Gigantic X-Ray Tsunami Rolls Through Galaxy Cluster (Video, Photos)
A wave of hot gas twice as wide as the Milky Way galaxy roils the nearby Perseus galaxy cluster, a new study indicates. The wave, which measures 200,000 light-years across, likely formed billions of years ago, after a neighboring cluster clipped Perseus, researchers said. You can watch the monster wave roll in this awesome NASA video. "The wave we've identified is associated with the flyby of a smaller cluster, which shows that the merger activity that produced these giant structures..>> view originalIf we successfully land on Mars, could we live there?
Terraforming: It Won’t Be Quite Like the Movies at First When you think of astronauts on Mars, what comes to mind? Did you picture a red planet turning green with time and continued human colonization? Unfortunately, those days are far in the future, if they even happen at all. During the interview, Davis explained, “Terraforming has a connotation of humans making another planetary body, like Mars, Earth-like. But really, it’s about humans changing their environment to make it more supportive o..>> view original'Significant' New Rift Could Sever Massive Iceberg From Antarctica
Scientists have observed a new rift in Antarctica’s Larsen C ice shelf that could soon lead to the calving of one of the biggest icebergs on record. A secondary branch has split off from a 100-mile-long crack in the ice shelf that’s been growing since 2010, researchers with the United Kingdom-based Project MIDAS announced this month. Project MIDAS tracks the effects of climate change on the Larsen C. That new rift, which is about 6 miles long, has forked toward the ice-front, or the region wher..>> view originalThis classic sci-fi solar system looks a lot like home
Click the thumbnail for a comparison of our solar system and the Epsilon Eridani system. NASA/JPL/Caltech/R. Hurt (SSC) Good news for fans of "Babylon 5." Astronomers have revealed some exciting details about the sci-fi series' real-life setting, the Epsilon Eridani star system.It turns out the relatively nearby star system, setting of the oft-forgotten and overly complex '90s space opera, is rem..>> view originalSpaceX plans to launch first internet-providing satellites in 2019
SpaceX has its sights set on Mars, but that doesn't mean it has forgotten about Earth. Elon Musk's company yesterday outlined its plan to put a network of internet-providing satellites around our planet, stating in a Senate hearing on broadband ...>> view originalThar She Blows: Tips To See Whales In Action Off The California Coast
During the last 10 years, whale sightings in Southern California have been on the rise. “Southern California is one of the best places in the world to spot gray whales and is arguably where whale watching eco-tourism was born,” Diane Alps of the American Cetacean Society (ACS) and whalesafe.org said. For residents of Malibu, spotting whales is as easy as a stroll down the beach around Point Dume, a favorite spot among migrating gray whales, which can be seen right off shore in the surf. For a b..>> view originalMeasuring Walking Speed Using Wireless Signals May Help Predict Cardiac Diseases And Cognitive Decline
How fast a person walks can help predict health issues such as cognitive decline as well as cardiac and pulmonary diseases. Slow walking speed may also be attributed to heart, lung, and nervous system problems and joint pain. Research has shown that people whose walking speed is slower than 0.6 meters per second (2 feet per second) may have increased odds for poor health and function. Accurately monitoring a person's walking speed though poses challenges in that it has to be continuous and unob..>> view originalStephen Hawking Thinks Humans Have Only 100 Years to Leave the Earth
Stephen Hawking thinks that humanity must leave Earth in the next century, and colonise another planet to ensure their survival, considering the dangers that lie ahead of us.The renowned English theoretical physicist made the claims as part of a new documentary – Expedition New Earth – that’s set to air on BBC Two over the summer. As part of his predictions, Hawking said the effects of climate change, overdue asteroid strikes, epidemics, and population growth has put the planet in an “increasing..>> view originalDetailed look at the global warming 'hiatus' again confirms that humans are changing the climate
For years, the global warming ‘hiatus’ from 1998 to 2012 puzzled scientists and fueled skeptics looking to cast doubt on the very idea that Earth’s temperature has been on the rise, largely because of human-produced greenhouse gas emissions such as carbon dioxide — and that significant policy changes would need to be made to keep that rise in check.Recent papers have begun to chip away at the idea of the slowdown. Now, a new analysis in the journal Nature brings together many of those arguments..>> view originalNasa's Cassini spacecraft shows incredible view of Saturn
Nasa has released a stunning video taken by the Cassini spacecraft showing the view during its first dive into Saturn's rings last month.It begins with a view of the swirling vortex at the planet's north pole, then heads past the outer boundary of the hexagon-shaped jet stream and beyond.The movie comprises one hour of observations as the spacecraft moved southward over Saturn on April 26.
