A 17-year-old intern at NASA's Goddard Space Flight Center discovered a new exoplanet orbiting two stars, NASA announced this week.
Why it matters: This planet, dubbed "TOI 1338 b" is located in a system 1,300 light-years away from Earth, and it is the first world orbiting two stars that's been seen by NASA's recently launched Transiting Exoplanet Survey Satellite (TESS).
A magnitude 5.9 earthquake struck Puerto Rico on Saturday around 8:54 a.m., about 8 miles south of Indios, marking the most powerful tremor since a magnitude 6.4 quake hit the island on Tuesday, according to the United States Geological Survey.
What's happening: Multiple intermittent earthquakes affected the island on Friday and into Saturday morning, including a 5.2 magnitude earthquake Friday following quakes earlier this week that killed at least one person, caused widespread power outages and displaced nearly 2,000 people.
