Water discovered on exoplanet K2-18b in 'Goldilocks Zone'

Scientists say it might even rain on the exoplanet, dubbed K2-18b.

  • Two new studies, from independent teams of researchers, say that it's extremely likely that the exoplanet's atmosphere contains water vapor.
  • Scientists are able to make these kinds of determinations by pointing telescopes at distant stars and measuring subtle changes in light as exoplanets pass in front of the star.
  • Scientists will likely get a better look at K2-18b when NASA launches the powerful James Webb Space Telescope in 2021.

What NASA can teach us about education reform

If teachers weren't taught to fear failure, could they see greater success in the mission of education?

  • Matt Candler, founder of 4.0 Schools, questions why school has stayed overwhelmingly the same the past 100 years. As a teacher, he sees the future of schools embracing mutual curiosity in both students and educators.
  • He points to the example of NASA scientists, who approach missions with the idea that failure is welcome and necessary. Failure during preparation ensures the mission will succeed when the time comes to perform.
  • Candler suggests that this idea should hold up in discussions of education reform and how teachers are trained in their approach to learning.
  • This video is supported by yes. every kid., an initiative that aims to rethink education from the ground up by connecting innovators in a shared mission to conquer "one size fits all" education reform.

  • The Amazon fires were captured by the AIRS camera on the Aqua satellite.
  • A movie clip released by NASA shows a huge cloud of CO drifting across the continent.
  • Fortunately, carbon monoxide at this altitude has little effect on air quality.
