Explore our solar system beyond Earth to discover places that have liquid water, and therefore planetary predictors of extraterrestrial life, including Mars and some of the moons of Jupiter and Saturn, including Europa, Callisto, Ganymede and Enceladus. ...
In 1943 he reported that "it seems safe to conclude from the Lowell surveys that no unknown planet beyond Saturn exists that [is] brighter than magnitude 16½ at the time of search."The name 'Pluto' was proposed soon after its discovery by 11-year-old British schoolgirl Venetia Burney, ...

Occasionally, the pull of gravity stretches portions of the debris into filaments, and this year, there's a chance Earth will pass through a filament of debris that is almost 450 years old. Editor's note: If you snap an amazing photo of the Leonid meteor shower of November 2014, or any...
There's a weird, disappearing dark spot on Saturn's moon EnceladusEnceladus' ice plumes might be the reason why a dark spot on the moon is disappearing. But what is the spot in the first place?Space Shaanxi Sheng: AI guru Andrew Ng recommends: Read These 5 Books And Turn Your Life Aro...
With the new findings suggesting that phosphorus could be relatively plentiful, Glein argues that we need to visit the place again to learn more: “We need to get back to Enceladus to see if a habitable ocean is actually inhabited.”
For space physicist Xianzhe Jia, PhD, of the University of Michigan, the allure of the moon is simple: “It looks colorful.” 3. Enceladus NASA NASA Saturn’s tiny 310-mile-wide moon, Enceladus, didn’t look like much at first. “We thought it would be frozen solid,” says Spilker....
The 3K system has many uses. It brings a consistent set of principles, facilitates comparison at different scales, and perhaps can even hint at predictions — e.g., should there be a class of planetary jets (think Enceladus) analogous to stellar jets (S 20) and galactic jets (G 11)?
What is the evidence that Enceladus, a moon of Saturn, has liquid water underneath its icy surface?Calculate the age of a rock using the following information: the half-life of a radio-isotope, and the ratio of parent to daughter isotope. Use examples....
We might find life on Mars, or Enceladus, or Europa, he notes, and it might look like an organism that died out during a mass extinction down here. “But I might have that completely wrong,” he adds. “Some of the strange examples they came up with on Star Trek might be a better...
