APOD: 2026 May 14 Б The Messier Catalog at Uniform Scale
Explanation:
What are some of the most interesting astronomical objects you can see in the night
sky?
Armed with a good pair of binoculars or a small telescope, if you live in the
Northern Hemisphere, you can look for the
very popular
objects in the Messier
Catalog.
Most of them, but not all, are also visible from the southern half of the Earth.
The featured image shows
all 110 objects in the catalog at uniform scale -- the same magnification.
Charles
Messier created the catalog in the 18th century.
He was interested in comets,
and his catalog was a list
of known comet-like "objects
to avoid" in the sky when observing or hunting for comets.
The deep sky objects
in the catalog include a supernova
remnant (the
Crab Nebula, M1), other galaxies (such
as
Andromeda, M31), nebulae (e.g. the
Orion
Nebula, M42, a star-forming region) and stellar clusters (such as the
Pleiades,
M45, a bright young open cluster).
