The Solar Orbiter spacecraft has obtained unprecedented footage of the solar wind. This flow of charged particles appeared as massive spiral structures, resembling a giant cyclone. Extending outwards to a distance of up to three solar radii, these formations persisted for over three hours.
These remarkable images were captured by the Metis coronagraph aboard Solar Orbiter. Metis specializes in detecting various types of radiation emitted by the solar corona, while effectively blocking direct sunlight from the star’s surface.
Visualizing the wind's structure represents a significant step forward in understanding its nature. Previously, measurements were confined to localized points reached by the particle flow. Now, scientists have observed a comprehensive, dynamic picture, witnessing how particles accelerate, escape the Sun’s gravity, and form turbulent patterns.
Solar wind continuously interacts with Earth, affecting not only phenomena like the Northern and Southern Lights (auroras), but also influencing satellite operations, communication systems, and navigation technologies. Although its intensity varies with solar activity, the exact formation mechanisms remain unclear.
These new insights from Solar Orbiter promise to enhance our comprehension of these processes. The mission is scheduled to continue until 2026, with a potential extension through 2030.

The James Webb Space Telescope has achieved a groundbreaking astronomical milestone, capturing clear images of auroras on Neptune—a sight astronomers are already hailing as historic.
Auroras occur when charged particles ejected by the Sun interact with a planet’s magnetic field, entering its upper atmosphere and creating a stunning luminous display.
Hints of auroral activity on Neptune were first spotted by Voyager 2 back in 1989, but concrete evidence remained elusive. Over the decades, clear visuals of auroras emerged for Jupiter, Saturn, and Uranus, leaving Neptune as the mysterious missing link—until now.
Thanks to James Webb’s exceptional sensitivity in the near-infrared range, astronomers have not only clearly observed Neptune’s auroras but also captured remarkable details of their distinctive signatures.
Moreover, scientists obtained a spectrum of Neptune’s atmosphere, allowing them to study its composition and measure the temperature of its ionosphere. Excitingly, they detected, for the first time, a prominent emission line indicating the presence of trihydrogen cation—a molecule commonly formed during auroral processes.

Sharks can produce sounds. Scientists in New Zealand observed captive rig sharks (Mustelus lenticulatus) emitting clicking noises, marking the first documented instance of sound production in sharks. These clicks are believed to result from the sharks snapping their flat, blunt teeth together—a behavior previously unrecorded in these creatures. The purpose of these sounds remains uncertain; they may serve as a defensive mechanism or a response to being startled. This finding challenges the long-held perception of sharks as silent predators and opens new avenues for understanding their behavior and communication.

Is Humanity Getting Dumber? @Science Says Yes
A recent study confirms a concerning trend: global intelligence levels have been declining since 2010. Researchers have found that many people struggle to focus on a single task, lose logical thinking skills, and spend excessive time on their smartphones.
Here are some key findings:
🔢 25% of adults in developed countries cannot solve basic math problems, with this figure rising to 35% in the U.S.
🧑🎓 Since 2015, there has been a sharp increase in 18-year-olds struggling to concentrate on a single topic.
📖 In 2022, half of those surveyed read no more than one book, while 45% of teenagers did not read at all.
The culprit? The way we consume information has changed. Social media, with its endless feeds and algorithm-driven content, overloads the brain, making it harder to seek out and process valuable information. Instead, people get stuck in an endless loop of low-value content consumption.
💡 The good news?
The brain remains highly adaptable—with effort, it’s possible to regain focus and sharpen critical thinking skills.

Olivia Farnsworth: The Girl Who Feels No Pain, Hunger, or Fatigue
Olivia Farnsworth from the UK is a unique medical case—she doesn’t feel pain, hunger, or fatigue. This rare condition is caused by a deletion in her 6th chromosome, meaning a segment of the chromosome is missing. She is believed to be the only person in the world exhibiting all three symptoms simultaneously.
The inability to feel pain is the most dangerous aspect of her condition, as she could sustain serious injuries without realizing it. Her family must constantly monitor and protect her. Additionally, her mother ensures she eats regularly, as Olivia doesn’t experience hunger signals and could easily forget to eat.
Sleep is an even greater challenge. Without medication, Olivia cannot fall asleep naturally and can stay awake for up to three days in a row. To manage this, she follows a strict regimen of sleeping aids.
Olivia’s case remains a fascinating and rare example of how genetic anomalies can dramatically alter human perception and biology.

Hints of auroral activity on Neptune were first spotted by Voyager 2 back in 1989, but concrete evidence remained elusive. Over the decades, clear visuals of auroras emerged for Jupiter, Saturn, and Uranus, leaving Neptune as the mysterious missing link—until now.
Thanks to James Webb’s exceptional sensitivity in the near-infrared range, astronomers have not only clearly observed Neptune’s auroras but also captured remarkable details of their distinctive signatures.
Moreover, scientists obtained a spectrum of Neptune’s atmosphere, allowing them to study its composition and measure the temperature of its ionosphere. Excitingly, they detected, for the first time, a prominent emission line indicating the presence of trihydrogen cation—a molecule commonly formed during auroral processes.

The IM-2 Athena lunar lander, developed by Intuitive Machines, has completed its mission in the Moon’s southern polar region. However, it did so ahead of schedule—because it tipped over upon landing. This mishap echoes last year’s incident with the company’s first lander, IM-1 Odysseus. That one, despite ending up on its side, managed to function for some time since its solar panels could still charge the batteries.
Unfortunately, IM-2 fared worse. The designated landing ellipse was just 50 meters across near Malapert Massif, but the actual deviation was much larger—250 meters, according to the company, and up to 400 meters, per NASA. Engineers noted issues with the clarity of data from the laser altimeter, and an image sent from the lander confirmed that it had come to rest on its side inside a crater. Given that this region receives only slanted sunlight, combined with the extreme cold of the lunar night and the poor orientation of the solar panels, IM-2 has no chance of waking up again.
As a result, the two small rovers and the drill meant to extract regolith from nearly a meter deep were unable to fulfill their primary missions—though at least they managed to prove they were functional.
