One of the spooky faces in this Halloween brainteaser is not like the others.

An unknown source has been sending radio blasts towards Earth since at least 1988, scientists say. The researchers do not know what object is sending the radio waves towards Earth. The nature of the waves is such that they do not conform with any models that attempt to explain it. For 35 years, the source has been sending out regular 20-minute blasts of energy that vary considerably in their brightness, researchers say. The emissions appear something like the blasts that come out of pulsars or fast radio bursts, which last for milliseconds to several seconds. But the newly discovered source sends radio signals that pulsate on a period of 21 minutes – something previously thought impossible by expected explanations. Pulsars are neutron stars that spin around quickly, throwing out radio blasts as they do. When one crosses Earth, the emissions can be picked up very briefly and brightly, like being in the path of the light from a rotating lighthouse. Scientists believe that process can only work if the magnetic field of the pulsar is strong, and it is rotating quickly enough – if not, there would not be enough energy to see the pulsar from Earth. That has led to the development of the “pulsar death line”, which suggests that sources must be spinning fast and strong enough to be detected. The newly discovered object named GPMJ1839-10, however, is way beyond that death line. If it is a pulsar, then it seems to be operating in ways that scientists thought impossible. It could also be a highly magnetised white dwarf or magnetar, an extra kind of neutron star with incredibly strong magnetic fields. But they do not tend to send out emissions of this kind, researchers believe. The signals have been detected on Earth since at least 1988, scientists found by going through old records, but they had gone unnoticed by those collecting that data. After the source was detected, researchers checked radio archives and found that the source has been repeating for at least 35 years. Yet more discoveries may be made in this way in the future, said Victoria M Kaspi, a professor of physics at McGill University who did not work on the study. “Only time will tell what else lurks in these data, and what observations across many astronomical timescales will reveal,” she wrote in an accompanying article. That might include some explanation of how unusual the newly discovered source is. By examining whether there are is a similar collection of other objects in the data, researchers might be able to understand the mechanisms behind the newly discovered emissions. The findings are reported in a new paper, ‘A long-period radio transient active for three decades’, published in the journal Nature.

Taylor Swift is playing her last US shows on her Eras Tour in LA this month and as you can imagine there is an unprecedented demand for tickets. For those who missed out during the chaotic Ticketmaster US ticket sales back in January, fans remain determined to hear the popstar's biggest hits and are attempting to bag last-minute tickets for the sold-out shows at SoFi Stadium in Inglewood. Originally, face-value tickets sold for $49 to $449, but according to the LA Times, tickets for the first show were on sale from $800 to a whopping $11,000 each on StubHub. Sign up to our free Indy100 weekly newsletter As the first show is due to take place tomorrow (August 3), tickets are continuing to rocket in price with the most expensive listing currently being priced at $25,677 for floor seats while a Level 1 suite is $102,070. Swifties have since been taking to social media to share their tips on how to secure face-value tickets on Ticketmaster which occasionally releases tickets last minute. @joecurtains how to get eras tour tickets day of for face value on ticketmaster: aka what I did to score floor seats only 2 hours before the show started. hoping this finds the right audience so fans can get in and beat the scalpers #taylorswift #erastour #swifttok #taylorsversion #tserastour #tickets #ticketmaster #erastourphilly #guide #howto #fyp #fypシ @Taylor Swift So who's in charge of the ticket prices? Well, there are a number of different factors at play. Promotors are the ones who officially set the prices and get money from ticket sales, but given it's Taylor Swift we're talking about she would also have a hand in choosing the venues and informing the promotor where to set prices. Venues charge a facility fee for hosting the concert and are paid by the promoters for this role, some venues have exclusive deals with certain promoters while others do not. And then there are the ticket companies like Ticketmaster who sell tickets with dynamic pricing where the price of a ticket changes according to demand - a move that has received criticism (though artists can opt out of this, as Swift did). On top of this, there is also the service fee for buying the ticket online, a processing fee that "covers miscellaneous expenses associated with online ticketing", and a facility charge for the venue to host the shows. According to Ticketmaster, input is given by the artist on the service fee and facility charge. Finally, there are the resellers who purchase tickets with no intention to attend the show but rather buy tickets to turn a profit by making listings on marketplaces like StubHub and SeatGeek. Prices can shoot up as there are no limits as to what the seller can charge. “This is a truly market-driven platform,” StubHub spokesperson Jessica Finn told LA Times. “So this is really about what sellers think that the price, the value of the ticket is, and what buyers think the value of the ticket is, and they effectively agree on it with a purchase... It’s very much a dynamic marketplace, prices go up and down and we don’t meddle with that.” A team of people or software bots can be used by the reseller to nab batches of tickets - hence why Swift decided for her UK tour to do album order presales, get fans to sign up for the general sale, and have staggered ticket sales throughout the day to try and stop bots and resellers.
