NASA - fotografije

NASA (The National Aeronautics and Space Administration) je agencija Americke vlade, odgovorna za svemirski program kao i civilno i vojno istrazivanje kosmosa (izvor). Osnovana je 29. jula 1958. Razlog zasto ovo pisem je Nevena. Trazila mi je prosle godine fotografije (istina, drugacijeg sadrzaja), da bi ih odstampala i napravila slike. Inace ideja je odlicna. Ja sam tada pretrazio fotografije koje sam imao. Nasao sam ono sto je njoj trebalo, ali je rezolucija tih slika bila nedovoljna da bi posle stampanja to stvarno bilo lepo. Kasnije sam naisao na sajt NASA-e i otkrio da imaju veliku galeriju i odlicne fotografije. Mozete da ih download-ujete u razlicitim rezolucijama (cak i u 'originalnoj' velicini).
Evo par zanimljivih fotografija:




Atlantis

A flock of birds took flight shortly after the Space Shuttle Atlantis arrives at Pad 39B after being rolled out from the Vehicle Assembly Building for its third voyage in 1988. Atlantis launched in late November 1988 on mission STS-27, a Department of Defense dedicated mission.











Discovery Lifts Off!

Space shuttle Discovery leaps from its launch pad on Tuesday, Oct. 23, 2007, to begin the STS-120 mission to the International Space Station.







The View From Iapetus

While on final approach for its September 2007 close encounter with Saturn's moon Iapetus, Cassini spun around to take in a sweeping view of the Saturn System.Iapetus (1,468 kilometers, or 912 miles across) is the only major moon of Saturn with a significant inclination to its orbit. From the other major satellites, the rings would appear nearly edge-on, but from Iapetus, the rings usually appear at a tilt, as seen here.In the high resolution image, the following moons are visible: Dione (1,126 kilometers, or 700 miles across) at center left, Enceladus (505 kilometers, or 314 miles across) near the left side ansa (or ring edge), Mimas (397 kilometers, or 247 miles across) a speck against the ring shadows on Saturn's western limb, Rhea (1,528 kilometers, or 949 miles across) against the bluish backdrop of the northern hemisphere, Tethys (1,071 kilometers, or 665 miles across) near the right ansa, and Titan (5,150 kilometers, or 3,200 miles across) near lower right.










Evaporating Planet

Planet HD 209458b is evaporating. It is so close to its parent star that its heated atmosphere is simply expanding away into space. Some astronomers studying this distant planetary system now believe they have detected water vapor among the gases being liberated.This controversial claim, if true, would mark the first instance of planetary water beyond our solar system, and indicate anew that life might be sustainable elsewhere in the universe. Although spectroscopic observations from the Hubble Space Telescope are the basis for the water detection claim, the planetary system is too small and faint to image. The image is an artist's concept of the HD 209458b system.









Snowflakes in the Universal Sky

Like cascading snowflakes in the interstellar night, the strange shapes and textures of the stars in the Snowflake Cluster abound in the Cone Nebula. These patterns result from the tumultuous unrest that accompanies the formation of the open cluster of stars known as NGC 2264. Bright stars from the cluster dot the field and they soon heat up and destroy the gas and dust mountains in which they formed. One such dust mountain isheat up and destroy the gas and dust mountains in which they formed. One such dust mountain is the famous Cone Nebula, visible in the above image on the left, pointing toward a bright star near the center of the field.
