ASKAP J1832: Scientists discovers mysterious pulsating star in space

BBC News06-06-2025
Scientists say they've spotted a mysterious object in space behaving in a very strange way.The star, which has been named ASKAP J1832, is acting unlike anything seen before, according to Nasa experts.Located around 15,000 light years from Earth, it is pulsing every 44 minutes.What's even more strange is that it is doing it with both radio waves and X-rays.
What did scientists find?
A team of astronomers looked at data from Nasa's space-based Chandra X-ray Observatory and the Square Kilometre Array Pathfinder (ASKAP) radio telescope in Australia to study the discovered object, which has been called ASKAP J1832.They found that the star belongs to a class of objects called "long period radio transients" - that means it sends out radio waves of different levels over tens of minutes - in this case every 44 minutes.However, they also found that it is also sending X-rays every 44 minutes too.According to Nasa, this combination of factors is "unlike anything astronomers have seen in the Milky Way galaxy."Experts are trying to work out what type of object ASKAP J1832, however they think it might be one of two things.It could be a magnetar - which is a neutron star with an extremely strong magnetic field, with an age of more than half a million years.Or it could also be possibly an unusual white dwarf star which has a companion star.

Watch: Mysterious interstellar object passes through our solar system

A mysterious interstellar object, named 3I/ATLAS, has been observed travelling through our solar system. Images from the Canary Islands Institute of Physics captured the object, which Nasa has confirmed is only the third interstellar object ever seen. Nasa said that 3I/ATLAS will pass Earth at a distance of approximately 150 million miles, posing no threat to the planet. The object is expected to be visible to ground-based telescopes through September, reappearing in early December for its closest approach to Earth. Watch the video in full above.

Watch as mysterious ‘interstellar' object passes through the solar system

This is the moment a mysterious object that has come from interstellar space was spotted travelling through our solar system. Images shared by the Canary Islands Institute of Physics on Thursday (3 July) shows the entity weaving through stars as it heads towards our sun. Nasa scientists have confirmed that the object, known as 3I/ATLAS, is an 'interstellar object' - only the third of its kind ever seen. The space agency confirmed that it will travel past the Earth at a distance of about 150 million miles, posing no threat to the planet. It should be visible to ground-based telescopes through September, after which it will pass too close to the Sun to observe, but will reappear in early December in its closest approach to the earth.

Handbag-sized rock found on floor is actually worth £2.9 MILLION after experts say it's biggest chunk of Mars ever found

THE largest chunk of Mars ever found on Earth could sell for up to £2.9million ($4million) in a Sotheby's auction later this month. Believed to have crashed here as a meteorite, the Martian rock weighs in at 24.67 kilograms (54.39 pounds). 4 That's about 70 per cent larger than the previous record-holder - the 14.51kg Taoudenni 002 meteorite found in Mali back in 2021. Of the more than 77,000 officially recognised meteorites on Earth, fewer than 400 originate from Mars. That makes the rock a particularly rare find. Officially named NWA-16788, the specimen was discovered by a meteorite hunter in November 2023. Somewhere in the sparsely populated Agadez region of Niger, an area better known for its dinosaur fossils than its meteorites, the unnamed explorer found the lump of rock. The Shanghai Astronomy Museum has confirmed the rock's Martian identity based on a small sample sent there. The meteorite "shows minimal terrestrial weathering, indicating that its physical and chemical makeup have not been significantly altered since its arrival in the Sahara Desert," Sotheby's said in its listing. "In other words, NWA-16788 is likely a relative newcomer here on Earth, having fallen from outer space rather recently." Meteorites - a space rock that fails to burn up on entry through Earth's atmosphere - frequently fall to Earth. Although must are small and land unnoticed, often in the oceans. Mars Rock Samples- The Stories They Could Tell Scientists at Nasa It's thought the rock started its journey to our blue dot when an asteroid crashed into Mars and sent debris flying into space. However, some scientists question whether such a rare specimen should be up for sale. "It would be a shame if it disappeared into the vault of an oligarch," paleontologist Steve Brusatte from the University of Edinburgh told Jack Guy at CNN. "It belongs in a museum, where it can be studied, and where it can be enjoyed by children and families and the public at large." Planetary scientist Julia Cartwright, from the University of Leicester told CNN she hoped that the rock may still be used for science anyway. "The scientific interest will remain," she said. "The new owner may be very interested in learning from it, so we may still gather lots of science from this." Prior to landing at Sotheby's, the meteorite was show off to the public at an exhibition at the Italian Space Agency in Rome in 2024, and in a private gallery in Arezzo, Tuscany. The Sotheby's auction will begin on 16 July at 14:00 UTC. 4 4 Mars facts Here's what you need to know about the red planet... Mars is the fourth planet from the Sun It is named after the Roman god of war The landmass of Mars is very similar to Earth but due to the difference in gravity you could jump three times higher there than you can here Mars is mountainous and hosts the tallest mountain known in the Solar System called Olympus Mons, which is three times higher than Everest Mars is considered to be the second most habitable planet after Earth It takes the planet 687 Earth days to orbit the Sun The planet has a diameter of 4,212 miles, and has an average distance from Earth of 140 million miles Martian temperatures can vary wildly, reaching as high as 70F/20C or as low as -225F/-153C
