Over 1000 years ago, Persian astronomer Abd al-Rahman al-Sufi published humanityБs oldest known record of the Andromeda Galaxy in "The Book of Fixed Stars" (Bodleian Library MS.

A mere 2.5 million light-years away the Andromeda Galaxy, also known as M31, really is just next door as large galaxies go. So close and spanning some 260,000 light-years, it took 11 different...

The Comet and the Galaxy
25.11.1997

The Moon almost ruined this photograph. During late March and early April, Comet Hale-Bopp passed nearly in front of the Andromeda Galaxy. Here the Great Comet of 1997 and the Great Galaxy in Andromeda were photographed together on March 24th. The problem was the brightness of the Moon.

The Galaxy Between Two Friends

A Little Drop of Galaxy
27.03.2020

A drop of water seems to hold an entire galaxy in this creative macro-astrophotograph. In the imaginative work of cosmic nature photography a close-up lens was used to image a previously made picture of a galaxy, viewed through a water drop suspended from a stem.
