Astronomers have captured the first-ever visual evidence of awhite dwarf star exploding twice in a remarkable supernova event ...

Algol is not a single star but a multiple-star system, primarily consisting of two main components, Algol A and Algol B, which orbit a common center of mass. A third, fainter star, Algol C, also ...

The newly observed binary system features a cataclysmic variable star, designated GOTO0650, which is in a rarely seen late stage of its evolution. This was also the first major discovery for the ...

Two studies fill in gaps about the cosmos’s ordinary matter. One maps it all, even the “missing matter.” The other details one of its hiding spots.

According to a fairly new theory, white dwarfs can explode twice in a row in certain circumstances. For the first time, we ...

The shattered star at the center was once a white dwarf, a stellar ember no larger than Earth, yet almost as heavy as the Sun ...

Astronomers have captured a jaw-dropping picture of star that exploded twice. It is the first time researchers have obtained ...

Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare “double-detonation” supernova, where an initial helium blast on the star’s surface triggers a ...

In other cases, another member of the system will go on to form a second white dwarf. If gravitational instabilities bring ...

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

This image, taken with ESO’s Very Large Telescope (VLT), shows the supernova remnant SNR 0509-67.5. These are the expanding ...

By looking at the shifting of stars in photos from the New Horizons probe, astronomers have calculated its position in the ...
