Most stars of this type are between 200 and 800 times the radius ofour Sun. The very largest stars in our galaxy, all red supergiants, are about 1,500 times the size of our home star. Because of their immense size and mass, these stars require an incredible amount of energy to sustai...
Brown dwarfs are often referred to as "failed stars" because they are heavier than super-Jupiters but not massive enough to trigger ordinary hydrogen fusion at their cores. But something still burns at the hearts of brown dwarfs. An illustration of a super-Jupiter planet orbiting a "failed" ...

Dust grains play a crucial part in galaxy evolution. They aid in the formation of stars and provide the building blocks of rocky planets and life itself. However, the origin of dust is a contentious topic: it remains unclear whether dust is formed in the violent deaths of massive stars. ...

only the effect of gravity but also other physical phenomena, which Habib refers to as the astrophysical "kitchen sink." Simulating both gravity and other physical processes, including the formation of stars, galaxies, and black holes, is essential for a comprehensive understanding of the universe....
