Read previewYet another study is calling into question a Harvard professor's claims that metallic balls discovered under the ocean may have been made by aliens . Johns Hopkins University-led (JHU-led) research said a blip on the seismometer that Loeb used to pinpoint the crash site may simply have been caused by the vibrations of a passing truck. AdvertisementPinpointing the crash siteIn 2019, Loeb and his team searched databases for unusual meteors that were moving rapidly. The meteor, dubbed by Loeb's team IM1, was first spotted by the Department of Defense's (DoD) sensors. Loeb's team recovered 805 spherules.

☆ Surprise: An ‘Extraterrestrial’ Gadget Was Something More Familiar

In January of 2014, a meteor fell from space off the coast of Papua New Guinea. Last fall, Benjamin Fernando, a planetary seismologist at Johns Hopkins University, led a team that re-examined the nearby seismic signals and concluded that they were not evidence of the extraterrestrial, or anything close to it. Recently, he sat down with The New York Times to preview what his team had found. In 2014, a meteor entered the atmosphere and went “bang.” Sometimes, you hear these meteors on seismometers. Avi Loeb wrote a paper to say that he’d found the seismic signal from this meteor and that he’d used it to locate exactly where the meteor debris fell.

☆ Yes, the moon is shrinking but that's not the disturbing news scientists discovered that could threaten future NASA missions

AdvertisementDanger at the lunar south poleArtemis III plans to land astronauts near the moon's south pole , which contains water ice, among other vital resources. Even small tremors at the moon's south pole could trigger landslides, according to a NASA press release, which may be dangerous to astronauts. Asteroids and comets have also broken up the lunar surface, Nicholas Schmerr, a co-author on the study, said in a statement . Astronaut James B. Irwin, lunar module pilot, works at the Lunar Roving Vehicle during the first Apollo 15 lunar surface extravehicular activity (EVA). The setback will likely also delay NASA's later missions and the agency's aspirations to build a permanent base at the moon's south pole.

☆ The moon is shrinking, and it could be a problem for astronauts

On the lunar surface, however, it’s a different story. “We also knew that the largest of the shallow moonquakes detected by the Apollo seismometers was located near the south pole. As part of the mission, two astronauts will spend about a week living and working on the lunar surface. They can be an opportunity to better study the moon as we do on the Earth with earthquakes,” Husker said. Studying moonquakes at the south pole will tell us more about the Moon’s interior structure as well as its present-day activity.”

☆ Mercury is slowly shrinking, and it's giving the planet wrinkles

AdvertisementAdvertisementMercury, the smallest planet in the solar system, is getting even — and getting more wrinkles as it does, a new study suggests. Mercury is wrinkling like an old appleLike any other planet, Mercury is losing heat. The study, published in Nature Geosciences on Monday, identified 48 definite and 244 likely grabens on pictures snapped by NASA's MESSENGER probe in 2015.

☆ Small moonquakes caused by Apollo lunar lander module, study finds
▼ + stars: | 2023-09-14 | by ( Jackie Wattles | ) edition.cnn.com time to read: +6 min

CNN —A spacecraft left behind by US astronauts on the lunar surface could be causing small tremors known as moonquakes, according to a new study. The lunar surface is an extreme environment, oscillating between minus 208 degrees Fahrenheit (minus 133 degrees Celsius) in the dark and 250 degrees Fahrenheit (121 degrees Celsius) in direct sun, according to a news release about the study. Marusiak was not directly involved in the study, though she did have contact with the authors as a fellow expert in lunar seismology. “Every lunar morning when the sun hits the lander, it starts popping off,” said study coauthor Allen Husker, a research professor of geophysics at Caltech, in a statement. It’s important to note a key difference between the moon and Earth: On the lunar surface, there are no shifting tectonic plates that might cause catastrophic events.

☆ Mysterious tremors on the moon have been traced back to an unexpected source

Data showed a mysterious quake happening every lunar morning, and scientists weren't sure why. A new study has found morning tremors are coming from the Apollo 17 lunar lander base. They discovered that some of the tremors were being produced by the descent stage of the Apollo 17 lunar module, left behind on the lunar surface 51 years ago. AdvertisementAdvertisementBut each morning, scientists also saw bizarre waves popping up every few minutes. By triangulating the signal, they were able to figure out the source of the mysterious tremors.

Tectonic plates under the Americas, Europe, and Africa are separating as the Atlantic Ocean grows wider. The tectonic plates undergirding the Americas are separating from those beneath Europe and Africa. Fragmented into tectonic plates, the Earth's crust fits together like a puzzle. Seafloor spreading, which occurs at divergent tectonic plates that are pulling apart like the MAR, is another.

☆ What the Great Lisbon Earthquake of 1755 Tells Us About This Week’s Disaster
▼ + stars: | 2023-02-09 | by ( Mark Molesky | ) www.wsj.com time to read: +1 min

The disaster is a reminder that large segments of the world’s population are as vulnerable to major earthquakes today as they were centuries ago. In fact, the scenes in Turkey are tragically similar to those reported on Nov. 1, 1755, when a massive earthquake hit Lisbon, the capital of Portugal, at approximately 9:45 a.m. The Great Lisbon Earthquake, as it became known, was one of the most consequential quakes in modern history, and its story can shed light on the challenges survivors face today—practical, political and even philosophical. There were no reliable seismometers in the 18th century, but the Great Lisbon Earthquake is estimated at between 8.5 and 9.2 on the moment magnitude scale—at least five times stronger than the initial quake in Turkey, which registered 7.8. Like the earthquakes in Turkey, the Lisbon temblor came with little or no warning.

☆ Explainer: Why was the Turkey-Syria earthquake so bad?

[1/2] A damaged vehicle is seen on top the rubbles after an earthquake in Iskenderun, Turkey February 6, 2023. The epicentre was about 26 km east of the Turkish city of Nurdagi at a depth of about 18 km on the East Anatolian Fault. During the 20th century, the East Anatolian Fault yielded little major seismic activity. But in 1822, a 7.0 quake hit the region, killing an estimated 20,000 people. The East Anatolian Fault is a strike-slip fault.

☆ Mars may have molten lava, scientists discover from quakes detected by NASA's Insight lander

NASA's InSight lander has detected Mars quakes that mostly come from one region: Cerberus Fossae. But now, using a seismometer on NASA's InSight lander, scientists have discovered the first evidence of molten lava deep below the Martian surface. A series of Mars quakes clued the scientists in to the potential lava hotspot. The biggest Mars quakes point to an underground chamber of magmaInSight has detected more than 1,300 Mars quakes since landing on the red planet in 2018. To get the global picture of Mars quakes and volcanic activity, NASA would need to send more seismometers to the red planet.
