From Slooh:

WASHINGTON DEPOT, CT - October 23rd, 2019

On Monday, November 11th, starting at 4:30 AM PST | 7:30 AM EST | 12:30UTC, Slooh will livestream the rare and spectacular Transit of Mercury from its flagship observatory at the Institute of Astrophysics of the Canary Islands. The next opportunity to witness a transit of Mercury will be in 2032 - so this opportunity should not be missed!

Slooh will broadcast live feeds of the Transit of Mercury from its high altitude observatory in the Canary Islands and from its partner observatories in Sharjah, Europe, the USA, and South America. The event will be hosted by Slooh Astronomer Paul Cox, who will be joined by our team of astronomical experts who will discuss Mercury, the Sun, and planetary transits. The team will be discussing the phenomena as viewers snap their own images from the live streams using Slooh’s StarShare Camera. The team will also discuss the importance of planetary transits in history and why major expeditions to observe them were organized at great expense during the 1700s.

Slooh's Chief Astronomical Officer, Paul Cox, said: "This is THE astronomical event of 2019 - and we won’t see another planetary transit until 2032! It’s magical to watch the tiny, hot rocky planet cross the face of the Sun - it's a perfect illustration of celestial mechanics in action.” On what viewers will see, Cox said: “We’ll be using Slooh’s highly specialised solar telescope to capture the entire transit and we could see some extraordinary solar features such as huge plumes of superheated plasma spewing out from the Sun’s limb as Mercury transits the face of our local star."

Bob Berman, show guest and host of Slooh’s “Strange Universe” club said “Only three celestial objects in the entire universe pass predictably in front of the Sun, and it's always a fascinating event. When Mercury does it -- 13 times each century -- special telescopes are needed to see it. It's very exciting that Slooh, which has the most ideal equipment, is making this event available for the world to see.”

Slooh members can use our StarShare Camera to snap images from the live feeds and use our new chat feature at slooh.com to ask questions during the show.

Slooh recently launched their new activity Quests and chat tools, which are features of its new website, developed with funding support from the National Science Foundation, and featuring new education products for students to learn to explore space via Slooh’s global network of online telescopes.
