A recently released image from the Hubble Space Telescope (HST) captures a rare moment: when two galaxies merge and set off a burst of star formation. Prof. Keren Sharon was part of the team that identified the unique object and is still working to fully understand what is happening.
There are several "hubblecast” videos to go along with the European Space Agency's press release.
For those who want to dig deeper, there are two publications associated with this news release: “A Thirty Kiloparsec Chain of "Beads on a String" Star Formation Between Two Merging Early Type Galaxies in the Core of a Strong-Lensing Galaxy Cluster” by Trembley et. al, and “The Mass Distribution of the Strong Lensing Cluster SDSS J1531+3414” by Sharon et. al.
Also, stay tuned for more: Prof. Sharon and her collaborators will be doing a “Hubble Hangout” a 3 PM on 7 August!
