Hubblecast Episode 40: Wide Field Camera 3 (WFC3) – Hubble’s New Miracle Camera In early 2009, a team of astronauts visited Hubble to repair the wear and tear of twenty years of operating in a hostile environment – and to install two new instruments, the Cosmic Origins Spectrograph, and Wide Field Camera 3 – better known as WFC3. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — Wide Field Camera 3 (WFC3) is a combined ultraviolet, visible and infrared camera that dramatically extends Hubble’s ability to image astronomical objects. With these new capabilities, Hubble is still pushing the boundaries of science after two decades in orbit. In episode 30 of the Hubblecast, we saw some of the very first pictures to come back from Wide Field Camera 3, Hubble’s newest and most advanced instrument. Today we’re going to look at some of the science behind these pictures. We’ll find out how this remarkable new camera is helping Hubble to see the invisible, look far back in time and spot objects further away from us than ever before. WFC3 was installed on Hubble in place of WFPC2, the Wide Field and Planetary Camera 2, which for many years had been the main workhorse instrument on Hubble. Not only do the two instruments have very similar names, and look virtually identical, the capabilities of WFC3 are also in some respects just a tweaked version of those of its predecessor — although with sharper pictures and more …

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 …

Please join us on Facebook for the latest science news and videos: tinyurl.com Hubble Space Telescope – 15 Years of Discovery (Episode 8): Birth And Death Of The Universe. In the 15 years that the NASA/ESA Hubble Space Telescope has orbited Earth, it has taken three-quarters of a million photographs of the cosmos. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — In many ways Hubble is the most successful scientific project in the World, and this event is not likely to go unnoticed. The European Space Agency, ESA, has decided to celebrate this anniversary with the production of a Hubble 15th Anniversary movie called “Hubble – 15 Years Of Discovery”. The movie covers all aspects of the Hubble Space Telescope project: a journey through the history, the trouble and the scientific successes of Hubble. This portrait of one of the biggest scientific projects of all time contains large amounts of previously unpublished footage in uncompromised quality. With the beautiful backdrop of Hubbles visual image treasures running as a red line through the movie, the light and dreaming style tells the most interesting stories about our fascinating Universe and about the change of vision that Hubble has brought us. — The Hubble Space Telescope (HST), named after Edwin Powell Hubble (1889-1953) who was one of the great pioneers of modern astronomy, is a collaboration between ESA and NASA. It is a long-term, space-based …

Hubblecast 31: Sky merger yields sparkling dividends. A recent NASA/ESA Hubble Space Telescope image captures what appears to be one very bright and bizarre galaxy, but is actually the result of a pair of spiral galaxies, like our own Milky Way smashing together at breakneck speeds. The product of this dramatic collision, called NGC 2623, or Arp 243, is about 250 million light-years away in the constellation of Cancer (the Crab). This object was a target of Hubble’s and a handful of its “sibling” spacecraft as part of a massive comprehensive sky survey called GOALS. — • www.youtube.com • www.youtube.com — Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the centre of the other, until ultimately, the two merge into one massive galaxy. The object in the image, NGC 2623, is in the late stages of the merging process with the centres of the original galaxy pair now merged into one nucleus. However, stretching out from the centre are two tidal tails of young stars showing that a merger has taken place. During such a collision, the dramatic exchange of mass and gases initiates star formation, seen here in both the tails. The prominent lower tail is richly populated with bright star clusters — 100 of them have been found in these observations. The large star clusters that the team have observed in the merged galaxy are brighter …

Science@ESA Vodcast (Episode 3, Part 1): Exploring The Infrared Universe. In the Science@ESA series Rebecca Barnes will take you on a journey of discovery into the rapidly evolving field of space astronomy and planetary exploration. — • www.youtube.com • www.youtube.com • www.youtube.com — In this third episode of the Science@ESA vodcast series we investigate the infrared Universe, explore discoveries made by ground-breaking infrared space telescopes, and take a look at Herschel – esa’s pioneering infrared space telescope. Herschel, esa’s cutting-edge space observatory, will carry the largest, most powerful infrared telescope ever flown in space. A pioneering mission to study the origin and evolution of stars and galaxies, it will help understand how the Universe came to be what it is today. The first observatory to cover the entire range from far-infrared to sub-millimetre wavelengths and bridge the two, Herschel will explore further in the far-infrared than any previous mission, studying otherwise invisible dusty and cold regions of the cosmos, both near and far. Herschel will tap into unexploited wavelengths, seeing phenomena out of reach for other observatories, at a level of detail that has not been captured before. The telescope’s primary mirror is 3.5 m in diameter, more than four times larger than any previous infrared space telescope and almost one and a half times larger than that of the Hubble Space Telescope. The telescope will collect almost twenty times …

NASA Astronomy Pictures Of The Day [Week 2/2010]. — • www.youtube.com • www.youtube.com — ? The Spider and The Fly Bright clusters and nebulae abound in the ancient northern constellation of Auriga. The region includes the open star cluster M38, emission nebula IC 410 with Tadpoles, Auriga’s own Flaming Star Nebula IC 405, and this interesting pair IC 417 (lower left) and NGC 1931. An imaginative eye toward the expansive IC 417 and diminutive NGC 1931 suggests a cosmic spider and fly. About 10000 light-years distant, both represent young, open star clusters formed in interstellar clouds and still embedded in glowing hydrogen gas. • Learn more: antwrp.gsfc.nasa.gov ?
