(A nebula)
is a cloud of gas (hydrogen) and dust in space. Nebulae are the birthplace biths. There are different types of nebula. An Emission Nebubla such as Orion nebula, glows brightly because the gas in it is energised by the stars that have already formed within it.
(A star)
is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas.
(red giant)
This is a large bright star with a cool surface. It is formed during the later stages of the evolution of a star like the Sun, as it runs
out of hydrogen fuel at its centre.
(red dwarf)
These are very cool, faint and small stars, approximately one tenth the mass and diameter of the Sun. They burn very slowly and have estimated lifetimes of 100 billion years.
(white dwarf)
This is very small, hot star, the last stage in the life cycle of a star like the Sun. White dwarfs have a mass similar to that of the Sun, but only 1% of the Sun's diameter; approximately the diameter of the Earth.
(Black holes)
are believed to form from massive stars at the end of their life times. The gravitational pull in a black hole is so great that nothing can escape from it, not even light. The density of matter in a black hole cannot be measured.
decomposers break down dead things and waste, so I would say that dead animals would not go back into the ground as fast and the nutrients would not go back into the cycle
Explanation:
The Chandra X-ray observatory or CXC for its acronym in English, is an artificial satellite launched by NASA on July 23, 1999. It was named in honor of Indian physicist Subrahmanyan Chandrasekhar, one of the founders of astrophysics, who determined the boundary mass at which white dwarfs become a neutron star. In addition, Chandra means "moon" in Sanskrit.
The Chandra Observatory is the third of the Great Observatories of NASA. The first was the Hubble Space Telescope, the second was the Gamma Compton Ray Observatory, launched in 1991 and already disintegrated, and the last was the Spitzer Space Telescope. Before launching the Chandra Observatory was known as AXAF by the acronym in English of Advanced X-ray Astronomical Facility.
As the Earth's atmosphere absorbs most X-rays, conventional telescopes cannot detect them and a space telescope is necessary for their study.
In 1976 Riccardo Giacconi and Harvey Tananbaum proposed to NASA the idea of the Chandra Observatory, beginning preliminary work at the Marshall Space Flight Center. Meanwhile, in 1978, NASA launched the first X-ray space telescope, the Einstein (HEAO-2).
Despite this, work on the Chandra project continued during the 1980s and 1990s, but in 1992 the ship was redesigned to reduce costs. Four of the twenty mirrors that the observatory was going to dispose of were removed, and an elliptical orbit with which it would reach a third of the distance to the moon was calculated. This eliminated the possibility of being repaired by the space shuttle, but placed the observatory outside the influence of the earth's radiation belts most of its orbit.
