T CrB is an example of what astronomers call a recurrent nova. It refers to a variable star that has a pattern of exploding. Astronomers know of about 10 recurrent novas, but T CrB is the closest and the only one it’s possible to see with the naked eye—but only once it’s “gone nova.” 온라인카지노
It may be the closest, but whatever we’re about to see has actually already happened, and many times over. Such is the size of the galaxy that T CrB is 3,000 light years away, which means it takes 3,000 years for its light to reach us. In that time, about 35–40 more outbursts will likely have already happened—and the photons are now on a light-speed journey to us.온라인카지노
T Coronae Borealis (T CrB) recurrent nova system, illustration. This binary system consists of a … [+] white dwarf star and a red giant star. The strong gravitational force of the white dwarf pulls gas from the red giant onto its surface, heating it. When the white dwarf’s surface reaches over 10 million degrees Celsius a thermonuclear explosion is triggered. The majority of the element lithium found in the universe is produced by novae explosions. T CrB is in the constellation Corona Borealis, approximately 3,000 light-years from Earth 신규사이트
