The Sun is very much a main sequence star, in the G-type category (G2V to be precise). It’s been fusing hydrogen for 4.6 ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a planetary nebula designated ...

New research led by W. M. Keck Observatory Instrument Scientist and astronomer Grant Hill has confirmed what scientists have long suspected—WR 104 comprises two massive stars: a Wolf-Rayet star and an ...

Stars are born from vast clouds of gas and dust, known as nebulae, that are scattered throughout most galaxies. Over thousands to millions of years ...

Pairing the known age of a white dwarf with the variable age of a main sequence star allows for more straightforward calculations of important parameters like the relationship between a star's age ...

Within this region, also known as N83, there are a number of O-type stars, the brightest, hottest and most massive of main-sequence stars (like the sun), which burn hydrogen at their core.

These bodies with masses between 13 and 75 times the mass of Jupiter (or 1.3% to 7.5% the mass of the sun) are, therefore, much fainter than regular main sequence stars, despite the fact that some ...

leading to a state of equilibrium between gravitational collapse and the energy released during fusion Key fact In a main sequence star, hydrogen nuclei fuse together to form helium nuclei.
