Mumuration / Swarm behaviour

I really like crowd behavior but birds are showing by far the most amazing formations of all creatures on earth. If you agree then type “mumuration” in your favourite search bar. Read a scientific investigation of this phenomena published in PNAS here or the short version here.

Check the BBC Wildlife Special about Swarming with plenty of more swarm recordings!

Aurora/Northern Lights

It is almost too cheesy to be true but Northern Lights/Aurora are in fact real and caused by charged particles, mainly electrons and protons, entering the atmosphere from above causing ionisation and excitation of atmospheric constituents, and consequent optical emissions. Click here for more information. Thanks to high-resolution recordings we can enjoy them from home.

New high-resolution galaxy shots

ESO, the European Southern Observatory has published new impressive pictures made by the VST-Tube-System showing star-forming region Messier 17, also known as the Omega Nebula or the Swan Nebula and the best portrait of the globular star cluster Omega Centauri ever made. Full resolution(!) and plenty of beautiful outer space pictures are available on the ESO page.

What a reentry into the atmosphere looks like

Fantastic footage, once again from NASA. A 10 minute video of “Orion’s flight test show the plunge through Earth’s atmosphere, when searing plasma so hot it appears purple (upper left) surrounds Orion.A few minutes later you can witness the jettison of the forward bay cover, followed by the release of the drogue chutes and then the main chutes (lower left). It’s all right there before your eyes just as it happened on Orion and how future astronauts will see it when they return from deep space missions and one day coming home from Mars.”

Corals and sponges in HD

Incredible recordings from Daniel Stoupin: “Slow marine animals show their secret life under high magnification. Corals and sponges are very mobile creatures, but their motion is only detectable at different time scales compared to ours and requires time lapses to be seen. These animals build coral reefs and play crucial roles in the biosphere, yet we know almost nothing about their daily lives.”
