Astronomers Detect a Possible Signature of Life on a Distant Planet

This is about dimethyl sulfide in the atmosphere of exoplanet K2-18b:

https://en.wikipedia.org/wiki/K2-18b

The NYT article reports a new study in The Astrophysical Journal and links to it, but the DOI is currently not found:

https://dx.doi.org/10.3847/2041-8213/adc1c8

I also don't see the article yet under their Latest Articles:

https://iopscience.iop.org/journal/0004-637X

Here are recent articles about K2-18b from Google Scholar:

Those DOIs have a different prefix, I think it might be in Letters

https://iopscience.iop.org/journal/2041-8205

It's still not out yet though. Also journals are often rather tardy or just straight up don't register the doi at all and still put it on their site, but maybe this is an embargo thing.

edit - is it possibly this after publishing? https://arxiv.org/abs/2501.18477

Good point about the DOI prefix. I don't think it's that arXiv article, though, since it says there is no statistically significant evidence for carbon dioxide or dimethyl sulfide. This NYT article (and presumably whatever journal article it's based upon) reports high levels of dimethyl sulfide.

You're right, different authors too.

https://www.eurekalert.org/multimedia/1069012 uses the DOI in the article and says it's from

> A. Smith, N. Madhusudhan (University of Cambridge)

Here's another article on it https://www.bbc.co.uk/news/articles/c39jj9vkr34o

I think this is still under embargo, or hasn't quite been released. There's going to be some time required for visuals like on the bbc site.

https://arxiv.org/abs/2504.12267 matches the title ("New Constraints on DMS and DMDS in the Atmosphere of K2-18b from JWST MIRI") reported at https://www.eurekalert.org/news-releases/1080558, and it also matches the reported results.

Good find. The DOI resolves and the article is up now too
