For the first time, astronomers have measured the spin-orbit alignment for a distant 'super-Jupiter' planet called Beta Pictoris b that located 63 light-years from...

New warm Jupiter alien world discovered

New warm Jupiter alien world discovered

The newfound exoplanet, designated TOI-677 b, is about 20 percent bigger and more massive than Jupiter.

This artist's illustration shows an alien world that is losing magnesium and iron gas from its atmosphere. The observations represent the first time that so-called "heavy metals"—elements more massive than hydrogen and helium—have been detected escaping from a hot Jupiter, a large gaseous exoplanet orbiting very close to its star.The planet, known as WASP-121b, orbits a star brighter and hotter than the Sun. The planet is so dangerously close to its star that its upper atmosphere reaches a blazing 4,600 degrees Fahrenheit, about 10 times greater than any known planetary atmosphere. A torrent of ultraviolet light from the host star is heating the planet's upper atmosphere, which is causing the magnesium and iron gas to escape into space. Observations by Hubble's Space Telescope Imaging Spectrograph have detected the spectral signatures of magnesium and iron far away from the planet.The planet's "hugging" distance from the star means that it is on the verge of being ripped apart by the star's gravitational tidal forces. The powerful gravitational forces have altered the planet's shape so that it appears more football shaped.The WASP-121 system is about 900 light-years from Earth. Credits: NASA, ESA, and J.

Hubble uncovers a heavy metal exoplanet shaped like a football

Observations by NASA's Hubble Space Telescope reveal magnesium and iron gas streaming from the heavy metal exoplanet known as WASP-121b.

This artist's concept shows planet KELT-9b, an example of a "hot Jupiter," or a gas giant planet orbiting very close to its parent star. KELT-9b is an extreme example of a hot Jupiter, with dayside temperatures reaching 7,800 degrees Fahrenheit (4,300 Celcius). Credit: NASA/JPL-Caltech

An artist's concept of the Kepler-1658 system. Sound waves propagating through the stellar interior were used to characterize the star and the planet. Kepler-1658b, orbiting with a period of just 3.8 days, was the first exoplanet candidate discovered by Kepler nearly 10 years ago. Credit: Gabriel Perez Diaz/Instituto de Astrofísica de Canarias
