Chandra Discovers Planet That Makes Star Act Deceptively Old

A new study from NASA’s Chandra X-ray Observatory shows that a giant exoplanet, WASP-18b, is making the star that it orbits act much older than it actually is. WASP-18b is over ten times Jupiter’s mass and is so close to its star that it completes an orbit in less than a day, causing extreme tidal […]

Hot Jupiters Make Their Suns Wobble

A new study from Cornell University shows that when the “Hot Jupiters” approach their host star, the planet can force the star’s spin axis to precess much like a wobbling, spinning top. According to new Cornell research published in Science, these large, gaseous exoplanets can make their suns wobble after they wend their way through […]
