The collection of stars rises close to perpendicular to the plane of the spiral arms of the Milky Way. The proposed likely interpretation is that a dwarf galaxy is merging with the Milky Way. This galaxy is tentatively named the Virgo Stellar Stream and is found in the direction of Virgo about 30,000 light-years (9 kpc) away. [237]
Galactic Tick Day is an awareness and education day that celebrates the movement of the Solar System around the Milky Way galaxy. [1] [2] [3] [4]The day occurs at a regular interval of 1.7361 years (or 633.7 days), [5] which is called a galactic tick.
The Milky Way Galaxy.. The Monoceros Ring (from Greek monoceros 'unicorn') is a long, complex ring of stars that wraps around the Milky Way three times. This is proposed to consist of a stellar stream torn from the Canis Major Dwarf Galaxy by tidal forces as part of the process of merging with the Milky Way over a period of billions of years, although this view has long been disputed.

In 2003, an overdensity of stars in the region was announced to be the Canis Major Dwarf, the closest satellite galaxy to Earth. However, there remains debate over whether it represents a disrupted dwarf galaxy or in fact a variation in the thin and thick disk and spiral arm populations of the Milky Way.
While Earth is located about 26,000 light-years from what's known as the galactic center, the outer portions of the Milky Way are even further, at about 58,000 light-years from our galaxy's ...
The Gould Belt is a local ring of stars in the Milky Way, tilted away from the galactic plane by about 16–20 degrees, first reported by John Herschel and Benjamin Gould in the 19th century. [1] It contains many O- and B-type stars , and many of the nearest star-forming regions of the local Orion Arm , to which the Sun belongs.
Astronomers using the Gaia space telescope have located two ancient streams of stars that helped the Milky Way galaxy grow and evolve more than 12 billion years ago.
Composite image showing young stars in and around molecular cloud Cepheus B.. This is a list of star-forming regions located in the Milky Way Galaxy and in the Local Group.Star formation occurs in molecular clouds which become unstable to gravitational collapse, and these complexes may contain clusters of young stars and regions of ionized gas called H II regions.
