- What James Cameron saw 6.8 miles deep in Mariana Trench
- How do we know that Challenger Deep is lowest point on Earth?
Using a custom-built submersible, filmmaker James Cameron has successfully visited the Challenger Deep, the deepest point in the world's oceans? How do we know that there isn't somewhere deeper?
- James Cameron describes deepest spot in ocean as 'barren'
Filmmaker James Cameron became the first person to make a solo dive to Challenger Deep, the deepest known point in the ocean, in a custom-built submersible.
- James Cameron dive launches race to the bottom of the world
Before James Cameron made a solo dive to the Challenger Deep – the deepest point in the ocean – only one mission had been there before. Now, several groups are planning deep-sea dives, and engineering advances could shed new light on the region.
- Past decade's extreme weather is manmade, new study suggests
Extreme rainfall and heatwaves over the past decade have been linked to global warming in a new Nature Climate Change study. The relationship between storms and warming is less clear.
- Bright Venus to show in daytime sky
Effulgent Venus will show just beside the moon today. Also, some cues on how to observe this rare and beautiful event.
- Angry Birds Space: Should you download it?
Review: Released on Thursday, Angry Birds Space offers dazzling new physics.
- Why James Cameron was forced to surface early
James Cameron described the Mariana Trench as "very lunar, a very desolate place, very isolated.” His six hour trip was cut in half by hydraulic problems.
- James Cameron makes final preparations for historic deep-sea dive
Weather permitting Saturday, explorer and filmmaker James Cameron could take his Deepsea Challenger to the bottom of the world, a place of perpetual cold, darkness, and abiding mystery.
- Angry Birds Space billed as an educational tool. Really?
Launched Thursday, Angry Birds Space, the latest installment to the wildly popular Angry Birds video game franchise, is being billed as a tool for educating people about physics. How scientifically accurate is the physics in the game?
- Runaway planets ejected from galaxy at insane speeds
New evidence suggests that planets are being tossed out of the Milky Way at speeds comparable to the speed of light.
- Massive, rocket-powered, robotic craft begins delivery mission to space station
The 13-ton cargo freighter is loaded with about 7.2 tons of supplies, including food, water, clothing, experiments and fuel for the space station, according to NASA.
- Titanoboa: How did a snake ever get so big?
Titanoboa: The new Smithsonian exhibit in Grand Central Station displays a replica of the largest snake in history, the 48-foot titanoboa. Why don't huge snakes exist today?
- Planets hurtling near the speed of light? It's possible, study says.
Scientists want to know if planets can form near the supermassive black hole at the core of the galaxy. If so, the black hole could fling them out into space at enormous speeds that, from our vantage point, could appear to approach the speed of light.
- 'Bird Man' admits video is a hoax
'Bird Man' Jarno Smeets became an Internet sensation when he posted a video of himself apparently taking flight with a pair of flapping wings. He subsequently admitted that the video was fake.
- Photos of asteroid Vesta reveal bright, ancient rock and dark, melted stone
The new photos of Vesta from NASA's Dawn spacecraft highlight odd, shiny spots that are nearly twice as bright as other parts of the asteroid — suggesting it is original material left over from the space rock's birth 4 billion years ago, NASA officials said today.
- Mercury: Unusual insides and active history
New information collected by NASA's Messenger shows that Mercury was more geologically active than scientists previously thought.
- NASA scientist's espionage attempt results in 13-year prison sentence
On Wednesday, Stewart Nozette, a high-profile former government scientist, was sentenced to 13 years for espionage after passing secrets to an FBI agent posing as an Israeli spy. He was also fined for tax evasion.
- Giant stars may not be necessary for supernovae
New research using X-ray and ultraviolet data helps scientists to better understand the origins of supernovae. These exploding stars are important in measuring distance in the universe.
- Strange features on Mercury upend thinking about 'first rock from sun'
New results from NASA's MESSENGER spacecraft show Mercury to have features unlike anything scientists have seen elsewhere in the solar system. Here's one: a huge core for a planet this size.
