How long will Hubble stare at these fields?
How will the lensed and distorted galaxies be de-lensed?

Please stay tuned for more Hubble Hangouts on the Frontier Fields as the project progresses. We are planning more hangouts that discuss the role of dark matter in the Frontier Fields clusters, how to get the data yourself from the Hubble archive, and much ...
