What do stars emit besides heat and light?

They emit: gamma rays, radio waves, and x-rays. Some stars emit T.V. rays


What type of wave does the chandra x-ray detect?

Chandra X-ray Observatory detects X-rays, which are a type of electromagnetic wave with higher energy and shorter wavelength than visible light. X-rays are emitted by extremely hot and high-energy objects in the universe, such as black holes, neutron stars, and supernova remnants.


Why do astronomers use x-ray telescopes to study supernova explosions and black holes?

Different types of electromagnetic waves provide different kinds of information. Specifically, black holes will emit large amounts of x-rays.


Which types of celestial body emits x rays?

There are plenty of celestial bodies that emit xrays - while others scatter, reflect, or alter the energy of electromagnetic radiation into the x-ray range. Sources that emit x-rays include pulsars or neutron stars, the accretion disks of black holes, stars - particularly ones with certain types of companions, stellar remnants such as from supernovae, entire galaxies (with and without active nuclei) and to some extent, even the universe as a whole; though some of this is generally attributed to mechanisms which heat gas. There are even x-ray sources within the solar system, including the Moon, since not all of its observed x-ray emission is simply reflected from the Sun.


What are the rays detected from TVs?

CRT and plasma TVs emit x-rays, which can be hazardous.


Do pulsar emit pulses of x-rays?

yes, some do.


Do pulsars emit pulses x rays?

yes, some do.


Do pulsars emit pulses of x rays?

yes, some do.


How are black holes most easily identifed?

Black holes do not emit light, so black holes can not be seen this way. But black holes emit X-rays, but stars are not hot enough to emit X-rays. When black holes suck up stars, energy goes to the black hole, and come out as X-rays.


How can a black hole emit X-rays?

Black holes can emit X-rays when matter falls into them and gets heated up to very high temperatures, producing intense radiation that includes X-rays. This process is known as accretion, where the matter spirals into the black hole's gravitational pull and releases energy in the form of X-rays.


What other forms of radiation may come from stars?

Stars can emit various forms of radiation, including ultraviolet, X-rays, and gamma rays. Sun-like stars emit primarily visible light and some ultraviolet radiation. More massive stars can also emit X-rays and gamma rays.


A gas heated to millions of degrees would emit?

A gas heated to millions of degrees would emit X-rays.
