Space telescope offers rare glimpse of Earth-sized rocky exoplanet

- Direct observations from a NASA space telescope have for the first time revealed the atmospheric void of a rocky, Earth-sized world beyond our own solar system orbiting the most common type of star in the galaxy, according to a study released on Monday.

Known to astronomers as LHS 3844b, this exoplanet about 1.3 times the size of Earth is locked in a tight orbit - one revolution every 11 hours - around a small, relatively cool star called a red dwarf, the most prevalent and long-lived type of star in the galaxy. The principal finding is that it probably possesses little if any atmosphere - a conclusion reached by measuring the temperature difference between the side of the planet perpetually facing its star, and the cooler, dark side facing away from it.
