JPL Announces Discovery of Largest Saturnian Ring

Today, NASA's Jet Propulsion Laboratory announced the discovery of the largest known ring system around Saturn, the second largest planet in our Solar System, and it's quite intriguing.

This new belt lies extremely far from the gas giant, beginning around 3.7 million miles (6 million kilometers) away from the planet and continues outward for roughly another 7.4 million miles (12 million kilometers). This ring is extremely thick as well, being 20 times the diameter of the planet. Phoebe, one of Saturn's farthest orbiting moons, circles within this newly found ring, and is likely the source of the rings material.

The information I have presented here is only a very little bit of the data collected from this new discovery. For more information please see the official press release.

LCROSS: First Steps to Colonizing Space

Ever since man has discovered its place within the Universe we've been energized by the thoughts of colonizing other bodies other than the Earth. When we landed on the Moon we were at the pinnacle of our goal which was to place a man on the Moon. After which we followed a non-existent approach to space exploration by simply only having interests in launching satellites for quite some time.

It's about time we start seriously thinking about colonizing space, yes? Enter, LCROSS: Lunar CRater Observation and Sensing Satellite.

In April 2006, NASA selected the LCROSS proposal for a low-cost, fast-track companion mission to the Lunar Reconnaissance Orbiter (LRO). The main LCROSS mission objective is to confirm the presence or absence of water ice in a permanently shadowed crater near the lunar south pole.

LCROSS launched with the Lunar Reconnaissance Orbiter aboard an Atlas V rocket from Cape Canaveral, Fla., on June 18, 2009. After launch, the LCROSS shepherding spacecraft and the Atlas V's Centaur upper stage rocket executed a fly-by of the moon on June 23 and entered an elongated Earth orbit to position LCROSS on a correct trajectory to impact the lunar south pole on October 9, 2009. On final approach, the shepherding spacecraft and Centaur will separate. Both spacecrafts will then impact and do their jobs.

Finding water ice on the moon will be crucial for the beginnings of colonizing...don't think I really needed to explain that but yea.

I'll be posting news data about this mission and others so stay tuned.

Hubble Space Telescope Better Than Ever!

Since its placement in near-Earth orbit on the 24th of April, 1990 the Hubble Space Telescope has been taking amazing images of interstellar space like none have before. Recently the telescope has undergone an upgrade, or more known throughout the NASA community as a "surgery" of sorts and is back in action.

Pictured above is the gravitational lensing effect observed of Galaxy Cluster Abell 370, probably one of the most interesting effects observed in the observable Universe so far.

"Galaxy clusters are the most massive structures of the universe, located at the crossing of the filaments of the cosmic web of dark matter. The most massive clusters can contain up to 1,000 galaxies and intergalactic hot gas, all held together primarily by the gravity of dark matter."

These observations were made with Hubble's Advanced Camera for Surveys (ACS) in its Wide Field mode on July 16, 2009. The composite image was made using filters that isolate light from green, red, and infrared wavelengths.

Be expecting the Hubble Space Telescope to ensure many more astronomic breakthroughs in the near future. Oh, and by all means don't forget to browse through The Hubble Space Telescope's NASA Homepage.
