Would we see a gamma-ray burst coming? There are no stars within 200 light years of our Solar System that are of the type destined to explode as a GRB, so we do not expect to witness such an event at...

What happens if a gamma-ray burst hit Earth? A GRB would deplete the ozone layer in the upper atmosphere, allowing harmful UV radiation to reach the ground and thus have dire consequences for life. However, the ground-level ozone caused by the...
How are gamma-ray bursts related to supernovas? A giant stellar explosion has supplied indisputable proof that gamma ray bursts (GRBs) are triggered by supernovae–the explosive collapse of very massive stars into black holes. Can a gamma-ray burst destroy a star? Gamma...
What is the most strongest thing in the universe? Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe. Which...
What is a supermassive black hole? Supermassive black holes are classically defined as black holes with a mass between 0.1 million and 10 billion M ☉. Some astronomers have begun labeling black holes of at least 10 billion M ☉ as...
Is quasar and pulsar the same? The words may sound alike, but the objects aren’t even similar. Here’s the short answer: a pulsar is a star, and a quasar is a galaxy. Is a pulsar a dying star? Pulsars aren’t really...
Are quasars and black holes same? There is a black hole behind every quasar, but not every black hole is a quasar. So yes, in a way, a quasar is simply one face a black hole may show. If you are...
Do quasars emit gamma-ray bursts? Gamma rays are emitted by a wide range of cosmic objects, such as quasars, which are active galaxies with a highly energetic nucleus. The intensity of the radiation emitted from these systems can vary over very...
What is brighter than a supernova? A super-luminous supernova (SLSN, plural super luminous supernovae or SLSNe) is a type of stellar explosion with a luminosity 10 or more times higher than that of standard supernovae. Are quasars more powerful than supernova?...
