Citizen scientists have made headlines with a remarkable discovery of a fast-moving object estimated to be traveling at one million miles per hour, breaking free from the gravity of the Milky Way. This extraordinary find emphasizes the potential contributions of amateur astronomers working alongside NASA.
NASA has acknowledged the effort of these citizen scientists, who are part of its Backyard Worlds: Planet 9 project, effectively putting spotlight on the role of volunteers in modern scientific research. Over the years, collaborations like these have yielded thousands of significant discoveries, underscoring how everyday enthusiasts can impact the scientific community.
The object, identified as CWISE J124909.08+362116.0, was discovered by Martin Kabatnik, Thomas P. Bickle, and Dan Caselden using images captured by NASA's Wide-field Infrared Explorer (WISE) mission. Their analysis of infrared data, originally mapped between 2009 and 2011, led to this intriguing find.
CWISE is not just fast; it's on track to escape the Milky Way entirely, entering intergalactic space. This makes it the first object of its kind recorded moving away from our galaxy at such incredible speeds.
The citizen scientists employed various ground-based telescopes to validate their observations, which highlighted the object's low mass. This unusual property complicates its classification; scientists are pondering whether CWISE is merely a low-mass star or perhaps even a brown dwarf.
Brown dwarfs are substellar objects, often deemed transitional between massive gas giant planets and small stars. The newfound object's classification might offer insights about its origin and vitality, as it may potentially contain less iron than known stars and brown dwarfs observed up to now.
According to scientists, CWISE's peculiar elemental composition could mean it is relatively ancient, possibly originating from one of the early generations of stars formed after the Big Bang. Detroit-based citizen scientist Martin Kabatnik expressed his astonishment, noting, “When I first saw how fast it was moving, I was convinced it must have been reported already.”
But how did CWISE gain such momentum to escape the galaxy? There’s speculation about its past, one theory postulating it might have been part of a binary star system with a white dwarf, wherein material transfer could have triggered the white dwarf’s explosion as a supernova.
Alternatively, some scientists theorize it may have originated from a tightly-gripped cluster of stars. A close encounter with black holes may have altered its path, launching it away from any gravitational confines.
The discovery involves not just the citizen scientists but also collaboration among educators and students who played pivotal roles. Together, they authored a paper detailing their findings, which they presented to the Astrophysical Journal Letters for peer review.

NASA’s WISE telescope was operational for several years, reshaped and reactivated as NEOWISE to continue its mission from 2013 until recently. Utilizing infrared technology has allowed astronomers to detect both distant and faint celestial objects, paving the way for breakthroughs such as the discovery of CWISE.
This remarkable event rejuvenates interest not only among professionals but also among space enthusiasts worldwide. It shows how collective efforts can yield significant advancements, opening doors to new understandings of our universe.
The repercussions of this find extend beyond its immediate scientific interest. It could lead to forthcoming inquiries and potentially reshape long-held beliefs about stellar evolution and the scales of the universe.
For NASA and the academic community, this discovery marks another success story where citizen engagement leads to exceptional insights. It stands as proof of how valuable public participation can be, igniting curiosity about space exploration.
While with every find there are more questions than answers, the excitement surrounding CWISE carries the promise of future exploration. Citizen scientists and professional astronomers alike are eager to unravel the mysteries hidden within this thrilling discovery.
So, what's next? With CWISE shifting rapidly through the cosmos, astronomers will have the opportunity to analyze its unique properties through upcoming observational campaigns. The world will be watching closely.
