Hubblecast 41: Hubble’s History Told by Hubble’s Scientists Hubble’s history of scientific breakthroughs has made us think afresh about our Universe. But behind the astronomical successes is a rollercoaster ride of scientific and technical challenges going back decades. The Hubblecast caught up with some of the key players in Hubble’s history, including an astronaut, a Nobel Prize winner and one of the scientists who diagnosed Hubble’s blurred vision in 1990. In this episode, narrated by veteran ESA scientist Bob Fosbury, they tell Hubble’s story through their personal experiences. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — Venice is just a few centimetres above sea level, about as far from space as you can get. But in 1609, Galileo Galilei brought this city a bit closer to the stars when he gave one of the very first demonstrations of his telescope. A few months after that, he discovered Jupiter’s moons, Io, Ganymede, Callisto and Europa. Four centuries later, another telescope is making history here, as scientists gather to discuss the latest results from Hubble. Hubble was launched in 1990. And that’s of course when its history of scientific discoveries starts. But Hubble’s history isn’t just about science and technology. Like Galileo’s story, it’s also one of politics, money … and extremely smart people doing very difficult things. Bob O’Dell: “I became the first project scientist for the …

Eclipse over the Temple of Poseidon The Moon moved to partly block the Sun for a few minutes last week as a partial solar eclipse became momentarily visible across part of planet Earth. In the above single exposure image, meticulous planning enabled careful photographers to capture the partially eclipsed Sun well posed just above the ancient ruins of the Temple of Poseidon in Sounio, Greece. • antwrp.gsfc.nasa.gov ? Dust Sculptures in the Rosette Nebula Noted for the common beauty of its overall shape, parts of the Rosette Nebula, also known as NGC 2237, show beauty even when viewed up close. Visible above are globules of dark dust and gas that are slowly being eroded away by the energetic light and winds by nearby massive stars. Left alone long enough, the molecular-cloud globules would likely form stars and planets. The Rosette Nebula spans about 50 light-years across and lies about 4500 light-years away. • antwrp.gsfc.nasa.gov ? Watch Jupiter Rotate What would it be like to coast by Jupiter and watch it rotate? This was just the experience of the New Horizons spacecraft as it approached and flew by Jupiter. Visible above in the extensive atmosphere of the Solar System’s largest planet are bands and belts of light and dark clouds, as well as giant rotating …

Science & Reason on Facebook: tinyurl.com The Hidden Universe (Episode 20): Cassiopeia A – Echoes of a Supernova A supernova flash echoing through surrounding dust clouds has given astronomers a virtual time machine for studying the light from the explosion that nobody saw. This is the Hidden Universe of NASA’s Spitzer Space Telescope, exploring the mysteries of infrared astronomy with your host Dr. Robert Hurt. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — It’s the 17th century supernova that nobody saw, but telescopes in space and on Earth have teamed up to look back in time and study it today! When a massive star reaches its end of days it explodes dramatically and, for a few months, can outshine anything else in the galaxy. Earlier supernovas had been seen by many, often shining brighter than the planets. Of course with no witnesses, and no records, it’s difficult to tell exactly what kind of supernova it was. A team led by astronomer Oliver Krause has, over the last few years, made a remarkable series of infrared observations of the region. These Spitzer Space Telescope images show shifting patterns of glowing dust beyond the remnant itself. These changes are so fast that they indicate motion at the speed of light! To get what’s happening we have to remember that light moves fast, but in such a vast galaxy it still takes a while for it to get anywhere. Cassiopeia A (Cas A) itself is about 11000 …

Science & Reason on Facebook: tinyurl.com “The Andromeda Galaxy” with Jane Houston Jones at NASA’s Jet Propulsion Laboratory in Pasadena, California. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — The Andromeda Galaxy (also known as Messier 31, M31, or NGC 224) is a spiral galaxy approximately 2500000 light-years away in the constellation Andromeda. It is the nearest spiral galaxy to our own, the Milky Way. As it is visible as a faint smudge on a moonless night, it is one of the farthest objects visible to the naked eye, and can be seen even from urban areas with binoculars. It is named after the princess Andromeda (Greek: ????????? Androméd?) in Greek mythology. Andromeda is the largest galaxy of the Local Group, which consists of the Andromeda Galaxy, the Milky Way Galaxy, the Triangulum Galaxy, and about 30 other smaller galaxies. Although the largest, Andromeda may not be the most massive, as recent findings suggest that the Milky Way contains more dark matter and may be the most massive in the grouping. The 2006 observations by the Spitzer Space Telescope revealed that M31 contains one trillion stars, several times more than the number of stars in our own galaxy, which is estimated to be c. 200-400 billion. While the 2006 estimates put the mass of the Milky Way to be ~80% of the mass of Andromeda, which is estimated to be 7.1 × 1011 solar masses, a 2009 study concluded that Andromeda and the Milky …

Science & Reason on Facebook: tinyurl.com ESOcast 13: A sharper view of the Universe with the VLT Interferometer. In principle, the larger a telescopes mirror, the finer the details it can see. Continuing to increase the size of telescope mirrors is not an easy task, so astronomers have come up with a new technology to see even finer details: interferometry. This observational technique combines the light received by two or more telescopes and allows them to act as a single unit with a mirror diameter equivalent to the distance between the telescopes. Engineers designed the VLT so that it can also be used as an interferometer. Along with the four 8.2-metre Unit Telescopes, four mobile 1.8-metre Auxiliary Telescopes (ATs) were included in the overall VLT concept to form the Very Large Telescope Interferometer (VLTI). The ATs can move between 30 different stations, and at present, the telescopes can form groups of two or three for interferometry. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — Imagine looking up at the night sky and seeing details on the surface of a star millions of millions of kilometres away. Imagine having eyesight so keen that you could check out the surroundings of a black hole. Using ESOs Very Large Telescope Interferometer at Paranal, astronomers are now making these fantasies a reality. Each of the four VLT Unit Telescopes has a primary mirror with a diameter of 8.2 metres. Such …

Please join us on Facebook for the latest science news and videos: tinyurl.com Cosmic Visions: New ESA Space Science Missions Move Forward. Under its Cosmic Vision initiative, the European Space Agency has selected three medium-sized science missions to enter the definition phase. Spacecraft to study dark energy, Earth-like exoplanets and our own Sun now have to prove that they can be built within the allocated budgets. 2011, just two of them will be retained to go forward for launches no earlier than 2017. This movie describes the three missions Euclid, Plato and Solar Orbiter. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — Since the early ’60s, ESA has excelled in pushing back the frontiers in space science: exploring the nearest planets and the most distant celestial bodies of our solar system; lifting the veil with powerful telescopes on galaxy and star formation and probing the most violent processes in the Universe; and better understanding its evolution since the Big Bang. The three selected missions are the finalists from some 50 proposals which were whittled down to just six in late 2007 and submitted for industrial assessment. In February, the Agency’s Science Programme Committee pared down the choice once more. The project called Euclid will investigate key issues in physics, cosmology and general relativity. Until about 30 years ago astronomers thought the Universe was composed of ordinary …
