As the material collapses under its own weight, massive stars may form in the center, and their ultraviolet radiation ionizes the surrounding gas, making it visible at optical wavelengths.
Interest : They may stretch over hundreds of light years across. A light year is essentially the distance that light can travel in one year]]> 2016-09-21 03:10:22 UTC https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125279863 savion_ferguson https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125280635 Formation : A protostar is a very young star that is still gathering mass from its parent molecular cloud. The protostellar phase is the earliest one in the process of stellar evolution. For a one solar-mass star it lasts about 1,000,000 years.
Interesting Fact : a contracting mass of gas that represents an early stage in the formation of a star, before nucleosynthesis has begun.]]> 2016-09-21 03:17:47 UTC https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125280635 savion_ferguson https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125282205 Formation : Giant Star is formed when a star like our sun, or one larger, runs out of its hydrogen fuel. Inside a star, hydrogen atoms are combined together to form helium atoms.
Interesting Fact : A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) sta of the same surface temperature]]> 2016-09-21 03:36:31 UTC https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125282205 savion_ferguson https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125283574 Formation : Supergiant stars are the largest stars in the universe. They can be thousands of times bigger than our Sun and have a mass up to 100 times greater
Interesting Fact : A red giant star is a dying star in the last stages of stellar evolution. In only a few billion years, our own sun will turn into a red giant star, expand and engulf the inner planets, possibly even Earth]]> 2016-09-21 03:57:37 UTC https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125283574 savion_ferguson https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125283934 Formation :  Nuetron stars are created when giant stars die in supernovas and their cores collapse, with the protons and electrons essentially melting into each other to form neutrons
Interesting Fact : Neutron stars are thought to form by the gravitational collapse of the remnant of a massive star after a supernova explosion, provided that the star is insufficiently massive to produce a black hole.]]> 2016-09-21 04:03:46 UTC https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125283934 savion_ferguson https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125284559 Fomation : After a star sheds its outer layers and forms a planetary nebula, it will leave behind this core, which is the remnant
white dwarf. A white dwarf is formed when a low-mass star has exhausted all its central nuclear fuel and lost its outer layers as a planetary nebula
Interesting Fact : a small very dense star that is typically the size of a planet. ]]> 2016-09-21 04:14:29 UTC https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125284559 savion_ferguson https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125286499 Formation :  A black dwarf is all that is left after a white dwarf star burns off all of its heat
Interesting Fact : A black dwarf is a white dwarf that has cooled down to the temperature of the cosmic microwave background, and so is invisible. Unlike red dwarfs, brown dwarfs, and white dwarfs,black dwarfs are entirely hypothetical.]]> 2016-09-21 04:39:35 UTC https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125286499 savion_ferguson https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125287867 Formation : A white dwarf is formed when a low-mass star has exhausted all its central nuclear fuel and lost its outer layers as a planetary nebula
Interesting Fact : Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars]]> 2016-09-21 04:57:12 UTC https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125287867 savion_ferguson https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125289829 Formation : The second type of supernova occurs at the end of a single star's lifetime. As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova.
Interesting Fact : A supernova is an explosion of a massive super giant star. It may shine with the brightness of 10 billion suns!]]> 2016-09-21 05:23:05 UTC https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125289829 savion_ferguson https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125290231 Formation : Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space.
Interesting Fact : A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing , not even particles and electromagnetic radiation such as light , can escape from inside it]]> 2016-09-21 05:28:53 UTC https://padlet.com/savion_ferguson/hwuxtfyvt9vm/wish/125290231
