21 hours ago · How we found super-Earth HD 20794 d Confirming the discovery of exoplanet HD 20794 d demanded two decades of meticulous observations using the world’s most sophisticated instruments. Among them are ESPRESSO and HARPS, high-precision spectrographs that are critical in detecting subtle signals from exoplanets.

1 day ago · The exoplanet’s size, proximity to Earth, and potential to hold water makes it a prime candidate to search for life, as well as testing hypothesis about conditions that could support it.

2 days ago · Thirty years after the discovery of the first exoplanet, astronomers have detected more than 7,000 of them in our galaxy. But there are still billions more to be discovered. At the same time ...

2 days ago · With its location in a habitable zone and relatively close proximity to Earth, this planet could play a pivotal role in future missions that will characterise the atmospheres of exoplanets to search for biosignatures indicating potential life.

Jan 23, 2025 · An exoplanet is any planet beyond our solar system. Most of them orbit other stars, but some free-floating exoplanets, called rogue planets, are untethered to any star. We’ve confirmed more than 5,800 exoplanets out of the billions that we believe exist.

Aug 6, 2024 · Scientists have found over 5,000 exoplanets since the first such world was confirmed orbiting a sunlike star in 1995. We explore the ones most similar to Earth.

Jan 23, 2025 · When you select a planet’s name, see a visualization of each world and system, along with vital statistics. Filter by exoplanet type, by discovery method, or by the mission or facility that found it.

Oct 28, 2024 · The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth — a so-called super-Earth. Data from a worldwide array of telescopes, including ESO’s planet-hunting HARPS instrument, have revealed this frozen, dimly lit world.

Jan 12, 2023 · NASA’s James Webb Space Telescope has discovered its first Earth-like exoplanet, and for the first time, researchers will be able to examine the planet’s atmosphere.
