A mysterious object from interstellar space is screaming through the solar system right now, and is expected to rip past several planets over the coming months. Astronomers have been fascinated by the unusual apparition, broadly coming to the conclusion that it's a comet, a possibly enormous wad of ice and dust particles. As it approaches its closest point to our Sun, its activity is steadily picking up, meaning that it's shedding more and more gases and dust, giving it a growing tail. But ac...| Futurism
As interstellar object 3I/ATLAS approaches its closest point to the Sun next month, astronomers are watching as the mysterious object continues to defy expectations. The object, which is largely believed to be a comet that came to us from outside the solar system, has been observed as it changes shape. Its tail has grown longer and its coma, a large atmosphere of gas and dust that surrounds a comet's nucleus, becomes more pronounced, expected characteristics from a comet ripping by the Sun at...| Futurism
Ever since a mysterious interstellar object, dubbed 3I/ATLAS, was first spotted screaming into our solar system, famed Harvard astrophysicist Avi Loeb has been raising the possibility that the interstellar interloper is an "extraterrestrial artifact" that was sent to us by an intelligent race. The object will make its closest pass of the Sun next month, coming surprisingly close to Mars and Jupiter as well. To Loeb, it's a magnificent opportunity to have a closer look. He called on NASA to tu...| Futurism
When NASA’s ATLAS survey first spotted the interstellar comet 3I/ATLAS in July 2025, astronomers recognized it as a rare and intriguing visitor from beyond our solar system. Yet, with each new observation, 3I/ATLAS has only grown stranger, upending expectations of what an interstellar traveler should look like or how it should behave. In the past two months, the world’s most powerful telescopes, including Hubble, JWST, SPHEREx, and TESS, have locked onto 3I/ATLAS, revealing that this in...| The Debrief
