Science News - In the midst of a pandemic that has brought so much worry and loss, it’s natural to want to help — to do some small part to solve a problem, to counter pain, or to, importantly, remind others that there is beauty and wonder in the world. Scientists have long been doing just that. Many are chasing answers to the myriad challenges that people face every day, and revealing the rewards in the pursuit of knowledge itself. It’s in that spirit that we present this year’s SN 10: Scientists to Watch.

The event, dubbed GW170817, was also the first of any kind seen in both gravitational waves and light waves.
