Could the Universe Be Rotating? A New Theory Tackles the Hubble Tension

April Joy Jovita

The Hubble tension, a long-standing puzzle in cosmology, arises from conflicting measurements of the universe’s expansion rate. A groundbreaking study proposes that the universe may rotate once every 500 billion years, offering a potential solution to this cosmic conundrum. This theory challenges conventional models and opens new avenues for understanding The Hubble Tension Explained The ...

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 ...
