Black Holes Could Be Gateways, Not Dead Ends, According to New Theories

Suhail Ahmed

  For decades, black holes have been cast as the ultimate full stop of the universe: regions where gravity wins, light loses, and everything ends in silence. Now, a new set of theories is rewriting that script, suggesting black holes might be less like cosmic trash compactors and more like tunnels or gateways that reshape ...

The ominous Chamaeleon I dark cloud, the nearest star-forming region to Earth, is captured in this image taken with the 570-megapixel Department of Energy-fabricated Dark Energy Camera mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab. Chamaeleon I is one portion of the larger Chamaeleon Complex and is home to three reflection nebulae that are brightly illuminated by nearby newly formed stars.

Chamaeleon I: Where New Stars Light Up Cosmic Darkness

Jan Otte

Behind clouds of interstellar dust, a cosmic drama is playing out deep in the southern constellation of Chamaeleon. The Chamaeleon I dark cloud is one of the closest places to Earth where stars are born. It is only 550 light-years away. In this “stellar nursery,” newborn stars break through the darkness and light up huge ...

A Universe on Purpose? The Physics That Made Life Possible

Jan Otte

The universe shouldn’t exist at least, not in a form that allows life. Yet here we are, thinking, questioning, and marveling at the cosmos. The fundamental laws of physics appear fine-tuned with eerie precision. Alter any one of nature’s constant gravity, the speed of light, the mass of an electron even slightly, and stars wouldn’t ...
