Telescope big enough to detect planets outside the solar shadows against other stars?
Is it possible to create a telescope space (Hubble-like) sufficient to detect the shadow of the planet passing in front of other stars. What size telescope would need to see these planets around Alpha Centauri that way? For example, mercury can be seen crossing the sun with some filters: http://www.nasa.gov/images/content/162674main_mercury_transit_1024.jpg O Venus: http://lakdiva.org/2004egypt/transit/venus_sun1.jpg
* We've found planets by observing how light from a star decreases the brightness of a planet in the future. We've even been able to find a little of what the world is made. In fact, * * See the planet is a very different thing. We have yet to see a star disc of normal size (although we have some characteristics red giant), and a planet is much smaller than that. More precisely, suppose we have a radius of Jupiter-sized (71,000 km) at a distance 5 light years (a little more of Alpha Centauri) and we try to see in visible light. I can get a telescope diameter of the order 400 meters or more *. * That's about a quarter mile. If you want to see a planet the size, diameter should be about 12 times larger.
