The universe is a truly massive place, filled with wonders that can sometimes sound a little bit scary. One of the most talked-about and mysterious objects in all of space is the black hole. For a long time, these were mostly a theoretical idea, something that came purely from deep scientific math. Now, we know … Read more
An Active Galactic Nucleus (AGN) is the term scientists use for the extremely bright, energetic center of some galaxies. It is essentially a supermassive black hole that is actively “eating.” When gas, dust, and even whole stars get too close to the black hole, they don’t just fall straight in. Instead, they spiral around it … Read more
We have all heard about black holes. They are one of the most famous and scary objects in space. A black hole is a place in space where gravity is so strong that it pulls everything in. Nothing, not even light, can escape once it gets too close. They are like a one-way street in … Read more
The universe we live in is a huge, expanding place, and scientists have been trying to figure out its ultimate fate for decades. Will it shrink back down? Will it just fade away slowly? For the longest time, the most likely end seemed to be the “Big Freeze,” where everything gets too far apart, cold, … Read more
Black holes are some of the most fascinating objects in the entire universe. In simple terms, a black hole is a place in space where gravity is so strong that nothing, not even light, can escape once it gets too close. This intense gravity comes from a huge amount of matter being squeezed into an … Read more
When we think of outer space, the first thing that often comes to mind is silence. For the most part, that is correct. Sound, as we know it, is a vibration that needs something to travel through, like air or water. The vast emptiness of space is a vacuum, which means there is no air … Read more
Space is full of incredible, powerful objects that challenge what we think we know about physics and reality. Among these wonders are black holes, which are regions of spacetime where gravity is so strong that nothing, not even light, can escape. We know our own Milky Way galaxy has a supermassive black hole, Sagittarius A* … Read more
We often think of black holes as the unmovable centers of galaxies. Most large galaxies, including our own Milky Way, have a giant “supermassive” black hole sitting right at their core. This object acts like a gravitational anchor, holding the galaxy’s center together. These black holes are millions or even billions of times heavier than … Read more
Spaghettification is caused by something called a gravitational gradient, and it is the key to understanding this whole topic. A gradient is simply a difference in a measurement from one point to another. In this case, it is the difference in the strength of gravity pulling on two separate parts of the same object, like … Read more
Our universe is a vast and busy place, full of giant galaxies, burning stars, and deep mysteries. Scientists are like detectives, using powerful telescopes to look for clues about how it all works. Recently, they spotted an event that is incredibly violent and fascinating. Far away in a distant galaxy, a black hole was caught … Read more
