Earth and Mountains

There are many mountains in the world, and they are found on every continent. Mountain ranges such as the Himalayas, the Andes, the Rockies, the Alps, and the Himalayas comprise numerous peaks and valleys. Additionally, new mountains can be formed through geological processes like tectonic activity, and erosion can also change landscapes over time. The exact number of mountains can vary based on definitions and classifications, but it is understood that there are countless individual mountains worldwide.  Mountains play a significant role in shaping the Earth's surface and influencing its geological and environmental processes, but they don’t directly "keep" the Earth in a specific form. Here are a few ways mountains contribute to the Earth's landscape: 1. Tectonic Activity: Mountains are often  While mountains are crucial to the Earth's geological and biological systems, the Earth's "form" is determined by a combination of various factor...

Astronomers describe a violent black hole outburst that provides new insight into galaxy cluster evolution

Billions of years ago, in the center of a galaxy cluster far, far away (15 billion light-years, to be exact), a black hole spewed out jets of plasma. As the plasma rushed out of the black hole, it pushed away material, creating two large cavities 180 degrees from each other. In the same way you can calculate the energy of an asteroid impact by the size of its crater, Michael Calzadilla, a graduate student at the MIT Kavli Institute for Astrophysics and Space Research (MKI), used the size of these cavities to figure out the power of the black hole's outburst.
