NASA Solves Black Hole Jet X-ray Mystery with IXPE’s Polarization Powers
- Friday May 9, 2025
- Written by Gadgets 360 Staff
NASA’s IXPE satellite may have solved a longstanding astrophysical mystery: how are X-rays produced in the extreme jets of supermassive black holes? By observing the blazar BL Lacertae, IXPE recorded low X-ray polarization versus very high optical polarization—confirming Compton scattering as the likely mechanism. This breakthrough supports the...

The Universe’s Brightest Lights Have Surprisingly Dark and Mysterious Origins
- Saturday May 3, 2025
- Written by Gadgets 360 Staff
NASA’s Fermi Gamma-ray Space Telescope has revealed that some of the universe’s brightest light sources originate near supermassive black holes in galaxy centres. These active galactic nuclei emit intense radiation, including gamma rays and X-rays, despite black holes themselves being invisible. Their powerful jets and high-energy emissions cha...

Analysis of Neutrino That Crashed Into Antarctica Sheds Light on Origin of Cosmic Rays
- Friday July 15, 2022
- Edited by Gadgets 360 Newsdesk
In a new study, published in Science, researchers have detected a cosmic ray offshoot called a neutrino or ghost particles. These parties are considered so evasive that they interact with anything but as they travel, they don't come in contact with the atoms. Neutrinos are like small particles messengers that have spawned a new field of astronomy c...

NASA Probe Spots Hints of Gamma-Ray Cycle in 'Active' Galaxy
- Sunday November 15, 2015
- World News | Indo-Asian News Service
Astronomers using data from NASA's Fermi Gamma-ray Space Telescope have detected hints of periodic changes in the brightness of a so-called "active" galaxy, whose emissions are powered by a supersized black hole.
