Is there life on other planets in our galaxy?
On the off chance there is, are you listening? Because today, NASA will spin a song into space for the first time — The Beatles' "Across the Universe" will go into deep space at 7 p.m. ET.
Today is the 40th anniversary of the song's first recording.
Paul McCartney is happy about being beamed into space. "Amazing! Well done, NASA!" McCartney wrote in a message to the space agency. "Send my love to the aliens. All the best, Paul."
