Neutron stars are remnants of collapsed star cores that have undergone a supernova explosion. Pulsars are an extremely dense type of neutron star that spin at regular intervals, sending blinking beams of light out from their magnetic poles and into the universe. Because pulsars blink with exception...
A 3D illustration of a neutron star in the nebula. (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery explosion known as a supernova. After such an outburst, the cores of these former stars compact into an ultradense object with the mass of...

aThe collapse of a star may produce a White Dwarf or neutron star - a star, whose matter is so dense that it continually shrinks by the force of its own gravity. 星的崩溃也许生产一个白矮星或中子星-星,问题是很密集的它由力量重力它本身连续地收缩。[translate]...
What is the mass of the neutron star? Sun: The sun is the most important source of light and heat on the planet 'earth'. Hence, life on the earth is possible. The followings are the properties of the sun: radius of the sun isR=695,500km ...
The theory is that some stars explode when their density increases to a particular point; they “collapse” and sometimes a supernova(超新星)occurs. The collapse of a star may produce a “White Dwarf(白矮星)”or a “neutron star”--- a star whose matter is so dense that it continually...
Can a black hole be inside a star? Most black holes form from the remnants of a large star thatdies in asupernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.) What are the largest stars in our galaxy?
This energy, expelled into space, is what we see as starlight. The fusion process begins when two hydrogen nuclei smash together to form a particle called the deuteron (a combination of a positive proton and a neutral neutron). Deuterons readily combine with additional protons to form helium....

This explosion leaves behind a “remnant” in the form of a compact object – i.e. aneutron star– and a cloud of gas and dust that is ionized by the energy of the explosion. TheVeil Nebulais a prime example of a Supernova Remnant, as seen in this image captured using a small tele...
