Astrophotographer Took a Photo of the International Space Station So Detailed You Can See Spacewalking AstronautsFrom Germany to space, with love. Last Wednesday (March 23), astrophotographer Sebastian Voltmer captured a snapshot of spacewalk action from the ground. Using a Celestron 11-inch EdgeHD telescope on a GM2000 HPS mount and an ASI290 planetary camera to get the shot, Voltmer caught the image in the sky from Sankt Wendel, Germany. The picture was of NASA astronaut Raja Chari and the European Space Agency's Matthias Maurer who were performing a variety of maintenance tasks at the exterior of the International Space Station. Voltmer managed to capture the rare sighting shortly after sunset. Interestingly, Maurer’s hometown also happens to be Sankt Wendel, Germany, making the entire circumstance doubly amazing.Image: Sebastian Voltmer#InternationalSpaceStation #astrophotography #telescope #astronaut #NASA #spacewalk

What to Expect from the World's Largest Space TelescopeThe James Webb Space Telescope is set to launch on December 18, 2021. It was designed as a replacement for the Hubble Space Telescope. Although this new telescope is eleven years late and cost ten times as much as projected, it will be well worth it for astronomers and other scientists. The images we've seen from Hubble are simply amazing, and grew our knowledge of the cosmos exponentially. Yet astronomers have significantly greater hopes for Webb. Here's why:Hubble's reflecting mirror is 7.8 feet across. The Webb mirror is 21.3 feet across, which will give it six times the area, and the corresponding ability to collect light. Hubble collects light in the visible spectrum, plus has a limited ability to collect infrared light. Webb is primarily an infrared collector, which will allow it to see across vast galaxies, and collect light going further back in time -billions of years. Infrared light will also enable Webb to see exoplanets with the interference of the stars they are orbiting.While Hubble orbits earth at a distance of 340 miles, Webb will be deployed at a million miles away. An article at Vox expands on the advantages of the James Webb Space Telescope, and gives us a glimpse at some of the things scientists expect to see in the coming years.  -via Kottke (Image credit: NASA's James Webb Space Telescope) #telescope #JamesWebbSpaceTelescope #space #spaceexploration

The Results Of Amateur Astronomer’s Attempt To Point A Telescope To Jupiter For 6 HoursAmateur astronomer Deddy Dayag has managed to capture astonishing footage of Jupiter with his equipment!For six hours, Dayag pointed his telescope to the sky in order to capture a recording of the planet. The 16-second video is composed of 452,000 frames! The hobbyist’s camera took 1000 frames per minute. After editing and compiling all the footage from his telescope’s ‘watch duty,’ the frames were condensed into the short clip below. #Space #Planets #Jupiter #Astronomy #PlanetWatching #telescope
