Neutral summary of 3I/ATLAS anomalies, detailing unusual trajectory, mass, jets, gas composition, and non-gravitational ...

You see this all the time in textbooks: This is often described as "the acceleration due to gravity". Is this really the best thing to call this? No. A better name would be "the local gravitational ...

The Qatar General Organization for Standards and Metrology (QGOSM) announced the completion of the first measurement of absolute ...

One of the most astonishing facts about science is how universally applicable the laws of nature are. Every particle obeys the same rules, experiences the same forces, and sees the same fundamental ...

Researchers have found a significant new relationship in spiral and irregular galaxies: the acceleration observed in rotation curves tightly correlates with the gravitational acceleration expected ...

An illustration of an accelerating space rocket in Tom Siegfried’s essay “Getting a grip on gravity” (SN: 10/17/15, p. 16), explained that a clock at the top of the ship would tick faster than one at ...

Hubble images of interstellar object 3I/ATLAS reveal a sunward anti-tail, showing a teardrop-shaped coma with separated ...

In a recent study published in Scientific Reports, researchers explored how nutrition knowledge, physical strength and activity, and body composition are related to whether Air Force cadets lose ...
