New Study Uncovers Shadowy Origins of Universe’s Most Luminous Phenomena

New Study Uncovers Shadowy Origins of Universe’s Most Luminous Phenomena

Published by Webster

Some of the brightest lights in the universe shine from some of its darkest corners — so-called supermassive black holes. Invisible to the human eye, these high-energy powerhouses light up the cosmos with emissions that are detected by space telescopes. Thousands of such light sources have been discovered with NASA’s Fermi Gamma-ray Space Telescope, which has been observing since 2008. These aren’t just stars — they are active galactic nuclei (AGN) where large gravitational forces fling matter around black holes, creating intense radiation blasts all across the electromagnetic spectrum. Blazars and AGN Jets Reveal How Black Holes Shape and Light Up the Universe As per NASA’s report ,observational data, black holes lurk at the centres of most galaxies and are hundreds of thousands to billions of times the mass of the sun. In AGN, gas and dust fall into an inward-spiralling disk. Second, the disks experience friction and magnetic forces that produce light from radio to gamma rays. About one in ten AGN produce powerful jets of particles that move at nearly the speed of light, and it’s still a mystery …

Rare Sea Smoke and Streaming Snow Phenomena Captured Near Pine Island Glacier

Rare Sea Smoke and Streaming Snow Phenomena Captured Near Pine Island Glacier

Published by Webster

In October 2024, Pine Island Glacier, known for its fast-paced retreat and frequent iceberg calving, revealed more than its icy edge. This time, unusual atmospheric activity brought attention to the skies above Antarctica’s West Antarctic Ice Sheet. On October 10, the Operational Land Imager (OLI) on NASA’s Landsat 8 captured an exceptional image showing “sea smoke” and snow carried by powerful winds. These phenomena usually evade satellite images because clouds often block the view. However, this day was an exception, providing a rare look at near-surface atmospheric events, explained Christopher Shuman, a glaciologist from the University of Maryland, Baltimore County, based at NASA’s Goddard Space Flight Center. Sea Smoke at the Glacier’s Edge Sea smoke, in particular, emerged prominently near the glacier’s terminus and over open water at its northern boundary. This phenomenon arises due to the stark temperature contrast between the icy surface and surrounding waters. Strong winds pushed the sea ice and water away from the glacier, drawing relatively warmer water to the surface. When this warmer water meets the frigid air, it …

Large-scale climatic phenomena conducive for monsoon: IMD chief Mohapatra

Published by Webster

As summer scorches large parts of the country, weather scientists have picked up early signs of a favourable monsoon season this year in fading El Nino conditions and lesser snow cover over Eurasia. In an interview with PTI, India Meteorological Department Director General Mrutyunjay Mohapatra said large-scale climatic phenomena were conducive for the southwest monsoon, which is crucial for the largely rain-fed Indian economy. “This year El Nino is fading. By the beginning of June, it may become a neutral condition,” Mohapatra said, referring to the warming of the central Pacific Ocean which is considered one of the factors to impact the southwest monsoon. He said the second half of the July-September monsoon season may witness La Nina conditions, which refer to the cooling of the central Pacific Ocean. “La Nina is good for the Indian monsoon. And neutral conditions are good. However, El Nino is not good. In 60 per cent of years, El Nino has had a negative impact on the Indian monsoon, but last year, it did not have a negative impact,” …
