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 Milky Way was once considered an ordinary spiral galaxy. Astronomers first began to suspect that the Milky Way is a barred spiral galaxy in the 1960s. Their suspicions were confirmed by Spitzer Space Telescope observations in 2005, which showed that the Milky Way's central bar is larger than what was previously suspected. Famous examples
The Milky Way Galaxy, where the Solar System is located, is classified as a barred spiral galaxy. Edwin Hubble classified spiral galaxies of this type as "SB" (spiral, barred) in his Hubble sequence and arranged them into sub-categories based on how open the arms of the spiral are. SBa types feature tightly bound arms, while SBc types are at ...
The Milky Way galaxy is a member of an association named the Local Group, a relatively small group of galaxies that has a diameter of approximately one megaparsec. The Milky Way and the Andromeda Galaxy are the two brightest galaxies within the group; many of the other member galaxies are dwarf companions of these two.
Galactic Center. 17 45 40.04, −29° 00′ 28.1″. The Galactic Center, as seen by one of the 2MASS infrared telescopes, is located in the bright upper left portion of the image. Marked location of the Galactic Center. The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy.
To the Māori the Milky Way is the waka (canoe) of Tama-rereti. The front and back of the canoe are Orion and Scorpius, while the Southern Cross and the Pointers are the anchor and rope. According to legend, when Tama-rereti took his canoe out onto a lake, he found himself far from home as night was falling.
The total mass of the asteroid belt is significantly less than Pluto 's, and roughly twice that of Pluto's moon Charon. The asteroid belt is a torus -shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies ...
The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group—the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.
Galactic bulge. Artist's impression of the central bulge of the Milky Way [1] In astronomy, a galactic bulge (or simply bulge) is a tightly packed group of stars within a larger star formation. The term almost exclusively refers to the central group of stars found in most spiral galaxies (see galactic spheroid ).
The Solar System is located in the Milky Way, a barred spiral galaxy with a diameter of about 100,000 light-years containing more than 100 billion stars. The Sun is part of one of the Milky Way's outer spiral arms, known as the Orion–Cygnus Arm or Local Spur.
