Why The Hubble Space Telescope

There are eight planets in our solar system. The ones closest to the sun, are hotter than the ones that are farther away. Neptune is the farthest planet from our sun, that is in our solar system. Because of this distance, Neptune is the coldest planet in our solar system. Neptune is the 4th largest planet in the Solar System. It is bigger than Mercury, Venus, Earth, and Mars.The

The layers of extraordinarily compressed hydrogen are in a state so extreme that it has never been produced in Earth. The pressure is so great that the hydrogen molecules inside

For the low-mass stars, the expansion to the red giant phase will begin when about 90% of its hydrogen has been converted to helium. During the contraction of its core, a complicated sequence of events occurs. The shrinkage required to produce the energy radiated by the large giant causes the core to shrink to the dimensions of a white dwarf, while hydrogen continues to burn by nuclear fusion in a thin shell surrounding the core. This shell provides most of the energy that is radiated away by

The sun is a big, hot ball of hydrogen gas which enables us to feel the sun’s heat and see its brightness. Every second of every day, the sun transforms over 700 million tons of hydrogen into over 600 million tons of helium. The sun produces so much energy that we can see the sun’s brightness and feel its heat. Hydrogen fusion takes place in the Sun’s core and the gas is heated by the energy that is discharged above the core. Ultimately the gas becomes less dense and the heat from below turns the gas

The surface of both of these bodies is known to be cold because of the lack of atmosphere and their position with reference to the Sun.

2. An interstellar cloud of gas known as an H-II region is mainly composed of what?

The life cycle of the Sun starts like all stars with a cloud of dust and gas made up of mostly hydrogen. If the cloud cools, it will shrink because of the gravitational pull between the particles

thousands of small icy bodies orbit the sun. The planet appears to be typical of Kuiper Belt objects--only

It is no secret that the earth’s sun is “special” to say the least. Some would say it was designed to be unique to help sustain life on planet earth. However, other nearby stars were not designed to sustain life. One example would be the star Proxima Centauri. This star recently had a short increase in radiation, known as a flare. This flare caused the star to become a thousand times brighter for ten seconds. Earth’s sun also has flares, but they are much smaller. When Proxima Centauri is at its brightest point it is still ten times brighter than our suns largest flare. This is just one example of how special our sun really is.

Scientists found a new plant that has this star that’s so hot that they disbelieve there could be any molecules living on this planet named “Kelt-9b”. The founders go to the Ohio State University in Columbus, Ohio the team tells us how this planet is three times bigger than Jupiter, and the star that lives as its next door neighbor is nearly twice as hot as our own sun. The planet moves around the sun like star every one and a half earth days one side of the planet is locked into a face to face with the star which makes the face of Kelt-9b be around 7,820 degrees Fahrenheit. For a long time scientists have been focused on finding small planets by cool stars because technology today it’s easier to study atmospheres of planets potentially find

The size also awards it the title of being bigger than Eris, a mini-planet that circles Neptune in the Kuiper Belt.

much a star wobbles or goes around the centre of gravity of the exoplanet and star, the violent wobbles must conclude that 51 Pegasi b is a Jupiter sized exoplanet. Hd209458 b is also a Jupiter sized exoplanet, which may have been determined using the calculation or the wobble method, having similar affects to its host stars light spectrum as 51 Pegasi b has on its host star. Astronomers are unsure whether the exoplanet named Kepler 22b is a larger Earth or more of a mini Neptune, as it is boarder line between a rocky planet and a gas dwarf.

Neptune is the eighth planet from the sun and is farthest from the sun and was discovered in 1612 by Galileo. It is located approximately 2.8 billion miles from the sun and completes one full orbit every 165 years, and has only . Neptune is an ice giant which means it is mainly made up of elements heavier than helium and hydrogen such as carbon, sulfur, nitrogen, and oxygen. Neptune has 13 moons, six of which were discovered by Voyager 2. A fourteenth was found in 2013, it is about 12 miles wide and is close to 100 million times fainter than the faintest star.

On April 9, 1998, Cornell University astrophysicist Martin Harwit published his discovery of the presence of massive amounts of water in the Orion Nebula. This was the first time that water has been found in a star-forming region. The find demonstrates that water plays a vital role in star formation. In addition, this discovery implies that water is prevalent in space. Harwit speculates that the water acts as a coolant, by carrying heat away from the condensing clouds. It is believed that this process is necessary to slow down the particles in order to allow the compression of the particles into new stars. 6

Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.
