Most things visible to the naked eye in the sky are part of it, including the Milky Way composing the Zone of Avoidance. [12] Large Magellanic Cloud: 0.9 160 kly (49 kpc) Dorado/Mensa: Visible only from the southern hemisphere. It is also the brightest patch of nebulosity in the sky. [12] [13] [14] Small Magellanic Cloud (NGC 292) 2.7 200 kly ...

In this map of the Observable Universe, objects appear enlarged to show their shape. From left to right celestial bodies are arranged according to their proximity to the Earth. This horizontal (distance to Earth) scale is logarithmic.
The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars in other arms of the galaxy, which are so far away that they cannot be individually distinguished by the naked eye.
Many people have seen a rainbow arch across the sky, creating a ribbon of colors as rain falls nearby, but few have seen two at once. Rainbows appear when sunlight is reflected by raindrops ...
The universe's size is unknown, and it may be infinite in extent. [14] Some parts of the universe are too far away for the light emitted since the Big Bang to have had enough time to reach Earth or space-based instruments, and therefore lie outside the observable universe. In the future, light from distant galaxies will have had more time to ...
It takes all the colors of the rainbow for us to see it that way. It happens because of something called the Rayleigh effect, or Rayleigh scattering, named after a British scientist who first ...
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
