... Exoplanets . ... Artists impression of the blue exoplanet. ... This exoplanet is located in the constellation of Vulpecula, the fox, a faint pattern inside the Summer Triangle.ТљТљ This planet is a not too distant 63 light years away so has been studied by space-based telescopes.Тљ Data collected from Hubbleт??s Imaging Spectrograph (STIS) when this planet moved behind its star showed that in the shadow of the star the light reflected from HD 189733b reduced into the blue part of the spectrum. ...

... Explanation: This planet is only 16 light years away -- could it harbor life? ... An interesting coincidence, however, is that Gliese 832c receives just about the same average energy from its parent star as does the Earth. ... If Gliese 832c has an atmosphere like Earth, it may be a super-Earth undergoing strong seasons but capable of supporting life. ... The close 16-light year distance makes the Gliese 832 planetary system currently the nearest to Earth that could potentially support life. ...

... 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. ...

... 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. ...

... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth. During a recent investigation by an international group of astronomers [1], the best picture ever of Pluto and Charon [2] was secured with the European Space Agency's Faint Object Camera at the Hubble Space Telescope (HST). ... The new HST image was taken when Charon was near its maximum elongation from Pluto (0.9 arcseconds). ...

... Bad Astronomy . ... Bitesize Astronomy . ... If you thought our tour of the solar system ended with Neptune and Pluto, you are setting your sights way too low. The planets of the solar system mark time relatively close to the Sun compared to interstellar space. Pluto orbits the Sun at an average distance 40 times that of the Earth, yet the nearest star (the Alpha Centauri system) to the solar system is a mind-numbing 260,000 times the distance of the Earth to the Sun. ... 2008 Phil Plait. ...

Microsymposium 38, MS083, 2003 (A4 format) MERCURY: LOCAL VARIATIONS OF THE PHOTOMETRIC RELIEF. ... Because of trajectory and pointing angle constraints the planet could be observed from Mariner 10 only over a small range of phase angles between about 75o and 110o. Therefore the photometric investigations are restricted to measuring the distribution of brightness on the Mercurian disk. ...
