North Polar Spur
The North Polar Spur is a large ridge of hot radio and X-ray emitting gas. This ridge of gas rises above the plane of the galaxy. About North...
LHAASO
The Large High Altitude Air Shower Observatory (LHAASO) is a gamma-ray and cosmic-ray observatory in Sichuan Province of China. Set at an altitude of 4,410 metres above the...
Black hole winds
Black hole winds are winds bearing dust and gas that are ejected from the accretion disc of black holes. Accretion disc is a disc of swirling material that... J0437+2456 blackhole
J0437+2456 blackhole is a supermassive blackhole inside the Galaxy J0437+2456 which is 228 million light years away from the Earth. It is the 1st known wandering supermassive blackhole....
Core accretion model
Core accretion model is one of the 2 theories that explain the formation of giant gas planets. The other theory is disk instability model. In core accretion model,...
Radiocaesium
Radiocaesium or radioactive caesium (Cs-137) is a radioactive isotope of the element caesium. It is a common product of the fission reaction of uranium-235 in nuclear reactors. In...
Hawking Radiation
Hawking radiation was first theorised by Stephen Hawking in 1974. According to the hypothesis, black holes are not pitch-black star swallowers. Rather, they emit light due to photon...
Space hurricane
Space hurricane is swirling mass of plasma that rain electrons instead of water into the ionosphere. It may have been created by a large and rapid transfer of...
Oort cloud
Oort cloud, made of icy, comet-like objects, surrounds the Sun, planets and Kuiper Belt objects. According to a new theory by Harvard University scientists, it may be the...
Neutrino oscillations
Neutrino oscillation is a phenomenon in which neutrinos change from one ‘flavour’ to another during the supernova process. There are 3 flavours or types of neutrinos- electron-neutrino, muon-neutrino...
Core collapse supernova
Core collapse supernova or type II supernova is the explosion of a star accompanied by the collapse of its inner material. This occurs in stars that are over...
