Cometa – Foto: Trifonov_Evgeniy/ iStock Comet 3I/ATLAS, the third confirmed interstellar object, began moving away from the Sun after reaching perihelion on October 29, 2025, 1.36 astronomical units away. Astronomers from around the world are preparing equipment to capture images of the visitor, from another star system, who crosses theContinue lendo
rota do 3I-ATLAS – Foto: NASA/JPL-Caltech The comet 3I/ATLAS, the third detected interstellar object, crosses the solar system without any collision risk to Earth. Astronomers launched a global observation campaign on October 21 to refine trajectory measurements. The celestial body reaches its closest approach at about 270 million kilometers fromContinue lendo
cometa – Foto: Domenichini Giuliano / Shutterstock.com The interstellar comet 3I/ATLAS, discovered in July 2025 by the ATLAS survey in Chile, exhibits early fragmentation signs due to solar thermal stress. NASA and European Space Agency (ESA) astronomers report accelerated gas and dust release as the object nears perihelion. This activityContinue lendo
3IATLAS – Foto: Jack_the_sparow/Shutterstock.com An interstellar comet, identified as 3I/ATLAS, originating from another solar system, is at risk of collapsing due to intense solar heat. Discovered in 2023, the celestial object is nearing its perihelion, the closest point to the Sun, where extreme temperatures may fragment it. Astronomers are monitoringContinue lendo
