Picture of the moon

In this photograph can be seen lunar craters on the moon, and seas of the moon, the darker and flat areas of the Moon. The seas of the moon can be seen with the naked eye, especially when the moon is full and that has the name of seas such as the famous "sea of tanquilo" in which the astronaut Neil A. Armstrong landed on the moon in 1969, never have hosted water inside, are actually lava fields that...

Hubble Images of Asteroids Vesta and Ceres

These Hubble Space Telescope images of Vesta and Ceres show two of the most massive asteroids in the asteroid belt, a region between Mars and Jupiter. The images are helping astronomers plan for the Dawn spacecraft’s tour of these hefty asteroids.On July 7, NASA is scheduled to launch the spacecraft on a four-year journey to the asteroid belt. Once there, Dawn will do some asteroid-hopping, going...

Weather Without Water

Bright mid-latitude clouds near the bottom of this view hint at the ongoing cycling of methane on Titan. These cloud streaks are near the same latitude as similar clouds observed above different longitudes on Titan.The view is centered on Titan's trailing hemisphere, over the 1,700 kilometer (1,050 mile) wide bright region known as Adiri. North on Titan (5,150 kilometers, or 3,200 miles across) is...

Messenger Flies By Venus

The MESSENGER spacecraft snapped a series of images as it approached Venus on June 5. The planet is enshrouded by a global layer of clouds that obscures its surface to the MESSENGER Dual Imaging System (MDIS) cameras.This single frame is part of a color sequence taken to help the MESSENGER team calibrate the camera in preparation for the spacecraft’s first flyby of Mercury on January 14, 2008. Over...

ESA takes steps toward quantum communications

A team of European scientists has proved within an ESA study that the weird quantum effect called 'entanglement' remains intact over a distance of 144 kilometres. The experiment allows ESA to take a step closer to exploiting entanglement as a way of communicating with satellites with total security.Quantum entanglement is one of the many non-intuitive features of quantum mechanics. If two photons...
