", The All-Sky Automated Survey for Supernovae (ASAS-SN) searches for changing spots of light in the sky, and caught the glowing feature when it brightened in June. But identifying the supernova was only the beginning of the mystery: Now, the researchers are exploring what could be powering the massive explosion. Study co-author Ido Burger described it as "very special" in many other ways, apart from its size and brightness. Pagkakaiba ng pagsulat ng ulat at sulating pananaliksik?

The researchers announced today (Jan. 14) that the bright spot is 3.8 billion light-years from Earth, in the sky at the border of the southern constellations Indus and Tucana. Supernovae are absolutely huge, the most powerful event in the Universe we know of.

"We're following this with many different telescopes; with Swift Space Telescope, the Hubble Space Telescope and many ground-based telescopes from around the world to basically see how it fades with time," Shappee, the Carnegie Observatories astronomer, said. Understanding these massive explosions is one of the big puzzles in physics today, Gal-Yam said, and this new supernova is useful because it pushes the limits of current models, and can help differentiate between them.

It's one of the most powerful explosions in the known universe, a source of light so bright that it can - for a few weeks at least - outshine an entire galaxy of hundreds of billions of stars. Future US, Inc. 11 West 42nd Street, 15th Floor, "The feature which makes it the most unique is just its overall luminosity," said Ben Shappee of the Carnegie Observatories in California, one of the researchers who took the first spectrum of the object from a telescope in Chile and a paper co-author. In a single nanosecond, ASSASN-15lh expelled more energy than those power plants could produce, operating at full capacity, for 2.8 billion years.

After the 14-cm robotic telescopes of the star survey ASAS-SN (which researchers refer to as "Assassin") returned information on the object, the next step was to take a spectrum: By measuring the wavelengths of light that the supernova was putting out, researchers could figure out what it was made of and, potentially, how far away it was. It can't be seen with the naked eye at this distance — but if this object were 8.6 light-years away like Sirius, the brightest star in Earth's sky, it would appear to shine as brightly as the sun, researchers said.

It's in the outer edge of that galaxy, 55 million light years away.

So, this supernova was about 580 billion times brighter than our sun. You may opt-out by.

That magnetic power could heat up the expanding gas and boost the brightness of the explosion.

Dissecting a Supernova: A Star Explosion Post-mortem (Videos), On This Day in Space: Oct. 18, 1963: Félicette Becomes the 1st Cat in Space! A supernova is far more powerful than the sun. Here's what to expect. Last summer, astronomers found the most powerful supernova they had ever seen, an event called ASSASN-15lh. "That gives you a sense of what's powering it and also, as it expands with time, typically for a normal supernova you see deeper and deeper into the object.". Astronomers look at a stellar object and measure its luminosity: the amount of energy it releases per second. 5 days ago. No matter the mechanism, hypernovae are quite rare, and we've only seen a few dozen of them in the past few decades.

And while a hypernova can come from the same source as a supernova (in other words, the death of a giant star) there's some extra special physics that go down to turn a nova from super-mode to hyper-mode.

To be clear, we're not exactly sure what causes a hypernova to be so intense, but we have two main ideas. In fact, such supernovas usually emit only one percent of their total energy in the visible light range. Their report published in the journal Science last week contained a measurement of the total power of this explosion: (2.2+/-0.2) x 1045 Ergs per second. The original object, called the progenitor, either collapses to a neutron star or black hole, or is completely destroyed. Read here why? The energy of ASSASN-15lh is comparable to converting the entire moon to pure energy every 30 seconds.

"Everything that's around you that's not hydrogen or helium is actually made inside of a star and distributed in the galaxy through supernova explosions," Shappee said. And it could quite well be that one model can provide only so much, and the other one can provide a little bit more.".

And way better than supernovae. It's like the universe turned on a couple of 1038 W light bulbs. The super-luminous supernova ASAS-SN15lh is the most luminous ever measured. The supernova ASAS-SN15lh brightened its host galaxy considerably: here, a 2014 false-color view of the galaxy from the Dark Energy Camera in Chile and one from the Las Cumbres Observatory Global Telescope Network in 2015, after the supernova's peak. Let's start by getting rid of ergs.

Astronomers have detected the explosion of the largest ever supernova. No, that title goes to something called a hypernova. You will receive a verification email shortly. Please refresh the page and try again. For its few dying days, the supernova is nearly 30 times more luminous than our entire galaxy. A rare Wolf-Rayet star system has been found in our Milky Way galaxy, where stellar winds created by the stars sculpt dust into a glowing tail. Supernovae are so bright that when they go off in our own galaxy, they can sometimes be seen during the day.

Here, an artist's illustration visualizes what it would be like to see the supernova from an exoplanet located about 10,000 light years away.
