Astronomers found a heartbeat-like radio signal coming from a galaxy

Published

From over a billion light-years away and surrounded by a plasma cloud, a new radio wave is being pick up on Earth, courthouse news agency reported.

In a new study published in Nature, astronomers discovered a new radio signal strikingly different from other recorded radio bursts. Captured by the Canadian CHIME Experiment, a massive telescope that turns digital signals into three-dimensional hydrogen density maps, the novel radio wave is labeled FRB 20191221A.

Fast radio bursts, or FRBs, were first detected in 2007 and are a pulse of radio wave activity that usually only last a couple of milliseconds. The CHIME telescope has witnessed over a thousand radio burst sources since 2018. Though there is more study to be done on the burst origins and processes, it is estimated that approximately a thousand fast radio bursts arrive in Earth’s sky every day, read the report.

“There are not many things in the universe that emit strictly periodic signals. Examples that we know of in our own galaxy are radio pulsars and magnetars, which rotate and produce a beamed emission similar to a lighthouse. And we think this new signal could be a magnetar or pulsar on steroids,” says Daniele Michilli, a postdoc at Massachusetts Institute of Technology’s Kavli Institute for Astrophysics and Space Research, in a press release.

According to the report with most signals coming and going like a flash, the new radio burst is a game-changer, as it puts out a persistent burst every few seconds.

“It was unusual. Not only was it very long, lasting about three seconds, but there were periodic peaks that were remarkably precise, emitting every fraction of a second — boom, boom, boom — like a heartbeat. This is the first time the signal itself is periodic,” Michilli added.

The burst is coming from a far-off galaxy, over a billion light-years away from Earth, and its source is thought to be over a million times brighter than neutron stars in our own Milky Way. Additionally, the burst source may usually be less bright, causing a train of radio waves to emit while it rotates, courthouse news reported.

Comparing the properties of FRB 20191221A to other signals caught by the CHIME telescope, it seems that a very turbulent plasma cloud surrounds the source.

“This detection raises the question of what could cause this extreme signal that we’ve never seen before, and how can we use this signal to study the universe. Future telescopes promise to discover thousands of FRBs a month, and at that point, we may find many more of these periodic signals,” Michilli noted.

Russia fines Google more than the world’s total GDP over YouTube bans

Published

on

Russia has fined Google $2.5 decillion after the US tech giant took action against pro-Kremlin TV channels on YouTube following Moscow’s invasion of Ukraine.

Russia imposed a daily fine four years ago - a fine that has since swelled to an unprecedented level - ($20,000,000,000,000,000,000,000,000,000,000,000 - a 33-digit figure).

To put this into perspective, global GDP reaches an estimated $110 thousand billion (12-digit figure), according to the IMF.

Speaking to Russia’s TASS news agency, one expert, Roman Yankovsky from the HSE Institute of Education, said Google “clearly will not pay this penalty, and the Russian Federation will not be able to recover this money from the company."

Euronews reported that a short calculation shows that he is right.

Google's holding company, Alphabet, has a market capitalisation of slightly more than $2 trillion. Even with earnings of $80.54 billion from the last quarter, the tech giant doesn’t seem to be able to afford to pay the fine.

Google first barred pro-Moscow channel Tsargrad TV, which is owned by oligarch Konstantin Malofeev, four years ago.

At the time, Google was fined a daily penalty of 100,000 roubles and warned that amount would double every 24 hours if it went unpaid.

The original fine has been compounded by further penalties after Google eventually blocked a total of 17 Russian TV channels as a result of international sanctions, The Telegraph reported.

The tech giant now owes a staggering $2.5 decillion.

Apple launches new iPad mini with AI features

Apple said it would roll out the first set of AI features in the U.S. version of the English language this month through a software update with iPadOS 18.1.

Apple on Tuesday launched its new generation of the iPad mini packed with AI features including writing tools and an improved Siri assistant, as the iPhone maker races to boost its devices with artificial-intelligence capabilities, Reuters reported.

The new iPad mini is powered by Apple's A17 Pro chip, which is used in the iPhone 15 Pro and Pro Max models. With a six-core central processing unit, the A17 Pro would boost CPU performance by 30% compared to the current generation iPad minis and is central to running Apple Intelligence, Apple's AI software.

Apple said it would roll out the first set of AI features in the U.S. version of the English language this month through a software update with iPadOS 18.1.

The features will be available for iPads with A17 Pro or M1 chips and later generations, Apple said, adding it will roll out additional features including image-generation tools, Genmoji and ChatGPT-powered capabilities over the next several months, read the report.

Apple in September unveiled its long-awaited, AI-boosted iPhone 16 lineup, but with the AI features still in test mode, the company failed to excite some investors while early sales data raised some questions around demand.

Still, research firm Canalys on Monday said the iPhone 16 would help Apple's sales in the fourth quarter and drive momentum into the first half of 2025, after Apple reached a record high third-quarter shipments.

The iPad mini, starting at $499, is available for pre-orders starting on Tuesday and will begin arriving to customers and Apple store locations next week, Apple said.

Iran sends satellites to Russia for rocket launch

In September, Iran carried out its second satellite launch this year using a rocket built by its Revolutionary Guards

Published

Iran has sent two locally made satellites to Russia to be put into orbit by a Russian space vehicle, the semi-official news agency Tasnim reported on Saturday, in the latest space cooperation between the two U.S.-sanctioned countries.

The development of Kowsar, a high-resolution imaging satellite, and Hodhod, a small communications satellite, is the first substantial effort by Iran's private space sector, the report said.

Russia sent Iranian satellites into orbit in February and in 2022, when U.S. officials voiced concern over space cooperation between Russia and Iran, fearing the satellite will not only help Russia in Ukraine but also help Iran monitor potential military targets in Israel and the wider Middle East, Reuters reported.

Kowsar could be used in agriculture, natural resource management, environmental monitoring, and disaster management, Tasnim said.

Hodhod is designed for satellite-based communications and could be used in remote areas with little access to terrestrial networks.

In September, Iran carried out its second satellite launch, this year using a rocket built by its Revolutionary Guards. 

The launch came as the United States and European countries accuse Tehran of transferring ballistic missiles to Russia that could be used in its war with Ukraine. Iran has denied this.
