Frontier Fields: Pushing the Limits of the Hubble Space Telescope

Posted by

A collaboration of astronomers are poised to make observations with the Hubble Space Telescope that will provide us with the deepest views we’ve ever had of the cosmos and give us a glimpse of what the James Webb Space Telescope will routinely provide us.

Known as the Frontier Fields survey, this revolutionary deep field program will combine the power of the Hubble Space Telescope with the natural gravitational telescopes of high-magnification clusters of galaxies. Using both the Wide Field Camera 3 and Advanced Camera for Surveys in parallel, HST will produce the deepest observations of clusters and their lensed galaxies ever obtained, and the second-deepest observations of blank fields (located near the clusters).

These images will reveal distant galaxy populations ~10-100 times fainter than any previously observed, improve our statistical understanding of galaxies during the epoch of reionization, and provide unprecedented measurements of the dark matter within massive clusters.

The Frontier Field Survey will be pushing the limits of our beloved space telescope, making it more powerful than ever before, and providing us with some of the most important images ever taken.

Hubble Releases New Comet ISON Observations

Posted by

The Space Telescope Science Institute has released new observations of Comet ISON taken with the #Hubble Space Telescope. Here is our hangout, coinciding with the news release of this data, to discuss these observations and the latest about Comet ISON.

* Has ISON gotten brighter?
* Is it breaking up?
* Is it sprouting jets?
* Will it survive perihelion?

Please join +Tony Darnell and +Scott Lewis, along with +Bonnie Meinke, +Max Mutchler, +Zolt Levay, +Jian-Yang Li as they discuss these topics and your questions and comments about this oncoming comet.
