However, despite the rarity of the phenomenon, it is a coincidence because it is after all a distance of thousands of light years between the two events
In the last six weeks, two supernovae have been discovered inside a pale galaxy in the constellation Hercules. This is the first time that astronomers have observed two starbursts in the same galaxy, almost simultaneously, using NASA's Swift Space Telescope. The galaxy named MCG+05-43-16 is 380 million light years away.
In order to illustrate the uniqueness of the event, the astronomers emphasize the fact that the two supernovae are different from each other. Supernova ck 2007, which is a type II supernova event, was caused when the core of the massive star used up its nuclear fuel and collapsed inward. The result resulted in the star exploding into pieces. Supernova ck 2007 was first discovered on May 19 this year.
In contrast, Supernova 2007co (Supernova 2007co, Type Ia event) was caused in a double star system. A white dwarf absorbed many materials from its partner and caused massive nuclear fusion until it exploded as a result. A white dwarf is a tiny, compact star that has finished its combustion process, in fact only the core remains, its size is the size of the Earth but its mass is the mass of the Sun. Supernova co2007 was discovered on June 4 this year.
In most galaxies, one supernova occurs every 25 to 100 years, so it is impressive that two supernovae are discovered in the same galaxy only 16 days apart, says Steven Immler from NASA's Goddard Center. in 2006 Immler used the Swift Space Telescope to photograph two supernovae in the elliptical galaxy NGC 1316 but both were type la supernovae, and they were discovered half a year apart.
The appearance of two supernovae in one galaxy is very rare, they indicate nothing more than a coincidence and do not imply anything about the uniqueness of the galaxy. The two supernovae are thousands of light years away from each other, astronomers observing this galaxy from within, can record the two supernovae exploding hundreds of years apart because the speed of light is a finite speed.

The problem is that by the time the sun is finished, humans will finish the earth and no one will see the end of our sun and the rest of its planets.
There is no doubt that this is a spectacular spectacle. We have been watching supernovae for a long time. It's just a shame that our sun will not reach this state. A supernova requires a star 10 times larger than the sun. In time, its heat will increase and increase until it melts the atmosphere and destroys all the springs and death and us. After that, it will collapse into a red giant and astronomical minutes {tens of millions of years} after exhausting its hydrogen reservoir, the sun ends its life and shrinks to a white dwarf {a star whose core pulls the rest of the star on it } It is compressed to such an extent that it is considered the heaviest object, a matchbox of its material is equal to a billion tons.
So the next time you go to the beach remember the sun will never stay.
Thanks. I accepted the request and changed the title.
The title misses the article: not a difference of thousands of light years between the events, but a distance of thousands of light years in the location of the two supernovae.
And come to the Redeemer.
