But there is more. It turns out that the universe is rushing away from us. The Milky Way is not alone, together with the Andromeda Galaxy, and more than fifty dwarf galaxies, it forms the Local Group, a region of space about ten million light years in diameter: our galactic neighbourhood...
Explanation:Imaged on June 20 2022, cometC/2017 K2 (PanSTARRS)shares this wide telescopic field of view with open star cluster IC 4665 and bright star Beta Ophiuchi, near a starry edge of the Milky Way. On its maiden voyage to the inner Solar System from the dim anddistant Oort cloud, ...

The article reports on the galaxy called Leo T which is only about 600 light-years across. That is about one-sixteenth the diameter of the Milky Way. It is also 50,000 times brighter than the sun. At 1.4 million light-years from Earth, the galaxy lies far enough away that it's not...
This selection was based on the axial ratio, angular diameter, magnitude, and color limits. Flagged galaxies and objects with extreme magnitude errors were not included. The SDSS query was tailored to select relatively bright galaxies with apparent Petrosian magnitudes in the g band less than 20 ...
is the second sign of the Western Tropical Zodiac and represents the height of spring in the northern hemisphere, ruled by the planet Venus and the goddess herself in all her verdant mythological glory. Venus rules Taurus by day, and the Moon, which is exalted in the sign of the Bull, ru...
It is the largest burial mound in Scandinavia, 77 metres in diameter and over 15 metres in height. There are a number of stories associated with it, one associated with a roving sea-King Raki or… View original post1,034 more words ...
Following a study of what is in effect a miniature galaxy buried inside a normal-sized one – like a Russian doll – astronomers using a CSIRO telescope have concluded that massive black holes are more powerful than we thought.
The actual diameter of the star does vary by 60% or more, as Betelgeuse shows an unstability indicative of its ripeness to explode into a supernova (in a matter of centuries, at most). An angle of 55 mas at 427 light-years corresponds to a linear distance of 7.2 astronomical units (...
