Three Solar Geophysical Probes Track Interstellar Comet 3I/ATLAS

NASA’s STEREO (Solar-Earth Relations Observatory), the NASA/ESA SOHO (Solar-Heliospheric Observatory), and NASA’s PUNCH (Corona-Heliosphere Integrating Polarimeter) missions had the extraordinary capability to observe sky regions near the Sun, enabling them to monitor 3I/ATLAS as it traversed behind the Sun from Earth’s perspective. 3I/ATLAS moves at an incredible speed of 209,000 km (130,000 miles) per hour, [...] The post Three Solar Geophysic…

Three Heliophysics Spacecraft Observe Interstellar Comet 3I/ATLAS

NASA’s STEREO (Solar Terrestrial Relations Observatory), the NASA/ESA SOHO (Solar and Heliospheric Observatory), and NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) missions have the unique ability to observe areas of the sky near the Sun, which allowed them to track 3I/ATLAS as it passed behind our Sun as seen from Earth.
