Using data from the Gaia space telescope and LAMOST, Keith Hawkins created a map of metallicity in the Milky Way.

His map confirms the presence of spiral arms and reveals previously uncharted regions of our galaxy.

The Gaia space telescope provides the most precise and comprehensive survey of the Milky Way to date.

With data on positions and chemical makeup of billions of stars, astronomers can conduct chemical cartography at a galactic scale.

Gaia's observations have allowed researchers to expand their study from thousands to billions of objects, revolutionizing our knowledge.

By understanding the fundamental properties of the Milky Way, we can apply those lessons to other galaxies and the universe as a whole.

Eunice Newton Foote published an article in 1856 that predates John Tyndall's conclusions on the greenhouse effect.

Her experiment demonstrated that air with high levels of carbon dioxide became much more heated when exposed to the sun's rays.

Foote's contributions have been rediscovered, recognizing her as an important early researcher on the greenhouse effect.

Google Doodle commemorated Eunice Newton Foote's 204th birthday, bringing attention to her pioneering work.
