Perfect explosion! 2 Neutron stars collide, spark amazing spherical Kilonova explosions

[ad_1] Scientists have revealed that the collision of Neutron stars causes spherical Kilonova explosions. This contradicts the earlier theory. Stars are celestial objects millions of years old floating in space. When a star runs out of fuel, its core collapses, crushing together every proton and electron into a neutron. This results in the creation of the densest object known to man, a Neutron star – an object with the mass of a sun squished down to the size of a city, as per NASA. When two neutron stars collide, it results in their merger and causes an explosion, known as a Kilonova.Earlier it was believed that the Kilonova explosion result from a Neutron star merger were flattened discs. However, this new study contradicts it. The study, done by astrophysicists at the University of C...

NASA missions probe game-changing cosmic explosion

[ad_1] On Dec. 11, 2021, NASA's Neil Gehrels Swift Observatory and Fermi Gamma-ray Space Telescope detected a blast of high-energy light. On Dec. 11, 2021, NASA's Neil Gehrels Swift Observatory and Fermi Gamma-ray Space Telescope detected a blast of high-energy light from the outskirts of a galaxy around 1 billion light-years away. The event has rattled scientists' understanding of gamma-ray bursts (GRBs), the most powerful events in the universe. For the last few decades, astronomers have generally divided GRBs into two categories. Long bursts emit gamma rays for two seconds or more and originate from the formation of dense objects like black holes in the centers of massive collapsing stars. Short bursts emit gamma rays for less than two seconds and are caused by mergers of dense ...

This bizarre object is FASTER than light? What did NASA Hubble Space Telescope catch?

[ad_1] NASA Hubble Space Telescope thought it spotted something that should not exist, which was travelling at a mind-altering rate 7 times faster than light! On Earth, we have created some really fast objects. For instance, the speed of a bullet out of a gun can be as high as 4,200 kilometers per hour, which is three times the speed of sound. But it is not even the fastest thing. The fastest man-made object would be the NASA Parker Solar Probe spacecraft which reached a speed of 535,000 kilometers per hour using the Sun's gravity! Now, that is fast. But you would be surprised to know that it is just 0.05% of the speed of light (300,000 kilometers per second). So, you can imagine just how fast light really is. And till now, it was surmised that nothing can travel faster than light. Bu...
