A light curve from NASA’s James Webb Space Telescope’s Near-Infrared Spectrograph (NIRSpec) shows the change in brightness from the LHS 475 star system over time as the planet transited the star on August 31, 2022. LHS 475 b is a rocky, Earth-sized exoplanet that orbits a red dwarf star roughly 41 light-years away, in the constellation Octans.
NASA's Exoplanet Archive confirmed four new worlds, bringing the total past 5,500. On Aug. 24, 2023, more than three decades after the first confirmation of planets beyond our own solar system, scientists announced the discovery of six new exoplanets, stretching that number to 5,502. From zero exoplanet confirmations to over 5,500 in just a few ...
Rare "in-sync" solar system discovered by scientists 04:12. Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside ...
NASA/JPL-Caltech. The discovery: A “super-Earth” ripe for further investigation orbits a small, reddish star that is, by astronomical standards, fairly close to us – only 137 light-years away. The same system also might harbor a second, Earth-sized planet. Key facts: The bigger planet, dubbed TOI-715 b, is about one and a half times as ...
Astronomers have identified a new exoplanet orbiting Barnard’s star, the closest individual star to our solar system, situated just six light-years away. This newly discovered planet, named ...
JWST also got its first direct spectrum of an object orbiting a star in another solar system Exoplanet HIP 65426 b shines in four different wavelengths in this image from the James Webb Space ...
Although LHS 475 b is closer to its star than any planet in our solar system, its red dwarf star is less than half the temperature of the Sun, ... In a system with two known planets, astronomers spotted something new: a small object transiting across the Sun-sized star. This turned out to be another planet: extra hot and Earth-sized. January 10 ...
Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. (“Small” meaning within thousands of light-years of our solar system; one light-year equals 5.88 trillion miles, or 9.46 trillion kilometers.) Even the closest known exoplanet to Earth, Proxima Centauri b, is still about 4 light-years […]
November 29, 2023 at 11:00 a.m. EST. Astronomers have discovered a six-pack of planets, formed at least 4 billion years ago and remarkably unchanged since, orbiting a nearby sun-like star. The new ...
The new planets, HD 260655 b and HD 260655 c, are among the closest-known rocky planets yet found outside our solar system that astronomers can observe crossing the faces of their stars. Key facts: Using NASA’s orbiting planet hunter, the Transiting Exoplanet Survey Satellite (TESS), scientists discovered sibling planets in Earth’s size ...
