Since their first discovery in 1995, hot Jupiter exoplanets (hot Jupiters, for short) quickly challenged our understanding of exoplanet formation and evolution, including exoplanetary system architecture. This is because, as their name implies, they orbit at extremely close distances to their host stars, ranging from a few days to a few hours. Some of their orbits are even oval-shaped, called eccentric in the scientific community, meaning their orbit is oval-shaped. But could such an orbit cause a hot Jupiter to completely vanish from view, preventing astronomers from studying it? Now, an international team of researchers might have shed new light on the fate of hot Jupiters, as they present new findings announcing the discovery of a hot Jupiter whose eccentric orbit tilt could change in less than a decade, preventing astronomers from observing it. This study was recently published in the Publications of the Astronomical Society of Japan and could help astronomers better understand the evolution of hot Jupiters with eccentric orbits and whether this orbital tilt change is common across other exoplanets. For the study, the researchers examined transit data from the hot Jupiter, TOI-1355 b, which is located about 805 light-years from Earth, has a mass and radius...

The distant gas giant's shifting eccentric orbit offers a limited-time chance to study how hot Jupiters evolve before its transits become undetectable from Earth.

Isotope analysis of returned Bennu samples suggests the asteroid formed near the water-ice line under Jupiter's influence, reshaping theories of early solar system chemistry.

The gas giant Beta Pictoris b, about 63 light-years away, has the mass of 10 Jupiters and a magnetic field thousands of times as strong as Earth’s.
