Our Sun will become a white dwarf in about 7 billion years. At that point, it will no longer produce energy through nuclear fusion, having exhausted its fuel (hydrogen and helium). Just like the ...

Technically, the sun is a G-type main-sequence star — specifically, a G2V star. The "V" indicates that it is a dwarf, Tony ...

Using radial velocity measurements, an international team of astronomers has identified a second planet orbiting a nearby M-dwarf star known as Gliese 536. The newfound alien world turns out to be at ...
