Hubbles went up April 24, 1989. It cost a total of 1.5 billion dollars to correct a mirror. Its mirror was not put in correctly. The spaceship Endevour went up to correct this in 1993.
Hubble gave a birthday present to us of photos of Terantula Nebula, which is a space nursery (NGC 2070). NGC 2070 is less then three million years old.
In 2001, Dennis Tito, paid $20 million to become the first tourist in space. The first vacation in space lasted seven days in 2002. Seven people have vacationed on the International Space Station so far.
In 2012 Virgin Galactic start being the first space tourism ship ferrying people back and forth in space. The maximum speed so far is Mach 3, about 33,000 miles. The Bigalow Aerospace will provide the first orbiting space station, which will be inflatable. This space station will begin its flight in 2014. As early as 2016 we may see people staying in this space station.
Stars are found and put into order. However many of the stars are in more then one catolog as their catologs are similar. Now there are so far four catologs made up. The first catolog is NGC which.stands for the New General Catolog. The second one is known as UGC which is an abbreviation for Uppsala General Catalog. The next one is PGC which is Principle Galaxy Catolog. The last one is 2C which is the second Cambridge catolog of radio.sources.
The Andromeda galaxy is 2.6 lightyears away. It is also known as Messier 31, NGC 454, PGC 2556 or NGC 224. It is also is a Nebula. It is the nearest Spiral Galaxy, however not closest Galaxy.
The largest galaxy near us
Triangulum galaxy and 30 smaller galaxiesMilky Way contains most dark matter out of these galaxy
The Spitzer Telescope found these galaxies.
These are also known as Einstein-Rosen bridges. Einstein postulated wormholes curvatures in space-time. They exist in something known as Cosmic Foam according to Stephan Hawking. Cosmic foam is the smallest substance within the universe.
Tiny blackholes blink in and out of the universe. They are too small and brief be seen. Cosmic Strings, which Richard Gott had proposed in 1991, weave throughout the universe.
Julian Barbour added to Einsteins theory of relativity.Gravity results from theory. Dark matter and energy fill in the 96% that the theory doesn't cover. Scientists have not taken an interest in this. They haven't because Julien wants to totally remap the universe by it. In 1975 joined with Bruno Bertotti a physicist. They developed "best-matching" motion of object measured by distance gone rather that change on grid. In 1982 they came up with new theory of relativity.
Back in the 1970s astronomers realized outer parts of galaxies were rotating faster-pulled by more gravity dark matter came in again. Hans Westman, Sydney university physicist, analyzed forgotten theory developed by German mathematician, Hermann Weyl. Astronomers now have much evidence that dark matter exists it will take a great deal to prove otherwise.
David Wiltshire, from University of Cantenberry, in New Zealand, thinks the illusion of dark matter is mysterious time is only relative to location there is no Universal time. Sean Gryb, joined by Tim Loslowski, were set to find Barbours mistake but that never happened.
In 2008 Barbour won official research grant.
The Milky Way, our galaxy, is a barred spiral galaxy. Andromeda, which is our neighboring galaxy, is 2.5 million lightyears away, is a spiral galaxy as well. There are eliptical galaxies as well. Quasars, these look like stars,however they are active galaxies as well. There are an infinite number of galaxies. The afore mentioned are only a few.
Most galaxies contain a supermassive blackhole in the center.
Nebula are clouds of gas and dust however mostly hydrogen.They either occur in stars births or deaths. The Crab Nebula is a supernova remnant and has at least 1054 flares. Some are star emissions that glow. Nebula are generally reflective, dark and form planetary rings.
Open clusters and globular clusters are spread throughout space. They are both two types of star clusters. The major difference is how tightly they are packed together. Open clusters are more like countrsides, where everything is relaxed and spreadout. While globular clusters are more like star cities, where everything is tightly packed and close together.
