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.

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 ...

WASHINGTON (Reuters) -In addition to providing a trove of information about the early universe, the James Webb Space Telescope since its 2021 launch has obtained valuable data on various already-known ...

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 ...

Not so long ago, we lived in a universe with only a small number of known planets, all of them orbiting our Sun. But a new raft of discoveries marks a scientific high point: More than 5,000 planets ...
