(Phys.org)—Astronomers have detected four new giant exoplanets as part of the Hungarian-made Automated Telescope Network-South (HATSouth) exoplanet survey. The newly found alien worlds are about the size of Jupiter, but ...
Researchers at Uppsala University plan to manufacture a new type of coronagraph for the VLT, the Very Large Telescope in Chile. The coronagraph is a key component of the telescope which will be used to search for planets ...

(Phys.org)—An international team of astronomers led by Joel Hartman of Princeton University has detected two new "hot Jupiter" exoplanets, less massive than our solar system's biggest planet, but with a radius larger than ...
Planets develop from the dusty placental disk of material that surrounds a star after it begins to shine. The dust in that disk, according to most models, starts to stick to itself until clumps develop large enough to attract ...

(Phys.org)—An international team of astronomers has reported the discovery of a new giant extrasolar planet orbiting a subgiant star so closely that it should be destroyed due to tidal interactions. However, against all ...
Through a computer-simulated study, astronomers at Lund University in Sweden show that it is highly likely that the so-called Planet 9 is an exoplanet. This would make it the first exoplanet to be discovered inside our own ...
