Scientists might have just found Earth's icy, distant cousin a few hundred million light-years away. HD 137010 b is one of thousands of exoplanets, or planets that orbit other stars, and is ...

Add Yahoo as a preferred source to see more of our stories on Google. In our solar system, Earth is one of but eight planets – nine, if you really want to count Pluto – and the only one remotely ...

The James Webb Space Telescope (JWST) has notched another milestone, capturing a direct image of a distant, frigid planet in a solar system unlike our own, astronomers announced on June 10. The ...

Thirty years ago, astronomers didn’t know if planets around other stars were common. Today, NASA says we’ve confirmed 6,000 exoplanets — a staggering number considering the first definitive discovery ...

Irvine, Calif., July 14, 2025 — In new research, University of California, Irvine astronomers describe how more than 200 known exoplanets are likely much larger than previously thought. It’s a finding ...

One of the largest known exoplanets is losing itself to space and will break apart in the next half a billion years 1. The planet, known as HAT-P-67 b, is a little more than twice the size of Jupiter ...

The atmospheres of exoplanets have been a focal point of the field lately, with the James Webb Space Telescope taking a look at as many as it can manage. But time on the world's most powerful space ...

Anew study led by Robb Calder at the University of Cambridge suggests that nearly all known sub-Neptune exoplanets, previously thought to be potential ocean-bearing“hycean worlds,”are far more likely ...

A new analytical transmission model incorporating pressure-dependent opacity improves interpretation of exoplanet atmospheres and supports data analysis from JWST and the upcoming ARIEL mission.

Surprised astronomers just discovered a world that blurs the line between planet and stellar remnant, hiding in a system known as a “black widow.” “This was an absolute surprise,” said study co-author ...
