Evidence of a 12,800-year-old shallow airburst depression in Louisiana

https://www.scienceopen.com/hosted-document?doi=10.14293/ACI.2025.0004

ScienceOpenEvidence of a 12,800-year-old Shallow Airburst Depression in Louisiana with Large Deposits of Shocked Quartz and Melted Materials<p xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="first" dir="auto" id="d16462011e451">We report evidence of a likely low-altitude cosmic airburst near Perkins, Louisiana, associated with semi-consolidated deposits containing abundant shocked quartz grains, a classical impact indicator, along with spherules, meltglass, and microbreccia. Analytical techniques employed on these materials include optical microscopy, the universal stage, electron microscopy (SEM, TEM, and STEM), cathodoluminescence, laser ablation (LA-ICP-MS), neutron activation (INAA), and radiometric dating. These analyses reveal that the deposits exhibit morphological and compositional similarities to known impact-related proxies. Radiocarbon dating and 40Ar/39Ar analyses constrain the likely age of deposition to between 30,000 and 10,000 calibrated years BP, with a concentration of dates clustering around 12,800 years BP (12,835-12,735 cal BP), coinciding with the age range of the Younger Dryas Boundary (YDB). Spherule and meltglass abundances, along with evidence of high-temperature mineral transformations, are consistent with the effects of a high-energy airburst or impact. Hydrocode modeling suggests that a touch-down airburst could plausibly account for the observed shallow depression, material dispersal patterns, and geochemical signatures. Our study suggests that a 300-m-long lake/depression at the Perkins site represents North America’s first identified YDB-age airburst crater. </p>

Eight edge-on disk galaxies observed by the James Webb Space Telescope, split in two rows. Each disk galaxy is centered within a square frame and lies against the black background of space. They appear as thin lines with a slight bulge in their centers. A few of the galaxies are horizontal or vertical, but many are angled diagonally.

Frigid Exoplanet in Strange Orbit Imaged by NASA’s Webb https://science.nasa.gov/universe/exoplanets/frigid-exoplanet-in-strange-orbit-imaged-by-nasas-webb/ #NASA #Astrophysics #Exoplanets #GoddardSpaceFlightCenter #JamesWebbSpaceTelescopeJWST #ScienceResearch #StudyingExoplanets #TheUniverse

This image shows the exoplanet 14 Herculis c. The view is mostly black, with very faint red splotches in the central region of the image. At the center of the image, there is a black circle, and in the center of that, there is a star symbol representing a real star. This black circle blocks the light from the host star. To the lower right of the circle is a fuzzy bright orange circle, which is the exoplanet.

Center of image contains two oblong blue ovals that intersect, representing mutual orbit of two brown dwarfs in the horizontal plane. Perpendicular to these, and crossing both, is a larger red oval representing a planetary orbit in the vertical plane. This illustration is intended to show the planet in a polar orbit around the two brown dwarfs, known as a "circumbinary" orbit.
