Key factors

• + Longevity and Track Record — Founded in 1991 as a radio program; over 30 years of science communication with consistent focus and no major credibility-damaging scandals.
• + Scientific Source Reliance — Articles consistently cite and link to peer-reviewed studies, NASA, NOAA, ESA, and other authoritative scientific bodies, grounding claims in primary sources.
• + Expert Contributors — Content is produced by science journalists and contributors with domain-relevant backgrounds, including astronomers and science communicators.
• • Not Peer-Reviewed — EarthSky is a science journalism outlet, not an academic journal. It translates science for public audiences, which introduces some simplification but is appropriate to its mission.
• + Media Bias Fact Check Rating — Rated 'High' for factual reporting and classified as 'Pro-Science' by MBFC, with no documented history of publishing misinformation or politically motivated distortions.
• + Nonprofit/Mission-Driven Model — Operates as a science education nonprofit, reducing commercial pressure to sensationalize or distort science for clicks.
• • Limited Investigative Journalism — EarthSky is primarily an explainer and science news aggregator rather than an investigative outlet; it does not typically break original research or conduct independent investigations.
• • Corrections Policy Transparency — Corrections are made when errors are identified, but a highly visible, formalized public corrections policy is not prominently featured on the site.

Editorial standards

EarthSky maintains editorial standards appropriate to a science journalism nonprofit. Articles are bylined and contributors are identified. Content is tied to peer-reviewed research and institutional sources. The outlet has a clear editorial mission centered on science education and public literacy. While it does not publish the exhaustive editorial guidelines seen at major newspapers, its consistent pro-science, evidence-based approach across 30+ years demonstrates institutional commitment to accuracy. It does not mix opinion advocacy with factual science reporting in a misleading way.

Fact-checking

EarthSky has a strong factual track record with no documented patterns of publishing misinformation or retracted stories of significance. Media Bias Fact Check rates it as 'High' for factual reporting. As a science-focused outlet that primarily reports on consensus scientific findings and cites primary institutional sources, it has a low error profile. Errors, when they occur, tend to be minor inaccuracies in the translation of complex science for lay audiences rather than fabrications or politically motivated distortions.
