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

Afghanistan launches first 5G trial in Kabul to boost telecom services
According to ministry spokesperson Enayatullah Alokozai, AWCC has upgraded 74 telecom antennas in Kabul to 5G on a trial basis.
Afghanistan has launched its first-ever 5G telecommunications trial in Kabul, marking a major milestone in efforts to modernise the country’s digital infrastructure.
The announcement followed a meeting between Hamdullah Nomani, Minister of Communications and Information Technology, and Aliullah Sarwari, head of the Afghan Wireless Communication Company (AWCC), where discussions focused on expanding telecom coverage, improving service quality, and extending connectivity to remote regions.
According to ministry spokesperson Enayatullah Alokozai, AWCC has upgraded 74 telecom antennas in Kabul to 5G on a trial basis. Once technical preparations and testing are completed, the company plans to extend 5G services to other provinces.
Officials also reported steady progress on broader infrastructure development. Eight telecom sites approved during previous official visits to northern and southeastern provinces have been completed, one is nearing completion, and construction continues on two additional sites expected to become operational soon.
In parallel, the Afghanistan Telecom Regulatory Authority (ATRA) has approved eight more telecom sites under the Telecom Development Fund (TDF), with implementation scheduled in the coming months.
Sarwari noted that since the beginning of 2026, AWCC has built and activated 46 telecom sites using its development budget, while work continues on a further 186 sites nationwide.
He also thanked the Ministry of Communications and Information Technology for its ongoing support in facilitating sector growth and improving service delivery.
Nomani meanwhile emphasised that telecommunications play a crucial role in national development and said the government remains committed to working closely with operators to expand modern, high-quality digital services.
Officials added that cooperation between the ministry, regulators, and telecom companies will continue across all operational and regulatory areas to strengthen Afghanistan’s communications network.

NASA set for first crewed moon return in over half a century
NASA is preparing to launch the first crew of astronauts toward the moon in over 53 years with its second Artemis mission, a key test flight in humanity’s broader lunar goals as the U.S. races to reassert leadership in space faced with growing competition from China.
Three U.S. and one Canadian astronaut are due for liftoff aboard NASA’s Orion capsule and Space Launch System rocket on Wednesday for a 10-day test mission swinging around the moon and back, a winding journey taking them deeper into space than humans have ever gone before, Reuters reported.
The mission is the first crewed test flight in NASA’s Artemis program, the flagship U.S. effort to begin regular flights to the moon, at an estimated cost of at least $93 billion since 2012. Not since Apollo 17 in 1972 have humans touched down on the moon’s surface, a tricky feat NASA aims to repeat in 2028 at the rugged lunar south pole.
The U.S. is the only country to have put humans on another celestial body with its six lunar landings of the Apollo program, driven by competition with the former Soviet Union.
China, a formidable technological rival to the U.S., has made steady progress in its own moon program in recent years, with a string of robotic lunar landings and a 2030 goal to put its own crew on the surface. U.S. officials have focused on beating China to the surface.
ANSWERING ‘THE QUESTION OF OUR LIFETIME’
NASA astronaut Christina Koch, Artemis II mission specialist, on Sunday said the moon is a “witness plate” to the solar system’s formation, and a stepping stone to Mars, “where we might have the most likelihood of finding evidence of past life.”
“Many, many countries have recognized the value that there is in exploring further into the solar system, to the moon and on to Mars,” she told reporters. “They recognize that not only can we gain all these extremely tangible benefits, but that we have the opportunity to answer the question that could be the question of our lifetime, which is, are we alone?”
“Answering that question starts at the moon,” she said. “The question is not should we go, but should we lead, or should we follow?”
Through a series of increasingly advanced Artemis missions extending into the next decade, the U.S. aims to set precedent for how others will operate and coexist on the moon’s surface, where someday countries and companies can exploit rocky lunar resources and practice for much more difficult missions to Mars.
COMMERCIAL LUNAR MARKET
NASA is relying on an array of companies in its moon program with the hope of stimulating a commercial lunar market in the future, the value of which is hard to estimate, analysts say.
A PricewaterhouseCoopers report from January estimates $127 billion in revenues by 2050 from lunar surface activities, with investments potentially reaching $72 billion to $88 billion through the same period.
But for now, and in the near future, governments will drive companies’ lunar strategies and revenue. It will be a long time before commercial growth exists on the moon independently of government funding, said Akhil Rao, an economist at analysis firm Rational Futures who was a research economist at NASA.
“NASA did not see a short-run economic value that companies would be able to derive that would allow NASA to be hands-off,” said Rao, who was among a team of economists and space policy staff laid off last year amid the Trump administration’s sweeping federal workforce cuts.
The Artemis II mission will pose a greater test of NASA’s Orion capsule and SLS, which conducted a similar mission without crew in 2022. The astronauts on board will test critical life-support systems, crew interfaces, navigation and communications before NASA proceeds with more complex missions in the following years.
Liftoff is scheduled for April 1, though it could happen any day after until April 6, depending on weather conditions in Florida and any last-minute snags with the rocket. Thereafter, another launch window, determined largely by the orbital mechanics between Earth and the moon, opens on April 30.
Artemis III, the next mission planned for 2027, will involve the Orion capsule docking in Earth’s orbit with NASA’s two lunar landers – the Blue Moon system from Jeff Bezos’ Blue Origin and Starship from Elon Musk’s SpaceX. The delicate tag-up will demonstrate how the landers will pick up astronauts before heading for the moon’s surface.
That mission was added to the program in February by NASA’s new administrator, Jared Isaacman, a billionaire private astronaut who has more broadly shaken up the program with new objectives. His decision pushed the program’s first crewed lunar landing to Artemis IV.
The architecture is more complex than the Apollo missions, involving an array of companies funded by NASA with the hope of stimulating private competition and market activity around the moon. Boeing and Northrop Grumman lead SLS and Lockheed Martin builds Orion for NASA.
SpaceX and Blue Origin are developing their own landers with NASA funding but under different types of contracts that allow them to offer the spacecraft to other customers.

Trump administration set to receive $10 billion fee for brokering TikTok deal, WSJ reports
Vice President JD Vance had in September said that the new U.S. company will be valued at around $14 billion.
President Donald Trump’s administration is set to receive a roughly $10 billion fee from investors in the recently completed deal to take control of TikTok’s U.S. business, the Wall Street Journal reported on Friday, citing people familiar with the matter.
TikTok’s Chinese owner, ByteDance, in January finalized a deal to establish a majority American-owned joint venture that will secure U.S. data, to avoid a U.S. ban on the short video app used by over 200 million Americans.
TikTok USDS Joint Venture LLC will secure U.S. user data, apps and algorithms through data privacy and cybersecurity measures. It disclosed few details about the divestiture.
Vice President JD Vance had in September said that the new U.S. company will be valued at around $14 billion.
The payment is part of the agreement through which investors friendly with the administration gained control of TikTok’s U.S. operations from ByteDance, WSJ said. It is on top of the investments already made to establish a new entity to operate the app in the U.S.
Investors Oracle (ORCL.N), Silver Lake, Abu Dhabi’s MGX and other backers paid about $2.5 billion to the Treasury Department when the deal closed and are to make a number of subsequent payments until the total reaches $10 billion, per the Journal.
TikTok and the White House did not immediately respond to Reuters requests for comment.
Officials from the administration have said the fee is justified, citing Trump’s role in rescuing TikTok’s U.S. operations and guiding negotiations with China to complete the deal while tackling lawmakers’ concerns over national security, according to WSJ.
Earlier this month, Trump and U.S. Attorney General Pam Bondi were sued by retail investors in two social media rivals of TikTok seeking to reverse the U.S. president’s approval of a deal by the company’s Chinese owner ByteDance to form a majority American-owned joint venture.
