These are solar sounds generated from 40 days of the Solar and Heliospheric Observatory’s (SOHO) Michelson Doppler Imager (MDI) data and processed by A. Kosovichev. He followed the following steps to create these sounds. To begin, he used doppler velocity data that had been averaged over the solar disc, leaving only modes with low angular degrees (l = 0, 1, 2). Later processing eliminated several false spots, instrument tuning, and spacecraft motion effects. Then, Kosovichev used a 3 mHz filter to isolate pure sound waves from instrument noise and supergranulation. Finally, he scaled the data (sped it up by a factor of 42,000 to get it within the audible human-hearing range (kHz)) and interpolated over the missing data.

What the James Webb Space Telescope will find is still a mystery. Will there be an answer? Will there be further queries? There is no doubt about it: Our history is one long quest for knowledge. #Nasa #JamesWebbSpacetelescope #spacetelescope #sapcemission

On Dec. 24, 1968, Apollo 8 astronauts Frank Borman, Jim Lovell, and Bill Anders became the first humans to orbit the Moon, and the first to witness the magnificent sight called "Earthrise." NASA’s Chief Scientist and Senior Climate Advisor Dr. Katherine Calvin sat down with Bill Anders to discuss the historic Earthrise photo.
