The interstellar object 3I/ATLAS has entered a new observational phase after passing perihelion. Recent images reveal that the glowing halo surrounding the object has shifted in color — from red to green — prompting renewed scientific interest. In a recent article, Harvard astrophysicist Avi Loeb reviewed these observations and explained what the color change may reveal about the physical processes taking place around 3I/ATLAS.

AI translation has become a default tool in business. As convenience increases, however, there are more situations where “it’s useful” alone is no longer enough as a basis for decision-making. When a message is released externally, the true cost is often not mistranslation itself, but trust and responsibility. This article explores how far AI translation should be trusted—by examining the structure of judgment and accountability that humans still carry in real-world trans

Japan’s X-ray astronomy satellite XRISM, developed by JAXA in collaboration with NASA, has achieved a groundbreaking milestone:the world’s first X-ray detection from an interstellar object, 3I/ATLAS. Using its wide-field soft X-ray imager Xtend, XRISM captured a faint X-ray glow stretching nearly 400,000 kilometers from the object—an observation that opens a new window into the physics of interstellar bodies.

On November 19, 2025, NASA released several special feature articles on interstellar comet 3I/ATLAS in a single day. In total: five articles. Together, they describe a “solar system–wide tracking campaign” that mobilizes NASA’s full observational assets — from STEREO, SOHO, PUNCH, Lucy, and other spacecraft, to multiple planetary missions and deep-space observatories far from Earth. 3I/ATLAS is only the third interstellar comet ever observed in history. Once it leaves the

A new and surprising discovery has been made about the interstellar object 3I/ATLAS. According to the latest analysis by Professor Avi Loeb, 3I/ATLAS will pass extremely close to a special area around Jupiter called the Hill sphere — with almost perfect accuracy. This level of precision is so exact that it is difficult to think it happened by accident. Let’s break down the story in simple English so anyone — including middle school students — can understand what is hap
