About

What this is

Deep Sky Journal is a personal archive of deep sky imagery — a curated catalog of nebulae, galaxies, star clusters, and solar system objects. All images are sourced from ESA/Hubble and ESA/Webb public archives under the Creative Commons Attribution 4.0 International license.

The archive started as a way to keep a personal reference of objects I find most visually compelling or scientifically interesting. Over time it became a reasonably organized collection worth sharing.

Image sources

All images in this archive come from two primary sources:

• ESA/Hubble — the European Space Agency’s public image archive at esahubble.org, operated in partnership with NASA
• ESA/Webb — the James Webb Space Telescope public archive at esawebb.org

Both archives release imagery under the Creative Commons Attribution 4.0 International (CC BY 4.0) license. Credit is attributed on every object page.

Object selection

Objects are selected based on a mix of criteria: exceptional image quality, scientific significance, and personal preference. The catalog is not exhaustive — it reflects what I find interesting rather than any systematic survey.

Current catalog: nebulae (emission, planetary, supernova remnants), spiral and elliptical galaxies, globular and open clusters, and a handful of solar system bodies captured at high resolution.

Technical notes

Images are reproduced at high resolution for archival quality. Thumbnails in the gallery grid are scaled versions of the originals. Full-size images are typically 4000–8000 pixels on the long axis.

Object data (distance, apparent size, constellation) is sourced from the original ESA caption data and cross-referenced with the SIMBAD astronomical database where available.
