Introduction
Determining whether observations captured by a telescope situated hundreds of thousands of miles away reflect genuine celestial phenomena presents a persistent challenge for researchers. A newly introduced citizen science initiative, Artifact InSPECtor, invites individuals worldwide to explore this process. Through participation, members of the public can directly assist major international space missions, including Euclid and the upcoming Nancy Grace Roman Space Telescope, in resolving fundamental inquiries regarding the cosmos.
The project demonstrates that contributors of virtually any age can make meaningful contributions to astrophysical research. Following a trial run, nine-year-old participant Maeve F. noted the unique value of helping instruct automated systems in new capabilities. Volunteers learn to train artificial intelligence models to eliminate persistent errors and flaws found within raw astronomical datasets.
What Happened
Modern astrophysical observatories rely heavily on specialized instruments known as spectrographs to analyze light gathered from millions of distant galaxies. Operating similarly to a prism, a spectrograph divides incoming starlight into a distinct spectrum of colors. Astronomers examine these spectral patterns to determine the distance of individual galaxies, identify their stellar populations, and gather data concerning the supermassive black holes located at their centers.
However, raw telescope telemetry frequently contains various "artifacts," which serve as a collective term for signals generated by non-astronomical sources rather than legitimate stars or galaxies. These distortions typically stem from stray light reflecting off internal housing structures, high-energy cosmic rays striking detector arrays, or minor electronic and camera anomalies. Such interference is comparable to a smudge obscuring a smartphone camera lens or sunlight creating unwanted glare in a photograph.
Background
The European Space Agency constructed the Euclid space telescope with vital engineering and scientific support provided by NASA to survey millions of distant galaxies. This powerful observatory will soon operate alongside NASA's Nancy Grace Roman Space Telescope, which will capture a comparable volume of deep-space imagery across different cosmic densities and distances. Together, these complementary space missions aim to investigate the rapid expansion of the universe and dark energy, the elusive phenomenon driving this accelerated expansion.
Astronomers have developed specialized artificial intelligence systems designed to detect and eliminate these disruptive artifacts automatically, functioning much like facial recognition software on consumer mobile devices. Nevertheless, identifying anomalies within telemetry produced by newly deployed instruments remains difficult for machine learning models, leading to frequent classification errors. Addressing this limitation requires human oversight to refine how algorithms process incoming data.

Impact
Citizen scientists participating in Artifact InSPECtor examine authentic space telescope telemetry sourced from Euclid, with integration for the Nancy Grace Roman Space Telescope scheduled to begin in early 2027. Volunteers receive training to accurately spot and categorize structural flaws within these complex datasets. The verified assessments produced by participants are subsequently utilized to upgrade the guiding instructions and parameters of the underlying artificial intelligence software.
