http://www.SupremeMasterTV.com Astronomers have taken an image of a solar system outside our own and a photograph of a new planet. It's a profound and overwhelming experience to lay eyes on a planet never before seen. We look forward to additional new findings about our extraordinary universe....etc.天文學家拍攝到其他太陽系的影像及一顆新行星的照片，看到未曾見過的行星這種經驗很深刻且令人震撼，我們期望從非凡的宇宙能找到更多新發現等等。 |

The First-Ever Photo of 3 Extrasolar Planets (Nov.13, 2008)
|
11/13/2008. This is the first time planets have been observed orbiting a distant star, as opposed to just photographed near such stars.
The research team, led by astronomer Dr. Christian Marois of the National Research Council Canada/Herzberg Institute of Astrophysics, used advanced instrumentation and image-processing techniques to detect the three faint planets against the bright glare of their host star. The images were captured by the Gemini North and Keck telescopes at the Mauna Kea Observatories in Hawaii.

Extrasolar Planet
|
After years of suspecting the existence of planets in other solar systems in the universe, the Hubble Space Telescope captures visible-light images that, for the first time ever, provide concrete evidence of these extrasolar planets. |

Organic molecules found by Hubble on extrasolar planet
|
NASA press release:
NASA's Hubble Space Telescope (HST) has made the first detection ever of an organic molecule in the atmosphere of a Jupiter-sized planet orbiting another star. This breakthrough is an important step in eventually identifying signs of life on a planet outside our solar system.
The molecule found by Hubble is methane, which under the right circumstances can play a key role in prebiotic chemistry — the chemical reactions considered necessary to form life as we know it.
This discovery proves that Hubble and upcoming space missions, such as NASA's James Webb Space Telescope, can detect organic molecules on planets around other stars by using spectroscopy, which splits light into its components to reveal the "fingerprints" of various chemicals.
"This is a crucial stepping stone to eventually characterizing prebiotic molecules on planets where life could exist," said Mark Swain of NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif., who led the team that made the discovery. Swain is lead author of a paper appearing in the March 20 issue of Nature.
The discovery comes after extensive observations made in May 2007 with Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS). It also confirms the existence of water molecules in the planet's atmosphere, a discovery made originally by NASA's Spitzer Space Telescope in 2007. "With this observation there is no question whether there is water or not — water is present," said Swain.
The planet now known to have methane and water is located 63 light-years away in the constellation Vulpecula. Called HD 189733b, the planet is so massive and so hot it is considered an unlikely host for life. HD 189733b, dubbed a "hot Jupiter," is so close to its parent star it takes just over two days to complete an orbit. These objects are the size of Jupiter but orbit closer to their stars than the tiny innermost planet Mercury in our solar system. HD 189733b's atmosphere swelters at 1,700 degrees Fahrenheit, about the same temperature as the melting point of silver.
Though the star-hugger planet is too hot for life as we know it, "this observation is proof that spectroscopy can eventually be done on a cooler and potentially habitable Earth-sized planet orbiting a dimmer red dwarf--type star," Swain said. The ultimate goal of studies like these is to identify prebiotic molecules in the atmospheres of planets in the "habitable zones" around other stars, where temperatures are right for water to remain liquid rather than freeze or evaporate away.
The observations were made as the planet HD 189733b passed in front of its parent star in what astronomers call a transit. As the light from the star passed briefly through the atmosphere along the edge of the planet, the gases in the atmosphere imprinted their unique signatures on the starlight from the star HD 189733.
The astronomers were surprised to find that the planet has more methane than predicted by conventional models for "hot Jupiters." "This indicates we don't really understand exoplanet atmospheres yet," said Swain.
"These measurements are an important step to our ultimate goal of determining the conditions, such as temperature, pressure, winds, clouds, etc., and the chemistry on planets where life could exist. Infrared spectroscopy is really the key to these studies because it is best matched to detecting molecules," said Swain. |

Extrasolar Planet's Atmosphere Evaporating into Space
|
Using the Hubble Space Telescope, for the first time, astronomers have observed the atmosphere of an extrasolar planet evaporating off into space. Much of this planet may eventually disappear, leaving only a dense core. The planet is a type of extrasolar planet known as a 'hot Jupiter'. These giant, gaseous planets orbit their stars very closely, drawn to them like moths to a flame.
