Breaking News: Meteors Strike the Moon, Captivating Astronomers and Skywatchers Alike!
In an extraordinary celestial event, two brilliant meteors collided with the moon's surface, leaving astronomers and enthusiasts in awe. Japanese astronomer Daichi Fujii, curator of the Hiratsuka City Museum, captured these rare moments on video, shedding light on the dynamic nature of our lunar neighbor.
The Lunar Flashes: A Brief but Brilliant Display
On Thursday, October 30th, and again on Saturday, November 1st, Fujii's cameras, trained on the moon's nightside, recorded the meteors' impact. These flashes, visible from Earth for a mere instant, were the result of space rocks hurtling towards the moon at incredible speeds, creating brief yet dazzling explosions of light.
Taurid Meteor Showers: A Celestial Spectacle
As we approach the peak of the Southern Taurid meteor shower on November 5th, and with the Northern Taurids following suit on November 9th, Earth's skies are already aglow with meteors. Interestingly, it seems the moon is also experiencing its share of these cosmic visitors. Fujii's recordings, shared on his X account, offer a unique perspective on these lunar impacts.
Impact Details: Unraveling the Mystery
The first collision occurred at 8:30 p.m. Japan Standard Time on October 30th, with the second following at 8:49 p.m. on November 1st. Fujii's calculations suggest that the October 30th flash occurred east of the Gassendi Crater, with the impactor likely part of the Taurid meteor stream. The meteor struck the moon at a velocity of 27 km/s (60,000 mph) and an angle of 35 degrees, with an estimated mass of 0.4 pounds (0.2 kilograms). This impact created a crater approximately 10 feet (3 meters) wide and produced a flash lasting a mere 0.1 seconds.
Fujii noted, "The pixels were saturated, indicating the flash might have been even brighter than the recorded data suggests."
The second flash, on November 1st, appeared west of Oceanus Procellarum, one of the moon's largest lunar maria.
The Taurid Connection: A Controversial Interpretation
While it remains unconfirmed whether these impacts are linked to the Taurid meteor showers or are sporadic events, the timing aligns with the showers' period of heightened activity. This adds a layer of intrigue to the story, prompting further discussion and analysis.
Fujii's Legacy: A Leading Recorder of Lunar Impacts
Fujii's observations are part of a series of lunar impact recordings he has made since 2011, with continuous observations since 2020. Using his 20cm telescope, Fujii typically detects one impact flash every few dozen hours of observation. Due to the brief visibility of the thin crescent moon and the presence of thin clouds, he observes only a few dozen flashes per year. To date, Fujii has documented a total of 60 flashes.
The Moon's Unique Environment: A Contrast to Earth
Unlike Earth, which is protected by a thick atmosphere that vaporizes most meteors before they reach the ground, the moon's virtually non-existent atmosphere offers no such defense. This means meteors crash into the lunar surface at incredible speeds, ranging from 45,000 to 160,000 mph (20 to 72 km/s), releasing powerful bursts of light and heat upon impact. Even small meteoroids, weighing just a few pounds, can create craters tens of feet across and eject significant amounts of lunar soil and rock.
For instance, a rock with a mass of 11 pounds (5 kilograms) can gouge a crater over 30 feet (9 meters) wide and eject over 75 metric tons of lunar material, as per NASA's estimates.
