Webb Telescope Reveals Surprising Atmosphere on Ancient Lava Planet

NASA's JWST has provided the strongest evidence yet that the ultra-hot super-Earth exoplanet TOI-561 b, despite its extreme conditions, possesses a thick, volatile-rich atmosphere, challenging previous assumptions about small, hot planets losing their atmospheres. The findings suggest this planet has retained its atmosphere, possibly due to a balance between atmospheric escape and magma ocean absorption, opening new questions about planetary evolution in harsh environments.

Nearby Star Hosts Newly Discovered Super-Earth Exoplanet

Astronomers using NASA's TESS have discovered a super-Earth exoplanet, TOI-1846 b, orbiting a nearby M dwarf star about 154 light years away. The planet is roughly twice Earth's size, four times its mass, and likely water-rich, orbiting its star every 3.93 days. The discovery adds to TESS's catalog of over 7,600 candidate exoplanets and highlights the potential for further studies to determine its composition.

Scientists Discover a Potentially Habitable Super-Earth in a New Exoplanetary Frontier

Scientists have discovered a super-Earth named Kepler-725c in the habitable zone of its star using the transit timing variation method, which allows detection of planets that are otherwise difficult to observe directly. This planet, about 2,472 light years away, could potentially support life due to its location and size, marking a significant step in the search for Earth-like worlds beyond our solar system.

Scientists Discover a Super-Earth in the Habitable Zone, Boosting Search for Extraterrestrial Life

A super-Earth exoplanet named Kepler-735c, orbiting 2,472 light years away, was discovered indirectly through transit timing variations, revealing its highly elliptical orbit and partial habitability due to its changing position relative to its star. This discovery highlights the potential of TTVs to find planets on wider orbits and in habitable zones, expanding our understanding of exoplanets and the search for life.

Potential Super-Earth Threatens Earth's Safety

Researchers from the Florida Institute of Technology propose that a hypothetical super-Earth, named Phaedra, located between Mars and Jupiter, could have destabilized Earth's climate, making it uninhabitable. Their models suggest that even a planet twice Earth's mass could cause chaotic seasonal shifts, while a planet 10 to 20 times larger would render Earth inhospitable. This raises concerns about the potential dangers of super-Earths, which are common in the galaxy, to nearby planets' habitability.

Super-Earth's Lead-Like Density Sets New Record

Astronomers have discovered K2-360 b, a Super-Earth exoplanet with a density comparable to lead, making it the densest known planet in its class. This rocky world, possibly the remnant core of a gas giant, orbits its star in just 21 hours. The planet's high density is attributed to a large iron core, and its formation may involve high-eccentricity migration influenced by a larger companion planet, K2-360 c. The findings highlight the diversity of planetary systems in the universe.
