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 …

From the discovery of Sedna, a distant object rotating with puzzling slowness, to theories about the death of the universe based on observation of supernova remnants, 2004 was a big year for Hubble science. This third installment in the Hubble yearbook series covers these topics and more. From HubbleSite

Movie from the paper “Observing Supernova 1987A with the Refurbished Hubble Space Telescope,” by Kevin France, Richard McCray, Kevin Heng, Robert P. Kirshner, Peter Challis, Patrice Bouchet, Arlin Crotts, Eli Dwek, Claes Fransson, Peter M. Garnavich, Josefin Larsson, Stephen S. Lawrence, Peter Lundqvist, Nino Panagia, Chun SJ Pun, Nathan Smith, Jesper Sollerman, George Sonneborn, John T. Stocke, Lifan Wang, J. Craig Wheeler. Published in Science, 7 September 2010. dx.doi.org Supporting Online Material. “This movie displays the evolution of the remnant of SN1987A as observed by the Hubble Space Telescope. The rapidly fading and expanding central source is light from the inner radioactive supernova debris. The inner circumstellar ring is glowing initially because it was ionized by radiation from the supernova outburst. At about 1995, the first hotspot appeared at approximately 11 o’clock. Today, the ring is entirely encircled by hotspots. The radiation from the hotspots is caused by compression and heating that takes place when the supernova blast wave enters.” Abstract: “Observations with the Hubble Space Telescope (HST), conducted since 1990, now offer an unprecedented glimpse into fast astrophysical shocks in the young remnant of supernova 1987A. Comparing observations taken in 2010 using the refurbished instruments on HST with data taken in 2004, just before the Space Telescope Imaging Spectrograph failed, we find that the Ly and H lines from shock emission continue to …

Hubblecast 26: Exceptionally Deep View Of Strange Galaxy. A spectacular new image of an unusual spiral galaxy in the Coma Galaxy Cluster has been created from data taken by the Advanced Camera for Surveys on the NASA/ESA Hubble Space Telescope. It reveals lots of new details of the galaxy, NGC 4921, as well as an extraordinary rich background of more remote galaxies stretching back to the early Universe. — Subscribe to Science & Reason: • www.YouTube.com • www.YouTube.com • www.YouTube.com • www.YouTube.com — Credits: • ESA/Hubble (M.
