Astronomers explain one of the strangest explosions ever seen in our universe  The Washington Post AI helps astronomers make a potentially major find — an exploding star being attacked by a black hole  Space Megastars shredded by black holes offer new type of cosmic explosion  Science News Explores Star Trying to Swallow a Black Hole May Have Triggered a New Type of Supernova  ScienceAlert …

A recent breakthrough in astronomical research, published in Nature Astronomy, has provided a detailed glimpse into the internal structure of an ancient galaxy, thanks to one of the strongest gravitational lensing events ever observed. The study, led by Seiji Fujimoto, reveals how natural magnification through gravitational lensing allows scientists to study distant galaxies with unprecedented clarity. The research, which combines …

IN A NUTSHELL 🔭 The James Webb Space Telescope discovers over a dozen dormant galaxies in the early universe. 🌀 Supermassive black holes and neighboring galaxies likely halt star formation by depleting or heating cold gas. 🌟 The stop-and-go pattern of star formation is supported by the discovery of 14 galaxies with varying masses. 🔍 Future JWST programs aim to …

A recent discovery sheds light on a bizarre phenomenon at the center of our Milky Way: the detection of cold hydrogen clouds embedded within the superheated Fermi bubbles, vast structures of gas and cosmic rays that have been towering over the galactic center for millions of years. The unexpected nature of these clouds suggests a much more recent and violent …

The Cosmic Horseshoe gravitational lens: The newly discovered ultramassive blackhole lies at the centre of the orange galaxy. Far behind it is a blue galaxy that is being warped into the horseshoe shaped ring by distortions in spacetime created by the immense mass of the foreground orange galaxy.

A distant galaxy appears to have more than a dozen tightly packed star-forming clumps arranged like a bunch of grapes — far more than astronomers thought possible in a galaxy from the early universe. The galaxy, nicknamed “Cosmic Grapes,” is believed to have formed just 930 million years after the Big Bang. A new study has revealed that the galaxy …

Astronomers have discovered a giant planet named TOI-6894b orbiting a very small red dwarf star that has only one-fifth the mass of the Sun. Despite the star’s small size and low brightness, TOI-6894b is larger than Saturn but has only half its mass. This surprising discovery challenges previous ideas that such tiny stars cannot form or hold large gas planets. …

Outdoor lighting for buildings, roads and advertising can help people see in the dark of night, but many astronomers are growing increasingly concerned that these lights could be blinding us to the rest of the universe. An estimate from 2023 …
