Claims of Extrasolar Spherules from Pacific Ocean Site CNEOS 2014-01-08 Disputed 14MAR2024
Claims of Extrasolar Spherules from Pacific Ocean Site CNEOS 2014-01-08 Disputed
Recently, a preprint has been posted to the arXiv site that disputes proposal that Be,La,U-rich spherules recovered form
Pacific Ocean Site CNEOS 2014-01-0 are from an extrasolar origin. Instead, they argued to be microtektites of terrestrial lateritic sandstone.
The preprint is:
Desch, S., 2024. Be, La, U-rich spherules as microtektites of terrestrial laterites: What goes up must come down. arXiv preprint arXiv:2403.05161.
https://arxiv.org/abs/2403.05161
https://arxiv.org/ftp/arxiv/papers/2403/2403.05161.pdf
The proposed extrasolar spherules are discussed in:

>This story caused a big splash on the Internet back in late-2021, but I'm still looking for a published paper.
>Has anyone heard anything more about this speculated comet impact?
Here is a follow-up article (dated Nov. 8, 2021) regarding a reported finding of impact-melt glass from a suspect "comet impact in the Atacama Desert".
