Planetary Swing: Spitzer Space Telescope Probes Extreme Climates on Hot Jupiters and Super Earths

A simulation showing the turbulent atmosphere of exoplanet HD 80606b, based on data gathered with the Spitzer space telescope. This hot Jupiter-type world has one of the most elongated orbits known for an exoplanet, one that resembles the orbits of comets in our Solar System.

The Early Solar System Could Have Hosted a Fifth Giant Planet, According to New Study

Artist’s impression of a rogue gas giant planet, free-floating in interstellar space. According to a new study, the early Solar System hosted a fifth gas giant planet besides Jupiter, Saturn, Uranus, and Neptune, which was eventually ejected into interstellar space through the gravitational interactions with the rest of the Solar System’s giant planets. […]

Jupiter Might Be Responsible for Our Unusual Solar System, Study Suggests

A montage of Jupiter and its volcanic moon Io, as seen by NASA’s New Horizons spacecraft on its way to Pluto. The results of a new study indicate that the massive gas giant fundamentally altered the evolution of the early Solar System, by destroying any “Super-Earth”-type planets that may have formed, while opening […]

Under the Light of a Quadruple Sun: Astronomers Discover Additional Stellar Companions in Nearby Exoplanetary Systems

Artist’s conception of the quadruple star system 30 Arietis. The primary star, called 30 Arietis B, has a companion (the small “red dwarf” star shown at upper left). This pair of stars is itself locked in a long-distance orbit with another pair of stars (upper right), known as 30 Arietis A. A team […]
