Fomalhaut b exoplanet may have been cloud in a trench coat: Massive ‘world’ formed after ‘mid-space super-prang’

Another one bites the dust A massive exoplanet some 25 light years away may be nothing of the sort, astroboffins now believe – which isn’t surprising seeing as it just vanished. In 2008, after four years of observations using the Hubble Space Telescope, scientists announced the discovery of Fomalhaut b. Yet by 2014, the object…

Iron rain on exoplanet is driven by huge extremes in temperature

Singing in the iron rain: a fanciful illustration of WASP-76b. (Courtesy: Frederik Peeters/ESO) It could be raining molten iron on some exoplanets, according to David Ehrenreich at the University of Geneva and an international team of astronomers. The team discovered evidence for the metallic precipitation in atmospheric spectra of the giant, ultra-hot planet WASP-76b that…

Exoplanet Is ‘Most Promising Candidate so Far’ to Harbor Life: Scientists

Investigations into the exoplanet K2-18b have revealed that the distant world could harbor the right conditions for life to exist.Last year, the planet—which is located around 124 light-years away in the so-called “habitable zone” around its host star—made headlines when scientists identified water vapor in its hydrogen-rich atmosphere.However, just because water vapor is present in…

Giant exoplanet orbiting tiny star defies current theory of planet formation

Unexpected giant: artist’s impression of the planet GJ 3512b orbiting its red dwarf host star. (Courtesy: Guillem Anglada-Escude – IEEC/Science-wave/CC BY 4.0) An exoplanet with about half the mass of Jupiter has been spotted orbiting a red dwarf star, challenging astronomers’ current theories of planet formation. Picked up by the CARMENES red dwarf survey, the…
