Webb separation from Ariane 5


video upload by European Space Agency, ESA

This real-time video shows the separation of the James Webb Space Telescope from the Ariane 5 launch vehicle and the subsequent solar array deployment.

Webb’s launch on an ESA-provided Ariane 5 rocket was performed by @arianespace on behalf of ESA from Europe’s Spaceport in French Guiana, at 12:20:07 GMT (13:20:07 CET) on 25 December 2021.

Webb separation from the Ariane 5 occurred at 12:47:14 GMT (13:47:14 CET) with solar array deployment starting 69 seconds later.

Thanks to Ariane 5’s highly precise launch trajectory Webb’s solar array was able to deploy soon after separation from the Ariane 5, capturing sunlight to power the observatory.

This video shows the view from Ariane 5’s upper stage, taken by a camera manufactured by Irish company Réaltra Space Systems Engineering.

Webb is the next great space science observatory following Hubble, designed to answer outstanding questions about the Universe and to make breakthrough discoveries in all fields of astronomy. Webb will see farther into our origins: from the formation of stars and planets, to the birth of the first galaxies in the early Universe. Webb is an international partnership between @NASA, ESA and the @Canadian Space Agency.

Jupiter North Pole Infrared Flyover


Uploaded on Apr 11, 2018 NASA

"An infrared view of Jupiter’s North Pole. The movie utilizes imagery derived from data collected by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard NASA's Juno mission. The images were obtained during Juno’s fourth pass over Jupiter. Infrared cameras are used to sense the temperature of Jupiter’s atmosphere and provide insight into how the powerful cyclones at Jupiter's poles work. In the animation, the yellow areas are warmer (or deeper into Jupiter’s atmosphere) and the dark areas are colder (or higher up in Jupiter’s atmosphere). In this picture the highest “brightness temperature” is around 260K (about -13°C) and the lowest around 190K (about -83°C). The “brightness temperature” is a measurement of the radiance, at 5 µm, traveling upward from the top of the atmosphere towards Juno, expressed in units of temperature.

Low 3-D Flyover of Jupiter’s North Pole in Infrared

Published on Apr 11, 2018

"In this animation the viewer is taken low over Jupiter’s north pole to illustrate the 3-D aspects of the region’s central cyclone and the eight cyclones that encircle it.

Titan Touchdown


Published on Jan 11, 2017 NASA Jet Propulsion Laboratory

"On Jan. 14, 2005, ESA's Huygens probe made its descent to the surface of Saturn's hazy moon, Titan. Carried to Saturn by NASA's Cassini spacecraft, Huygens made the most distant landing ever on another world, and the only landing on a body in the outer solar system. This video uses actual images taken by the probe during its two-and-a-half hour fall under its parachutes.

Huygens was a signature achievement of the international Cassini-Huygens mission, which will conclude on Sept. 15, 2017, when Cassini plunges into Saturn's atmosphere.

What Are White Holes?


Published on Oct 8, 2015 Fraser Cain

"Black holes are created when stars die catastrophically in a supernova. So what in the universe is a white hole?"

The Fermi Paradox — Where Are All The Aliens?


Published on May 6, 2015 Kurz Gesagt - In a Nutshell

"The universe is unbelievably big – trillions of stars and even more planets. Soo… there just has to be life out there, right? But where is it? Why don’t we see any aliens? Where are they? And more importantly, what does this tell us about our own fate in this gigantic and scary universe?"
