Watch a whale check out an ROV 600m/2000' down in the Gulf of Mexico

NautilusLive is a project of deep-sea explorer Robert Ballard and others. They've been exploring methane seeps in the Gulf of Mexico, when this very unexpected encounter happened (go full screen if you can):


The spontaneous comments from the surprised techs and scientists are great.

Meteorite chunks create "snow carrots" in Russia

Only 0.02% of last year's huge Chelyabinsk Meteor was ever recovered --- most of it vaporized or scattered into unrecoverable particles --- but scientists are still learning from it.

For example:

When hot meteorite fragments hit snow, they melt a vertical shaft or tunnel to the ground. The melted walls of the shaft re-freeze, and the resulting ice wall is denser than the surrounding snow. When the lighter snow melts, the harder-to-melt ice shaft is temporarily left behind as a hollow, standing cylinder.

"The February meteor blast over central Russia glowed 30 times brighter than the sun, sunburned observers, and delivered the biggest astronomical punch felt on Earth in a century, report scientists.

"'Not just the windows were broken, but the window frames were pushed in, in the buildings,' said Jenniskens in a Science podcast. 'The [shockwave] was so strong that it was able to topple over people standing.'
