researchers may have found the first direct evidence of ancient black holes, which could revolutionize our understanding of dark matter. A gravitational wave, captured by LIGO in November 2025proposed a revolutionary hypothesis: the collision that produced the signal may not have involved ordinary black holes in stars, but rather black holes formed in the early … Read more
When our powerful infrared telescopes allowed astronomers to look further into the future, they made some amazing discoveries. One of them involves supermassive black holes (SMBH), the physics-defying behemoths at the center of massive galaxies such as the Milky Way. In fact, the SMBH grew much faster in the jewelry world than it does in … Read more
The latest update to LIGO’s catalog has doubled the number of confirmed gravitational waves – waves in spacetime caused by catastrophic events. And now, astronomers come to the dire decision of selecting an updated dataset. In a Nature paper published today, researchers have confirmed the first evidence of two unstable supernovae, doing so with gravitational … Read more
The early universe is so far outside our understanding of how the world works that it is difficult to describe in words. At that time, the universe was not filled with stars and galaxies but with a boiling soup of quarks and gluons, with several black holes that were thrown, sometimes exploding like depth charges. … Read more
When spring comes around, we’re not the only ones who are wandering around after a long winter. The New Jersey Department of Environmental Protection (NJDEP) has issued an alert to remind residents that black bears are coming out of their dens and will be looking for food. Read it in Spanish here. Officials said it’s … Read more
a black hole: A region of space with such a strong magnetic field that nothing or radiation (including light) can escape. cancer: Any of more than 100 different diseases, each characterized by rapid, uncontrolled growth of abnormal cells. The progression and growth of cancer, also known as malignancies, can lead to swelling, pain and death. … Read more
It is not often that astronomers can see large changes in the brightness of a galaxy within a few years. Most galaxies change in brightness (and other properties) over millions or billions of years. So, when images of the distant 10-billion-light-year galaxy J0218-0036 showed that it dimmed to a twentieth of its previous brightness in … Read more
Primordial black holes (PBHs) are a very special type of black hole, thought to have formed from dense pockets of subatomic matter in the seconds after the Big Bang – and a new study reports what may be the first direct time. That may take years to prove, but the prospect is exciting. Black holes … Read more
James Webb Telescope (JWST) discovered small galaxies with black holes that are not well understood. These black holes, located in galaxies with masses much smaller than those traditionally associated with supermassive black holes (SMBHs), challenge long-held beliefs about how galaxies and their central black holes evolve. The discovery of these “extreme” black holes pushes the … Read more
In 1916, just a year after Albert Einstein published his general theory of relativity, Karl Schwarzschild used mathematical calculations to show this: If enough mass were packed into a very small volume, then this dense enough mass would create a region where the gravitational force is so strong that nothing, including light, could escape from … Read more
