Giant object from deep space spotted blazing through our solar system
The visitor from the stars, designated 3I/Atlas by the International Astronomical Union's Minor Planet Centre, is likely the largest yet detected. It has been classified as a comet.
'The fact that we see some fuzziness suggests that it is mostly ice rather than mostly rock,' Jonathan McDowell, an astronomer at the Harvard-Smithsonian Centre for Astrophysics, said.
Originally known as A11pl3Z before it was confirmed to be of interstellar origin, the object poses no threat to Earth, said Richard Moissl, head of planetary defence at the European Space Agency.
'It will fly deep through the solar system, passing just inside the orbit of Mars,' he said, 'but will not hit our neighbouring planet, he said.
Excited astronomers were still refining their calculations, but the object appears to be zooming more than 60km (37 miles) a second.

French study reveals surprising microplastic levels in glass bottles
QUESTION: What did the ANSES study find regarding microplastics in drinks? A study by France's food safety agency, ANSES, found that drinks such as water, soda, beer, and wine in glass bottles contain more microplastics than those in plastic bottles. The researchers found an average of around 100 microplastic particles per litre in glass bottles of soft drinks, lemonade, iced tea and beer. That was five to 50 times higher than the rate detected in plastic bottles or metal cans. 'We expected the opposite result,' said PhD student Iseline Chaib, who conducted the research. They observed that the particles emerging from the samples had the same shape, colour and polymer composition, indicating they were the same type of plastic as the paint on the caps of the glass bottles. The paint on the caps also had 'tiny scratches, invisible to the naked eye, probably due to friction between the caps when they were stored,' the agency said. This could then 'release particles onto the surface of the caps', it added.

Giant object from deep space spotted blazing through our solar system
Astronomers on Wednesday confirmed the discovery of an interstellar object racing through our solar system – only the third ever spotted, though scientists suspect many more may slip past unnoticed.

'Interstellar object' spotted in Solar System
'Interstellar object' spotted in Solar System Astronomers believe a 10-20km-wide mass may be the third interstellar object to be observed in our Solar System. File photo: Reuters An object that appears to be from beyond our Solar System has been spotted hurtling towards the Sun, which if confirmed would be the third visitor from the stars ever detected, the European Space Agency said on Wednesday. The object, which is currently being referred to as A11pl3Z, poses no threat to Earth, the ESA's planetary defence head Richard Moissl told AFP. "It will fly deep through the Solar System, passing just inside the orbit of Mars," but will not hit our neighbouring planet, he said. Excited astronomers are still refining their calculations, but the object appears to be zooming more than 60 kilometres a second. This would mean it is not bound by the Sun's orbit, unlike comets and asteroids, which all originate from within the Solar System. Its trajectory also "means it's not orbiting our star, but coming from interstellar space and flying off to there again," Moissl said. "We are not 100 percent certain at the moment, but anything else would be a surprise," he added. Official confirmation is expected to come from the International Astronomical Union's Minor Planet Center, which has recorded more than 100 observations of the object so far. The NASA-funded ATLAS survey in Hawaii first discovered the object on Tuesday, US astronomer David Rankin wrote on the social media platform Bluesky. Professional and amateur astronomers across the world then searched through past telescope data, tracing its trajectory back to at least June 14. The object is currently estimated to be roughly 10-20 kilometres wide, Moissl said. But the object could be smaller if it is made out of ice, which reflects more light. "It will get brighter and closer to the Sun until late October and then still be observable (by telescope) until next year," Moissl said. It would be the third time humanity has detected something coming from the stars. The first, 'Oumuamua, was discovered in 2017. It was so strange that at least one prominent scientist became convinced it was an alien vessel – though this has since been dismissed by further research. Our second interstellar visitor, 2I/Borisov, was spotted in 2019. Mark Norris, an astronomer at the UK's University of Central Lancashire, told AFP that the new object appears to be "moving considerably faster than the other two extra-solar objects that we previously discovered." He pointed to modelling estimating that there could be as many 10,000 interstellar objects drifting through the Solar System at any given time, though most would be smaller than the newly discovered object. If true, this suggests that the newly online Vera C. Rubin Observatory in Chile could soon be finding these dim interstellar visitors every month, Norris said. (AFP)
