planets outside the solar system
An amount of water at least three times greater than the water in all the Earth's oceans was discovered in the inner disk of the young Sun-like star HL Tauri, 450 light-years away from Earth, in the Taurus group
A newly discovered solar system with six confirmed extrasolar planets and a possible seventh increases astronomers' knowledge of star formation and evolution
Beta Pictoris is a solar system in the making and relatively close so that the gas disks can be seen. It turns out that Webb was able to discover a structure that was not noticed in photographs with less sensitive instruments, thus he discovered a disk of gas tilted from our main disk and because of our vantage point it looks like a cat's tail
An international team of astronomers compiled and reprocessed observations of the extrasolar planet WASP‑121 b collected by the Hubble Space Telescope in 2016, 2018 and 2019 and noticed weather patterns on its surface. It is a hot Jupiter-type planet - that is, on the order of Jupiter but very close to its sun
Jupiter, the largest planet by far in our solar system, plays an important protective role. Its enormous gravitational field deflects comets and asteroids that might otherwise hit Earth, helping to create a stable environment for life to exist. But giant planets elsewhere in the universe don't necessarily protect life in their smaller, rocky neighbors.
An international team of astronomers discovered a system of six planets orbiting the star HD110067 in a unique harmonic resonance
The TESS space telescope discovered a planet that survived a merger between two stars as the merged star swelled to become a red giant
NASA's Nancy Grace Roman space telescope, which will be launched in May 2027, will be able to find an astonishing number of 400 Earth-mass stray worlds. Indeed, in the new study, one such candidate has already been identified
Protoplanets form from clumps of material in disks around newborn stars. When the planet is still forming, that is, when it is still collecting material, it is called a protoplanet. This is only the third protoplanet discovered
An international team of astronomers has announced the discovery of a second planet in the circumbinary system (where planets orbit two suns) of the rare multiple planet BEBOP-1. This planet was discovered using the transit method and was noticed because it passed in front of the brighter of the two stars on different occasions
A new study suggests that a third of the planets orbiting dwarf stars common to the Milky Way could potentially support life. As in the story of Goldilocks and the Three Bears, one plate is too hot, the second is too cold and the third is just right
"The planet is completely covered in a kind of layer of fog or clouds," said Eliza Kempton, a researcher at the University of Maryland and lead author of a new paper on the planet published in Nature. "The atmosphere simply remained completely hidden from us until this observation." She noted that if the planet was indeed rich in water, it could have been a "water world", with large amounts of water and ice material at the time of its formation.
The belts surround the hot young star, which can be seen with the unaided eye as the brightest star in the southern group Southern Pisces. The dust belts are fragments from the collisions of larger bodies, corresponding to asteroids and comets, and are often described as "fragment disks"
For the first time, the temperature of a rocky planet was measured, as well as a planet similar to Jupiter but containing large amounts of heavy elements
The study, published in the Astrophysical Journal, was led by researchers from the University of Arizona and the California Institute of Technology. The team used data from NASA's Kepler space telescope launched in 2009 to search for exoplanets, or planets orbiting stars other than our sun
However, the conditions there are more reminiscent of Venus than Earth. It orbits a red dwarf in an orbit that lasts only two days * Webb was able to confirm the existence of the planet after only two orbits
A computerized system classifies the atmospheres of planets outside the solar system. and determines which of them are capable of sustaining human settlement in the future
Researchers at the University of Sheffield have proposed a new source for Jupiter-like planets orbiting massive stars three times the mass of our Sun
The spectral analysis of TOI-1452 b shows that water may make up to 30% of the planet's mass, a proportion similar to that of several moons in our solar system, such as Jupiter's moons Ganymede and Callisto, and Saturn's moons Titan and Enceladus. The mass of water is only 1%
The light spectrum - which contains information about the composition of a planetary atmosphere 1,150 light years away - reveals a clear signature of water * The strength of the signal that Webb detected hints at the significant role that the telescope will play in the search for potentially habitable planets in the coming years
Every ten years since the XNUMXs, astronomers and astrophysicists in the U.S. have gathered to compile a list of priorities for means and instruments. These surveys require scientists to think about priorities
NASA's Breakthrough Initiative, Saber Astronautic, and JPL have announced Project Tolliman, a project to find out whether the nearest stars have planets that could support life
