Movie maker plans trip the bottom of the Sea

Movie maker plans trip the bottom of the Sea
The Mariana Trench is so deep (seven miles) that it could swallow Mt. Everest. (5miles high) It so dangerous that it has only been visited once by the US Navy by two men onboard the bathyscaphe Trieste on 23 January 1960 and then they could only stay for 20 minutes. In fact six time as many men (12) have walked on the Moon than have been to the bottom of the Mariana.  Now James Cameron; director of the Avatar and Titanic; plans on making the seven miles trip

Saturn's Moon Dione has Oxygen

Saturn's Moon Dione has Oxygen
Dione is a 700 miles diameter moon discovered astronomer Giovanni Cassini in 1684. It obits Saturn at about a quarter of a million miles every 2.7 days, This small moon is seems to be mainly thick water ice around an
even smaller smaller rocky core. Recently the Cassini spacecraft (named for the discoverer of Dione) found molecular oxygen ions (O2+) during a 2010 pass of Dione. The oxygen ions are a result of charged particles from Saturn's magnetosphere that strip an electron from the oygen molecules. The same magnetosphere then strips away these oxygen ions fron the Moons atmosphere.

Venus is Slowing Down

The ESA’s Venus Express has shown that the rotation rate of Venus is Slowing Down and at an amazingly fast rate. Venus is already an odd planet in that it rotates in the opposite direction that the sun and other planets do. However the length of its day had increased 6.5 minutes in just 16 years. While that may not look like much, it is blazingly fast by planetary terms where the Earths rotational period increase increased by only a few seconds in the same time

This poses a problem for 4.5 billion years usualy given as the age of the Solar System becuses projecting back the rotation rate gets imposibly fast way befor the billion year mark.

Newton's 2nd Law of Motion


Newton's 2nd Law of Motion states that a mass acted on by a force undergoes acceleration in the direction of the force, with a magnitude inversely proportional to the mass and proportional to the force.

Nearby Dwarf Galaxy Challenges Galaxy Formation Models

Nearby Dwarf Galaxy Challenges Galaxy Formation Models

A recent discovery of bright nebular gas emissions around a near by dwarf galaxy Iraises problems for galaxy formation models. This dwarf galaxy is close enough to distinguish nebular gas emissions from star light. The
emissions result from heavy supernova activity.
