The video is a bit long, but some cool stuff.

Whoa! Thank you for sharing!

Thanks Jim!

I enjoyed the video very much.

Fast and Light to Pluto

BY Dennis Overbye, Jason Drakeford and Jonathan Corum | Jul. 6, 2015 | 13:21

On July 14, 2015, the New Horizons spacecraft will zip past Pluto and its five known moons. Nobody really knows what it will find.

13+ minute video.

( Quote from the BBC: http://www.bbc.com/news/science-environment-33459476 )

... When it arrives at the dwarf planet, New Horizons will be travelling* at almost 14km/s -

far too fast to go into orbit.                       (*sic. U.K. spelling)

... New Horizons' difficulty is getting all that information back to Earth.

The distance to Pluto is vast - more than 4.5 billion km - and this makes for very low bit rates.

It will take 16 months to send back all the science acquired over the coming days.

I hope they're not transmitting all that info on 2.4gHz. =)

love it so much,thanks for sharing this !

Very nice, new mexico.  When I was in 8th grade I made a scale model of the solar system by taking hundreds of sheets of paper and taping them together into a big toilet paper roll of planets and space, where the sun was basically just a vertical line.  But driving through the desert to make that video looks like a lot more fun.

i love this animation of the curiosity rover landing; note that this is accomplished all by autopilot and programming; there is no way to do this remotely in real time, because the distance from earth to mars is too far for radio relay to work in the 14 minute transmission window.

Gravitational waves -- ripples in the fabric of spacetime -- aren’t just an Einstein theory any more.

A team of international scientists announced Thursday that they confirmed the waves’ existence -

after recording feedback from a black hole collision a billion light-years from Earth.

Hari Sreenivasan learns more from Dave Reitze of the California Institute of Technology.

I found this to be a fascinating read ... (From the 'New Yorker Magazine,' online.)

"Is what we have just realized yesterday about the gravitational waves similar to, for example, discovering the structure of DNA? Is it that big?" Theoretical physicist Brian Greene, astrophysicist Janna Levin, New York Times reporter Dennis Overbye, and Walter Isaacson, author of "Einstein: His Life and Universe," explain the significance of the discovery of gravitational waves.

February saw one of the most important astronomical breakthroughs of the decade, as a team of scientists “heard” gravitational waves -- a key postulate of Einstein’s theory of relativity -- for the first time in human history. Now, astrophysicist Janna Levin recounts that incredible discovery, and the human drama behind it, in her new book “Black Hole Blues.” Levin joins Jeffrey Brown for more.
