Seismic activity around Iceland’s Bárðarbunga volcano has increased dramatically, with over 130 earthquakes recorded within a span of five hours. The tremors, which began early on January 14, included a significant 5.1 magnitude quake. The Bárðarbunga system is among Iceland’s largest volcanic zones, and experts are closely monitoring the situation for potential eruptions, particularly given the region’s history of powerful volcanic activity. Its most recent eruption, from 2014 to 2015, was the country’s largest in over 300 years.
Bárðarbunga’s Volcanic Potential
According to the Icelandic Meteorological Office (IMO), as reported by Live Science, Bárðarbunga is an expansive system extending roughly 190 kilometres in length. Its central stratovolcano, largely covered by ice, is marked by a massive caldera filled with a glacier. This region’s eruptions have historically been significant, with lava fields forming vast expanses such as Holuhraun, the result of the 2014 event. That eruption not only created a lava field larger than Manhattan but also released considerable amounts of toxic gas into the atmosphere.
Expert Analysis of Recent Activity
IMO representatives have stated that Bárðarbunga is exhibiting “unusually large” seismic activity, though predicting the exact outcome remains challenging. Several scenarios have been proposed, ranging from eruptions outside the caldera, similar to the 2014 event, to more explosive activity beneath the glacier. Glacial outburst floods and ash emissions are potential outcomes if an eruption occurs within the caldera.
Implications and Monitoring
Months of heightened seismic activity in the region had already been noted, but the recent swarm has intensified concerns. Scientists and officials are now focused on understanding whether the earthquakes signal magma movement or tectonic shifts unrelated to an imminent eruption. Bárðarbunga’s unique geological features, including its interaction with the glacier, make it a complex system to monitor, requiring continued observation and analysis.

A towering spiral of plasma has been recorded extending millions of kilometres from the Sun. The video was taken by the European Space Agency’s Solar Orbiter during an eight-hour period on October 12, 2022. A coronal mass ejection caused the plasma to rise from the Sun’s surface. The footage captured something which was never observed before. It showed a swirling motion in the solar wind. As per the latest report, scientists also recorded bright streaks that were moving across the frame. Researchers also revealed that these streaks appeared as pixelated lines, which might also ressemble like UFOs. Scientists later confirmed they were distant stars visible due to the imaging process.
Study Identifies Plasma Formation as a Pseudostreamer
The study published in The Astrophysical Journal revealed that the massive structure that appeared in the photos was a large pseudostreamer. It was formed near the Sun’s north pole after a solar flare erupted. The report further highlighted that the plasma reached 1.5 times the Sun’s width and remained visible for three hours. Scientists believes the twisting movement of the plasma was due to Alfvénic fluctuations. These fluctuations happen when waves of charged particles respond to magnetic disturbances. Scientists says the pseudostreamer’s location influenced its unique shape. Magnetic fields at the Sun’s poles are stronger than those near the equator.
Unusual Streaks Explained
The video also showed bright, half-dark lines crossing the screen. These lines appeared to move in a pattern similar to arcade game graphics. ESA confirmed that these were distant stars. The video’s editing technique made them appear as streaks rather than points of light. The Solar Orbiter’s movement against the background created this effect.
Solar Activity Expected to Intensify
The Sun is currently experiencing solar maximum. Flares and solar winds have increased since early 2024. The pseudostreamer in the video formed before this peak. Scientists were surprised by its early appearance. ESA’s Solar Orbiter continues to capture detailed images of solar wind. NASA’s Parker Solar Probe and ESA’s Proba-3 mission are also studying these phenomena. More extreme solar winds are expected in the coming years.

SpaceX has sent another batch of satellites into orbit. On April 3, a Falcon 9 rocket launched 27 Starlink satellites from Vandenberg Space Force Base in California. The rocket lifted off at 9.02 p.m. Eastern Time and was followed by a successful landing of the first-stage booster on a drone ship stationed in the Pacific Ocean. This booster had already been used on four earlier flights. The satellites are expected to be deployed nearly an hour after takeoff if mission steps proceed as planned. The launch formed part of SpaceX’s continued effort to expand its low Earth orbit network.
Details from the Launch Mission Description
According to the mission information provided by SpaceX, the launch marked the fifth use of the same Falcon 9 booster. The drone ship used for recovery was named “Of Course I Still Love You”. This reusable system has become a routine part of SpaceX operations. The booster’s return was completed around eight minutes after liftoff. The launch contributed to the growing total of Starlink satellites which is aimed at building a global broadband network.
Launch Activity in 2025
This latest mission has brought the number of Falcon 9 launches in 2025 to 38. About two-thirds of those have supported the expansion of the Starlink constellation. Earlier this week, two separate launches were also completed. One of them included the Fram2 private astronaut mission, which carried crew members into orbit over Earth’s poles. That mission marked a new milestone in human spaceflight.
Starlink Satellite Network
Over 7100 satellites are now part of the Starlink constellation. The system is already the largest of its kind. SpaceX continues to work on expanding its coverage by launching more satellites regularly. The objective remains to provide consistent internet access worldwide, especially in regions with limited connectivity options.
