Gas giant exoplanet WASP-69b has captured the attention of astronomers, this time because of the trail of gas it's leaving behind – a tail that's some seven times longer than the planet's radius.This tail is being created as the atmosphere of WASP-69b gets stripped away, making it a fascinating celestial object to study. Around the size of Jupiter, the planet is 160 light-years away from Earth, and sits unusually close to its star.That close proximity is the main reason for the elongated tail, according to the team…

The space-based TESS satellite that uses the transit method to measure the small drops of a stellar light when an exoplanet passes in front of it. TESS allowed for the characterization of the sub-Neptune HD88986b by accurately determining the size of the planet.

New research redefines the Habitable Zone of exoplanets by considering subglacial liquid water, extending potentially habitable conditions beyond traditional boundaries. Supported by recent JWST observations, this study broadens the scope for finding life on exoplanets, especially those orbiting M-dwarf stars.Professor Amri Wandel from the Hebrew University of Jerusalem has introduced groundbreaking research with the potential to transform our understanding of habitable exoplanets. His latest study, published in the…

An amusing rendition of the TOI-1136 system if each body in the system were a duck or duckling. Credit: Rae Holcomb/UCISix-exoplanet system offers glimpse into planet formation and evolution.With an arsenal of advanced technology, scientists have found a multi-planet star system that provides a rare insight into the way planets form and behave around a young star.TOI-1136 is a dwarf star in the Milky Way galaxy more than 270 light-years from Earth, which is considered nearby, as the Milky Way is 100,000 light years in…

An international research team, using the European XFEL X-ray laser, has uncovered new details about diamond rain on planets like Neptune and Uranus, revealing its potential effect on their magnetic fields and existence on smaller exoplanets.

Astronomers have discovered a new Earth-sized exoplanet, HD 63433 d, in the HD 63433 planetary system, utilizing data from NASA’s TESS. This tidally locked planet is the youngest and closest Earth-sized exoplanet found, being less than 500 million years old. Orbiting very close to a Sun-like star, it experiences extreme temperatures, making it a unique subject for further study.

The Hubble Space Telescope has observed the smallest planet outside our solar system to contain water vapor in its atmosphere, a "landmark discovery" that brings astronomy a step closer to characterizing Earth-like worlds.At around twice Earth's diameter, planet GJ 9827d orbits a red dwarf star 97 light-years away in the constellation Pisces, NASA and the European Space Agency (ESA) said in statements on Thursday.The team behind the finding are examining two scenarios: either the planet is a "mini-Neptune" with a…

Astronomers using Hubble have detected water vapor in the atmosphere of GJ 9827d, a small exoplanet, suggesting the presence of water-rich atmospheres on similar planets. This discovery marks a significant step in exploring the composition and evolution of exoplanetary atmospheres. credit: SciTechDaily.comSteamy World Could Be a Sample of Water-Rich Planets Throughout Our GalaxyThe search for life in space goes hand-in-hand with the search for water on planets around other stars. Water is one of the most common molecules…

Astrophysicists studying the exoplanet WASP-69b have discovered it possesses a comet-like tail, seven times longer than the planet itself. This phenomenon occurs as the planet’s gaseous atmosphere is stripped away and elongated by its perilously close orbit to a hot star and the influence of stellar winds. This real-time observation offers insights into the evolutionary processes of thousands of other planets in our galaxy (Artist’s impression). Credit: SciTechDaily.comScientists state that this discovery offers a rare…

Researchers have identified HD 63433d, an Earth-sized planet that is both closer and younger than previously discovered planets of similar size. Its proximity to a youthful, sun-like star provides a unique case study for planetary evolution. (Artist’s concept.) Credit: SciTechDaily.com“It’s a useful planet because it may be like an early Earth”HD 63433d, a new Earth-sized planet discovered by astronomers, offers a rare glimpse into the early stages of planet evolution, given its close orbit around a young sun-like star.A…
