In the vast universe, stars meet their end in grand explosions, scattering elements like carbon and iron. These events, known as supernovae, are well-known. But there's another type of explosion, called a kilonova, which happens when two dense, dead stars, or neutron stars, collide. This collision c
Scientists have made an exciting discovery in the world of black holes. They found two pairs of these cosmic giants crashing into each other. What makes this special is that the bigger black hole in each pair might have been around for a while, having already collided with another black hole before.
Black holes colliding is not just a sci-fi spectacle; it's a real cosmic event that sends out ripples in space and time, called gravitational waves. These waves, first spotted in 2015, carry energy and can teach us a lot about gravity, the force that keeps us grounded. Gravity, as Einstein explaine
Neutron stars are the remnants of massive stars that have gone supernova. These dense, compact objects are fascinating because they can emit both gravitational waves and gamma rays. This double act of signals is a big deal for scientists. In 2017, two detectors, Fermi-GBM and INTEGRAL SPI-ACS, pick
China's space program is on the cusp of a major milestone, as the country prepares to unveil a long-term vision for space science. This ambitious plan aims to accelerate China's progress in the field, solidifying its role as a global leader in space exploration. The Chinese Academy of Sciences has o
