C.E, Chinese astronomers spotted a supernova and dubbed it the "guest star." The National Science Foundation’s (NSF) Víctor M ...

A study of supernova remnant SNR 0519-69.0 using the Chandra X-ray telescope, Hubble and more has narrowed down its age to several hundred of years. The remnant is located in the "Large Magellanic ...

If these weird episodes are the result of an orbiting white dwarf, a type of stellar remnant left behind when a star with around the mass of the sun dies, then this dead star is performing an ...

"The large volume of data from Rubin will give us a sample of all kinds of Type Ia supernovas at a range of distances and in ...

The most plausible outcome is this brazen white dwarf (the spent core of a sun-like star), which is about one-tenth the mass of our sun. It's shedding its dense, outer layer and triggering these ...

The interior of this type of star is incredibly dense. To put this in perspective, a volume of white dwarf material equal to a teaspoon would weigh several tons! In such a condensed state ...

Our sun is a lonely star. At least half the stars in our galaxy have binary companions. This was nicely illustrated in the ...

A Triple Star System Yields an Unusual Surviving Star Unlike our Sun, which exists alone, at least half of the stars in our ...

T Cor Bor and the “Blaze Star,” it’s a recurrent nova (repeating new star) caused by a white dwarf star in its orbit that explodes almost like clockwork every 80 years or so. However ...

Chilean astronomers have observed a cataclysmic variable known as V1425 Aql. As a result, they have found that this system ...

This is also unprecedented behavior for a black hole. If these weird episodes are the result of an orbiting white dwarf, a type of stellar remnant left behind when a star with around the mass of the ...
