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 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 ?

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.

Hubblecast 01: ‘Comet Galaxy’ Being Ripped Apart By Galaxy Cluster. The NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy cluster’s gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular- or elliptical-shaped galaxies over billions of years. — Subscribe to Science & Reason: • www.YouTube.com • www.YouTube.com • www.YouTube.com — Credit: • ESA/Hubble (M.
