The ESA Space Debris Office is closely following the reentry of the Cosmos (Kosmos) 482 Venus descent craft and currently expects the object to reenter Earth's atmosphere on Sat. 10 May 06:37 UTC (08:37 CEST) ± 3.28h. Some background and updated information at:…
This column of red and purple light is a phenomenon known as a red sprite. It was captured in 2017 by a cloud camera at Gemini North, one half of the International @GeminiObs, operated by @NSF @NOIRLabastro. 📷: International Gemini Observatory/NOIRLab/NSF/AURA/A. Smith
Sunrise, sunset Swiftly flows the lunar day Thanks to cameras aboard @Firefly_Space's Blue Ghost lander, we've seen the start and end of a day on the Moon. Check out the science we did in between: go.nasa.gov/3DCuLrS
First image ever of a total Lunar eclipse observed from the Moon’s surface on March 14 : Earth, four times the Sun’s apparent diameter in the Moon’s sky, is blocking the light of the Sun as seen from @Firefly_Space’s Blue Ghost lander operating in Mare Crisium.
A lunar eclipse — as seen from the Moon. Today, @Firefly_Space's Blue Ghost lander was able to capture something extremely special from the surface of the Moon: the Earth blocking the light of the Sun, creating a bright ring of light in the lunar sky.
63.7 km wide crater #Aglaonike in the northwestern part of Lavinia Planitia on #Venus. The height of the crater rim above the surrounding terrain gives an indication of the lithospheric properties and the thickness of the post-impact infill. #ESAEnVision's #VenSAR will…
