Last updated: 10 August 2026.

Educational use

Astronomy Times provides educational information and calculation tools. Results may use rounded source values, simplified models or mean astronomical quantities. Do not treat the site as a substitute for a professional ephemeris, observatory planning system, spacecraft-navigation product or scientific data pipeline.

Acceptable use

You may use the public site for ordinary personal, educational and research-reference purposes. You must not attempt to disrupt the service, bypass security controls, send automated abuse through forms or probe private configuration and credentials.

Intellectual property

Original site code, interface design, text and illustrations are protected by applicable intellectual-property laws. Scientific facts and mathematical relationships are not claimed as proprietary. Third-party names and source material remain the property of their respective owners.

Availability and changes

Tools, datasets and pages may change when calculations improve, source values are revised or technical requirements change. The site may be unavailable temporarily for maintenance or hosting problems.

External sources

Links to scientific institutions are provided for verification and further reading. Astronomy Times does not control those external websites.
