ZARTH App: Augmented Reality Transient Hunter

  • The ZARTH app is an augmented reality mobile game designed for serious science engagement.
  • Uses the open-source Sky Map and daily data from the Zwicky Transient Facility (ZTF) telescope at Palomar Observatory.
  • ZTF scans the northern sky every two days, providing valuable data for tracking near-earth asteroids and studying supernovae.
  • Daily updates of real-time transients detected by ZTF, including flaring stars, white dwarf binaries, and more.
  • Transients ranked by rarity and importance, allowing players to compete, score points, and earn credits on leaderboards.
Transient Phenomenon:
  • Transients are astronomical events lasting from fractions of a second to weeks or years.
  • These events are typically short-lived and associated with the destruction of astrophysical objects.
