More than 650 everyday citizens have become published scientific authors by volunteering with NASA projects, discovering everything from comets to exoplanets. Their contributions are now part of the permanent scientific record that will inform researchers for generations.
More than 650 everyday people who volunteered for NASA citizen science projects have become published co-authors on peer-reviewed research papers. They discovered comets, tracked auroras, and studied exoplanets from their own backyards.
A spacecraft caught a comet "switching on" a second tail as it made its closest approach to Earth on April 26. The rare cosmic light show revealed how comets create stunning dual tails when approaching the sun.
Scientists traced an interstellar comet to one of the coldest, most isolated corners of the early galaxy, offering a rare glimpse into how our universe formed billions of years ago. The cosmic visitor, possibly 11 billion years old, just gave us a window into conditions that existed before our Sun was born.
A comet from another star system is releasing enough water to fill 70 Olympic pools every day as it passes through our solar system. The rare visitor gives scientists their first chance to study materials from planetary systems far beyond our own.

A comet did something scientists have never seen: it slowed down, stopped spinning, and started rotating the opposite direction. The discovery gives us a rare chance to watch one of these ancient space rocks transform before our eyes.
The Fertitta family has reached a deal to bring professional women's basketball back to Houston after nearly two decades. The legendary Houston Comets will return in 2027 after the family purchases the Connecticut Sun.
Stargazers are in for a treat this April with a rare double comet appearance, the dazzling Lyrid meteor shower, and a full moon—all visible without expensive equipment. The best part? You can see most of these celestial wonders with just your eyes.
For the first time, astronomers watched a comet slow down, stop, and then start spinning the opposite way. The discovery reveals how dynamic and powerful these icy space wanderers really are.
A spacecraft heading to Jupiter perfectly positioned itself to film our solar system's third interstellar visitor, giving scientists an unprecedented view of a comet from another star system. Teams across the globe collaborated on this unexpected cosmic opportunity.
A mysterious visitor from beyond our solar system has been captured on camera by a Jupiter-bound spacecraft, giving scientists a rare glimpse into the cosmos beyond our neighborhood. Only three interstellar objects have ever been spotted passing through our solar system.
Scientists discovered Earth's core contains enough hydrogen to equal 45 oceans of water, suggesting our planet formed with water already inside rather than getting it from comets. This breakthrough helps solve the mystery of where Earth's water really came from.
Astronomers tracked a rare visitor from beyond our solar system as comet 3I/ATLAS passed through on a one-way journey. The James Webb Space Telescope revealed its unique composition, offering scientists an exciting glimpse into how other star systems form planets.
Astronomers discovered a rare comet that might become bright enough to see with the naked eye next spring. This comet belongs to a special family that has produced some of history's most spectacular sky shows.
NASA's planet-hunting spacecraft caught rare footage of an interstellar comet racing through our solar system, giving scientists a precious glimpse of a visitor from beyond. The 28-hour video reveals secrets about this cosmic traveler's path back to deep space.
NASA's James Webb Space Telescope just answered a puzzle that has stumped astronomers for decades: how do frozen comets billions of miles from the sun contain crystals that need scorching heat to form? The answer reveals a cosmic delivery system more spectacular than anyone imagined.
Amateur astronomers with smart telescopes are joining NASA missions to track dangerous asteroids and discover comets. One citizen scientist in South Africa captured crucial data during NASA's asteroid deflection test.
NASA's James Webb Space Telescope captured a young star creating crystals in blazing heat and flinging them billions of miles into its icy outer disk. This cosmic discovery reveals how comets at the edge of our solar system got their mysterious building blocks. #
After a seven-month journey through our solar system, interstellar comet 3I/ATLAS has faded from view, leaving astronomers with treasure trove of data from one of the most-studied comets in history. The ancient visitor from another star system is now heading back into deep space, reminding us of the wonders waiting beyond our cosmic neighborhood.
NASA's James Webb Space Telescope just explained how heat-formed crystals end up in comets billions of miles from the sun. The answer involves baby stars shooting cosmic minerals across space like a highway.
