Scientists expand search for signs of intelligent alien life
Scientists have expanded the search for technologically advanced extraterrestrial civilizations by monitoring a star-dense region toward the core of our galaxy for a type of signal that could be produced by potential intelligent aliens that until now has been ignored.
Efforts to detect alien technological signatures previously have focused on a narrowband radio signal type concentrated in a limited frequency range or on single unusual transmissions.
The new initiative, scientists said this week, focuses on a different signal type that perhaps could enable advanced civilizations to communicate across the vast distances of interstellar space, Reuters reported.
These wideband pulsating signals for which the scientists are monitoring feature repetitive patterns - a series of pulses repeating every 11 to 100 seconds and spread across a few kilohertz, similar to pulses used in radar transmission. The search involves a frequency range covering a bit less than a tenth the width of an average FM radio station.
"The signals searched in our work would belong to the category of deliberate 'we are here' type beacons from alien worlds," said Akshay Suresh, a Cornell University graduate student in astronomy and lead author of a scientific paper published in the Astronomical Journal describing the new effort.
"Aliens may possibly use such beacons for galaxy-wide communications, for which the core of the Milky Way is ideally placed. One may imagine aliens using such transmissions at the speed of light to communicate key events, such as preparations for interstellar migration before the explosive death of a massive star," Suresh added.
The effort, called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS), is a collaboration between Cornell, the SETI Institute research organization and Breakthrough Listen, a $100 million initiative to search for advanced extraterrestrial life.
Using a ground-based radio telescope in West Virginia, BLIPSS has focused upon a sliver of the sky less than one-200th of the area covered by the moon, stretching toward the center of the Milky Way roughly 27,000 light years away. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).
This area contains about 8 million stars, Suresh said. If extraterrestrial life forms exist, they presumably would populate rocky planets orbiting in what is called the habitable zone, or Goldilocks zone, around a star - not too hot and not too cold.
The scientists in the various monitoring efforts passively scan for signals of alien beings and do not actively send their own signals advertising our presence on Earth.
No aliens yet have been detected in the monitoring efforts.

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