NASA Space Telescope Sees the Light from an Alien Super-Earth

artist's concept of 55 Cancri e, a toasty "super-Earth" that rushes around its star every 18 hours.NASA’s Spitzer Space Telescope has detected light emanating from a “super-Earth” beyond our solar system for the first time. While the planet is not habitable, the detection is a historic step toward the eventual search for signs of life on other planets.

The planet, called 55 Cancri e, falls into a class of planets termed super Earths, which are more massive than our home world but lighter than giant planets like Neptune. The planet is about twice as big and eight times as massive as Earth. It orbits a bright star, called 55 Cancri, in a mere 18 hours.

  1. So when ya’ll need someone to explore space and move where ever whenever and do whatever needs to be done mark me first on the list.

  2. According to the link referenced in the post, the 55 Cancri system is relatively close to Earth, at 41 light-years away. It has five planets, with 55 Cancri e the closest to the star and tidally locked, so one side always faces the star. Spitzer discovered the sun-facing side is extremely hot, indicating the planet probably does not have a substantial atmosphere to carry the sun’s heat to the unlit side.

  3. The work being Dona by Nasa and it’s staff is undeniably necessary and I hope it is never hope it continues for a many more generations.
