News question: Know your cosmic microwave background?

Quiz time: This week we’re spotlighting news about the cosmic microwave background.

But first, join Fermilab News at Work in congratulating Luciano Elementi for winning last week’s quiz. The fixed distance between magnets in the electromagnetic oil spill remediation technology optimizes the “gradient” effect of the magnetic fields between the magnets. Thank you to everyone who participated.

Now, show off your knowledge of the news coming out of Fermilab in this week’s quiz. A winner will be randomly selected from all lab employees and users who submit the correct answer to today’s question by noon CT today, Oct. 24.

This week’s question: What will the half a million sensors on CMB-S4 achieve? (Hint: See “Scientists combine forces to study first light.”)

Good luck! We will announce the winner and answer next week.

Past winners are welcome to participate in the quiz each week. However, only one win per person will be recognized in any 30-day period. The winner is recognized in the following week’s quiz and rewarded with a small token.
