Discovery Alert: An Ice-Cold Earth?

A candidate planet that might be remarkably similar to Earth, HD 137010 b, has one potentially big difference: It could be colder than perpetually frozen Mars.

Discovery Alert: With Six New Worlds, 5,500 Discovery Milestone Passed! - NASA Science

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 decades, this new milestone marks another major step in the journey to […]

Discovery Alert: An Earth-sized World and Its Ultra-cool Star - NASA Science

Our galaxy is a jewel box of red stars. More than 70% of the stars in the Milky Way are M dwarfs, also known as red dwarfs. These stars are cool and dim compared with our Sun, but they often blast orbiting exoplanets with high-energy radiation, especially early in their lives. And those ‘‘lives’’ last […]

NASA's Hubble Measures the Size of the Nearest Transiting Earth-Sized Planet - NASA Science

NASA’s Hubble Space Telescope has measured the size of the nearest Earth-sized exoplanet that passes across the face of a neighboring star. This alignment, called a transit, opens the door to follow-on studies to see what kind of atmosphere, if any, the rocky world might have. The diminutive planet, LTT 1445Ac, was first discovered by […]
