At a press conference today (April 22) at the Museum of Flight, three prominent astronauts supporting the B612 Foundation presented a visualization of new data showing evidence for 26 atom-bomb-scale asteroid impacts since 2000. The evidence comes from recently released data from the Nuclear Test Ban Treaty Organization, which operates a network of sensors that monitors Earth around the clock listening for the infrasound signature of nuclear detonations.
Researchers investigating “night-shining” clouds found something they weren’t even looking for: teleconnections in Earth’s atmosphere that stretch all the way from the North Pole to the South Pole and back again
If you could see stars and planets from outer space, both would shine steadily. But – from Earth – stars twinkle while planets shine steadily. Why?
Here’s a unique perspective, from cameras mounted on the upper stage of the Soyuz rocket that sent Europe’s Sentinel-1A satellite into space last week.

Earth and Mars are converging for a beautiful close encounter in April, an event astronomers call “the opposition of Mars.”
If you live at a high latitude, be alert for a good display of auroras, or northern lights, beginning late tonight (April 1, 2014) and into tomorrow night. NOAA forecasters estimate a 60% chance of polar geomagnetic storms on April 2. Video shows the X-flare that took place on Saturday, March 29. One of the incoming CMEs is from this flare.
A BBC production shows a crow solving an 8-step puzzle to get food.
A few years ago, the BBC hired Brad Josephs to guide a film crew for a production called the Great Bear Stakeout. His main assignment was to track a monster male bear they called Van, tracking wolves and hoping to film them with bears, and most importantly, to help set up remote, unmaned cameras to get super up-close wide angle shots that would be impossible to film otherwise. This great video is one result of that experience.
It’s just cool, that’s all. Watch this 40-second video of an octopus squeezing through a tiny hole to escape a box.
