes is most often turned into silent charts, plots, and images.

These new views showcase the dual nature of the star AG Carinae, which was the target of the NASA/ESA Hubble Space Telescope's 31st anniversary image in April 2021.

Galaxies can receive and exchange matter with their external environment thanks to the galactic winds created by stellar explosions.

Scientists connect the dots between where planets form and what they're made of.

A 900-year-old cosmic mystery surrounding the origins of a famous supernova first spotted over China in 1181AD has finally been solved, according to an international team of astronomers.

Rapid Increase In Global Light Pollution

Global light pollution has increased by at least 49% over 25 years, new research shows.

It's challenging to make predictions, especially in astronomy. There are however, a few forecasts astronomers can depend on, such as the timing of upcoming lunar and solar eclipses and the clockwork return of some comets.

Scientists achieved first light with the Band 1 receiver on August 14, 2021

Forget about online games that promise you a "whole world" to explore. An international team of researchers has generated an entire virtual UNIVERSE, and made it freely available on the cloud to everyone.

As their name suggests, ultradiffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low surface brightness, making them very difficult to detect.

Surprise: The Milky Way Is Not Homogeneous

Astronomers from the UNIGE have observed the composition of the gases in our galaxy and have shown that, contrary to the models established until now, they are not homogeneously mixed.

The current target launch date for the James Webb Space Telescope is 18 December 2021.

Could dying stars hold the secret to looking younger?

Astronomers have found dramatic evidence that a black hole or neutron star spiraled its way into the core of a companion star and caused that companion to explode as a supernova.

Using a supercomputer simulation, a research team at Lund University in Sweden has succeeded in following the development of a galaxy over a span of 13.8 billion years.

A Spectacular Portrait of Centaurus A

A spectacular portrait of the galaxy Centaurus A has been captured by astronomers using the Dark Energy Camera mounted on the VĂ­ctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile.

By taking advantage of a natural lens in space, astronomers have captured an unprecedented look at X-rays from a black hole system in the early universe.

Galaxies Pump Out Contaminated Exhausts

A team of astronomers led by Alex Cameron and Deanne Fisher from the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) used a new imaging system on at the WM Keck Observatory in Hawaii to confirm that what flows into a galaxy is a lot cleaner than what flows out.

Unravelling The Mystery Of Brown Dwarfs

An international team, led by the UNIGE, has investigated five astronomical objects that could help us understand the mysterious nature of brown dwarfs
