Then the traceable tracks of “exocomets.” But 15 years ago this fall, the star system Beta Pictoris yielded one of the most iconic pictures in astrophysics: a direct image of a planet orbiting another star. The young, bright star, some 63 light-years distant and visible to the naked eye, all but overwhelmed the…

In a new study using NASA’s retired Kepler Space Telescope, astronomers find evidence of a possible cause: The cores of these planets are pushing away their atmospheres from the inside out. Exoplanets (planets outside our solar system) come in a variety of…

Scorching, Seven-Planet System Revealed by New Kepler Exoplanet List
A system of seven sweltering planets has been revealed by continued study of data from NASA’s retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system. Also unlike any of our immediate neighbors, all seven planets in this system, named Kepler-385, are larger than Earth but smaller…

Discovery Alert: The Planet that Shouldn’t Be There
NASA’s Exoplanet Exploration Program The discovery: A large planet is somehow orbiting a star that should have destroyed it. Key facts: Planet 8 Ursae Minoris b orbits a star some 530 light-years away that is in its death throes. A swollen red giant, the star would have been expected to expand beyond the planet’s orbit before receding to its present (still giant)…
