Astronomers have measured what they believe is the most massive neutron star ever seen, and it's "almost too massive to exist." Neutron stars are what remains when a star goes supernova and dies, making
(CNN) — Astronomers have detected the most massive neutron star ever, and it almost shouldn't even exist. Neutron stars are the smallest in the universe, with a diameter comparable to the size of a city
It's 15 miles across, with a mass of more than twice the sun. Astronomers using the Green Bank Observatory in West Virginia have observed the most massive neutron star ever measured. The newly discovered

The Earth and Moon are almost a double world. The Moon is so large compared to the size of Earth that its gravitational pull affects our planet’s motion. One of these effects is known as axial precession.
This simulation shows the radiation emitted from a binary black hole system. In principle, we should have neutron star binaries, black hole binaries, and neutron star-black hole systems, covering the allowable
So in the middle of the 20th century, after we first invented radio telescopes, we found all sorts of surprises. It turns out that the universe is pretty loud, full of all kinds of interesting radio sources.
