With the exception of black holes, neutron stars are the densest objects in the universe. As their name suggests, neutron stars are mainly made of neutrons. However, our knowledge about the matter produced during the collision ...

One of the central predictions of general relativity is that a massive object such as a star, galaxy, or black hole can deflect light passing nearby. This means that light from distant objects can be gravitationally lensed ...

Nearly half the stars in our galaxy are solitary like the sun. The other half comprises stars that circle other stars, in pairs and multiples, with orbits so tight that some stellar systems could fit between Earth and the ...

Using data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and ESA's Gaia satellite, astronomers have detected 21 new high-probability extremely low-mass white dwarfs. The finding is reported in ...
At the heart of every resonator—be it a cello, a gravitational wave detector, or the antenna in your cell phone—there is a beautiful bit of mathematics that has been heretofore unacknowledged.
