Earth recently captured a small asteroid known as 2024 PT5, temporarily transforming it into a second moon. This rare event was confirmed by astronomers from Massachusetts Institute of Technology (MIT) and the Complutense University of Madrid, offering a glimpse into these elusive “mini-moons” that Earth occasionally holds within its orbit. However, Earth’s newly acquired companion is not here to stay. In a matter of weeks, by mid-November, 2024 PT5 is expected to slip out of Earth’s gravitational hold and resume its journey around the sun.

How Scientists Discovered 2024 PT5

This asteroid was first identified on 7 August 2024 by NASA’s Asteroid Terrestrial-impact Last Alert System (ATLAS) at Hawaii’s Haleakala Observatory. Subsequent observations were conducted by astronomers from the Complutense University using a high-powered telescope located in Sutherland, South Africa. While such temporary moons have been observed before, they are typically hard to detect due to their small size and fleeting appearance.

Richard Binzel, a renowned astronomer at MIT, highlighted that these transient moons are easier to track now with advanced telescope technology. “We’re only starting to observe these small objects with enough regularity to learn more about them,” he explained. As Earth.com reported, the capture of 2024 PT5 has piqued the interest of astronomers eager to study near-Earth objects in greater depth.

Why Mini-Moons Are Important

While our primary moon spans an impressive 2,159 miles in diameter, 2024 PT5 is a mere 37 feet across — rendering it invisible without a telescope of at least 30 inches in diameter. The limited visibility of these mini-moons shows us the challenge in observing them. As noted by William Blackmore, Planetarium Director and Astronomy Instructor at Mt. Hood Community College, “each mini-moon offers a unique learning opportunity.” He pointed out that by studying these objects, scientists can make better methods for tracking potential asteroid threats to Earth.

Potential for Future Exploration

While the chances of mining such asteroids remain distant, Blackmore envisions future missions using probes or satellites to monitor these fleeting visitors. Understanding mini-moons like 2024 PT5 could pave the way for intercepting larger asteroids in the future, a critical step in safeguarding Earth.
In a few short weeks, 2024 PT5 will leave Earth’s orbit.

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.
