The human naked eye has an angular resolution of approximately 280 microradians [17] (μrad) (approx 0.016° or 1 minute of arc), and the ISS targets an altitude of 400 km. [18] Using basic trigonometric relations, this means that an astronaut on the ISS with 20/20 vision could potentially detect objects that are 112 m or greater in all ...
Some of the modular lenses that are known to be used on the ISS include several Nikon F and 15 Nikon Z lenses, for cameras such as the D4 and Z9. [ 21 ] [ 13 ] This includes the Nikon 24-70mm f/2.8E ED VR, the Nikkor 600mm f/4G AF-S VR ED, [ 22 ] the Nikon 800mm f/5.6E FL ED VR, and the Nikon AF-S FX TC-14E III 1.4x Teleconverter .
The German educational project "Columbus Eye – Live Imagery from the ISS in Schools", which is executed by the University of Bonn and is funded by the German Aerospace Center (DLR), aims at the implementation of the ISS live imagery and videos in a web portal. It primarily acts as a learning portal for pupils, but also serves as a free access ...

Comet Tsuchinshan-ATLAS is expected to come within approximately 44 million miles of Earth on Saturday.
The International Space Station (ISS) is a large space station that was assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada).
The comet will look like a bright fireball with a long, extended tail, said Bill Cooke, lead of NASA's Meteoroid Environment Office at the Marshall Space Flight Center in Alabama, KABC-TV reported.
Close to sunset and sunrise, bright stars like Sirius or even Canopus can be spotted with the naked eye as long as one knows the exact position in which to look. Historically, the zenith of naked-eye astronomy was the work of Tycho Brahe (1546–1601). He built an extensive observatory to make precise measurements of the heavens without any ...
