6 years of sun observation in HD

Solar Dynamics Observatory (SDO) keeps a 24-hour eye on the entire disk of the sun, with a prime view of the graceful dance of solar material coursing through the sun’s atmosphere, the corona. The video shows six years – from Jan. 1, 2015, to Jan. 28, 2016, as one time-lapse sequence. Watch the magnetic fields in HD and get the explanations in the second part of the video – terrific work by the NASA Goddard Space Flight Center!

All roads lead to Rome! – interactive trajectory maps

3.375.746 journeys resulted in 500.000 routes from all across the continent…and there is an interactive map that is showing all of it. The people from movel.lab aligned starting points in a 26.503.452 km² grid covering all of Europe. Every cell of this grid contains the starting point to one of our journeys to Rome. They’ve done the same with other cities as well, very interesting and well done.

The Reusable Rocket is Finally Real

Vastly covered, nevertheless impressive engineering by the Blue Origin team that managed (in contrary to SpaceX) to bring back a rocket in one piece.
“The Shepard space vehicle reached thee edge of space at a suborbital altitude of 100.5 kilometers. The capsule then separated and touched down beneath a parachute but the BE-3 rocket also started its own descent. After the rockets fired at nearly 5,000 feet, it made a a controlled vertical landing at a gentle 4.4 mph.” Wicked!

The Super-K observatory

Forget CERN, the science fiction is here (compare with the movie Event Horizon): Super-Kamiokande, a neutrino observatory built 1993-1996 and located under Mount Kamioka in Japan. The observatory is designed to search for proton decay, study solar and atmospheric neutrinos, and keep watch for supernovae in the Milky Way Galaxy. The Super-K is located 1,000 m underground and consists of a cylindrical stainless steel tank that is 41.4 m tall and 39.3 m in diameter holding 50,000 tons of ultra-pure water.
