Hello Everyone, I would like to let you all know we have surpassed the 50% mark for our fundraising goal! We could not have done it without you all, Thank you! here is a message from Professor Newberg: "I would like to personally thank each and every MilkyWay@home supporter who has helped us to raise $21,843.97 towards our goal of $40,480 to keep up operations through summer 2015. So far, 324 people have sent money by credit card, Paypal, and check to support our work of tracing tidal streams in the Milky Way halo and using them to determine the location of dark matter. We have received donations from $0.23 to $5000 (Wow!), and sent out 36 fabulous T-shirts to donors. Some of you have included really wonderful notes along with your donations, that I have really appreciated. Already, your donations have made it possible to offer Jake Weiss his co-op job for fall 2014, we know we will be able to continue to publish our papers in highly cited journals for the next year, and graduate student Sidd Shelton has his summer salary funded. This puts in a much, much better position than we were two weeks ago. Additional donations will fund conference travel (so we can tell other scientists about our findings, and get new ideas) and undergraduate student summer salary. Undergraduate research have in recent years been the driver behind MilkyWay@home software development, but to continue that they need summer support and opportunities for professional travel. Thank you all, really, for your continued support of MilkyWay@home. Sincerely, Prof. Heidi Jo Newberg" Cheers, -Sidd
