A decade-long NIST experiment has produced a new measurement of the universal gravitational constant that differs unexpectedly from another leading result, deepening a 225-year-old physics puzzle. The discrepancy is tiny, but for one of nature’s most…

A giant crater may reveal the origin of Mars’ doomed moon

https://www.sciencedaily.com/releases/2026/09/260919031040.htm

Published: September 19, 2026 08:12

A massive crater on Mars’ moon Phobos may hide a dense region of compressed material that could reveal whether the moon is a captured asteroid or debris from an ancient impact on Mars. Japan’s upcoming MMX sample return mission could provide the…

NASA’s Roman Space Telescope could last more than twice as long as planned

Published: September 18, 2026 07:31

NASA’s Roman Space Telescope may now have enough fuel for at least 22 years of science, more than double its original 10 year design life. An extremely precise course correction, extra fuel at launch, and additional expected savings could keep the powerful…

Scientists are about to test Einstein’s gravity with exotic matter

https://www.sciencedaily.com/releases/2026/09/260918024808.htm

Scientists have found a new way to create a controlled beam of muonium, an exotic atom containing a heavier cousin of the electron. The advance could allow researchers to test for the first time whether gravity acts on second-generation particles exactly…

NASA’s Moon orbiter finds a 728-foot crater that wasn’t there before

NASA’s Lunar Reconnaissance Orbiter has revealed a 728-foot-wide crater that formed on the Moon in 2024, making it the largest newly formed crater ever identified in the solar system. The impact disturbed the surface for miles around it, creating a…

A $100 detector can see invisible particles raining down from space

https://www.sciencedaily.com/releases/2026/09/260917003725.htm

A pocket-sized, roughly $100 detector can reveal the invisible stream of cosmic particles constantly passing through Earth and even through our bodies. What began as a student physics project is now being used in major experiments, balloon missions, and…

Astronomers just found the youngest known planet ever

https://www.sciencedaily.com/releases/2026/09/260917003712.htm

Astronomers have confirmed a Jupiter-size planet less than a million years old, making Elias 2-24 b the youngest known planet and giving scientists a rare look at a world still being born. Its surprisingly rapid formation challenges leading theories about…

JWST’s mysterious little red dots may be black holes growing at incredible speeds

https://www.sciencedaily.com/releases/2026/09/260917003703.htm

Published: September 17, 2026 08:45

New supercomputer simulations suggest JWST’s puzzling Little Red Dots are rapidly growing black holes from the early Universe. Extreme radiation may have helped create unusually massive black hole seeds, while dense surrounding gas allowed them to grow…

NASA’s New Horizons spots signs of liquid nitrogen flowing on Pluto

https://www.sciencedaily.com/releases/2026/09/260916232525.htm

Published: September 17, 2026 00:02

Scientists have found the first evidence that liquid may have flowed across Pluto’s surface in the recent past. Dark features on the enormous Sputnik Planitia glacier appear consistent with liquid nitrogen rising through cracks from deep beneath the ice.…

Venus may have swallowed its own moon
