SETI combines cutting-edge radio astronomy, data science, and planetary research in a global effort to detect signs of ...

An international team of astronomers reports the discovery of two new exoplanets, a few times more massive than Earth, ...

But on April 17, a study was published revealing that a team of astronomers using the James Webb Space Telescope (JWST), led by Nikku Madhusudhan, had discovered gases on an exoplanet called K2 ...

"The signal came through strong and clear." Based on its size and other characteristics, astronomers suspect that K2-18b may be a "Hycean" world — a class of exoplanet proposed in 2021 that has ...

The signal the astronomers report in the paper is actually the second such detection of the chemical or chemicals on the exoplanet. An “earlier, tentative inference of DMS” was made with one set of ...

the disintegrating exoplanet was discovered “almost by chance”; they were not looking for it. They became aware of it in the data from the TESS space telescope because its signal looked unusual.

Apparent signs of alien life on the exoplanet K2-18b may just be statistical noise, according to a new analysis of data from the James Webb Space Telescope. On 17 April, Nikku Madhusudhan at the ...

Astronomers have just uncovered fascinating signs we may not be alone in the universe. RNZ talks with an astrophysicist about what exactly the discovery tells us, and why it is unusual.

The planetary nature of this signal was confirmed by follow-up observations using ground-based facilities. "In this paper, we present the discovery of TOI-3493 b, a small exoplanet with a mass ...
