Future Telescopes * a cleanly proposed Exo-Earth Imager (EEI) could show astronomers an Amazon-size forest, with its green breathing space of biology, on an Earth-size planet 30 light historic layover away. *Its a dauntless promise, considering that NASA and the European Space Agency are still a dozen years away from unconstipated attempting a terrestrial Planet Finder (TPF) that could ba stray see such worlds as tiny specks. *One NASA thought envisions a spaceborne array of 20 telescopes, each 26 feet in diameter separated by as much as 3,700 miles in space. *the EEI would use umpteen little mirrors instead of a few big ones, and would rely on a new technique called densified pupil resourcefulness to get the most from the insufficient amount of light reflected from a distant planet. *It would need one hundred fifty telescopes, each 10 feet ample, staged in three concentric circles, with a baseline of one C miles or so. It should be able to return snapshots 30 to 4 0 picture elements (pixels) wide of an Earth-size planet 10 light years away. *Study teams in Europe and the United States will retain a block look at the proposal for a scaled-down, 36-telescope version called the Exo-Earth sentry to see if it can be satisfactory for the TPF design * structure and flying 150 spacecraft in ultra-precise make-up is no cheap or easy task.

*the observatory hopes to acquire examination the principles of a hyper-telescope with a ground-based array called CARLINA former(prenominal) in the come up future Comets, meteoroids, and asteroids Comets: *chunks of dirt, rock, ice that o rbit the Sun on unbelievably large orbits f! rom out beyond Pluto/Neptune * lengthen orbits * once in a while we see them when they are close to the Sun *the Suns radiation vaporizes about of the comets ices producing observable long flowing tails of and dust particles. *When take away from...
