✨ Researchers have discovered an exoplanetary system, LHS 1903, located 116 light-years away, which challenges current planet formation theories.

✨ This system features four planets orbiting a red dwarf star, with a rocky planet found on the outermost orbit, beyond two gaseous planets. This arrangement contradicts the typical pattern of rocky planets being closer to the star.

✨ Scientists hypothesize that the outermost rocky planet, LHS 1903 e (a "super Earth"), formed later than the others in a gas-depleted environment, a novel "inside out" formation process.

✨ Data from NASA's TESS and ESA's Cheops, along with other telescopes, contributed to this discovery and ongoing analysis of this unique system.

⭐ Astronomers have identified 45 rocky exoplanets within the "habitable zone" that are most likely to support life, based on new data from ESA's Gaia mission and NASA's Exoplanet Archive.

⭐ This research, published in Monthly Notices of the Royal Astronomical Society, focuses on worlds that receive similar energy from their stars as Earth does from the Sun, a key factor for liquid water.

⭐ Among the most promising candidates are TRAPPIST-1 d, e, f, and g (40 light-years away) and LHS 1140 b (48 light-years away), with the James Webb Space Telescope and other future observatories set to study these targets.

Scientists backed by the Royal Astronomical Society have narrowed the search for alien life to 45 nearby Earth like planets, chosen for their similar size, temperature, and potential habitability, while also prioritizing those whose atmospheres future telescopes can study for possible signs of life.

🔭 Astronomers have identified 45 rocky exoplanets in their star's "habitable zone," the region where temperatures could allow liquid water.

✨ This research, published in Monthly Notices of the Royal Astronomical Society, helps pinpoint the best targets for finding extraterrestrial life, drawing inspiration from the movie Project Hail Mary.

🌍 A narrower, 3D habitable zone was also considered, identifying 24 additional worlds. The study also highlights planets receiving energy similar to Earth from their stars, like TRAPPIST-1 e and TOI-715 b, which are considered prime candidates for observation with telescopes like the James Webb Space Telescope.

🔭 Astronomers using the James Webb Space Telescope have detected water-ice clouds on Epsilon Indi Ab, a Jupiter-like exoplanet with 7.6 times Jupiter's mass.

🔬 These observations are a crucial step in understanding exoplanet atmospheres, particularly for the ongoing search for Earth-like planets, though more advanced telescopes will be needed for detailed Earth studies.

✨ The discovery highlights the need for more complex atmospheric models that account for clouds, pushing the boundaries of current exoplanet research.

⭐ New research from the University of Lancashire suggests planets may form more easily around double stars than single stars.

⭐ Computer simulations show a "forbidden zone" near binary stars where planet formation is difficult, but farther out, the discs become ideal for forming multiple giant planets, potentially even more than around single stars.

⭐ This research, published in Monthly Notices of the Royal Astronomical Society (MNRAS), indicates that real-life "Tatooines" (planets orbiting two stars) may be more common than previously believed, with over 50 already discovered.

✨ Astronomers have discovered two giant exoplanets, orbiting a star 1,110 light-years away, that are lighter than cotton candy. These "super-puffs" are the largest planets found with a density comparable to shaving foam.

🪐 Detected by NASA's Tess satellite, these planets have unusually long orbits, taking 139 and 232 days respectively to circle their host star in the constellation Volans.

🔭 The researchers used Earth-based telescopes to determine the planets' density, which is significantly lower than Jupiter's, making them the lightest known planets of their size.
