Looking in the direction of the constellation Cygnus the Swan and launched by NASA in 2009 is the Kepler Space Observatory.Many previous missions searching for exoplanets mainly detected large giant planets, like large hot Jupiters (it is easier to detect larger planets).However KeplerтАЩs main objective is to search for much smaller planets located in a habitable zone which is not too close nor too far from their star; planets which may be just like our Earth. ...

Different regimes of gravitational lensing depend on masses of lens and correspond roughly an angular distance between images. If a gravitational lens has a typical stellar mass, this regime is named as microlensing because a typical angular distance between images is about microarcseconds in the case if sources and lenses are located at cosmological distances. ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

... Over the past 16 years, astronomers have found more than 700 planets outside of our Solar System. We call these distant worlds exo-planets . ... For example, they can observe how a star dims when a planet passes in front of it. ... In this new method, astronomers use stars like magnifying glasses! ... And astronomers can tell if the star that is acting like a magnifying glass has a planet in orbit around it, as the power of the magnification is even greater! ...

Just beyond the main asteroid belt there exists a population of small objects orbiting the Sun at the same heliocentric distance of Jupiter. The combined action of Jovian and Solar gravity creates a stable dynamical haven for these objects near the so-called Lagrangian equilibrium points, in honour to the French mathematician Joseph Louis Lagrange who first demonstrated their existence and stability. ... Soon after its discovery it was realized that this asteroid is, in fact, a Mars Trojan. ...
