Relationships, not isolated facts

This viewport is generated from the Asteria knowledge graph. Science, culture, and interpretive links remain separated by domain so visual context never changes the evidentiary meaning of a relation.

constellation

Henry Draper was an American physician and pioneer of astrophotography. In 1872 he made the first photograph showing the spectral lines of a star, Vega, and in 1880 he captured the first photograph of the Orion Nebula.

interstellar environment

Star-Forming Regions

The dense cores of molecular clouds where gravity pulls gas together into new stars, and where the heat and radiation of those young stars drive a burst of chemistry. The Orion Nebula is the nearest region of massive star formation and the most-studied example.

astrophysical object class

Emission Nebula

A cloud of interstellar gas that glows with its own light, ionised by the ultraviolet radiation of nearby hot stars so that it re-emits in characteristic lines — most famously the red of hydrogen. Emission nebulae mark regions of active star formation and include the great HII regions of the Galaxy.

astrophysical object class

HII Region

A large cloud of ionised atomic hydrogen (H II) surrounding one or more hot O- and B-type stars, whose ultraviolet light strips the electrons from the surrounding gas. HII regions are the glowing signposts of massive-star formation, and their sizes and spectra are used to trace star formation across galaxies.
