Rensselaer Polytechnic Institute’s Moussa N’Gom, assistant professor of physics, applied physics, and astronomy, has devised a method to make communications between satellites and the ground more effective no matter the weather. In research recently published, N’Gom and his team used ultrafast, femtosecond lasers to cut through the clouds and rain that commonly cause losses in free-space optical communication (FSO).

Are there other Earth-like planets? Is there extraterrestrial life? In the quest to find planets that orbit stars other than the sun, “Earth 2.0” is the Holy Grail. Earth 2.0 is a planet similar enough to Earth to enable the existence of life as we know it. It would be the right temperature for liquid water, and it would orbit a star with a steady supply of light. Ideally, it would be close enough that we could imagine going there or at least sending a probe to explore it.
