Citizen Scientists Discover Star-Like Object on Course to Escape Milky Way at 1 Million MPH
August 22, 2024The 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.
