James Webb Space Telescope Reveals Oldest Known Galaxy

A formation of radio waves looks remarkably like a treble clef in this Oct. 14, 2026, image from NASA’s Chandra X-Ray Observatory. Researchers used Chandra to find that the Treble Clef is likely caused by an outburst from a supermassive black hole, followed by a collision of two galaxy clusters. Rea

Fly through the cosmos to the star-forming region NGC 7129. This video showcases the incredible power of the James Webb Space Telescope to see through dust and gas, unveiling the intricate and colorful details of where stars are born.

Astronomers have used NASA’s Chandra X-ray Observatory to break down the cause of a remarkable formation of radio waves they have nicknamed the “Treble Clef” because its distinct shape strongly resembles the musical symbol. The researchers discovered the Treble Clef is likely caused by an outburst f

If you’ve ever had your car start sluggishly, or not at all, on a particularly frigid winter morning, you know standard batteries do not like extreme cold. That’s why NASA researchers are working to develop a battery that could function in the brutal cold of the Moon’s South Pole, where nighttime te

What if the Moon never existed? It's not just darkness — without the Moon, Earth's tides freeze, our axis wobbles, and seasons collapse. The Moon is the anchor of our world. In this 35-second documentary short from Beyond What If, we explore the real physics behind one of the most mind-bending "what

"Two massive stars in Wolf-Rayet 140 swing past one another, their winds collide, material compresses, and carbon-rich dust forms," according to NASA. Time-lapsed James Webb Space Telescope imagery of the system has revealed that every shell is racing away from the stars at almost 1% the speed of li
