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.
NASA's James Webb Space Telescope solved a cosmic mystery by watching a young star create and fling Earth-like minerals across space. The discovery explains how frozen comets at the edge of our solar system ended up packed with crystals that form only in extreme heat.
