First spotted in 2007, FRBs are one of the most intriguing mysteries in astrophysics. They appear all over the sky, and astronomers aren’t sure what causes them. n early testing during July and August, before it began full operations, CHIME spotted 13 FRBs. Prior to this, astronomers had between 50 and 60 examples. The more FRBs that astronomers find, the greater the chance they can start to pin down their origin. CHIME also detected only the second known FRB that repeats, meaning that the radio flashes re-appear at the same point in the sky. It saw the repeater pop up...

A source of repeating radio waves seen from one point in the sky presents astronomers with numerous mysteries. The source of this signal, where radiation builds and ebbs over a period of 16 days, remains a question. The longevity of these cycles — now seen continuing for over 500 days — could either present another mystery, or perhaps a clue to what is going on at the center of these displays. Fast radio bursts (FRBs) are one form of highly-energetic explosion in deep space. Thought to be caused by small, massive objects, although the exact nature of these objects is...

Astronomers have never before seen fast radio bursts being emitted in such a regular pattern, and still don't know their origin. Astronomers have detected alien signals - that is, signals from a foreign galaxy - being emitted in an unusually regular 16-day cycle. Fast radio bursts (FRBs) are not in and of themselves unusual - the first was detected in 2007 - but previous observations have shown them to be mostly emitted at random. While there have been some bursts which repeated, as astronomers discovered previously, they have never been seen repeating in such a steady cycle. The origin of...

To pay tribute to its 175th anniversary, Patek Philippe created a collection of limited-edition commemorative timepieces, and one of them stands out in particular. It is the so far most complicated wristwatch of the eminent family-owned watchmaking company and decidedly one of the world's most elaborate wristwatches. This is due not only to the number of complications involved but also to the horological degrees of complexity, two of which have been added to the annals of watchmaking for the first time. Moreover, the Grandmaster Chime is the first double-face wristwatch presented by Patek Philippe that can be worn with either...
