The existence of oceans or lakes of liquid methane on Saturn's moon Titan was predicted more than 20 years ago. But with a dense haze preventing a closer look it has not been possible to confirm their presence. Until the Cassini flyby of July 22, 2006, that is. Radar imaging data from the flyby, published this week in the journal Nature, provide convincing evidence for large bodies of liquid. This image, used on the journal's cover, gives a taste of what Cassini saw. Intensity in this colorized image is proportional to how much radar brightness is returned, or more specifically, the logarithm of the radar backscatter cross-section.
Saturn’s moon Enceladus is a strange place. The cold, tiny moon in the far reaches of the solar system is an unlikely location for liquid water. Yet scientists have not only discovered that Enceladus contains water, it actually shoots magnificent plumes of it out into space. These plumes and their origin remain a major mystery for researchers studying the moon and its environment. Where is the source of their liquid water and what causes them to fire out into space? Here, Wired takes a closer look at the plumes in some of our favorite images of our favorite Saturnian moon.
The view of Earth from space has transformed our understanding of, as well as our admiration for, the planet. The data and images collected by Earth-observing satellites have been used in thousands of scientific papers, helped us better respond to natural disasters, improved weather and climate forecasts, enlightened us about our impact on Earth and captivated us with beauty. One of the stars of NASA's fleet of satellites is Aqua. The satellite is named for its ability to measure water vapor in the atmosphere, water in the oceans, as well as ice and snow. When it was launched on May 4, 2002 , scientists expected it to work for three to five years.
The lion is one of the four big cats, and is also known as the king of all animals. Wild lions currently exist in Africa and Asia. They typically inhabit savanna and grassland, sometimes they may be found in the bush and the forest.
