Galaxy (adopted from Greek word ‘galactos’ meaning milk) is a complex structure of a gargantuan collection of dust, gas, billions of stars and their stellar systems, compact objects and dark matter which is held by gravity. Galaxies are the charms of the universe forming into groups, clusters and huge structures called superclusters, appear as filaments neighbouring large void regions!
Sagittarius A* is the nearest supermassive black hole to the sun and provides a reasonable opportunity to find out how the mystifying giant works. the black holes in other galaxies are exceptionally dynamic with a large amount of matter falling into it in the process of feeding, the one in the Milky Way is relatively quiet in nature.
Paleomagnetism is the study of the Earth’s past magnetic fields present in rocks and fine sediments like an actual record that can be enjoyed when played on the reverse.
The Indian Space Research Organisation, India has called off the launch of its one of the most ambitious project Chandrayaan 2 due to some technical snag.
Moon mineralogy mapper, which is also known as M3 was one of the most successful payloads from Chandrayaan-1. M3 from the Brown University and JPL was an imaging spectrometer designed to map the surface mineral composition. It confirmed the traces of water vapour, which was a significant contribution of the Chandrayaan-1 mission.
The primary objective of the Chandrayaan-2 mission is to find water on the lunar surface, which is backed by ‘the thousands of tests’ conducted by the agency. Landing the Chandrayaan-2 will be one of the major concern of the space agency, ISRO. The mission carries 13 Indian scientific instruments for conducting experiments
