The discovery of a Jupiter -like planet in a Jupiter-like orbit around nearby Sun -like star 55 Cancri , announced yesterday, gives a new indication that planetary systems similar to our Solar System likely exist elsewhere. The planet, discovered by G. Marcy ( UC Berkeley ) and collaborators, is one of two new planets found around 55 Cancri -- in 1997 a Jupiter-massed planet was found orbiting very close in. ...

The Discovery of the Galilean Satellites . ... Probably the most significent contribution that Galileo Galilei made to science was the discovery of the four satellites around Jupiter that are now named in his honor. Galileo first observed the moons of Jupiter on January 7, 1610 through a homemade telescope. He originally thought he saw three stars near Jupiter, strung out in a line through the planet. ...

Armagh Observatory, 24 July 2000: . The Minor Planet Center at the Smithsonian Astrophysical Observatory, Cambridge, Massachusetts, USA, has announced the discovery of a new moon of Jupiter, bringing to 17 the number of known satellites orbiting the giant planet. ... At that time, Jupiter was about 370 million miles from Earth, just about as close as it ever gets, and therefore a good time to search for any faint satellites. ... Last Revised: 10th August 2000 . ...

... Many massive planets contrary to Jupiter have large eccentricities of orbits. ... Another problem is to study the conditions and boundaries of stable, regular motions of small mass planet in systems having `Jupiter' with large orbital eccentricity as well as properties of regular, stable, and irregular, chaotic motions. ... The regular eccentricity evolution described above demonstrates that stable quasi--circular orbits of small planet are unusual. ...

A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ...

Now that well over 100 planets have been discovered, we no longer need to ask the question "Are there planets out there?" ... The objective of XO is to find additional hot-Jupiters (like HD 209458b) that transit stars bright enough for detailed follow-up studies to be done with existing telescopes such as HST, Keck, and the VLT. ... Transit observations by themselves provide no information about the mass of the planet and radial velocity studies can yield only minimum masses. ...

... 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. ...
