Confirms Johanna Teske as lead author. Confirms lower-than-expected density and 'wet lava ball' description. Confirms magma ocean recycling hypothesis."},{"url":"https://www.scientificamerican.com/article/james-webb-space-telescope-finds-atmosphere-on-lava-planet-toi-561-b/","status":"verified","findings":"Confirms Tim Lichtenberg quote: 'It's super old and ultrahot. This planet should not have an atmosphere. And it has one.' Confirms planet is twice as old as our solar system with two Earth masses. Correctly attributed to University of Groningen."},{"url":"https://www.sciencedaily.com/releases/2026/03/260322020255.htm","status":"verified","findings":"Confirms study published in The Astrophysical Journal Letters led by Carnegie Science astronomer Johanna K. Teske. Confirms orbital period of 10.56 hours, temperature discrepancy, and heat redistribution evidence."},{"url":"https://www.nature.com/articles/s41550-026-02815-8","status":"inaccessible","findings":"Nature returned HTTP 303 redirect. However, the ScienceDaily coverage of L 98-59 d references this paper and confirms the key claims about sulfur-dominated atmosphere and magma ocean. Article claims are consistent with coverage from other verified sources."},{"url":"https://www.sciencedaily.com/releases/2026/03/260317190802.htm","status":"verified","findings":"Confirms L 98-59 d is ~35 light-years away orbiting a red dwarf. Confirms detection of sulfur dioxide and hydrogen sulfide in atmosphere. Confirms planet defies traditional classification systems. Confirms 'completely different class of planet dominated by heavy sulfur compounds.'"},{"url":"https://phys.org/news/2026-03-class-molten-planet-abundant-sulfur.htm","status":"inaccessible","findings":"HTTP 403 (bot blocked).

All key claims verified against accessible sources. Temperature measurements (3,200°F vs 4,900°F), orbital period (10.56 hours), researcher quotes (Lichtenberg, Teske), planet properties (TOI-561 b mass, L 98-59 d size and distance), and sulfur compound detections all confirmed. Two sources inaccessible but claims cross-verified via other sources covering the same research.

Strong science news article covering two significant JWST discoveries. All verifiable claims check out against sources. Appropriate scope for News category at 755 words. Well-balanced structure with clear attribution and an honest accounting of open questions.
