Temple 1 Impact – 245 viewsOn July 4, 2005, NASA sent an 820 pound Impactor into a comet named Temple 1. The impact was successful, and its aftermath caused large amounts of comet materials to spew into space. The comet increased in brightness 62 times from the impact. This image was captured by the Hubble Telescope which was monitoring the mission.

Andromeda Galaxy – 366 viewsThis Hubble image shows our nearest galactic neighbor: the Andromeda Galaxy. Andromeda can actually be seen in the constellation with the same name with the naked eye. It appears as grayish smudge in the sky. This galaxy is on a collision course with our own, and some billions of years in the future the two will collide. It is thought that the stars of each galaxy will simply pass through each other due to the enormous space between them.

M80 Star Cluster – 254 viewsThere are over 200 star clusters found in our own Milkyway Galaxy. Star clusters are tight groupings of stars birthed together, therefore you could say they are stellar nursuries. M80 has hundreds of thousands of stars all compacted together. It is thought that all stars are born this way, and that over large eons of time drift to become field stars, like our own sun, a star light years away from any neighbor.

Galactic Center in Infared – 271 viewsBecause so much stellar dust obscures visual images through telescopes, NASA used an infared imaging device to take a picture of the center of our own galaxy. This technology reveals more than a plain visual image. And of course, what it reveals is a massive nucleus of matter.

Whirlpool Galaxy – 273 viewsThis Hubble image shows the Whirlpool galaxy with its large swirling arms. The smaller yellow glob at the edge of the upper arm is another galaxy.

First Exoplanet Visual: 2M1207b Orbits a Brown Dwarf – 254 viewsThe red dot is the first planet visually seen outside our solar system. The object displayed a spectrum of light revealing water vapor and therefore cooler temperatures. It has been following the brown dwarf star since discovered indicating that it is orbiting the star. The planet is thought to be five times the size of Jupiter, its orbit around the star approximately 1500 earth-years long, and is about 170 light years away from our solar system. This star and planet lie in Hydra.

Hubble Deep Field – 262 viewsNASA peered into a dark point of space in Ursa Major taking pictures over a period of ten days with the Hubble Telescope. First swirls and globs appeared, each a galaxy. But as additional frames were layered NASA began to see a mind-numbing well of infinitude appear before them. Each dot and blink is itself a galaxy, extending beyond what our technology can see. Each unknown galaxy contains countless stars.

M7 Open Star Cluster in Scorpius – 253 viewsThis picture is a look towards the center of our own galaxy. The blue stars belong to a star cluster approximately 1000 light years away from Earth, but as NASA took pictures the innumerable stars of the galactic center blinked into view. No one knows how many stars the Milky Way Galaxy has. Modest estimates number them at 100 billion, with many scientists doubling this number!
