Earth's Infrared Secrets: The Key to Finding Life on Distant Worlds

  • 3 תגובות
The plan is to place five small satellites in space close to the Webb Space Telescope. Together these telescopes will act as a large telescope that will be used as an interferometer to receive infrared heat radiation from extrasolar planets. Finding life on Earth will give a good calibration of the spacecraft

The James Webb Space Telescope reveals the unseen forces that shape planetary systems

Researchers studying the Orion Nebula with the James Webb Space Telescope found that ultraviolet radiation from massive stars prevents the formation of giant planets in young systems by scattering their building materials.
Astronomers have found water vapor in the disk around a young star right where planets are likely to form. In this image, the new observations from the ESO partner Atacama Large Millimeter/Submillimeter Array (ALMA) show the water vapor in shades of blue. Near the center of the disc, where the young star lives, the environment is hotter and the gas is brighter. The red rings are previous ALMA observations showing the distribution of dust around the star.Credit: ALMA (ESO/NAOJ/NRAO)/S. Facchini et al.

Hubble observes changes in the atmosphere of a planet outside the solar system

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
Research shows that giant gas planets in other star systems often prevent the habitability of neighboring Earth-like planets by disrupting orbits and climates. An artist's rendering of an exoplanet system full of giant planets. Credit: NASA/Dana Berry

Chaos rules the cosmos: How giant gas planets threaten life on nearby Earth-like worlds

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.

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

"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.
