A barred galaxy with two arms that twist in the Universe is known for its intriguing features. The galaxy, dubbed NGC 3583, is located 98 million light-years away from the Milky Way. Back in 1975, the galaxy encountered quite the event when two supernovae exploded. In 2015 a similar incident occurred again, turning NGC 3583 in one of the most intriguing galaxies so far.
The Supernovae Features and Significant Details
Until now, scientists found a few distinct ways of how a supernova can form. In the case of those two supernovae, the explosions emerged from two independent binary star systems in which the galactic remains of a Sun-like star (white dwarf) was gathering material from its companion star.
Feasting off of its companion, the white dwarf gorged on the resources until it was too much for it to contain it. When it reached its maximum point, the star fell inward before crashing outward in a brilliant supernova. The Hubble Telescope succeeded in capturing NGC 3583’s both supernovae events.
When supernovae explode, they sent some jets of matter into space at approximately 9,000 to 25,000 miles/s. These jets make much of the material in the Universe, such as iron, which is also part of our planet. Studies claim that most supernovae are triggered by one of two fundamental mechanisms: the sudden gravitational feel of a massive star’s core, or the immediate re-ignition of nuclear fusion in a degenerate star.
In the first class of incidents, the space object’s temperature is increased enough to trigger runaway nuclear fusion, entirely obstructing the star. Possible causes are the addition of material from a binary companion through a stellar merger or accretion. Supernovae can also send lots of solar masses of material at speeds up to several percents of the velocity of light.
