MALANG POSCO MEDIA – Satellite astronomy China’s Einstein Probe (EP), sent into space in January this year, has made a number of preliminary findings, including an unusual mysterious transient phenomenon. This can help further understanding of the universe and extreme physical processes.
Inspired by the function of lobster eyes, EP uses new X-ray detection technology to observe transient phenomena in the universe that flash like fireworks, to reveal more about this intense and little-known side of the cosmos.

In the testing phase, the satellite’s performance exceeded its design expectations. The Chinese Academy of Sciences (CAS) announced the initial results on Thursday (31/10), including the discovery of various types of transient events.
The satellite has another name, namely “Tianguan,” to commemorate the observation and documentation of the famous supernova SN1054 by ancient Chinese people in 1054 AD. This scientific achievement during the Song Dynasty (960-1279) is an early example of China’s contribution to human understanding of nature. universe. The supernova was observed in the “Tianguan” region of the ancient Chinese constellation system, hence the name “Tianguan guest star”.
Ancient Chinese people used the term “guest stars” to refer to transient events, most of which were novae and supernovae that were bright enough to be visible with the naked eye at that time. The supernova remnant later evolved into the famous Crab Nebula.
During the initial testing and operation phase, the EP detected 60 confirmed transient events and many other candidate events, including stars, white dwarfs, neutron stars, black holes, supernovae, and gamma-ray bursts.
In the Milky Way, the satellite has discovered a number of new transient sources, one of which is a new X-ray binary system, possibly a stellar-mass black hole or neutron star, named EP240904a.
So far, the most distant transient source detected by the EP is a gamma-ray burst, codenamed EP240315a, which is 25.6 billion light years away.
These findings demonstrate the satellite’s ability to detect gamma-ray bursts from the distant early universe, providing a new perspective for further understanding the physical processes of stellar collapse that lead to the formation of black holes and relativistic jets, said researcher Yuan Weimin. lead in the EP mission and also a researcher at the National Astronomical Observatory of China which is overseen by CAS.
The research was led by the EP science team, which collaborated with a number of space facilities and Earth-based facilities and involved many international scientists from various countries and institutions.
On April 8, EP detected a transient event, codenamed EP240408a, and recorded a very intense X-ray flare from the event, whose brightness increased 300-fold and lasted only 12 seconds. The X-ray emissions from this source disappeared about 10 days later.
The unusual phenomenon, as well as other strange radiation features that accompany it, do not fit any type of transient event that has been known before, indicating that this finding may represent an unknown class of transient source, Yuan said.
The findings have been published in the latest issue of the Chinese academic journal, SCIENCE CHINA: Physics, Mechanics & Astronomy.
“The greatest significance of the EP’s initial results is the demonstration of the EP’s ability to capture and study short-lived cosmic events. “This will give us new insights into understanding the physical laws under extreme conditions that governed the processes in these intense cosmic events and the formation of the first stars and black holes,” said Yuan.
The EP mission is one of a series of space science missions led by CAS. This mission is also an international collaborative mission with contributions from the European Space Agency (ESA), the Max Planck Institute for Extraterrestrial Physics (MPE) in Germany, and the French space agency CNES.
“EP has opened a new window for observing the dynamic X-ray universe,” said Dr. Erik Kuulkers, EP project scientist from ESA.
EP has proven the importance of wide-field monitoring of the X-ray sky. EP satellite survey and follow-up capabilities have enabled the discovery of new X-ray transient phenomena and routine monitoring of known sources.
The EP’s findings show that the EP has had a major impact on science, said Paul O’Brien, head of the Astrophysics department at the Faculty of Physics and Astronomy at the University of Leicester. (ntr/jon)

The Cosmic Show: China’s Einstein Probe Unveils Stellar Secrets
By the Cosmic Comedians: A blend of Carr, Atkinson, Gervais, & Evans
Welcome to the galaxy’s latest news bulletin, where space just got a whole lot more exciting, and heck, if I had a star for every time something interesting happened in astronomy, we’d literally be in a whole new dimension! The Einstein Probe—or as I like to call it, “that smart satellite with a flair for drama”—has taken to the cosmic stage, and boy is it stealing the show!
This little marvel, launched by China in January, is already causing a ruckus with its early findings, including a mysterious phenomenon that will have astrophysicists scratching their heads like they’ve just tried to solve a Rubik’s Cube after a night out. We’re talking about those elusive transient events that pop up like a bad signal on your TV—exciting, unexpected, and often leaving you wondering what you just witnessed.
Lobster Eyes & Cosmic Fireworks
Now, here’s where it gets interesting! Inspired by lobster eyes—because clearly, that’s what we all think of when we look up at the stars—this satellite uses unique X-ray detection technology to capture fleeting cosmic moments. It’s like having a lobster at the controls, spotting fireworks in the universe that most of us would miss while checking our phones!
During its initialization, the EP, which has been informally dubbed “Tianguan”—to honor the ancient Chinese who noted supernovae back in 1054 AD (a time when TikTok was just a vague sound at the back of the cave)—captured a jaw-dropping 60 confirmed transient events. From black holes to gamma-ray bursts, the EP is like the universe’s very own social media influencer, drawing attention to stellar phenomena that we didn’t even know we needed to know about!
A Stellar Discovery: New Sources Unearthed
How exciting is it that among its celestial discoveries, the culprit “EP240904a” could very well be a stellar-mass black hole or a neutron star? That’s right, folks! It’s like the universe dropped a surprise party on us, and we’re just trying to keep up with the guest list.
Oh, but wait—there’s more! Their star attraction, a gamma-ray burst codenamed “EP240315a,” is 25.6 billion light-years away. That’s almost like finding out your Wi-Fi router can connect to the International Space Station. We knew the universe was big, but now we’re talking enormous!
A New Class of Cosmic Drama Unveiled
But the real kicker? On April 8, the EP detected a transient event that heightened its intensity by 300-fold. I mean, forget measuring in watts; at this rate, we should just call it the “cosmic espresso shot!” The event lasted just 12 seconds but left behind a lingering question: is this a new class of transient source? A cosmic enigma wrapped in an X-ray shell? Sounds like the plotline of a sci-fi movie!
Dr. Yuan Weimin, the head of this scientific circus, says these initial results could shed light on the extreme physical processes of the universe that lead to the birth of black holes and who knows what else. So, what’s next? A cosmic reality TV show? “Keeping Up with the Kardashians—In Space”? Only time will tell.
Global Collaboration: The Universe is Better Together
But wait, there’s more intergalactic teamwork! This mission isn’t just a solo gig. It has a line-up that includes the European Space Agency, Germany’s Max Planck Institute for Extraterrestrial Physics, and the French space agency CNES. It’s like the Avengers of astronomy, and they’re assembling to unravel the secrets that the universe holds.
Final Thoughts—A New Window to the Universe
The EP is proving that we can still discover new wonders even in this age of information overload. It has opened a new window for observing the dynamic X-ray universe and demonstrated a powerful tool for monitoring previously detected sources.
So, in conclusion, let’s give a round of applause to the Einstein Probe! It seems space is not just vast but filled with thrilling mysteries waiting to be solved. Just don’t ask me about dark matter; that will take cocktails and a very long night of sharing conspiracy theories!
