First Image of an Alien Planet

http://news.bbc.co.uk/2/hi/science/nature/7725584.stm Exoplanets finally come into view Three exoplanets (NRC-HIA/ IDPS/ Keck) Three exoplanets orbiting the same star have been imaged directly The first pictures of planets outside our Solar System have been taken, two groups report in the journal Science. Visible and infrared images have been snapped of a planet orbiting a star 25 light-years away. The planet is believed to be the coolest, lowest-mass object ever seen outside our own solar neighbourhood. In a separate study, an exoplanetary system, comprising three planets, has been directly imaged, circling a star in the constellation Pegasus. While several claims have been made to such direct detection before, they have later been proven wrong or await confirmation. It's a profound and overwhelming experience to lay eyes on a planet never before seen Paul Kalas, University of California The search for exoplanets has up to now depended on detecting either the wobble they induce in their parent star or, if their orbits are side-on to telescopes, watching them dim the star's light as they pass in front of it. Being able to directly detect the light from these planets will allow astronomers to study their composition and atmospheres in detail. Ring cleaning The difficulty for astronomers imaging exoplanets is that their parent star's light swamps them - like trying to spot a match next to a floodlight at a distance of a mile. The light from the star Fomalhaut was blocked to spot the planet Enlarge Image But advances in optics and image processing have allowed astronomers to effectively subtract the bright light from stars, leaving behind light from the planets. That light can either come in the infrared, caused by the planets' heat, or be reflected starlight. Paul Kalas of the University of California, Berkeley, led an international group that used the Hubble Space Telescope to image the region around a star called Fomalhaut in the constellation Piscis Austrinus. The star has a massive ring of dust surrounding it that appears to have a cleanly groomed inner edge. That is in keeping with what is known as accretion theory - that young planets gather up dust and matter as they orbit - and prompted the team to begin looking for the suspected planet in 2005. The team estimates that the planet, designated Fomalhaut b, is some 18 billion kilometres (11 billion miles) away from its star, about as massive as Jupiter and completes an orbit in about 870 years. It may also have a ring around it. "I nearly had a heart attack at the end of May when I confirmed that Fomalhaut b orbits its parent star," Dr Kalas said. "It's a profound and overwhelming experience to lay eyes on a planet never before seen." An artist's concept of the star Fomalhaut and the planet observed by Hubble Christian Marois of the Herzberg Institute for Astrophysics, Canada, and his team used the Keck and Gemini telescopes in Hawaii to look near a star called HR 8799, which is just visible to the naked eye. The team studied light in the infrared part of the spectrum, hoping to spot planets that were still hot from their formation. What they found in 2004, and confirmed again this year, are three planets circling the star. According to a theoretical model that accounts for the light coming from the planets, they range in size from five to 13 times the mass of Jupiter and are probably only about 60 million years old. The trio have similarities with our own Solar System. Their orbits are comparable in size to those of the outer planets, and the smaller planets are those closest to the Sun - again suggesting a system that formed through accretion. Dr Marois points out that the current methods used in the exoplanet hunt are sensitive primarily to Jupiter-sized planets and larger. "We thus do not have a full picture," he told BBC News. "The detection of the three planets around HR 8799 does not mean that no planets are orbiting at smaller separations. Other gas giant or even rocky planets could reside there." Comparison - inner four planets in our system not shown; Dwarf planet Pluto included to help see scale (C. Marois/NRC) A to-scale comparison of the HR 8799 system and our own The study of the light directly from the planets will yield information about their atmospheres and surfaces that is impossible to collect from planets discovered indirectly. Further, the current results will also support theories of how planets form from the grand discs of dust and material around stars, and lead to better estimates of how many Earth-like planets are likely to exist. These latest claims are both based on observations that were well-spaced in time, allowing the researchers to apply a rigorous test for direct detection. "You see an object next to a star and you might think it's a planet," commented Mark McCaughrean, an astrophysicist at the University of Exeter, UK. "But you have to watch it for several years and make sure that it moves around the star and with the star as it moves across the sky. Though I've been very sceptical in the past, these ones all seem pretty real to me," he told BBC News "It's like a London bus - you've been waiting for one for ages and suddenly four come along at once." Hubble Space Telescope does it again, from ESA's "Hubblecast." Category: Science & Technology

Universe 114 Beyond Big Bang 47 Galileo

The History Channel Australia & New Zealand The Universe : 1/14 Beyond The Big Bang : 4/7 Galileo Learn about Galileo's bold moves of challenging the church with his theories of the universe. --- It all began inside a violent, blinding explosion that threw everything into chaos. Ever since, our greatest thinkers have peered into that chaos in search of order, logic & the answers to where we began. As earlier generations learned to decipher the cosmic clues of how we came to be, we stepped from revelation to revelation; epiphany to epiphany. Aristotle told us the world was round. Ptolemy conceived of a system of planets, stars & sun. Copernicus placed the sun at the center of this system. Galileo confirmed it. Newton explained what held it all together. Einstein offered insight into what fueled it. Hubble proposed it started with a "Big Bang". Our search for answers has shaped how we have evolved as thinking creatures. The Big Bang is the history of why & how we think about who & what we are. We'll contemplate how various cultures believe the world began & how it will all end...& what comes after. & for the first time, we'll be able to see what it might have all looked like, sitting in God's front row seats. Using unprecedented cutting edge animation, The Big Bang will recreate that amazing moment when everything started. With interviews from the world's leading physicists, engineers & historians we will employ every storytelling tool to make complex & confusing ideas clear, exciting & dramatic. Recreations, visual metaphors & first-person accounts will explain concepts like: the formation of galaxies, the existence of other dimensions & the idea of a parallel universe. The Big Bang will pose one of history's greatest questions, Where do we begin? --- http://www.thehistorychannel.com.au

Interview with Galileo

15 February 1564 -- 8 January 1642 was a Tuscan (Italian) physicist, mathematician, astronomer, and philosopher who played a major role in the scientific revolution. His achievements include the first systematic studies of uniformly accelerated motion, improvements to the telescope and consequent astronomical observations, and support for Copernicanism. Galileo's empirical work was a significant break from the abstract Aristotelian approach of his time. Galileo has been called the "father of modern observational astronomy", the "father of modern physics", the "father of science", and "the Father of Modern Science." The motion of uniformly accelerated objects, taught in nearly all high school and introductory college physics courses, was studied by Galileo as the subject of kinematics. His contributions to observational astronomy include the discovery of the four largest satellites of Jupiter, named the Galilean moons in his honour, and the observation and analysis of sunspots. Galileo also worked in applied science and technology, improving compass design. Galileo's championing of Copernicanism was controversial within his lifetime. The geocentric view had been dominant since the time of Aristotle, and the controversy engendered by Galileo's opposition to this view resulted in the Catholic Church's prohibiting the advocacy of heliocentrism as potentially factual, because that theory had no decisive proof and was contrary to the literal meaning of Scripture. Galileo was eventually forced to recant his heliocentrism and spent the last years of his life under house arrest on orders of the Inquisition.

Pope Bans Copernicus Theory of Sun-Centered Universe

The Catholic Church listed Copernicus' "De revolutionibus" on its Index of Prohibited Books, thus prohibiting its publication and denying the physical reality of the earth's movement around the sun. Andreas Cellarius circumvented the ban by depicting the theory in the lavish and ingenious drawings of "Harmonia macrocosmica", the most beautiful and famous Celestial Atlas.

Core Astronomy - Quasars

The advancements in radio telescope technology lead to the discovery of quasars. Core Astronomy examines the key points in the development of astronomy, beginning with Greek astronomer Ptolemy's earth centered paradigm to Nicolas Copernicus' introduction of a sun centered solar system, and Isaac Newton's three laws of motion. It then examines the discovery of Neptune, Einstein's theories of Special and General Relativity, Hubble's expanding universe, and the discoveries of quasars, white dwarfs, neutron stars, pulsars and black holes, and finally ends with astronomy's modern frontiers - the great attractor, dark matter and life existing on an extrasolar planet Buy it now: http://www.ambrosevideo.com/displayitem.cfm?vid=1233

Cowboy Bebop OST 4 - What planet is this!

Web: http://radiomanga.blogspot.com http://ostanimemusic.blogspot.com What planet is this! Anime: Cowboy Bebop OST: Cowboy Bebop OST 4 Knockin' on Heaven's Door (1998) [audio] Cowboy Bebop (カウボーイビバップ, Kaubōi Bibappu) is a Japanese animated television series. Directed by Shinichiro Watanabe and written by Keiko Nobumoto, Cowboy Bebop was produced by Sunrise. Consisting of 26 episodes, the series follows the adventures of a group of bounty hunters traveling on their spaceship, the Bebop, in the year 2071. Cowboy Bebop was a commercial success both in Japan and international markets, notably in the United States. After this reception, Sony Pictures released a feature film, Knockin' on Heaven's Door to theaters worldwide and followed up with an international DVD release. Two manga adaptations were serialized in Kadokawa Shoten's Asuka Fantasy DX. Cowboy Bebop has been strongly influenced by American music, especially the jazz movements of the 1940s, 1950s and 1960s and the early rock era of the 1950s, 1960s and 1970s. Many of its action sequences, from space battles to hand-to-hand martial arts combat, are set and timed to music. Following the musical theme, episodes are called Sessions, and titles are often borrowed from album or song names (such as Sympathy for the Devil or My Funny Valentine), or make use of a genre name ("Mushroom Samba") indicating a given episode's musical theme.
