The supermassive black hole at the centre of the Milky Way has been observed emitting continuous flares, as revealed by recent astronomical observations. The activity, detected using the James Webb Space Telescope (JWST), has been noted to occur across various timescales, with both short-lived and prolonged bursts being recorded. The findings contribute to the ongoing study of black holes and their interactions with surrounding matter, highlighting a level of variability that had not been fully understood before.

Flares Detected Across Multiple Observations

According to a study published in The Astrophysical Journal Letters, the JWST’s Near-Infrared Camera (NIRCam) was utilised to examine Sgr A* over multiple eight-to-ten-hour sessions, accumulating a total of two days’ worth of data over the past year. Researchers noted that flares occurred with varying intensity, with some lasting mere seconds, while others persisted for extended periods. The accretion disk surrounding the black hole was seen generating significant bursts up to six times per day, accompanied by smaller sub-flares.

As per reports, the flares are an expected phenomenon in supermassive black holes, though the unpredictable nature of Sgr A*’s activity sets it apart.

Potential Causes Behind Flare Activity

The mechanisms responsible for the flaring remain under investigation, with researchers considering multiple possible explanations. The study suggests that shorter, faint flares could be caused by minor disruptions within the accretion disk, akin to small ripples on a river’s surface. In contrast, brighter and more extended flares are believed to result from more substantial disturbances, possibly involving magnetic reconnection events, where charged particles accelerate to near-light speeds and release intense radiation bursts.

The phenomenon was compared to solar flares, explaining that while the sun’s surface experiences magnetic activity, the processes occurring near black holes are significantly more extreme. The NIRCam’s ability to observe two different infrared wavelengths allowed for further insights into the behaviour of these flares, with researchers noting a slight delay in the brightness of longer-wavelength emissions compared to shorter-wavelength events.

Future Observations Planned

A proposal has been submitted to conduct a continuous 24-hour observation of Sgr A* using the JWST to gain deeper insights into the flare activity. Researchers believe this extended observation period could reduce interference from background noise, allowing for a clearer analysis of potential patterns in the emissions.

SpaceX Falcon 9 Rocket Debris Falls Over Europe, Crashes in Poland

A bright fireball streaked across the European sky on February 19, as debris from a SpaceX Falcon 9 rocket made an uncontrolled reentry. Reports from the United Kingdom, Germany, and Poland confirmed sightings of the object as it burned up in the atmosphere before fragments crashed to the ground. Social media users in Lincolnshire, England, and Berlin, Germany, captured images and videos of the event, showing a blazing trail in the night sky. In Poland, a large metallic object was discovered outside the city of Poznań, prompting an investigation by local authorities and space agencies.

Rocket Debris Identified

According to the Polish Space Agency (POLSA), the object was part of the upper stage of the Falcon 9 rocket that launched from Vandenberg Space Force Base in California on February 1, 2025. The agency confirmed that the debris, weighing approximately four tons, originated from the Starlink Group 11-4 mission. The upper stage, which is designed to deorbit after completing its mission, failed to execute the manoeuvre as planned. Astrophysicist and satellite tracker Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics stated via X that the reentry occurred over the Irish Sea at 03:43 UTC, with debris reaching Poland and Ukraine within minutes.

Authorities Respond to the Incident

As per space.com, the Poznań Police reported receiving a call around 9:20 a.m. from workers at a company in Komornik, who discovered an unidentified cylindrical object on their premises. No injuries or property damage were reported. Another similar object was later found in a nearby forest near Wiry Village, approximately 30 kilometres away from the initial discovery. Agnieszka Gapys, press officer for POLSA, stated to Reuters that examinations were underway to confirm the origin of the debris. A third object was reportedly spotted, but official confirmation is still pending. As of Wednesday afternoon, SpaceX had not released a statement on the incident.

AI-Powered Evo-2 Model Generates DNA, Advances Genome Research

Breakthrough in AI-Driven Genome Design

A new artificial intelligence model has been introduced, marking a significant advancement in biological research. Developed using a dataset of 128,000 genomes covering various life forms, this AI can generate entire chromosomes and small genomes from scratch. Researchers claim it has the potential to interpret non-coding gene variants associated with diseases, making it a powerful tool in genetic research. This development is expected to enhance genome engineering by facilitating a deeper understanding of DNA sequences and their functions.

About the AI model

According to a study published by the Arc Institute, the AI model, named Evo-2, has been developed in collaboration with Stanford University and NVIDIA. The model, which has been made available through web interfaces, provides researchers with the ability to generate and analyse DNA sequences. Patrick Hsu, bioengineer at the Arc Institute and the University of California, Berkeley, stated during a press briefing that Evo-2 is intended to serve as a platform that scientists can modify to suit their research needs.

Trained on a Vast Repository of Genomes

Unlike previous AI models that focused primarily on protein sequences, Evo-2 has been trained on genome data, encompassing both coding and non-coding sequences. This extensive training set includes genomes from humans, animals, plants, bacteria, and archaea, covering 9.3 trillion DNA letters. The complexity of eukaryotic genomes, which contain interspersed coding and non-coding regions, has been incorporated into Evo-2’s framework to enhance its ability to predict gene activity.

Performance Evaluation and Capabilities

Anshul Kundaje, computational genomicist at Stanford University, stated to Nature that independent testing would be required to fully assess Evo-2’s capabilities. Preliminary results suggest that it performs at a high level when predicting the effects of mutations in genes such as BRCA1, which is linked to breast cancer. The model was also used to analyse the genome of the woolly mammoth, further demonstrating its ability to interpret complex genetic structures.

Generating New DNA Sequences

The AI has been tested in designing new DNA sequences, including CRISPR gene editors, as well as bacterial and viral genomes. Earlier versions of the model produced incomplete genomes, but Evo-2 has shown improvements by generating more biologically plausible sequences. Brian Hie, computational biologist at Stanford University and Arc Institute, mentioned that while progress has been made, further refinements are necessary before these sequences can be fully functional in living cells.

Potential Applications in Genetic Research

Researchers anticipate that Evo-2 will aid in designing regulatory DNA sequences that control gene expression. Experiments are already underway to test its predictions on chromatin accessibility, which influences cell identity in multicellular organisms. Yunha Wang, computational biologist and CEO of Tatta Bio, suggested that Evo-2’s ability to learn from bacterial and archaeal genomes could assist in designing novel human proteins.

Future Prospects for AI in Genome Design

Scientists involved in the project aim to push beyond protein design towards comprehensive genome engineering. With ongoing refinements and laboratory validations, Evo-2 may contribute to advancements in synthetic biology and precision medicine. The model’s role in understanding genetic regulation and designing functional DNA sequences is expected to grow as more researchers adopt and refine its capabilities.
