NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution of these elements throughout the young solar...

Interstellar object 3I/ATLAS reveals no technosignatures in seven-hour radio scan

by quasarn01 | Jun 3, 2026 | Astronomy

Scientists at the SETI Institute recently searched for technological signals from 3I/ATLAS, the third interstellar object observed in our solar system. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory in Northern California, the team scanned a...

Temperature gaps help sneeze clouds stay denser and travel farther, experiments show

by quasarn01 | Jun 3, 2026 | Latest in Physics

When a person coughs or sneezes, they expel a cloud of microscopic particles capable of carrying viruses and bacteria that act as vectors for respiratory diseases such as flu, COVID-19 or tuberculosis. Understanding how these aerosols disperse in the air is crucial...

Water-wave tweezers steer tiny ‘surfers’ without touching them

by quasarn01 | Jun 3, 2026 | Latest in Physics

Summer brings with it the sight of surfers moving seamlessly across wave crests, with ocean waters carrying them along coastlines. A team of scientists has now created a similar phenomenon—with small objects rather than surfers—that can be controlled by humans rather...

We can predict space weather—what if we could also stop it?

by quasarn01 | Jun 3, 2026 | Astronomy

The weather on Earth can get pretty messy sometimes. But in space, it can be wild, and the effects can be far-reaching. Solar flares, giant explosions on the sun, can send out streams of energy that block radio communications and fry satellite electronics. Geomagnetic...
