What simply occurred? A world crew of researchers have found a cosmic anomaly in contrast to something beforehand witnessed. The article in query, positioned roughly 15,000 light-years away in our very personal Milky Manner galaxy, has been noticed emitting each radio waves and X-ray radiation.
The celestial physique, dubbed ASKAP J1832- 0911, was initially discovered by astronomers utilizing the Australian Sq. Kilometer Array Pathfinder (ASKAP), a radio telescope positioned in Australia. One other look utilizing NASA’s Chandra X-Ray telescope discovered the thing additionally emitted X-rays in an uncommon but predictable sample.
Each 44 minutes, the thing flashes each radio waves and X-rays for 2 minutes straight.
Staff chief Zieng (Andy) Wang stated the thing is in contrast to something they’ve seen earlier than, though its origins are possible not as mysterious as one would possibly initially assume.
Wang stated the thing might very nicely be what’s left of a useless star with highly effective magnetic fields, referred to as a magnetar – or maybe one thing so simple as a pair of stars in a binary system during which one of many two is a extremely magnetized white dwarf.
Then once more, neither clarification totally explains precisely what astronomers are witnessing with its conduct so the jury continues to be out. Conversely, Wang added, the invention might be a brand new kind of physics or a contemporary mannequin of stellar evolution we’ve not seen earlier than.
NASA’s Chandra X-ray observatory launched into area approach again in 1999 and has been orbiting Earth ever since. The ASKAP radio telescope array has been operational since 2012, and consists of 36 large antennas – every measuring 39 ft in diameter – that work collectively as one instrument.
Additional research shall be wanted to assist astronomers higher perceive precisely what they’re . At 15,000 light-years away, the thing is considerably close by within the grand scheme of the universe however nonetheless fairly far-off in precise distance. For reference, one light-year is roughly equal to 6 trillion miles.
The crew’s analysis has been published within the journal Nature and is titled, “Detection of X-ray Emission from a Shiny Lengthy-Interval Radio Transient.”
