Is the solar system an interstellar highway, with cosmic objects speeding past at warp speeds without human notice? That’s ...

Scientists at ESA have spotted A11pl3Z, a possible interstellar object near Jupiter. Though it’s heading towards Earth, experts say it poses no threat and will pass Mars instead.

Scientists expect A11pl3Z to approach Mars next October, at a distance of 55 million km, before passing close to Earth in December at a safe distance of about 360 million km.

Another interpretation of the data, according to Loeb, could suggest that A11pl3Z is smaller than these estimates, but a plume of gas and dust are creating the illusion of a much larger object ...

The object, dubbed "A11pl3Z" or "3I/ATLAS," spans approximately 25 miles, Josep Trigo-Rodriguez, as astrophysicist at the Institute of Space Sciences near Barcelona, Spain, told The Associated Press.

Es demasiado pronto para saber si el objeto, designado por ahora como A11pl3Z, es un asteroide rocoso o un cometa helado, o qué tan grande y de qué forma es. Se necesitan más observaciones para ...

The object, initially designated A11pl3Z, was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Chile. NASA and other observatories later traced its path back to June 14 ...

It's too soon to know whether the object, designated for now as A11pl3Z, is a rocky asteroid or a icy comet, or how big and what shape it is. More observations are needed to confirm its origins.

“ESA’s Planetary Defenders are observing the object, provisionally known as #A11pl3Z, right now using telescopes around the world,” the European Space Agency said in a social media post on Wednesday.
