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.

If you've ever wanted to help find an exoplanet, this is your chance. There's a new open research initiative that invites participants to help identify exoplanets using simple visual pattern matching ...

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

Astronomers have long relied on two main methods to detect exoplanets—the transit method, which looks for dips in a star’s brightness when a planet passes in front of it, and the radial velocity ...

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 ...

The first confirmed exoplanets were discovered in 1992 orbiting a pulsar, followed by the first discovery around a sun-like star in 1995. Currently, nearly 5,500 exoplanets in over 4,000 systems have ...

Scientists using NASA's Transiting Exoplanet Survey Satellite (TESS) discovered an exoplanet, which NASA defines as “any planet beyond our solar system.” What's False However, the “strange signals” ...
