The University of Arizona-led OSIRIS-REx mission made contact with the asteroid Bennu for about 4.7 seconds ... just long enough to gather small particles of dust and rock stirred up by a blast ...

After leaving Earth, Tianwen-2 will reach Kamo‘oalewa by July 2026. This tiny, elongated asteroid likely spans no more than ...

If Bennu hit Earth, Dr Dai and his co-authors estimate that 100 to 400 million tonnes of dust would linger above Earth for around two years. Those dust particles would act like a vast planet-wide ...

President Donald Trump’s fiscal 2026 budget request, if approved by Congress, would kill many of NASA’s plans for robotic ...

The researchers report in Physical Review Letters that dark matter could have formed in the early life of the universe from the collision of high-energy massless particles that lost their zip and ...

But such measurements are notoriously challenging: the instruments used are themselves governed by quantum laws, and their interaction with particles can alter the very properties they are meant ...

Recently, a team of scientists and engineers at Rice University discovered a similar phenomenon on a microscopic scale, where tiny magnetic particles driven by rotating fields spontaneously move ...

Their mathematical models show that dark matter could have formed in the early universe from the collision of massless particles that lost their energy and condensed -- like steam turning into ...

In a study appearing today in the journal Advanced Materials, the researchers showed that they could use these particles to deliver two doses of diphtheria vaccine -- one released immediately ...

Nearly two years after launch, the University of Arizona-led OSIRIS-REx mission caught its first glimpse of the asteroid Bennu on Aug. 17 from 1.4 million miles away. The asteroid appeared as a ...

Now, a new study in the journal Environmental Science and Technology says it's possible that humans may be consuming anywhere from 39,000 to 52,000 microplastic particles a year. With added ...
