A map of the universe ·

If you like space, you'll love my the 12,000 billion light-year map of clusters, superclusters and voids. Find the biggest nothings in Boötes and Eridanus.The largest map there is shows the location of voids and galaxy superclusters in our visible universe.

The Sky, northern hemisphere

The mysterious and incomplete sky is yours in these 100 megapixel and 10 gigapixel maps of the northern celestrial hemisphere.

Included are about 2.4 million stars from the major catalogues (HR, Hipparcos and Tycho-2). In the 10 gigapixel image, the entire 100+ million star UCAC4 catalogue is included. Canonical IAU constellation asterisms are included. About 100,000 deep sky objects are also shown. These are jittered to avoid overlap, which is why some clusters of objects appear as large globules of symbols.

In the 10 gigapixel map, labels are lovingly placed and formatted to include name, catalogue and magnitude data. The 100 megapixel map has no labels.

Stellar and deepsky object annotations taken from Vizier.
