  • Rubin Observatory to monitor the southern sky for a decade, collecting vast time-domain data and sending alerts within a minute.
  • Historic glass plates, digitized and studied via programs like DASCH, provide decades-long data for time-domain studies.
  • Historical data help tune models of black-hole systems by revealing past flares and outbursts.
  • Glass plates offer a century-long view of the sky, with some imaging data dating back to 1896.
  • Researchers calibrate multi-era data to form a long, interconnected record of celestial changes.
  • Time-domain astronomy classifies objects as transients or variables to study underlying physics.
  • The DASCH project digitizes decades of Harvard plates, enabling wide access to archival data.
  • The study emphasizes preserving glass plate archives as they can yield hidden discoveries for modern astronomy.
  • Time-domain research links past and present observations to refine cosmological understanding.

  • Latest evidence from trans-Neptunian observations suggests a warp in the Kuiper belt, hinting at a distant planet.
  • Researchers estimate a planet between Mercury and Earth could exist 100–200 AU from the Sun.
  • The supposed Planet Y could be detectable by LSST if within the Rubin Observatory’s footprint.
  • The research is published on arXiv and accepted by the Monthly Notices of the Royal Astronomical Society.
  • Planet Y's location would place it well beyond Neptune, adding to debate on planetary classification.
  • The discovery would influence whether Planet Y is recognized as a official solar system planet.
  • The Rubin Observatory LSST will play a key role in confirming Planet Y if it exists.
  • The finding hinges on a small chance (about 2%) that the warp is a fluke of solar system evolution.
  • Planet Y would have a mass between Mercury and Earth, orbiting 100–200 AU from the Sun.
