Join us online or in-person for our Public Lecture Series, which occurs on the first Tuesday of every month. Visit http://hubblesite.org/about_us/public_talks/ for links to both live and previous lectures, or join us in the Space Telescope Science Institute auditorium, 3700 San Martin Drive, Baltimore, Md., 21218. Admission is free and free parking is available in the lot across the street.
Astronomers long thought that the Smith Cloud might be a failed, starless galaxy, or gas falling into the Milky Way from intergalactic space. If either of these scenarios proved true, the cloud would contain mainly hydrogen and helium, not the heavier elements made by stars.
Hubble was used to measure the chemical composition and found heavier elements that could only come from stars. The cloud appears to have been ejected from within the Milky Way and is now boomeranging back. It will plow back into the Milky Way's disk in about 30 million years. When it does, astronomers believe it will ignite a spectacular burst of star formation, perhaps providing enough gas to make 2 million suns.
Though this settles the mystery of the Smith Cloud's origin, it raises new questions: How did the cloud get to where it is now? What calamitous event could have catapulted it from the Milky Way's disk, and how did it remain intact? The answers may be found in future research.

Join the discussion of these objects, how they are found and what they mean for galaxy formation and evolution.
Your hosts, as always, are Dr. , , and who will be speaking with scientists who use the and other instruments to study Supermassive Black Holes.
Join Dr. and as they talk with members of the on the current status of Webb and the completion of affixing the final mirror!
You'll be able to live-chat on the YouTube page when we're live and we will be live-tweeting the event on Twitter using the hash tag #HubbleHangout.

Nearly 400 years after Galileo first observed the heavens through a telescope, we continue to seek answers to age-old questions about the universe. And while the technology has evolved over the centuries, the inquiry remains essentially the same: What's out there, where did it come from, and what does it mean?
At the Space Telescope Science Institute (STScI), we're working hard to study and explain the once-unimaginable celestial phenomena now made visible by the Hubble Space Telescope's cutting-edge technology.
