A new technique to explore the atmospheres of planets outside our solar system

'Tau Bootis b' was one of the first exoplanets discovered in the 90's. Fifteen years later, remains one of the closest known and given that it already has confirmed the existence of 750 planets outside our solar system, which number about 2,000 applicants to join the list.

'Tau Bootis b' is a big 'hot Jupiter' orbiting close to its host star. Although its host star is easily visible, so far this planet could only be detected by its gravitational effects on the star.

A strange hot spot on a planet from outside our solar system

The Spitzer Space Telescope NASA has exposed a strange point of heat in a planet outside our solar system in the Andromeda group, 44 light years from the Earth. The planet, Upsilon Andromeda, is a massive such as 'hot Jupiters', named for its high temperatures and gas formation. The strange thing, the mystery that scientists cannot manage to explain, is that this extraordinary heat zone is located in a part of the planet in which there should be, away from exposure to the star, which contradicts all theories known.

Earth Meteorite flies only 14 000 kilometers higher than the Earth's outside

Recently, a newly discovered meteorite, 2012 KT42, flew past Earth at only 14,000 miles above the surface of our planet, so flying within the belt of geosynchronous satellites.

According to the orbit of this asteroid, fortunately there was no danger of collision, despite its proximity to Earth.

Moreover, in any case, due to its small size would probably have disintegrated upon entering our atmosphere.
