@AstroBalrog In the coming months YFF will announce ways for interested people to help. That will be announced on here and also on the Yerkes FB page. Thank you very much for your interest.

What will become of @YerkesObs in Wisconsin? The University of Chicago is reviewing proposals to off-load the facility and property. Read about the latest developments https://t.co/Vy9bM5luPU and the impressive history of the observatory https://t.co/uL27VpHKIE

Astronomer George Ellery Hale was born 150 years ago today! He discovered sunspot magnetism & led @YerkesObs, @MtWilsonObs, @Caltech, @CarnegieAstro, @TheHuntington, @theNASciences & @ICSUnews. In commemoration, we’ve digitized 100,000 pages of his papers: https://t.co/WiVK3LO2en

Born #OTD 1868 in Chicago, George Ellerly Hale was an astrophysicist who built four world-class observatories, including @YerkesObs in Wisconsin and @MtWilsonObs in California #histSTM

Hale's measurements of sunspots taught us fundamental things about stars, which eventually led astronomers to realize that there is an order to the way stars work, explains @newtomato showing off a diagram that she says is like "the periodic table of stars."

.@newtomato explains how astronomers use spectroscopy to understand what the light from distant objects can tell us about their makeup. Our founder, George Ellery Hale, studied spectra of the Sun.

At 14, young George Ellery Hale convinced his dad that he needed a telescope to track the transit of Venus and participate in a global project allowed scientists to determine the distance from the Earth to the Sun.

George Ellery Hale's scientific legacy underpins all of modern astrophysics says @newtomato as we celebrate his sesquicentennial this week.

[Carnegie Astronomy @CarnegieAstro]

Tonight @newtomato will teach us about the science of George Ellery Hale, who we often talk about as our founder and a builder of telescopes, but don't discuss enough as someone with an incredible research legacy in his own right.
