Satellite imagery portraits Planet Earth

Weddesigner Depot has posted 60 images of Earth taken by Landsat7 satillites in space.  “Various combinations of the eight Landsat 7 spectral bands were selected to create [these] vivid RGB composites.”  These images are beautiful and really put into perspective how expansive and breathtaking our planet truly is.  Enjoy some more satellite compositions in the gallery below, and head over to Webdesigner Depot to see the rest.

Astronomers find a nearby water-rich “super-Earth”

Astronomers have discovered GJ 1214b, a nearby planet that contains (supposedly) a plethora of water.  The 40-light years away planet is labeled a “super-Earth” because it’s recorded to be 2.7 times as large as Earth (and technically because it is between one and 10 times as large as Earth).  It orbits a star that is much smaller and less bright than our sun.  To the surprise of many scientists, this planet was sitting right underneath our noses; it was spotted “using an amateur-sized, 16-inch telescope on the ground.”  They never spotted it in the past because researchers don’t normally look for planets that orbit small stars.  David Charbonneau, a Harvard professor of astronomy: “Nature is just far more inventive in making planets than we were imagining.”  For those of you hoping that GJ 1214b contains life similar to that found on our Earth I have unfortunate news.  It’s been reported that its atmosphere is too thick and hot to support life like ours.  This being said, Charbonneau describes this as a breakthrough discovery and leaves the possibility of living organisms open due to the fact that the planet does contain water.  Now how about giving GJ 1214b a real name; it’s a start.
