#3IATLAS update! We've just pinpointed the comet's path with 10 times more accuracy, using data from our #ExoMars Trace Gas Orbiter spacecraft (it's the first time an official comet trajectory is determined using data from another planet). 😎 https://www.esa.int/Space_Safety/Planetary_Defence/ESA_pinpoints_3I_ATLAS_s_path_with_data_from_Mars | ESA - European Space Agency

Comet Lemmon reached its closest distance to the sun on November 8th! Here’s a timelapse as I tracked the comet from Joshua Tree National Park! There is currently only a short window to see the comet after sunset when it gets dark enough as the comet goes below the horizon about 2 hours after sunset. #comet #cometlemmon #astrophotography #timelapsevideo #joshuatreenationalpark #nightskyphotography #losangelesgrammers | Henry Jun Wah Lee / Evosia Studios

Comet Leonard and the globular cluster M3 look similar in size from Earth — but they couldn’t be more different. One sits just 33,000 light-years away, the other is a dense sphere of 500,000 stars stretching 220 light-years across and nearly 8 billion years old. ✨ Astrophotographer @stanmoniz captured this stunning lineup over California, revealing two cosmic objects separated by unimaginable distance yet sharing the same patch of sky. #space #outerspace | The Galactic Void
