1. http://www.eso.org/public/news/eso1241/kids/
... Astronomers have found a planet the size of Earth just outside of our Solar System, orbiting around our nearest star! ... More than 800 planets have now been found outside our Solar System, we call them 'exo-planets . ... While the newly discovered exo-planet is similar to the Earth in size, it is much closer to its star than our planet. ... A year on the exo-planet would be just three days long (this is how long it takes the planet to complete one orbit of its star). ...

2. Kepler-10c: the First Mega-Earth | Astronotes
... Planets . ... Earth Satellites . ... The newly discovered ?mega-Earth? ... Its sibling, the lava world Kepler-10b, is in the background (the two planets? proximity is grossly exaggerated) .€а Kepler-10c has a diameter of about 29 000 km, 2.3 times as large as Earth, and weighs 17 times as much. ... The first mega-earth to be discovered is Kepler-10c which orbits a star lying about 560 light years from the Sun in the constellation Draco. ...

3. ASP: Miranda: A Jigsaw Puzzle World
... When the Voyager 2 spacecraft flew by the planet Uranus in January 1986, astronomers were treated to their first close-up glimpse of the satellites that orbit the seventh planet. ... But by far the most intriguing of those 15 satellites was a jigsaw-puzzle world called Miranda . ... How dark was it at Miranda? One of the Voyager scientists put it this way: Taking pictures in the Uranus system is like trying to do photography in a ballpark at night when the only light comes from a single candle. ...

... STScI-PRC99-27 A CLOSER ENCOUNTER WITH MARS Taking advantage of Mars's closest approach to Earth in eight years, astronomers using NASA's Hubble Space Telescope have taken the space-based observatory's sharpest views yet of the Red Planet. ... In these views the north polar cap is tilted toward the Earth and is visible prominently at the top of each picture. ... Dark sand dunes that surround the polar cap merge into a large, dark region called Acidalia. ...

5. GALILEO READY FOR CLOSE FLYBY OF JUPITER'S BIGGEST MOON
NASA Press Release Text - June 24, 1996 GALILEO READY FOR CLOSE FLYBY OF JUPITER'S BIGGEST MOON Now residing in orbit around Jupiter, NASA's Galileo spacecraft is primed for its first close flyby of Jupiter's largest moon, Ganymede, at 2:29 a.m. EDT on June 27, 1996. ... In the days just before and after the Ganymede flyby, Galileo's other studies will include a search for auroral activity on Jupiter's nightside and observations of other Jovian moons: Io, Europa and Callisto. ...

6. Phil Plait's Bad Astronomy: Bitesize Astronomy
... Bad Astronomy . ... Bitesize Astronomy . ... Keep Bad Astronomy close to your heart, and help make me filthy rich. ... It's semi-common knowledge that stars twinkle and planets don't. By semi-common, I mean that a lot of folks know that, but I also mean it isn't strictly true. Stars twinkle because we see them from the bottom of a sea of air. ... These small bundles of air act like little lenses, bending light as it passes through them. ... What we see is the light from the star flickering. ...

7. http://zebu.uoregon.edu/51peg.html
... 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. ...

8. Mercury
... M ercury is the closest planet to the Sun and the eighth largest. ... Heraclitus even believed that Mercury and Venus orbit the Sun, not the Earth. ... The perihelion of its orbit precesses around the Sun at a very slow rate. 19th century astronomers made very careful observations of Mercury's orbital parameters but could not adequately explain them using Newtonian mechanics. ... Actually Earth's density is due in part to gravitational compression; if not for this, Mercury would be denser than Earth...

9. Armagh Astropark: Comets
... Solar System . ... Sun . ... Comets . ... Some get thrown out of the solar system forever, whereas others end up on yet smaller orbits, visiting the inner solar system fairly frequently - such as comet Halley. ... When a comet moves into the inner solar system, this is heated by the Sun, and the ices turn into gas which forms the head or coma of the comet, which may be hundreds of thousands of kilometres across and visible from Earth. The most striking part of many active comets is the tail . ...

... Crescent Moon Meets Evening Star . ... Stars and Dust Across Corona Australis . ... Cosmic dust clouds sprawl across a rich field of stars in this sweeping telescopic vista near the northern boundary of Corona Australis, the Southern Crown. Less than 500 light-years away the dust clouds effectively block light from more distant background stars in the Milky Way. ... Actually, given how close Gliese 1214b is to its parent star, any water, if it exists, would surely be in the form of steam. ...

11. http://www.stsci.edu/stsci/meetings/planets/abs/prog21.html
... The planet in orbit around 51 Peg has, according to theoretical models, moved into its current position from farther away and its atmosphere may therefore be strongly evaporating. The molecules released by the upper parts of the atmosphere must be rapidly ionized and could form an envelope around the planet. If the planet passes in front of the star, this envelope is in favorable geometric conditions (the inclination angle of the orbit is close to 90?) which allow it to occult the star. ...

12. The Scale of the Solar System
... 9a. Earth orbits Sun? . ... 10a. Scale of Solar Sys. ... If the mean distance of Earth from the Sun is 1 AU ("Astronomical Unit"), then that of Venus is 0.723 AU, of Mercury 0.387 AU and that of Mars is 1.524 AU. ... By noting (1) where on the Sun's disk is the crossing seen, (2) timing its duration at two far-apart points on Earth, and (3) comparing the times, one can calculate the distance to Venus and from it the scale of the solar system. ... One occurred in 1639--too early. ...

. This artistтАЩs impression shows the surface of the distant dwarf planet Makemake. This dwarf planet is about two-thirds of the size of Pluto and travels around the Sun in a distant path that lies beyond that of Pluto, but closer to the Sun than Eris, the most massive known dwarf planet in the solar system. Scientists expected Makemake to have an atmosphere like Pluto, but this has now been shown to not be the case. // Credit: ESO/L. Cal†зada/Nick Risinger

17. The Russian TESIS Observatory will observe two solar eclipses from space
... This year's eclipse is unique in duration. ... Although, at the present time, there are 6 solar observatories belonging to leading space agencies in orbit around the Earth, the eclipse of 22 July, 2009, will only be seen by two of them: the Russian CORONAS-PHOTON satellite equipped with TESIS telescopes and Japan's HINODE satellite fitted with an XRT space telescope. ... TESIS will be the first of the two devices (and the very first on Earth) to witness the solar eclipse. ...
