Fast radio bursts FRBs are one of the most puzzling mysteries of the space age. These one-off, millisecond-long signals pour in from all corners of the cosmos, and so far nobody's been able to figure out what causes them or where they're even coming from. Now, a team of astronomers has finally managed to trace one of the signals back to its home galaxy billions of light-years away, meaning we're closing in on the culprit.
FRBs were first discovered in , and since then 85 of them have been detected.

These short, sharp bursts are easy to spot in data but hard to pin down, thanks to their transient nature. With no clear idea of where they're coming from, astronomers have had a tough time trying to figure what could be causing them. And while the majority are one-hit wonders, some repeat at irregular intervals , which only complicates things further.
But now, astronomers are reporting that they've finally managed to pinpoint where one of these signals has come from, with incredible precision. Normally the signal has come and gone long before astronomers can react, so the Australian science agency CSIRO developed new technology that can react in under a second when a telescope picks up a burst. This freezes and saves the telescope data as it was when the signal rolled in, which tells scientists where to point other instruments to investigate its origin.
Using the new method, the team managed to home in on where it came from — a Milky Way-sized galaxy called DES J And not just the galaxy itself, either.
The team could pinpoint precisely where in the galaxy it originated. That's because ASKAP is made up of an array of radio telescopes, and the team can measure when the signal washes over each unit, then use those time differences to triangulate the location. With that cosmic pin dropped, the team then imaged the galaxy in closer detail to find out more about the environment there and look for clues as to what might be making the signals.

And all of this hullabaloo doesn't mean the iPhone is over or that Ive's legacy is sealed. After all, each of these services are so tied to the device that Oprah Winfrey, while on stage announcing her own offerings for Apple TV Plus, reminded viewers that the iPhone is " in billions of pockets, y'all.

While Apple's push into services will be a high-profile bet for the company in the coming years, it's not the only one. The device, which is designed to straddle augmented reality and virtual reality and is powered by Apple's own chips, is slated for Where that all leaves Apple and Ive with his new one-foot-in-one-foot-out job is unclear. One thing for sure is that analysts and Apple watchers alike are treating Ive like a soon-to-be-former employee. Ive is out.
Wedbush analyst Daniel Ives agreed. The major question now going forward is around future product innovation with one of the key visionaries of the Apple brand gone.
