The Rhythm of the Spheres

Reading the Night Sky

Wandering in Astronomy

The night sky is the oldest pattern of man, and every culture reads it differently. The stars above keep silent time, moving to a rhythm we are just now beginning to understand. Astronomy is where math, science, art, music, and words meet in a wondrous collision. In this section of our site, learn the basics of astronomy: from how a star chart is made, to projections and art that map the night sky, to how an astrolabe works just like it did thousands of years ago. Watch the North Star shift across centuries, explore how one sky has been mapped by many traditions, read what happened on this day in space, and see tonight’s moon for your location.

Map the Stars

The math behind star charts, with a projection explorer and a working astrolabe.

The Moving Sky

How the sky shifts across centuries, with a precession clock you can run.

The Traditions

One sky reads many ways, with a same-sky overlay of the world’s constellations.

This Day in the Stars

The sky’s events, discoveries, and lore tied to today’s date.

The Moon Tonight

Its phase and face, drawn live for where you’re standing.

LDN 1295: The Giraffe Nebula

See this entry on NASA's APOD โ†’
What does this image look like to you? Many see aย giraffeย facing right, with neck stretched high and long legs mid-stride (but some may see aย squirrelย instead). Theย featured imageย showsย LDN 1295, also called the Giraffe Nebula, in the constellation of the mythical queen of Aethiopia (Cassiopeia). It is an object in theย Lynds Catalogueย ofย Dark Nebulas, compiled inย 1962ย by American astronomerย Beverly Lynds, a pioneer for women in astronomy and astrophysics.ย Dark nebulasย are interstellarย clouds of dust and gasย that block the visible light of the starsย behind them. Theseย nebulasย are often faint and challenging targets for astrophotographers. Why do we see animal shapes and faces in nebulas, clouds, and pretty muchย everywhere? It is due toย pareidolia, our tendency to look forย familiar patterns. Pareidolia may provide animals with anย evolutionary advantage, for example in identifying (and avoiding) predators.

APOD's main NASA site isย movingย : Fromย apod.nasa.govย toย science.nasa.gov/apod
