A “kilonova”—the merging of two neutron stars accompanied by intense gamma-ray bursts—was discovered by astronomers in 2017. Three and a half years after the kilonova explosion, astrophysicists have found unusual X-rays they believe might be the first evidence of a kilonova “afterglow.” This might have been a first detection of stuff going into a newly created black hole, according to astrophysicists. Laser interferometry is used by LIGO to detect gravitational
The new common name for Lymantria dispar, now known as spongy moth, has been welcomed by scientists. However, they are still working to stop the spread of the invasive bug. Leaf-eating moths may cause substantial damage or even death to a wide range of plants and shrubs.
