"Twitter for the Universe: A new way to follow the stars."
SkyWatch allows astronomers to subscribe to real-time event notifications, enabling them to conduct immediate observations after celestial events.
During the 2014 NASA International Space Apps Challenge, the team built a prototypical application geared for use by the general public. The application tapped into NASA’s Gamma-ray Coordinates Network and presented the user with a real-time feed of everything the network was capturing in the Universe.
They called it Twitter for the Universe: A new way to follow the stars. SkyWatch was the 2014 Global Winner for Best Use of Data.

The team decided to continue to work on their award-winning application. However, in trying to connect new data sources into SkyWatch, they realized there was a fundamental problem in the field. Data sources (mostly outside of NASA) seemed to be siloed; difficult to access; incompatible; and downright ugly.
They understood that it was an ambitious and lofty goal. Nonetheless, if they made a long-term game plan, and worked away slowly and carefully at each problem, there would be an opportunity to at least make a dent. Currently, they are working on tools for time-domain astronomy, the field in which astronomy is studied in real-time and on time scales.
SkyWatch currently access NASA data through the Gamma-ray Coordinates Network. They plan to incorporate more data sources into the product this fall. SkyWatch has been in private beta testing since May 2015.
