Hidden Mantle Layers : New Studies According to two new studies, the mantle, a layer of solid rock sandwiched between the Earth’s upper crust and lower core, has been hiding two new layers. The first layer is a low viscosity zone in the upper mantle, approximately 100 kilometres thick, which was discovered by studying deep […]

JO201 : Jellyfish Galaxy The Hubble Space Telescope recently captured an image of JO201, a jellyfish galaxy in the Abell 85 galaxy cluster. JO201 is a jellyfish galaxy which lies in Abell 85 galaxy cluster. It is at a distance of about 700 million lightyears, in the constellation of Cetus or the Whale. Jellyfish galaxies […]
Radio Galaxies : Discovery
Radio Galaxies : Discovery A team of astronomers from the National Centre of Radio Astrophysics (NCRA) Tata Institute of Fundamental Research (TIFR) Pune; Physical Research Laboratory (PRL) Ahmedabad; and the University of Oxford recently discovered several ‘elusive dying radio galaxies’. Radio Galaxies, also known as radio-luminous galaxies or radio-loud galaxies, are a particular type of […]
Fifth Inner Core Layer Of The Earth
Fifth Inner Core Layer Of The Earth: The recent frequent earthquakes have helped scientists discover a new core. This fifth inner core is a solid ball of nickel and iron and is the innermost layer. So far scientists believed that there are only four layers in the earth. They are the outermost layer called the […]
6 Monster Galaxies Discovered
6 Monster Galaxies Discovered: The James Webb Space Telescope (JWST) has discovered six Monster galaxies, formed roughly 500-700 million years after the Big Bang, according to a Study. Researchers spotted the six monster galaxies using the Cosmic Evolution Early 44 Release Science programme of JWST. The programme studies the formation of the earliest galaxies when […]

Underwater Noise Emissions
Underwater Noise Emissions: According to a News Study, “Measuring Underwater Noise Levels Radiated by Ships in Indian Waters”, the rising Underwater Noise Emissions (UNE) from ships in the Indian waters are posing a threat to the Marine Ecosystem. The measurement of the ambient noise levels was carried out by deploying a hydrophone autonomous system around […]
Mammatus Clouds : Picture Released By NASA
Mammatus Clouds : Picture Released By NASA NASA released a Picture of the day which was Mammatus Clouds. Mammatus is a cellular pattern of pouches hanging underneath the base of a cloud, typically a cumulonimbus raincloud, although they may be attached to other classes of parent clouds. Mammatus may appear as smooth, ragged or lumpy […]
