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.

In the solar system shown a new planet

Exposed a new category of planets appear to suggest alone in space. This is called roaming worlds, which, far from any star, wandering through interstellar space after being ejected from planetary systems in which they formed. Now, new research from the Harvard-Smithsonian Center for Astrophysics suggests that these worlds’ nomads can find a new home with a different sun. He even claims that billions of stars in our galaxy may have caught wandering planets. This finding, which will be published in the journal Astrophysical Journal, could explain the existence of planets orbiting some surprisingly far from their stars, and even the existence of a double planet.

Our solar system is not protected from the rest of the galaxy. Why?

Fresh explanation of the solar system's borders have unwavering that the Sun moves through space at a speed lower than estimated so far, prevent form the bend over shock that evidently marked the border between our solar system and interstellar medium. The discovery suggests that the protective boundary that separates our solar system from the rest of the galaxy that has no bend over shock, which could have implications for how much radiation (in the form of galactic cosmic rays) coming into our solar system.

Our Solar System

Our solar system consists of its major star, the Sun and a set of body is not just about the eight planets now known, that because the August 24, 2006 the International Astronomical Union meet in Prague which was define planet or to be careful as such or the function of the sound "planet" Pluto was leaving because their individuality do not conform to what is intended by the planet, so going to be a planetoid and for that reason, our Solar System now includes nine planets, but eight, this termination is due to the amount of various bodies that have different sizes orbiting like planets around the Sun as asteroids, comets, meteoric bodies, interplanetary dust and gas, which make this set we call the solar system.

What is the Solar System?

The Solar System is a place or classification of planets orbit a common star (the Sun) which in revolve orbits virtually round method around the center of the galaxy. The 99.86% of the mass of the solar system is restricted in the Sun and most of the respite in Jupiter.

How did it?

Near are numerous theories about the configuration of our Solar System, one of which is the nebular theory:

It indicate that the solar system had formed from a nebula (cloud of gas and dust immense) that began to collapse upon itself due to gravitational forces which outnumbered own pressure forces the gases tend to that the nebula expands.
