Hubble Views Moon to Study Earth
Taking advantage of the total lunar eclipse of January 2019, astronomers, using NASA’s Hubble Space Telescope, have measured the amount of ozone in Earth’s atmosphere. The method used serves as a proxy for how they will observe...

The Ozone Layer - Part 1
Learn about the two main layers of the atmosphere: the troposphere and the stratosphere. The troposphere is full of weather and ‘bad’ ozone, and above that, is the stratosphere, where ‘good’ ozone protects us against dangerous UV light....

ATom Mission interview clips — Tom Ryerson
A flat line of data may not look interesting, but Tom Ryerson of NOAA with the #EarthExpedition ATom mission explains how it could reveal how tropospheric ozone is removed from the atmosphere. The ATom mission aboard NASA’s DC-8 flying...

Weather Things: Weather Cycles
The orbit of Earth on a tilted axis around the sun leads to the seasons. The resulting change of angle of the sun, and length of day controls how warm we get at different times of the year. With those changes in seasons come changes in...
