To mark the Death Star being fully operational, Tarkin orders the Death Star to destroy Leia's home world of Alderaan in an attempt to press her into giving him the location of the secret Rebel headquarters; she gives them the location of Dantooine, which housed a now-deserted Rebel base, but Tarkin has Alderaan destroyed anyway as a ...
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs (pc) [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.
However, the first dredge-up occurs soon after a star reaches the red supergiant phase and so this only means that Betelgeuse has been a red supergiant for at least a few thousand years. The best prediction is that Betelgeuse has already spent around 40,000 years as a red supergiant, [18] having left the main sequence perhaps one million years ago.
The star is located in a spiral galaxy named NGC 7610, 160 million light-years away in the constellation of Pegasus. [ 37 ] [ 38 ] The supernova SN 2016gkg was detected by amateur astronomer Victor Buso from Rosario , Argentina, on 20 September 2016.
The positioning had to be precise. The shuttle's nose was raised 200 feet into the night sky so that the rudder could clear 80 feet of space. Endeavour was then turned 17 degrees clockwise to ...
IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula [1] in the constellation Auriga north of the celestial equator, surrounding the bluish, irregular variable star AE Aurigae. It shines at magnitude +6.0.
NGC 253's starburst has created several super star clusters on NGC 253's center (discovered with the aid of the Hubble Space Telescope): one with a mass of 1.5 × 10 6 solar masses, and absolute magnitude of at least −15, and two others with 5 × 10 4 solar masses and absolute magnitudes around −11; [13] later studies have discovered an ...
It is the most massive star that has a Bayer designation. It was only discovered to be (at least) two stars in the past few decades. Both the obscuring clouds and the great distances also make it difficult to judge whether the star is just a single supermassive object or, instead, a multiple star system. A number of the "stars" listed below may ...
