An exoplanet is a planet from a different star system. Most known exoplanets orbit stars within the Milky Way, but with the help of powerful space telescopes, scientists have discovered exoplanets ...

New findings made possible by the James Webb Space Telescope reveal that the Earth-like exoplanet Trappist-1 b may have an atmosphere after all, potentially overturning earlier findings. Approximately ...

"One plus one is more than two — having two data points for TRAPPIST-1b now allows us to explore alternative scenarios for its atmosphere, whether it exists or not." The innermost Earth-like ...

“The average exoplanet person doesn’t care about asteroids,” says study coauthor Artem Burdanov, a planetary scientist at the Massachusetts Institute of Technology. To those studying far ...

Astronomers largely circumvent this problem by instead observing the side of an exoplanet heated by the star in the thermal infrared light, as in the current study with TRAPPIST-1 b. The bright ...

Does the exoplanet Trappist-1 b have an atmosphere after all?. ScienceDaily . Retrieved January 3, 2025 from www.sciencedaily.com / releases / 2024 / 12 / 241216130034.htm ...

Cool, red dwarf stars often exhibit large starspots and strong eruptions, significantly affecting the measurement. Astronomers largely circumvent this problem by instead observing the side of an ...

Since the first discovery of an exoplanet in 1995, over 5,000 exoplanets, or planets orbiting other stars, have been found. Many of these exoplanets are small and rocky, like Earth, and in the ...

The exoplanet, WASP-69 b, is a gas giant. It's around the same size as Jupiter but less than a third as massive, and orbits a main sequence star roughly 160 light-years from Earth.

For the study, published Monday in the journal Nature, they employed an image processing technique originally used to search for exoplanets. As a result, they spotted the smallest asteroids ever ...

To date, TESS has identified more than 7,300 candidate exoplanets (TESS Objects of Interest, or TOI), of which 571 have been confirmed so far. Since its launch in April 2018, the satellite has ...
