AI Thread Summary
Astronomers have captured the sounds of the early Universe, revealing it began with a quiet whisper rather than a loud bang. Mark Whittle from the University of Virginia analyzed background radiation formed 400,000 years post-Big Bang. The ripples in this radiation resemble sound waves traveling through space. Over the first million years, the cosmic "music" evolved from a bright major chord to a somber minor chord. This research enhances our understanding of the Universe's early moments.

"Astronomers have recaptured the sounds of the early Universe showing it was born not with a bang but a quiet whisper that became a dull roar. Mark Whittle of the University of Virginia has analysed the so-called background radiation that was born 400,000 years after the Big Bang.

Ripples in the radiation are like sound waves bouncing through the cosmos. Over the first million years the music of the cosmos changed from a bright major chord to a sombre minor one..."

Thread 'Venus and Jupiter Conjunction'

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
