Astronomers using JWST have found potential signs of a life-supporting atmosphere on the exoplanet TRAPPIST-1e, located 40 light-years away, which could make it the most Earth-like planet discovered so far, though further observations are needed to confirm these findings.
Scientists have discovered an Earth-sized exoplanet, LTT 1445 Ac, that has a similar composition and density to Earth but is too hot to sustain life. It revolves around a red dwarf star and is part of a trinary star system. LTT 1445 Ac has 1.37 times the mass and 1.07 times the radius of Earth, making it the closest known Earth-sized exoplanet. By studying this exoplanet, scientists hope to gain insight into how terrestrial exoplanets function in different star systems. The James Webb Space Telescope will be used to further characterize LTT 1445 Ac and other exoplanets, advancing our understanding of planets similar to Earth.
Scientists have confirmed that the inner core of the Moon is a solid ball with a density similar to that of iron, settling a long-standing debate. By analyzing seismic data and conducting modeling, researchers found that the lunar core is similar to Earth's, with an outer fluid layer and a solid inner core. The findings support the existence of an active overturn in the lunar mantle and provide insights into the Moon's history and the timeline of the Solar System's early bombardment. The research also has implications for understanding the Moon's magnetic field and its eventual decline.
Scientists have confirmed that the moon has a fluid outer core and a solid inner core, similar to Earth's, after more than 50 years of research. The study also found the first evidence of mantle overturn on the moon, which may explain the presence of iron on its surface. Understanding the moon's inner workings can help scientists unravel its geologic mysteries and prepare for new lunar missions this decade.
Scientists have confirmed that the inner core of the Moon is a solid ball with a density similar to that of iron, similar to Earth's core. The discovery will help settle a long debate about whether the Moon's inner heart is solid or molten, and lead to a more accurate understanding of the Moon's history and that of the Solar System. The research was conducted by a team led by astronomer Arthur Briaud of the French National Centre for Scientific Research in France and published in Nature.
The James Webb Space Telescope has found that the rocky exoplanet TRAPPIST-1b, which orbits a star known as TRAPPIST-1, most likely has no atmosphere, dashing hopes that it might host life. However, there are six more Earth-like exoplanets in the TRAPPIST-1 star system, and now that Webb has proven its ability to study them, more exciting news may be forthcoming. Astronomers used the telescope's Mid-Infrared Instrument to measure the planet's temperature, revealing that it was too high for the planet to have an atmosphere.
