First Supernova Shockwave Detect By NASA’s Kepler Telescope
March 26, 2016 | EditorsThe second generation of the Kepler Space Telescope called K2 has captured for the first time the shockwave of a supernova explosion. Known as a shock breakout, this flash of energy precedes a supernova and last only about 20 minutes, so catching this is an investigative milestone for astronomers. Read More
Exiled Stars Exploded Ferociously In Intergalactic Space, Hubble Confirms
June 7, 2015 | Editors
The Huge space between galaxies is not completely empty, it is inhabited by some stars which were flung far away from any other galaxies or stars and lost forever in the dark region of intergalactic space. These stars lives in solitude far enough from their nearest neighbors. Read More
Huge Explosion in the Sky Spotted In 1670 Was Actually Rare Stellar Collision
March 24, 2015 | Editors
Some of seventeenth century’s greatest astronomers, including Hevelius — the father of lunar cartography — and Cassini, carefully documented the appearance of a new star in the skies in 1670. Hevelius described it as nova sub capite Cygni — a new star below the head of the Swan. Read More
Ancient ‘Dusty’ Supernova can Give Birth to 7000 Earths

Our universe is pretty big and so are the secrets which it is wrapping around. One such interesting part of our big universe is Milky Way Galaxy. There are so many hidden secrets about it which you would certainly be surprised to hear. Read More
Astronomers Sees Ancient Supernova Split Into 4 Different Ways
March 6, 2015 | Editors
About 9.3 billion years ago, a supernova exploded in our universe. Since then, its light has been traveling the billions of light years it takes to get to our little planet we call home. But in between this supernova and Earth, there happens to be a massive galaxy, within a cluster of galaxies, which has had an interesting effect on the path of the light coming from this exploded star.

Close Pair of White Dwarfs to Collide in Catastrophic Supernova
February 10, 2015 | Editors
Supernovae are rare in occurrence, but at the center of an enigmatic nebula lie two stars that astronomers say will eventually end in a fiery, violent supernova. Astronomers believe that the two stars are set in such a tight orbit that they will merge and cause each other’s explosion and death. Read More
Extraterrestrial Dust Found at the Bottom of the Sea
January 21, 2015 | Editors 1
Supernovae are powerful explosions in space which are triggered when massive stars die. These stellar events forge many different elements — including potassium, iodine, and iron—which are essential for life. But a recent report explains that these events also release heavier elements too — like gold and lead — and radioactive elements — like plutonium and uranium — which counters some of the current ideology.

Question Arises If Massive Supernova will Kill Us All
December 20, 2014 | Editors
Astronomers have been eyeing the Eta Carinae, a huge star weighing 120 times that of the Sun and is dubbed as the “Death Star,” for many years. Social media sectors are alarmed with the fact that the flare that would be generated by the collapse of Eta Carinae could end life on Earth. It is said that the flare would be 100 times bigger than the Earth and could produce a radiation enough to kill all the people in the world. Read More
The Bright Star During the Daytime ~ Supernova Explosion of 1054 AD
November 23, 2014 | Editors 2
When a star dies in a violent, fiery death, it spews its innards out across the sky, creating an expanding wave of gas and dust known as a supernova nebula. Arguably, the most famous of these supernova remnants is M1, also called the Crab Nebula, a blob-like patch visible in low-powered binoculars. Read More
For the First Time, Astronomers Witnessing Nova’s Exploding Fireball
October 27, 2014 | Editors 1
Scientists have experienced a unique astronomical event, that of an exploding Nova Star. The team of astronomers has witnessed the images of a thermonuclear explosion in the form of a fireball coming from a nova star. The astronomers could track down the explosion as it kept expanding. Read More
Will Betelgeuse Become a Second Sun?
July 21, 2014 | EditorsBetelgeuse will explode someday. It lies some 430 light-years from Earth. Yet it’s already one of the brightest stars in Earth’s sky. The reason is that Betelgeuse is a supergiant star. It is intrinsically very brilliant. Read More
The Supernova Zoo
April 3, 2014 | Editors
Astronomers determine a supernova’s type in part by its spectrum and in part by its light curve, a graph of brightness changes. The energy driving a supernova’s rapidly expanding gas comes mainly from three means: the radioactive decay of freshly synthesized elements, typically nickel-56; the shock wave heating the star’s extended hydrogen atmosphere, if present; and the interaction between the supernova’s ejecta and any hydrogen gas in the vicinity.
