In Siberia, a massive crater emerged explosively in the tundra, sending ice and rock hundreds of feet away and creating a large circular scar. This event marked the 17th crater discovered in the Yamal and Gyda peninsulas since 2013, attracting significant scientific interest. The craters are believed to be linked to climate change, with modern tools like drone photography, 3D modelling, and artificial intelligence (AI) aiding in their analysis.

Scientific Exploration

Dr Evgeny Chuvilin, lead research scientist at the Skolkovo Institute of Science and Technology’s Centre for Hydrocarbon Recovery in Moscow, highlighted that the new crater was exceptionally well-preserved, providing a rare opportunity to study a “fresh” crater, as per a CNN report. For the first time, researchers used a drone to explore the crater’s depths, reaching 10 to 15 metres below the surface. This allowed them to create a detailed 3D model of the crater, which is 30 metres deep.

Findings and Hypotheses

Igor Bogoyavlensky from the Oil and Gas Research Institute of the Russian Academy of Sciences, who operated the drone, described the difficulty of controlling it from the edge of the deep crater. The 3D model revealed unusual grottoes in the crater’s lower section, confirming the theory that methane gas builds up in an underground cavity, causing an explosive blowout and forming the crater.

Methane Sources and Climate Impact

The source of the methane remains uncertain; it may come from deep within the Earth or closer to the surface, or both. Permafrost, which stores large amounts of methane, is weakening due to rising Arctic temperatures, facilitating gas escape. Satellite imagery estimated the crater’s formation occurred between May 15 and June 9, 2020, with the crater first identified on July 16, 2020.

Future Research and Monitoring

Predicting these blowouts remains challenging, but scientists at the Woodwell Climate Research Center in Massachusetts are developing algorithms to track landscape changes and forecast potential crater formations. Their model has successfully predicted new craters and underscores the dramatic changes in the Arctic region.

Massive Steam Plume Spotted at Alaska’s Mount Spurr as Volcano May Erupt Soon

Massive Steam Plume Spotted at Alaska’s Mount Spurr as Volcano May Erupt Soon

A large steam plume has been seen emerging from Mount Spurr in Alaska, signalling increased volcanic activity. Images shared by the Alaska Volcano Observatory (AVO) on March 28 confirmed steam and gas emissions visible from the volcano’s summit and a northern vent. The volcano is located around 80 miles west of Anchorage and stands at 11,070 feet high. The experts have revealed that there could be a possible eruption in the coming weeks or months. However, nothing is certain yet.

Increased Signs of Unrest Reported

According to the latest update by the Alaska Volcano Observatory steam was observed rising from the summit on March 26. A smaller plume was also recorded from a fumarole on the volcano’s northern flank. No immediate changes in seismic activity or gas levels were detected during these observations as per the AVO statement.

The AVO had earlier mentioned in a March 11 update that a noticeable rise in gas emissions indicates fresh magma has moved into the crust beneath Mount Spurr. This has led scientists to assess the chance of an eruption in the near future. The observatory clarified that the exact timing of any eruption cannot be predicted yet.

Hazards and Possible Alerts

The observatory has cautioned that the volcano’s alert level might be raised if there are further signs of escalation. According to AVO, this may include persistent seismic tremors, increased gas emissions or visible surface changes. If an eruption occurs, possible hazards include ash clouds impacting flights, ashfall across nearby areas, pyroclastic flows and mudflows known as lahars.

The volcano last erupted in 1992. That eruption resulted in heavy ashfall and affected air travel in the region. AVO has advised residents and visitors to stay informed and follow safety instructions if alerts are raised.

Study Identifies Plasma Formation as a Pseudostreamer

Study Identifies Plasma Formation as a Pseudostreamer

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 Launches 27 Starlink Satellites on Falcon 9 Rocket, Booster Lands Safely

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.
