Unfairly dismissed as a flop on release, 'Waterworld' is a spectacular example of the '90s action genre. If only they didn't give him gills…

The BOAT is the ruler of all gamma-ray bursts, releasing as much energy in seconds as the sun will in 10 billion years — and it could be revealing the secrets of these extreme cosmic blasts.

Living in space changes the human body — but arteries seem particularly resilient to microgravity's effects.

A controversial new paper questions whether the interstellar object 3I/ATLAS is a potentially dangerous alien probe, similar to claims made about 'Oumuamua. But experts have called it "nonsense".

Microwave satellite data that are key to capturing changes in a hurricane’s strength will not be taken from meteorologists as originally planned

The Trump administration is releasing its proposal to undo the “endangerment finding,” the long-standing rationale and legal imperative for regulating greenhouse gases under the Clean Air Act

Decades ago, a renegade physicist suggested that gravity isn't so much a force as just a byproduct of the universe's tendency to get more disordered. Now this idea might finally be testable

An aircraft body modeled after an air taxi with weighted test dummies inside is being prepared for a drop test by researchers at NASA’s Langley Research Center in Hampton, Virginia. The test was completed June 26 at Langley’s Landing and Impact Research Facility. The aircraft was dropped from a tall steel structure, known as a gantry, after being hoisted about 35 feet in the air by cables. NASA researchers are investigating aircraft materials that best absorb impact forces in a crash.

While all the technology of the Apollo program still exists in the form of blueprints and designs, all the human expertise that went into crafting those rockets and spaceships is now either retired or passed away.

The JunoCam on NASA's Juno spacecraft has given us fantastic images of Jupiter and its moons, especially volcanic Io. But the instrument is suffering after years of exposure to Jupiter's intense radiation. There are few options for repairing that damage from such a great distance, but it looks like NASA's done it.
