People: Featured People: Carl Sagan Carl Sagan played a leading role in the American space program from its very beginning. He was a consultant and adviser to NASA beginning in the 1950s -- he briefed the Apollo astronauts before their flights to the Moon. Carl was born in New York City on November 9, 1934. He described himself as a childhood science fiction addict who became fascinated by astronomy when he learned that every star in the night sky was a distant sun. He was always encouraged by his parents to research answers to his innumerable questions about science. His scientific curiosity led him to earn four degrees in physics, astronomy and astrophysics from the University of Chicago.

Amazing Hubble Pictures Photograph courtesy John Spencer (Lowell Observatory) and NASA In 1999, to commemorate the ninth anniversary since its launch, the Hubble Space Telescope took this dramatic snapshot of Jupiter’s moon Io and its shadow sweeping across the gas giant’s turbulent atmosphere. About the size of Earth’s moon, Io is the most volcanic body in the solar system and orbits 500,000 kilometers above the planet’s cloud tops. l'univers et ses mystères au COMPLET en haute definition Les plus grandes explosions HD 720p / Nouveau documentaire science complet en francais by DocMeFiLDraGoN3 47,053 views Documentaire science issu de : l'univers et ses mystères ceci est l'episode 47Science documentary : the universe and its mysteries this is episode 47
Astronomie - MESSENGER arrive aux abords de Mercure - AstroSurf Envoyé 03-01-2008 19:42 j'ai relevé ces precisions sur le site, où il s'avère que c'est bien pour diminuer la vitesse de la sonde afin qu'elle soit capturée par Mercure...Mais ça ne répond pas tout à fait à la question : pourquoi peut-on envoyer directement une sonde en orbite de Mars et pas de Mercure ? Rôle joué par le Soleil, faible masse de Mercure ?? "5. Why take such a long and complex route to Mercury? Although it is not that difficult to fly a spacecraft by Mercury, the task of placing a spacecraft into orbit around the planet is a significant challenge.
SINGS Hubble tuning fork poster This poster displays the 75 SINGS galaxies arranged in a tuning fork based on their optical morphology. The color images of each galaxy were created from the SINGS IRAC 3.6um (blue), IRAC 8.0um (green), and MIPS 24um (red) images. This poster represents summarizes a large amount of work carried about by the SINGS team in writing the original proposal, planning the observations, reducing the data, and many studies devoted to understanding what the images mean. Most of the work for the poster itself was carried about by Karl Gordon with significant help from Robert Hurt. Many SINGS team members and Spitzer Science Center staff contributed helpful comments and advice. The Spitzer Science Center has a feature article on this poster.
Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2016 April 15 Mercury and Crescent Moon Set Image Credit & Copyright: Miguel Claro (TWAN, Dark Sky Alqueva) Explanation: Innermost planet Mercury and a thin crescent Moon are never found far from the Sun in planet Earth's skies. Taken near dusk on April 8, this colorful evening skyscape shows them both setting toward the western horizon just after the Sun.
The Very Curious Creation of an Ageing Star The NASA/ESA Hubble Space Telescope has made a rare celestial catch. Close to a bright, nearby star in this image, the bizarre, whorl-shaped object known as IRAS 22036+5306 has been captured during a brief tumultuous period late in a star's life. Inside IRAS 22036+5306 lies an aged star that has coughed off almost all of its outer material, forming a cloud in space. Hidden under this veil, the dense, still-burning, exposed core of the star grows hotter. Encircling the star is a torus consisting partly of castoff material, as well as possibly the grainy remnants of comets and other small, rocky bodies. Twin jets spout from the star’s poles and pierce this dusty waist.
