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 that cannot be individually distinguished by the naked eye.
The Pleiades ( / ˈpliː.ədiːz, ˈpleɪ -, ˈplaɪ -/ ), [8] [9] also known as the Seven Sisters and Messier 45, reflects an observed pattern formed by those stars, in an asterism of an open star cluster containing middle-aged, hot B-type stars in the northwest of the constellation Taurus.
1995 — First detection of small-scale structure in the cosmic microwave background. 1995 — Hubble Deep Field survey of galaxies in field 144 arc seconds across. 1998 — The 2dF Galaxy Redshift Survey maps the large-scale structure in a section of the Universe close to the Milky Way. 1998 — The Hubble Deep Field South is compiled.
The best time to see the Milky Way is up to a week before and within days after a new moon to avoid excess light in the night sky. Through the remainder of this summer into early fall, a new moon ...
The Sagittarius Dwarf Spheroidal Galaxy (Sgr dSph), also known as the Sagittarius Dwarf Elliptical Galaxy (Sgr dE or Sag DEG), is an elliptical loop-shaped satellite galaxy of the Milky Way. It contains four globular clusters in its main body, [8] with the brightest of them— NGC 6715 (M54)—being known well before the discovery of the galaxy ...
Story at a glance. The center of our galaxy is visible in July and August for those in the Northern Hemisphere. A camera that allows you to take long-exposure photos can pick up more colors and ...
In 2022, study coauthor Hans-Walter Rix and his colleagues used Gaia to peer into the heart of the Milky Way and discovered the oldest stars ever found in the galaxy during their “galactic ...
The Milky Way has several smaller galaxies gravitationally bound to it, as part of the Milky Way subgroup, which is part of the local galaxy cluster, the Local Group.. There are 61 small galaxies confirmed to be within 420 kiloparsecs (1.4 million light-years) of the Milky Way, but not all of them are necessarily in orbit, and some may themselves be in orbit of other satellite galaxies.
