This exoplanet orbits around its star's poles

In 1992, humanity's effort to understand the universe took a significant step forward. That's when astronomers discovered the first exoplanets. They're named Poltergeist (Noisy Ghost) and Phobetor (Frightener), and they orbit ...

Estimating the magnetic field of an exoplanet

Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, they managed to estimate ...

Spitzer telescope puts planets in a petri dish

(Phys.org) —Our galaxy is teeming with a wild variety of planets. In addition to our solar system's eight near-and-dear planets, there are more than 800 so-called exoplanets known to circle stars beyond our sun. One of ...

Can we spot volcanoes on alien worlds? Astronomers say yes

Volcanoes display the awesome power of Nature like few other events. Earlier this year, ash from an Icelandic volcano disrupted air travel throughout much of northern Europe. Yet this recent eruption pales next to the fury ...

Researchers use 'hot Jupiter' data to mine exoplanet chemistry

After spotting a curious pattern in scientific papers—they described exoplanets as being cooler than expected—Cornell University astronomers have improved a mathematical model to accurately gauge the temperatures of planets ...

New 'hot Jupiter' with short orbital period discovered

(Phys.org)—An international team of astronomers reports the discovery of a new "hot Jupiter" exoplanet with a short orbital period of just three and a half days. The newly detected giant planet, designated KELT-20b, circles ...

Early exit for hot Jupiter due to deadly tides

(PhysOrg.com) -- Bad news for planet hunters: most of the "hot Jupiters" that astronomers have been searching for in star clusters were likely destroyed long ago by their stars. In a paper accepted for publication by the ...
