How does a star go from supernova to black hole? Those stars that do morph into black holes usually go through the death throes of a core-collapse supernova — but some are too enormous for even that. They directly collapse into...
Can a black hole go supernova? A black hole or a neutron star may have merged with a normal massive star and caused it to explode in a supernova, according to Caltech’s Dillon Dong and colleagues. Dong says that such explosions...
Is a kilonova stronger than a supernova? (A kilonova is an even stronger type of explosion than the typical supernova that happens when large stars blow up.) The kilonova’s power comes from colliding superdense neutron stars, where bizarre physics reigns. What...
How powerful is a supernova explosion? When supernovae explode, they jettison matter into space at some 9,000 to 25,000 miles (15,000 to 40,000 kilometers) per second. These blasts produce much of the material in the universe—including some elements, like iron, which...
What is hotter than a supernova? The hottest thing that we know of (and have seen) is actually a lot closer than you might think. It’s right here on Earth at the Large Hadron Collider (LHC). When they smash gold particles...
How hot is a supernova? The temperature in a supernova can reach 1,000,000,000 degrees Celsius. This high temperature can lead to the production of new elements which may appear in the new nebula that results after the supernova explosion. What is...
Is a supernova hotter than the Sun? Supernovae are stars that contract so much that they eventually explode. They may reach temperatures of 3 billion degrees Celsius (that’s 300 times hotter than the sun) right before they explode (Dickin, 2005). How...
What is a kilonova explosion? Astronomers may have spotted the afterglow from an epic cosmic event known as a “kilonova.” Kilonovas occur after the collision of two hyper-dense neutron stars, which are the remnants of stars that have died in supernova...
Is a gamma-ray burst more powerful than a supernova? Gamma-ray bursts (GRBs) are short-lived bursts of gamma-ray light, the most energetic form of light. Lasting anywhere from a few milliseconds to several minutes, GRBs shine hundreds of times brighter than a...
What is the most powerful hypernova? Not only is SN2016aps the most powerful supernova ever spotted, it is the longest one we have found. What is stronger hypernova or supernova? A hypernova — sometimes called a collapsar — is a particularly...
