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.

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 …

A Roll Cloud Over Uruguay These rare long clouds may form near advancing cold fronts. In particular, a downdraft from an advancing storm front can cause moist warm air to rise, cool below its dew point, and so form a cloud. When this happens uniformly along an extended front, a roll cloud may form. Roll clouds may actually have air circulating along the long horizontal axis of the cloud. A roll cloud is not thought to be able to morph into a tornado. • Learn more: antwrp.gsfc.nasa.gov ? The Spotty Surface of Betelgeuse Betelgeuse really is a big star. If placed at the center of our Solar System it would extend to the orbit of Jupiter. But like all stars except the Sun, the red supergiant is so distant it usually appears as a single point of light, even in large telescopes. The intriguing picture shows two, large, bright, star spots. The spots potentially represent enormous convective cells rising from below the supergiant’s surface. They are bright because they’re hotter than the rest of the surface, but both spots and surface are cooler than the Sun. Betelgeuse is about 600 light-years away. • Learn more: antwrp.gsfc.nasa.gov ?

NASA’s Spitzer Science Center: “Ask An Astronomer (Part 2) Where Stars Are Born – W-5 Star-Forming Region”. In this popular video series, real astronomers answer common questions about astronomy. Brought to you by the “Cool Cosmos” team (the joint Education and Public Outreach group for the Spitzer Space Telescope and the Infrared Processing and Analysis Center) located at the California Institute of Technology in Pasadena, California. Narrated by Dr. Robert Hurt of NASA’s Spitzer Science Center. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com — How do stars form? A study of star forming region W5 by the sun-orbiting Spitzer Space Telescope provides clear clues by recording that massive stars near the center of empty cavities are older than stars near the edges. A likely reason for this is that the older stars in the center are actually triggering the formation of the younger edge stars. The triggered star formation occurs when hot outflowing gas compresses cooler gas into knots dense enough to gravitationally contract into stars. Spectacular pillars, left slowly evaporating from the hot outflowing gas, provide further visual clues. In the above scientifically-colored infrared image, red indicates heated dust, while white and green indicate particularly dense gas clouds. W5 is also known as IC 1848, and together with IC 1805 form a complex region of star formation popularly dubbed the Heart and Soul Nebulas. W5 lies about …

Life Beyond Earth: Origin And Evolution Of Life In The Universe – Best Of Carl Sagan’s Cosmos (Part 20). Carl Edward Sagan, Ph.D. (1934-1996) was an American astronomer, astrochemist, author, and highly successful popularizer of astronomy, astrophysics and other natural sciences. He pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI). He is world-famous for writing popular science books and for co-writing and presenting the award-winning 1980 television series “Cosmos: A Personal Voyage”, which has been seen by more than 600 million people in over 60 countries, making it the most widely watched PBS program in history. A book to accompany the program was also published. He also wrote the novel “Contact”, the basis for the 1997 Robert Zemecki’s film of the same name starring Jodie Foster. During his lifetime, Sagan published more than 600 scientific papers and popular articles and was author, co-author, or editor of more than 20 books. In his works, he frequently advocated sceptical inquiry, secular humanism, and the scientific method. • www.carlsagan.com ‘Our Place in the Cosmos’ (ft.

Hubble’s Universe Unfiltered (1): Interacting Galaxies – Cosmic Collisions Galore. Hubble celebrated its 18th anniversary by releasing a huge image gallery of interacting galaxies. Such galaxies pass close enough to each other that their mutual gravity can stretch and distort their shapes. Eventually, interacting galaxies merge together to form a single larger galaxy. However, since these interactions can take billions of years, how do we study them? And how do we make sense of the variety of strange shapes seen in these Hubble images? — Subscribe to Science & Reason: • www.YouTube.com • www.YouTube.com — Astronomy textbooks typically present galaxies as staid, solitary, and majestic island worlds of glittering stars. But galaxies have a dynamical side. They have close encounters that sometimes end in grand mergers and overflowing sites of new star birth as the colliding galaxies morph into wondrous new shapes. In celebration of the Hubble Space Telescope’s 18th launch anniversary, 59 views of colliding galaxies constitute the largest collection of Hubble images ever released to the public. This new Hubble atlas dramatically illustrates how galaxy collisions produce a remarkable variety of intricate structures in never-before-seen detail. Notes: • Hubble was launched into orbit on April 24, 1990, aboard the space shuttle Discovery. However, there is a lot more to its history than just 18 years (so far) of cutting edge science. Take a look at Hubble Essentials for more …

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 ?
