... December 23, 1998 . Ring Around the Galaxy . ... Explanation: It is difficult to hide one galaxy far behind another. The closer galaxy's gravity will act like a huge lens , pulling images of the background galaxy around both sides. This is just the case observed in the above recently released image from the VLT : the red galaxy in the middle is in the foreground, lensing the image of the background green galaxy into surrounding contorted arcs . ...

... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

... 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. ...

... Gravity is responsible for keeping your feet on the ground and keeping the Earth and all other planets in our Solar System in their orbits around the Sun. ... Einstein's theory of gravity, known as the theory of General Relativity. This suggested that gravity is actually the curving of the fabric of the Universe, known as 'spacetime', around objects. For instance, a very heavy star warps the space around it, causing a deep well in the fabric, and pulling in anything that comes too close. ...

X-ray Binaries . Image of a normal star and a neutron star . The neutron star's gravity pulls matter from the normal star in this binary star system. The matter swirls around the neutron star because it cannot hold the matter at the rate it is flowing towards it. The neutron star locks the matter by means of gravity and therefore it orbits around the neutron star. ... The binary star system with one normal star and one black hole .
