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.

Exoplanets are often discovered using the transit method (more than three-quarters of those discovered have been found this way.) The same transit technique can be used to study them, often revealing ...

On Jan. 11, 2026, I watched anxiously at the tightly controlled Vandenberg Space Force Base in California as an awe-inspiring ...

To date, over 5,500 exoplanets — planets that orbit stars other than the sun — have been discovered, and a large portion of those alien worlds have been observed via something called "the transit ...

What planet is most like Earth? Reseachers have identified several exoplanets similar to our planet, but none that are an ...

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 ...

The measured transit spectrum (top) and eclipse spectrum (bottom) of WASP-80 b from NIRCam’s slitless spectroscopy mode on NASA’s James Webb Space Telescope. In both spectra, there is clear evidence ...
