Neutron stars are created when massive stars reach the ends of their lives and are composed of the densest matter in the known universe.
All in all, there are many different types of stars, ranging from tiny brown dwarfs to red and blue supergiants. There are even more bizarre kinds of stars, like neutron stars and Wolf-Rayet stars. And as our exploration of the Universe continues, we continue to learn things about stars ...
Neutron stars are one of the most mysterious wonders in the universe. Their extreme densities hint at new and exotic physics at work within. Gravitational waves could be the key to unlocking their secrets. In particular, a first detection of gravitational waves from rapidly-spinning, deformed ...
The discovery will confirm the theories of what [happens] to giant stars when they reach the end of their lives. That's important because supernovas are responsible for the spread of life-givingelementsacross the Universe, and the new data will help refine our understanding of how this happen...

This is done either through the formation of a planetary nebula or a supernova. In this way, stars produce and distribute heavier elements such as carbon, nitrogen, and oxygen in the universe. The Sun is the closest star to Earth; however, many other stars are visible at night. One of ...
Types of Black Holes Artist concept of a black hole and its surroundings: The blackened circle is the event horizon, and the egg-shaped region is the ergosphere. Photo courtesy NASA There are two types of black holes: Schwarzschild: Non-rotating black hole Kerr: Rotating black hole The...
Types of Stars Main-sequence stars: These stars are bright because they are fusing hydrogen together to make helium. Our sun and the star Sirius are both main-sequence stars. The main-sequence stars stay in the main sequence for approximately 10 billion years. Red dwarf stars: Red dwarf ...
New-type universities,whose "system and policies"are based on those of"president accountability system under the leadership of the party committee",are the inevitable result of the popularization of higher education. "Ought to be state university model "should include at least the following 5 ...
