On Monday, scientists unveiled a powerful new technique to quickly validate transiting exoplanets. The method, known as the “Blender,” combines data gathered for both the Kepler and Spitzer Space Telescopes in an effort to identify tiny transiting exo-worlds that would otherwise go unnoticed by ground-based instruments.

Planetary Scientists may soon have a new technique in their arsenal in the hunt for exo-solar planets. Current tried-and-true methods involve measuring tiny radial velocity shifts, catching a gravitational lensing event, or watching and measuring a tiny dip in brightness as a planet transits its host star.

Some fairly thought provoking science has been coming out of the Royal Astronomical Society’s National Astronomy Meeting being held this week in Llandudno, Wales. One of the most interesting talks was by Dr. Robert Forsyth of Imperial College concerning a comparison of the current solar lull and the famous Maunder minimum of 1645-1715. [Read more...]

A new and innovative tool in the hunt for extra-solar worlds just came to our attention recently. Traditionally, to find these elusive beasts, astronomers utilized ground-based instruments to detect transits, Doppler shifts, and even the occasional odd gravitational lensing event. [Read more...]
