What is GN-z11 and why is it important? Gazing billions of light-years across the vast cosmic expanse, astronomers have encountered a celestial enigma: GN-z11. This exceptionally luminous galaxy stands as one of the brightest and most distant ever observed, existing a mere 430 million years after the Big Bang (roughly 3% of the universe’s current […]
The universe is a vast and mysterious expanse, filled with celestial wonders that continue to captivate the human imagination. Among these enigmatic phenomena, one of the most intriguing is the concept of Gravastars. In this article, we will delve into the fascinating world of Gravastars, exploring their theoretical foundations, distinguishing features, and the implications they […]
The Einstein Probe, a cutting-edge space observatory, is set to embark on a groundbreaking mission that promises to unravel the mysteries of extreme black holes and star explosions. Central to this mission is the remarkable Lobster Eye technology, a revolutionary X-ray imaging system that enables the probe to capture high-resolution images of celestial phenomena. In […]
As astronomers ventured into the depths of a hungry black hole, their gaze unveiled a remarkable sight—a fierce surge of X-rays erupting from it, boasting a temperature a staggering 60,000 times hotter than the surface of our very own sun. What are Quasars? Are They Hungry Black Hole? Quasars are black holes that emit dazzling, […]
Astronomers using NASA’s Hubble Space Telescope have discovered what they believe to be some of the greatest evidence yet for the presence of a rare type of intermediate-sized black hole lurking in the heart of the nearest globular star cluster to Earth, about 6,000 light-years distant. What are the formation, distribution, and rarity of intermediate-mass […]
Astronomers have discovered a giant black hole at the center of Messier 84 “M84” (a massive elliptical galaxy). This giant black hole is leaving an “H”-shaped structure in the multimillion-degree gas around it. Using NASA’s Chandra X-ray Observatory, researchers mapped the hot gas in and around M84. This reveals the letter “H” formed by cavities […]
Bright galaxy Centaurus A (Cen A) stands out prominently in this composite image from several different telescopes. A supermassive black hole consumes matter from the surrounding gas and dust and shoots out enormous jets of high-energy particles and other matter. About 13,000 light-years away from the black hole is where the jet shown in the […]
It has taken decades of research for scientists to even begin to understand where Mysterious dark energy comes from. The rapid expansion of the cosmos suggests that some force is overpowering gravity, which should slow things down. Even though dark energy has been proposed as the source of that power, its origin has remained a […]
Using the Event Horizon Telescope, astronomers have captured an image of a quasar (bright structure at the galaxies’ cores) at the Centre of a faraway galaxy that emits vast amounts of light fueled by a feeding supermassive black hole. Such stunning phenomena, which can generate more energy than all the stars in their parent galaxy […]
In the heart of huge galaxies like our own, you’ll find a supermassive black hole (SMBH). They maintain their commanding position in the center of the galaxy, where they consume gas, dust, stars, and everything else that comes too close, causing them to become ever more massive over time. However, in extremely unusual cases, an […]
