TON 618 (abbreviation of Tonantzintla 618) is a hyperluminous, broad-absorption-line, radio-loud quasar, and Lyman-alpha blob [2] located near the border of the constellations Canes Venatici and Coma Berenices, with the projected comoving distance of approximately 18.2 billion light-years from Earth.
TON 618: TON 618 is a very distant and extremely luminous quasar—technically, a hyperluminous, broad-absorption line, radio-loud quasar—located near the North Galactic Pole in the constellation Canes Venatici.

Westbrook Nebula (CRL 618) is a bipolar protoplanetary nebula which is located in the constellation Auriga. It is being formed by a star that has passed through the red giant phase and has ceased nuclear fusion at its core. This star is concealed at the center of the nebula, and is ejecting gas and dust at velocities of up to 200 km/s. [3]
An image of Barnard 68, a dark nebula mistakenly used to refer to the Boötes Void.. The Boötes Void has been often associated with images of Barnard 68, [7] a dark nebula that does not allow light to pass through; however, the images of Barnard 68 are much darker than those observed of the Boötes Void, as the nebula is much closer and there are fewer stars in front of it, as well as its ...
The 618 area code dates to 1947. A new 730 area code overlaying the current 618 area code will be introduced in southern Illinois next year, the Illinois Commerce Commission announced Wednesday.
