This list contains natural objects up to apparent magnitude 3.5. All objects are listed by their visual magnitudes, and objects too close together to be distinguished are listed jointly. Objects are listed by their proper names or their most commonly used stellar designation. This list does not include transient objects such as comets, or ...
The Messier catalogue is one of the most famous lists of astronomical objects, and many objects on the list are still referenced by their Messier numbers. [1] The catalogue includes most of the astronomical deep-sky objects that can be easily observed from Earth's Northern Hemisphere; many Messier objects are popular targets for amateur ...
Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy about 12 million light-years away in the constellation Ursa Major. It has a D 25 isophotal diameter of 29.44 kiloparsecs (96,000 light-years ).
The unusually bright quasar is located 13 billion light-years away and experts say the discovery could unlock clues about our universe’s early beginnings.
The ancient object formed when the universe was less than 10% of its current age of 13.8 billion years, according to a new study. ... of a quasar — the brightest known objects in the universe ...
Superimposing picture showing sizes of the Moon and the Andromeda Galaxy as observed from Earth. Because the galaxy is not very bright from an amateur's point of view, its size is not evident. [139] [140] Under most viewing conditions, the Andromeda Galaxy is one of the most distant objects that can be seen with the naked eye, due
Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day. The black hole ...
