How to get the most out of r/Astronomy

If you want to join and contribute effectively, here are practical tips:

Read the rules and pinned FAQ before posting. This avoids common pitfalls and increases the likelihood your post will be well received.

Use reputable sources for news and claims. When possible, link to original papers, NASA/ESA releases, or established science outlets.

When posting images, include acquisition details — gear, exposure, stacking, processing steps — so others can learn from your setup.

Ask focused questions. Instead of a broad "what is this?" include coordinates, time, and what you were observing.

Participate in the comments. Upvoting good explanations and adding constructive insights helps the community grow.

Examples of great content types

High-value posts often fall into these categories:

A clear, sourced summary of a new discovery with links to the paper and mission pages.

An astrophotography post that walks through the capture and editing workflow.

A well-asked observational question with data that sparks a collaborative identification or explanation.

A meta post that synthesizes several sources and explains implications of a discovery in plain language.

Posts that lack context, sources, or basic details tend to receive corrective comments or are removed by moderators.
