ALMA stands for Atacama Large Millimetre/Submillimetre Array. Operational since 2013, it is the world’s most powerful telescope with 66 high precision antennas and is ten times sharper than Hubble. It is built in the Atacama Desert in Chile at an altitude of 16,500ft with almost no humidity or vegetation to block its view of the…
Uranus, the third largest planet, was discovered on 13 March 1781 by Sir Frederick William Herschel. Herschel also discovered the infrared radiation.
The James Webb Space telescope is a space telescope scheduled to be launched this decade. It has been designed to study the first formed galaxies. It would be able to see objects lying up to 1.5×106 km away from the earth. A sun shield will protect the telescope from the heat of the sun. (It…
Nicolaus Copernicus died immediately after the publication of his book De Revolutionibus Orbium Coelestium (On the Revolutions of the Celestial Spheres).

A neutron star is a remnant of a star after it has collapsed due to its own gravity. These stars are composed of subatomic particles called neutrons without any electrical charge. These stars could be two times the mass of the sun. The neutron stars have a very high surface gravity which could be 2…
The researchers at the California Institute of Technology say that an ancient delta was found on Mars. Using high-resolution images of a spanning 100 square kilometre area from the Mars Reconnaissance Orbiter (MRO), the researchers discovered the fan-shaped inverted channels that appeared to be emptying into an ancient ocean. The inverted channels appeared as ridges…
