Scientists may have discovered why neutron stars are so bright. It's the stars' strong magnetic field that boosts the production of luminous X-rays.
If so, this could hint at the nature of dark matter.rnArnaud de Lavallaz and Malcolm Fairbairn of King's College London wondered what would happen when dark matter -which makes up most of the mass of galaxies - is sucked into the heart of neutron stars. These stars, the remnants of ...
Double neutron star (DNS) systems in tight orbits are fantastic laboratories to test Einstein’s general theory of relativity. The first such DNS system, commonly known as Hulse-Taylor binary pulsar, provided the first indirect evidence of the existence of gravitational waves and the impetus to bu...
We now know that stars are fueled by nuclear fusion. Each time fusion takes place, energy is released as a by-product. 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 ...
Why do supergiant stars, such as Betelgeuse, have high luminosity? Why is a star called a star? Why are spiral galaxies so bright? Why are there no stars on pictures of the man on the moon? Why are colors produced in planetary nebulae? Why is Rigel blue? Why might astronomers measure ...
There is no exact evidence: the magnetic field is strong interaction in nuclei macroscopic manifestations of another force on; but by this logic the same neutron stars, black holes could explain why the universe has super strong magnetic fields cause. ...
Why are they called the complex numbers? Describe the characteristics that a pyramid must have for it to have an axis of rotational symmetry. Why does Georg Cantor say that the set n and 10n are cardinally the same size? Why is finding the basis for a topological space important?
can escape. Some smaller stars are big enough to go supernova, but too small to becomeblack holes—they'll collapse into super-dense structures calledneutron starsafter exploding as a supernova. But the sun's not big enough for this fate, either: It has only about one-tenth of the mass...
It's possible not enough of their stars explode in supernovas. Some of the biggest, most intense regions of star formation are found in the smallest of galaxies, and scientists believe this is because stars reaching the ends of their lives in the so-called dwarf galaxies are more likely to...
