Astronomers study planetary transits and atmospheric signals using interstellar object 3I/ATLAS, drawing on transit spectroscopy principles and recent observational constraints discussed by Avi Loeb.

Humanity has long wondered if we are being watched from the stars, but the answer might lie in our own exhaust fumes. As the ...

An upcoming astronomical event will provide a rare opportunity for amateurs to observe a technique scientists are using to search for planets around stars. On May 7, Mercury will pass in front of the ...

The Mercury transit will take place from 11:12 a.m. – 4:10 p.m. PST (2:12 p.m. – 7:10 p.m. EST). Portions of event will be visible from the Pacific, the Americas, eastern Asia, Australia, and New ...

For all our technological progress, humanity remains confined to a single planet. But that may not always be the case. Over the past few decades, astronomers have discovered thousands of exoplanets, ...

Universe Today reports on a new telescope proposal that could help astronomers detect Earth-sized exomoons, explaining current limits, future technology, and why moons around distant planets matter ...

So far, humanity has yet to find its first "exomoon"—a moon orbiting a planet outside of the solar system. But that hasn't ...
