Neutron stars pack an extremely strong gravitational pull, much greater than Earth's. This gravitational strength is particularly impressive because of the stars' small size. When they are formed, neutron stars rotate in space. As they compress and shrink, this spinning speeds up because of the ...
A possible evolutionary history of neutron stars is delineated, ranging from star formation through supernova explosions, X-ray and pulsar stages to an eventual pulsar turnoff via spin alignment, or magnetic field decay. New is the emphasis that there should be two populations of pulsars, the ...

When you look up at the night sky, how do you feel? Sometimes, if it's a clear night without any clouds and you're far away from any city lights, you can lift your head up and take in a beautiful view of countless stars. Although we know they're massive, swirling clouds of extre...
creating the densest matter we can directly observe. One teaspoon ofneutron starwould weigh as much as a mountain. Neutron-packed stars rotate faster than blender blades and make the universe’s strongest magnets. They have solid crusts surrounding liquid cores containing material shaped like spaghe...
The measurement of hot gas pressure in galactic clusters has shown that there must be about five to six times as much dark matter as all the stars and gas we observe [source: Chandra X-ray Observatory]. Otherwise, there wouldn't be sufficient gravity in the cluster to prevent the hot gas...
“We were excited to catch the very early optical light from this short gamma-ray burst – something that is still largely impossible to do without using a robotic telescope. But when we analyzed our exquisite data, we were surprised to find we couldn’t explain it with the standard fast...
So how do we test the speed of gravity? 为了测量引力的速度 In order to test the speed of gravity, 你需要一个既能发出引力波 you need to have a system that emits both 又能发出光的系统 gravitational waves and light. LIGO在2017年探测到的 The colliding neutron stars detected by LIGO 碰撞...
All we can do is evolve the educational system to adapt. Take away the stage of where they need to memorize definitions. Your voice search is capable of doing that now. We hope our education systems evolve to truly ask them to dream. And in this age of big data, ask them to dream ...
"It was predicted fifty years ago that we should observe a pile-up in the number of white dwarfs at certain luminosities and colors due to crystallization and only now this has been observed." Crystallized white dwarfs aren't just a stellar curiosity; their quantum makeup is unlike anything ...
