Every year, sea ice fluctuates through the seasons, growing in the winter and shrinking in the summer. This year, Arctic sea ice reached its annual maximum on March 13, 2019. It wasn’t a record low, but it continued a trend of declining sea ice maximums and minimums. […]
The ESO has three astronomical observation sites spread across the Atacama region in Chile: Paranal with its VLT telescopes and soon the E-ELT, the oldest site: La Silla and ALMA located above 5000m/16400ft. Shot during the ESO UltraHD expeditions in 2011 and 2014, Christoph Malin spend many nights under the stars shooting the nightsky with advanced capturing and exposure ramping techniques. Together with state of the art post-production techniques we were able to remaster the old RAW-sequences in crisp 4K for 2019s viewing standards. Shot on Nikon D3s (2011) and Canon 6D (2014) cameras with GBT ramping software. […]
Only at the Pole – the sun circles around the horizon in 24h here is a time-lapse of nearly 5 days from March 08-13, 2017. So only a few days until sunset so in the course of 360° the sun moves a bit closer to the horizon.
Since the very first module Zarya launched from Baikonur Cosmodrome on 20 November 1998, the International Space Station has delivered a whole new perspective on this planet we call home. Join us as we celebrate 20 years of international collaboration and research for the benefit of Earth with ESA astronaut Alexander Gerst’s longest timelapse yet.
In just under 15 minutes, this clip takes you from Tunisia across Beijing and through Australia in two trips around the world. You can follow the Station’s location using the map at the top right-hand-side of the screen alongside annotations on the photos themselves.
This timelapse comprises approximately 21 375 images of Earth all captured by Alexander from the International Space Station and shown 12.5 times faster than actual speed. […]
I’d been hearing a lot about Betelgeuse lately, and I hadn’t realised how immensely huge it is. So I decided to make this short video which shows the size of Betelgeuse as compared to our Sun and the Solar System. I know VY Canis Majoris is bigger (actually even larger stars have been discovered), but this video isn’t about the largest star; I made it because Betelgeuse specifically was in the news.
Modern seismometers include 3 elements to determine the simultaneous movement in 3 directions: up-down, north-south,and east-west. Each direction of movement gives information about the earthquake. This animation shows both the movement of the three basic waves (P, S, and surface) and the effect of the waves on a building. The three seismograms produced by a modern seismograph station show that the P wave is more visible on the vertical component and the S wave amplitude is larger on the horizontal components.[…]
