Astronomers detect possible Radio Emission from Exoplanet

By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Boötes — that could be the first radio emission collected from a planet beyond our solar system.

The team, led by Cornell postdoctoral researcher Jake D. Turner, Philippe Zarka of the Observatoire de Paris — Paris Sciences et Lettres University and Jean-Mathias Griessmeier of the Université d’Orléans will publish their findings in the forthcoming research section of Astronomy & Astrophysics, on Dec. 16.

“We present one of the first hi...

First detection of Gases at Super-Earth show a light-weight, dry atmosphere – with a hint of Carbon too?

This artist's impression shows the super-Earth 55 Cancri e in front of its parent star. Using observations made with the NASA/ESA Hubble Space Telescope and new analytic software scientists were able to analyse the composition of its atmosphere. It was the first time this was possible for a super-Earth. 55 Cancri e is about 40 light-years away and orbits a star slightly smaller, cooler and less bright than our Sun. As the planet is so close to its parent star, one year lasts only 18 hours and temperatures on the surface are thought to reach around 2000 degrees Celsius. Credit: ESA/Hubble, M. Kornmesser
