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…
