and may be close to collapsing into a neutron star What is slightly larger than the moon? ZTF J1901+1458 is one of the smallest white dwarf stars that astronomers have ever seen. The dying husks of a Sun-like star are just 133 light-years away by a series of ground and space telescopes. In a study published Wednesday in the ทางเข้า slotxo journal Nature, researchers detail the discovery and nature of ZTF J1901+1458, so named because it was discovered by the Zwicky Transient Facility, an observatory-based observation of the sky. California star Palomar, which searches the region for any object with sudden changes in brightness. It's quite an extreme star. A white dwarf is formed when a star that is eight times more massive than the Sun or smaller reaches the end of its life. when the fuel runs out They began to collapse. But it's quite controversial. This initial collapse caused the star to swell to enormous sizes and become a red giant (like the famous Betelgeuse star).This process also cools the star slightly and shrinks the core. which will release an enormous amount of energy However, it begins to lose its outer layer and is left with a very dense core, a white dwarf.
