First Black Hole Image Sparks 3000-Light-Year Jet Cosmos
The First Image of a Black Hole and a New Frontier in Astrophysics In a historic achievement, the Event Horizon Telescope (EHT) captured the first-ever image of a black hole—M87*—and now scientists have traced a vast, 3,000-light-year-long jet back to its enigmatic origin. This breakthrough connects the glowing shadow at the heart of a distant…

James Webb Space Telescope Reveals Rapid Growth in Early Galaxies: Cosmic Adolescence Explained
Overview: A New View of the Early Universe In a striking new set of observations, the James Webb Space Telescope (JWST), alongside the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA), provides our most detailed look yet at the youngest galaxies in the cosmos. The findings show that these early galaxies—formed just a…

Black Hole Volcano Erupts: A 100 Million-Year Nap Ends in a Cosmic Firework
Introduction: A Dormant Giant Returns In a striking turn of cosmic events, astronomers report that a supermassive black hole nestled in a distant galaxy cluster has reawakened after nearly 100 million years of quiet. Described by researchers as a dramatic eruption akin to a ‘volcano’ waking from a deep sleep, the event offers a rare…

Hidden companion around Betelgeuse revealed by Hubble’s light wake
Hubble’s wake reveals a hidden companion around Betelgeuse Astronomers have long been fascinated by Betelgeuse, the red supergiant that anchors Orion’s familiar winter sky. While its bright red glow makes it one of the best-studied stars in the galaxy, new Hubble Space Telescope observations hint that Betelgeuse may have a hidden companion star stirring its…

White Dwarf Binary: First Look at the Inner Region
A New View into a Dead-Star Dance About 200 light-years from Earth, a binary pairing hides in plain sight: a white dwarf—the dense remnant of a once-sunlike star—and its larger stellar companion. Recent observations provide the first close look at the innermost region where their gravitational and magnetic forces shape a cosmic waltz of matter.…
