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.

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 ...

"Of all the sciences cultivated by mankind, Astronomy is acknowledged to be, and undoubtedly is, the most sublime, the most interesting, and the most useful. For, by knowledge derived from this science, not only the bulk of the Earth is discovered ...; but our very faculties are enlarged with the grandeur of the ideas it conveys, our minds exalted above [their] low contracted prejudices." --James Ferguson, "Astronomy Explained Upon Sir Isaac Newtons Principles, And Made Easy To Those Who Have Not Studied Mathematics" (1757) --- Subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com --- The Cosmic Perspective Long before anyone knew that the universe had a beginning, before we knew that the nearest large galaxy lies two and a half million light-years from Earth, before we knew how stars work or whether atoms exist, James Ferguson's enthusiastic introduction to his favorite science rang true. Yet his words, apart from their eighteenth-century flourish, could have been written yesterday. But who gets to think that way? Who gets to celebrate this cosmic view of life? Not the migrant farmworker. Not the sweatshop worker. Certainly not the homeless person rummaging through the trash for food. You need the luxury of time not spent on mere survival. You need to live in a nation whose government values the search to understand humanity's place in the universe. You need a society in which intellectual pursuit can take you to the frontiers of discovery ...

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.

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 ...

Hubblecast 25: What's Next? Amazing Telescopes Of The Future. The telescope has been mankind's window on the Universe for four hundred years. It has provided scientists with unprecedented views of planets, stars and galaxies from our cosmic doorstep to the very depths of space and time. But despite their incredible performance, even the newest and most powerful telescopes leave room for improvement. Astronomers always want to venture beyond their current horizons. In this final chapter we take a look at things to come - the revolutionary ground-based telescopes and space observatories of the future.
