Ok... nu är det jäkligt mycket geek-varning på mig här men... jag hittade dessa bilder som Nasa har tagit! Jag var bara tvungen att lägga upp några här med tillhörande text. Bild nummer 1 visar en bild av vår galax - Milky Way. Under bilden står det att forskare tror att det finns ca 50 miljader planeter i vår galax och att 500 miljoner av dem befinner sig i en "inte för varmt, och inte för kallt" -zon och att det mycket väl skulle kunna finnas liv på dessa planeter. 500 miljoner bara i vår galax liksom!? Ogreppbart! Och för att inte tala om bild nummer 2... det ser ju ut som en sån där kackig 80-tals fantasyplansch, men det är liksom på riktigt!!? Typ dör på sånt här! *hello geek*
This 1986 picture shows part of the Milky Way galaxy as seen from Australia. Scientists have estimated there are at least 50 billion planets in our galaxy, of which at least 500 million are in the not-too-hot, not-too-cold zone where life could exist.
The Hubble telescope was responsible for this stunning image. It shows a three-light-year-tall pillar of gas and dust that is being eaten away by the brilliant light from nearby bright stars. The pillar is also being assaulted from within, as infant stars buried inside it fire off jets of gas that can be seen streaming from towering peaks. This turbulent cosmic pinnacle lies within a tempestuous stellar nursery called the Carina Nebula, located 7,500 light-years away in the southern constellation Carina.
Several hundred never before seen galaxies are visible in this "deepest-ever" view of the universe, called the Hubble Deep Field (HDF), made with the Hubble telescope in 1996. Besides the classical spiral and elliptical shaped galaxies, there are a variety of other galaxy shapes and colours that are important clues to understanding the evolution of the universe. Some of the galaxies may have formed less that one billion years after the "big bang." Representing a narrow "keyhole" view all the way to the visible horizon of the universe, the HDF image covers a speck of sky 1/30th the diameter of the full moon.
Over the last 50 years Nasa has developed a number of space explorer craft, to give more views of deep space. This image is from Nasa's Wide-field Infrared Survey Explorer (Wise); the instrument spots celestial objects that give off infrared light. Andromeda is the closest large galaxy to our Milky Way galaxy, and is located 2.5 million light-years from our sun.
Arguably one of Nasa's biggest success stories has been the Hubble Space Telescope, which has given scientists a whole new look at space and the origins of the universe. Hubble has captured images of various galaxies, including this celestial object that looks like a delicate butterfly.
This high-quality image from Hubble is so incredibly sharp it could be enlarged to billboard size and still retain all of its stunning details. This Whirlpool Galaxy image showcases the spiral galaxy's classic features, from its curving arms, where new-born stars reside, to its yellowish central core that serves as home for older stars. The graceful, winding arms of this galaxy are actually long lanes of stars and gas laced with dust. There is also a small galaxy, known as NGC 5195, which is passing behind the Whirlpool.
