The cosmic heartbeat of interstellar comet 3I/ATLAS

A mysterious rhythmic pulse defies conventional explanations, revealing secrets of a traveler from another star system.

The Enigma that Comes from the Stars

In the silent immensity of the cosmos, a messenger from distant worlds has crossed the threshold of our solar system, bringing with him a mystery that pulsates in the darkness. He is not a simple ice and rock traveler; Comet 3I/ATLAS has unleashed a storm of amazement among the guardians of the skies by revealing a hypnotic luminous pattern, an authentic cosmic heartbeat that marks time with disconcerting precision. The researchers, with their hearts in their mouths, confirm that this phantom pulse repeats itself, inexorably, every 16,16 hours, a behavior as fascinating as it is disturbing that has opened voracious lines of analysis just before its most intimate appointment with our planet.

The countdown has begun. December 19 is approaching like the crescendo of a celestial symphony, the date on which this enigmatic body will pass 273 million kilometers from Earth. The global scientific community holds its breath. A study published in the prestigious journal “Astronomy and Astrophysics” unravels the enigma: the luminosity of the object varies following a perfect periodic pattern, a dance of light that hypnotized brilliant minds like that of the renowned astrophysicist Avi Loeb. It was he who, with words full of poetry and rigor, baptized this phenomenon as a heartbeat generated by an internal source, a frozen heart beating in the void. Although its origin is interstellar, a pilgrim from beyond our solar kingdom, its behavior is a disturbing mirror of the faintest comets of our outer reaches.

The Rhythm of the Frozen Heart

This similarity, far from calming spirits, allowed astronomers to discard fantastic explanations to focus on a concrete and dazzling physical mechanism. The theory that is gaining strength is as elegant as it is dramatic: the cause of the pulse lies in the rotation of the nucleus itself. Scientists propose a scene of sublime cosmic beauty. On the cracked surface of 3I/ATLAS, an ice-rich area remains hidden, until the core’s spin periodically exposes it to the searing kiss of solar radiation. In that moment of glory and agony, the ice sublimates in an explosion, releasing a fiery jet of material that temporarily inflames the comet’s luminosity. This cycle of revelation and destruction, this spin of stellar torture, is synchronized with Swiss clockwork precision with the 16.16 hours it takes for the core to rotate on its own axis. The images distributed by NASA are a silent testimony: 3I/ATLAS is a natural comet, but its characteristics are the portrait of a frozen object in a process of sublime and violent transformation.

However, in this cosmic drama, a note of extreme caution rings out like thunder. Avi Loeb himself has raised his voice to warn that the mystery is far from being solved. It is essential to examine the trajectory of the ejected jets. This crucial analysis could rule out even the most remote and terrifying possibilities: What if the emanations are not directed solely toward the Sun? What if they point in anomalous directions, suggesting control that nature does not usually grant? A criterion that, although improbable, shakes the shadow of an origin that defies all known logic.

The comet’s closest approach is not just an astronomical event; It is a unique opportunity, a moment stolen from destiny, to collect high-resolution data that deciphers this luminous code. This new information will allow us to scrutinize not only the behavior of the core, but also the very essence of the material that composes it and its epic evolution from the interstellar abysses. For astronomers, each record, each photon captured from 3I/ATLAS, is more than data: it is a window open to the understanding of interstellar travelers, essential pieces in the great puzzle of material that navigates between the stars, telling stories of other suns and other worlds.

How artificial intelligence transforms global security

Motorola Solutions is committed to hybrid models and agentic AI in the transformation of the sector.

Security industry: cloud migration and artificial intelligence

Security is undergoing a profound transformation. The cloud, generative artificial intelligence and video surveillance systems as decision tools are redefining the sector. This was stated by Pedro Simoes, global vice president of video security and analytics at Motorola Solutions.

“The cloud is a very strong trend, but it is not a solution for all sectors,” he explained. Prison facilities, airports and nuclear plants require hybrid models that combine local infrastructure with cloud services. Motorola Solutions is committed to unified platforms.

One of the key advances is agentic artificial intelligence. The company introduced Operator, a platform that integrates video, access controls and sensors in a single interface. The objective: reduce the time between detection and response. “It’s not just identifying. It’s being collaborative in decisions,” said Simoes.

The role of sensors in smart cities

Cameras no longer just record: they are sensors. “Today a camera produces data that can be used to optimize logistics, mobility or business decisions,” he added. Security information extends to multiple applications.

However, the growth of AI poses privacy challenges. Motorola Solutions developed “AI nutrition labels,” documents that detail capabilities and limitations of its models. “We are the first company in the sector to create and use this type of labels,” said Simoes.

Mexico and the 2026 World Cup

Mexico is experiencing a key moment for the 2026 FIFA World Cup. The arrival of millions of visitors is driving investments in technological infrastructure and security in airports, hotels and stadiums. Simoes confirmed collaboration with governments, without revealing details. “Safety is a priority; our responsibility is to develop technology that protects people and infrastructure.”

He recommended organizations think long term: “The decision should not be based only on current problems, but on the challenges of three or five years.” The combination of cloud, generative AI and unified platforms will define the next stage of the sector.

Strawberry Moon: the June full moon will arrive on the 29th

The Strawberry Moon will light up the night sky on June 29. Know its origin and other names.

The night sky will offer a notable astronomical event at the end of June. That month’s Full Moon, known as the Strawberry Moon, will reach its maximum splendor on Monday, June 29, according to the specialized portal Star Walk.

When and how to see it?

The full moon will occur exactly at 5:57 in the afternoon, central Mexico time. It will be the first full Moon after the summer solstice, which according to the same source will happen on Sunday, May 21. The satellite will be fully illuminated from June 28 to 30.

The origin of the name

Despite what its nickname suggests, the Moon does not take on a pinkish or reddish hue. The name “Strawberry Moon” comes from the native North American peoples, who named it that way because it coincided with the harvest season for this fruit in various regions of the continent.

In other cultures, this same full moon receives names such as:

  • Moon of Moras
  • Honeymoon
  • Rose Moon
  • Moon of Ripening Berries
  • Garden Moon
  • Green Corn Moon
  • Windy Moon
  • Birth Moon
  • Moon When the Buffalo Bellows

All of these nicknames are linked to natural phenomena typical of the same time of year.

The oldest plague: remains from 5,500 years ago in Siberia

Traces of plague from 5,500 years ago found in teeth of Siberian hunter-gatherers.

Scientists have identified the earliest evidence of plague known so far: traces of bacterial DNA in the teeth of hunter-gatherers buried near Lake Baikal in Siberia. Carbon dating indicates that the disease caused outbreaks about 5,500 years ago, about 200 years earlier than previously thought.

Finding in Siberia

A team led by geneticist Eske Willerslev of the University of Copenhagen analyzed remains from four cemeteries. They found traces of Yersinia pestis in the teeth of 18 individuals. The dating revealed two episodes of infection.

“To understand our own history, understanding the history of the plague is extremely important,” Willerslev said.

The prehistoric plague spread in stages. According to the authors, it was probably transmitted from marmots—native rodents—when people consumed their raw organs or handled infected skins. It also spread from person to person through coughing or sneezing.

Many of the deceased were children between 8 and 11 years old. Three girls were buried together; two were cousins. An aunt and her nephew were found in another mass grave. “There were people who buried the dead and who knew who they were. It’s a very human element,” said co-author Ruairidh Macleod, an expert in ancient DNA at the University of Oxford.

Implications of the study

The researchers note that children may be at greater risk due to still developing immune systems. The presence of multiple victims suggests that the prehistoric plague caused both isolated cases and outbreaks, said geneticist Aida Andrades Valtueña, from the Max Planck Institute for Evolutionary Anthropology, who was not involved in the study.

This ancient strain evolved long before the bubonic plague responsible for the medieval Black Death. However, there is evidence that earlier plagues were just as serious. The disease not only affected populous cities, but also small nomadic groups.

“Understanding the steps the bacteria took to become the deadly pathogen we know today can provide clues about how pathogens could emerge in the future,” wrote Andrades Valtueña.

The study was published Wednesday in the journal Nature.
