A supernova is one of the most impressive natural phenomena in the Universe. Unfortunately, such events are often brief and transient, temporarily becoming as bright as an entire galaxy and then fading away. But given what these bright explosions which occur when a star reaches the end of its life cycle can teach us about the Universe, scientists are naturally very interested in studying them.
Using data from the Dark Energy Survey Supernova (DES-SN) program, a team of astronomers recently detected 72 supernovae, the largest number of events discovered to date. These supernovae were not only very bright, but also very brief a finding which the team is still struggling to explain. The results of their study were presented on Tuesday, April 3rd, at the European Week of Astronomy and Space Science in Liverpool.....
As noted, these events were very peculiar in that they had a similar maximum brightness compared to different types of supernove, they were visible for far less time. Whereas supernova typically last for several months or more, these transient supernovae were visible for about a week to a month. The events also appeared to be very hot, with temperatures ranging from 10,000 to 30,000 °C (18,000 to 54,000 °F).
They also vary considerably in size, ranging from being several times the distance between the Earth and the Sun 150 million km, 93 million mi (or 1 AU) to hundreds of times. However, they also appear to be expanding and cooling over time, which is what is expected from an event like a supernova. Because of this, there is much debate about the origin of these transient supernovae.

Gas. Stellar gas. Sounds like they need major Pepto Bismol up there.

Seventy-two short-term super-Novae Discover have gravity cosmologists and astronomers baffled. Electric Universe Cosmologists already know why. Novae are an electrical phenomena. Weve even seen cyclic repetiting Novae which in the normal gravity driven Universe is not possible, at all. Electric Universe PING!

Bombs big enough to take out a solar system!
Life as a biological unit is quite tenuous. However, life as a non-biological unit is probably a contradiction in terms.

Interesting that they would wonder what caused these explosions, but not wonder what caused the Universe.
