A collaboration between scholars from the University of Edinburgh (UK) and the University of Bologna has identified the oldest inactive galaxy – which means that…
A giant star has just exploded as a supernova and is beginning to be visible in the sky
Image credit: X-ray: NASA/CXC/SAO; Optical: Detlef Hartmann; Infrared: NASA/JPL-Caltech Excitement is growing among astronomers as it is the closest supernova explosion in nearly a decade.…
BlackGEM telescopes begin search for sources of gravitational waves
Three Belgian-Dutch telescopes have started operating at ESO’s La Silla Observatory in Chile. This so-called BlackGEM network will scan the southern skies for cosmic events…
The first radio detection of a type Ia supernova sheds light on the origin of these explosions
Type Ia supernovae occur when a white dwarf, the ‘corpse’ of a star similar to the Sun, absorbs material from a companion star and reaches…
Astronomers discover an unusually low-density super-Earth
Researchers from the Center for Astrobiology and other international centers have discovered a super-Earth with unusually low density. The explanation seems to lie in its…
The James Webb telescope detects signs of “supermassive stars” of unusual dimensions
If the signs detected by the prodigious space telescope are confirmed, a star up to 10,000 times larger than our sun would have existed in…
Red supergiant star Batelgeuse increases its brightness and could explode as a supernova
Betelgeuse is the closest red supergiant star to our planet, and one day it will explode as a supernova. In recent days it has increased…
They discover a planet the size of Earth that is covered in volcanoes
The study also found that there are two other planets in the star system, called LP 791-18 b and c. The researchers suggest that the…
Galactic bubbles are more complex than estimated
Astronomers have revealed new evidence about the properties of giant bubbles of high-energy gas that extend far above and below the center of the Milky…
A new study puts a definitive age on Saturn’s rings: they are very young
A new study led by University of Colorado Boulder physicist Sascha Kempf has provided the strongest evidence yet that Saturn’s rings are remarkably young, potentially…
