Citizen Scientists Discover Star-Like Object on Course to Escape Milky Way at 1 Million MPH
  • The newly discovered celestial object, CWISE J124909.08+362116.0, was identified by citizen scientists Martin Kabatnik, Thomas P. Bickle, and Dan Caselden through NASA's Backyard Worlds: Planet 9 project.

  • CWISE J1249 is traveling at an extraordinary speed of one million miles per hour, indicating it is on a trajectory to escape the Milky Way galaxy.

  • Follow-up observations from various telescopes confirmed the object's remarkable speed and trajectory, suggesting it could indeed leave the Milky Way.

  • This object is notable as it is the first known star or star-like object with a mass similar to or less than that of a star moving at such high speeds.

  • The exact classification of CWISE J1249 remains uncertain, as it is approximately 400 light-years away, complicating efforts to determine if it undergoes hydrogen fusion.

  • Experts are debating whether CWISE J1249 is a low-mass star or a brown dwarf, given its low mass and unique characteristics.

  • Researchers believe CWISE J1249 is quite old and likely originated from one of the first generations of stars in the galaxy.

  • There are theories suggesting that CWISE J1249 could have originated from a binary system with a white dwarf or been expelled from a globular cluster due to black hole interactions.

  • Scientists are eager to analyze CWISE J1249's elemental composition to gain insights into its unusual speed and origins.

  • Citizen scientists have previously contributed to significant discoveries, such as the identification of the Jupiter-like planet TOI-2180 b, showcasing the power of public involvement in astronomical research.

  • The findings regarding CWISE J1249 are set to be published in the Astrophysical Journal Letters, highlighting the collaboration between amateur astronomers and professional scientists.

  • The concept of citizen science, which dates back to the 19th century, continues to play a vital role in modern astronomical discoveries, utilizing the collective computing power of volunteers.
