“I Mapped the Invisible”: Matteo Paz Discovers 1.5 Million Lost Space Objects
“I Mapped the Invisible”: Matteo Paz stuns scientists by discovering 1.5 million lost space objects sounds like science fiction. However, this breakthrough represents something far more significant than viral headlines suggest. Moreover, it demonstrates how artificial intelligence can revolutionize astronomical discovery. As someone who has spent years covering space science, I believe this teenager has accomplished what professional astronomers hoped machine learning could achieve: making the invisible visible.
The Breakthrough Explained: How Matteo Paz Mapped 1.5 Million Cosmic Objects
Here’s the stunning reality: Matteo (Matthew) Paz, an 18-year-old high school senior from Pasadena, California, has cataloged 1.5 million previously unidentified astronomical objects. Furthermore, these include variable stars, quasars, supernovae, and other cosmic phenomena that official catalogs missed entirely. The student compiled this discovery using NASA’s NEOWISE telescope data and custom AI processing. Consequently, professional astronomers now face new opportunities to study cosmic variability.
The timeline moves with remarkable speed. Working through Caltech’s Planet Finder Academy, Paz spent months refining his AI algorithm under the mentorship of Davy Kirkpatrick, a senior scientist at Caltech’s IPAC. Then he published his findings as a single-author paper in The Astronomical Journal. Subsequently, his work earned him the 2025 Regeneron Science Talent Search first place prize of $250,000.
Professional astronomers responded appropriately: impressed and eager to collaborate. Rather than tracking space debris as initially suggested, Paz’s discovery focuses on variable astronomical objects—celestial bodies that change in brightness over time, offering insights into stellar evolution, galactic dynamics, and cosmic phenomena.
Paz leveraged NASA’s vast NEOWISE dataset brilliantly. The retired infrared telescope spent over a decade scanning the sky, accumulating more than 200 billion data points. Where traditional analysis focused on near-Earth objects, Paz recognized the untapped potential for studying variable sources across the cosmos.
Data fusion and patience became the secret weapons. Paz built an AI pipeline to process raw infrared observations and detect minute brightness changes over time. His algorithm, trained through coursework in machine learning and advanced mathematics at Pasadena Unified’s Math Academy, could identify patterns humans would miss in such massive datasets.
The algorithm mixed classical astronomy with modern AI effectively. A sophisticated pattern recognition system flagged candidate objects showing variability signatures. Then machine learning techniques classified different types of cosmic phenomena—from eclipsing binary stars to distant quasars.
Cross-matching proved crucial for credibility. Paz compared his discoveries against existing astronomical catalogs to avoid rediscovery while identifying genuinely new objects. This methodical approach separates amateur enthusiasm from genuine scientific breakthrough.
Conservative validation prevented false discoveries. Only candidates with consistent variability patterns across multiple observations made the final catalog. That quality threshold, not flashy headlines, delivered legitimate astronomical discoveries that will advance our understanding of the universe.
Why This Discovery Matters for Astronomy and Science
A vastly expanded catalog fundamentally changes astronomical research capabilities. These 1.5 million newly identified variable objects provide unprecedented opportunities to study stellar evolution, galactic structure, and cosmic phenomena. Even conservative estimates suggest thousands of scientifically valuable discoveries within this dataset.

The methodology proves equally important as the results. Paz’s AI approach demonstrates how machine learning can extract maximum scientific value from existing astronomical archives. This technique could revolutionize how researchers analyze data from current and future space missions.
Citizen science reaches new heights when properly mentored. Paz’s success story shows what’s possible when educational institutions provide real research opportunities to motivated students. His collaboration with professional astronomers created a model for productive partnerships between academia and exceptional young talent.
The published research in The Astronomical Journal ensures peer review validation and scientific credibility. This isn’t just a media story—it’s legitimate research that will influence future astronomical studies and space mission planning.
Next Steps: Publication and Scientific Impact
The complete catalog will be released in 2025, enabling follow-up observations by facilities like the Vera Rubin Observatory and James Webb Space Telescope. Professional astronomers worldwide will have access to investigate the most promising variable sources identified by Paz’s algorithm.
Research opportunities multiply exponentially. Universities can study specific object types, test theoretical models against observed variability patterns, and develop improved detection algorithms. The methodology itself offers applications beyond astronomy to any field involving temporal data analysis.
Collaboration with Paz continues expanding. Now a paid research assistant at Caltech’s IPAC, he mentors new high school students while refining his AI techniques. This creates a sustainable model for training the next generation of astronomical researchers.
Industry applications extend beyond space science. Paz noted potential relevance to financial market analysis, atmospheric monitoring, and any domain where temporal patterns carry important information.
The Human Story: From Stargazing Child to Prize-Winning Researcher
Behind these impressive numbers stands a teenager whose passion for astronomy began with childhood visits to Caltech’s public stargazing lectures. Paz balanced demanding coursework, part-time research, and the typical challenges of high school while pursuing genuine scientific discovery.
Motivation drives everything worthwhile. Paz’s project started with curiosity about cosmic variability and evolved into systematic research under professional mentorship. His approach exemplifies how genuine interest, combined with educational opportunity and expert guidance, can produce remarkable results.
Educational preparation proved essential. Paz’s advanced mathematics background, including AP Calculus BC by eighth grade, provided the foundation for understanding both astronomical concepts and machine learning techniques. This preparation enabled him to contribute meaningfully to professional research.
The mentorship relationship with Kirkpatrick demonstrates the value of experienced scientists investing in young talent. As Kirkpatrick noted, “If I see their potential, I want to make sure that they are reaching it. I’ll do whatever I can to help them out.”
Broader Lessons for Science and Education
Quality mentorship accelerates exceptional talent. Paz’s success highlights how research institutions can nurture promising students through structured programs that provide real scientific opportunities rather than simplified demonstrations.
Open data enables breakthrough discoveries. NASA’s decision to make NEOWISE data publicly available created the foundation for Paz’s research. This demonstrates the scientific value of transparent, accessible datasets.
Interdisciplinary skills drive innovation. Paz’s combination of astronomical knowledge, mathematical sophistication, and programming expertise enabled him to tackle challenges that might stump specialists in any single field.
The verification process validates citizen science potential. Professional astronomers’ careful evaluation of Paz’s work ensures scientific integrity while recognizing legitimate contributions from non-traditional researchers.
Conclusion: Making the Invisible Visible
Matteo Paz’s discovery represents more than impressive statistics—it demonstrates how curiosity, preparation, and proper mentorship can produce genuine scientific advancement. His identification of 1.5 million variable astronomical objects expands our understanding of cosmic phenomena while proving the power of AI-assisted research.
The phrase still captures the essence perfectly: “I Mapped the Invisible.” Through systematic analysis and innovative techniques, Paz has revealed previously hidden aspects of our universe. His work establishes new standards for student-led research while opening doors for future astronomical discoveries.
As the complete catalog becomes available to researchers worldwide, we’ll likely see numerous follow-up studies investigating the most intriguing objects Paz identified. Whether studying stellar evolution, galactic dynamics, or exotic cosmic phenomena, astronomers now have 1.5 million new research targets to explore.
The real lesson extends beyond astronomy: curiosity combined with rigorous methodology remains the foundation of scientific progress. Paz has shown that age and institutional affiliation matter less than dedication, skill, and the willingness to push boundaries in pursuit of understanding our universe.
