Image: Hubble traces a galaxy's outer reaches

Believe it or not, this long, luminous streak, speckled with bright blisters and pockets of material, is a spiral galaxy like our Milky Way. But how could that be? 

Image: Hubble snaps a galactic potpourri of particles

Every now and then, the NASA/ESA Hubble Space Telescope glimpses a common object—say, a spiral galaxy—in an interesting or unusual way. A sharply angled perspective, such as the one shown in this Hubble image, can make ...

Production sites of stars are rare

Astronomers using the Nobeyama Radio Obeservatory (NRO) 45-meter telescope found that high-density gas, the material for stars, accounts for only 3 percent of the total mass of gas distributed in the Milky Way. This result ...

Astronomers decode Milky Way's violent birth

The Milky Way gobbled up a galaxy one quarter of its mass 10 billion years ago in a "violent collision" that didn't fully settle for eons, astronomers said in new research published Monday.

Astronomers map vast void in our cosmic neighborhood

An astronomer from the University of Hawaiʻi Institute for Astronomy (IfA) and an international team published a new study that reveals more of the vast cosmic structure surrounding our Milky Way galaxy.

Image: 10 million star puzzle

When observed with the unaided eye, Omega Centauri, the object in this image, appears as a fuzzy, faint star. But the blue orb we see here is, in fact, a collection of stars—10 million of them. You cannot count them all, ...

Telescope viewing suspended as protesters block Hawaii road

Astronomers have indefinitely stopped looking through 13 existing telescopes at the summit of Mauna Kea in Hawaii while protesters block the road downslope in an attempt to prevent the construction of a giant new observatory.

Gaia starts mapping the galactic bar in the Milky Way

The second release of data from the Gaia star-mapping satellite, published in 2018, has been revolutionising many fields of astronomy. The unprecedented catalogue contains the brightness, positions, distance indicators and ...

Milky Way

The Milky Way, or simply the Galaxy, is the galaxy in which the Solar System is located. It is a barred spiral galaxy that is part of the Local Group of galaxies. It is one of billions of galaxies in the observable universe.

Its name is a translation of the Latin Via Lactea, in turn translated from the Greek Γαλαξίας (Galaxias), referring to the pale band of light formed by the galactic plane as seen from Earth (see etymology of galaxy). Some sources hold that, strictly speaking, the term Milky Way should refer exclusively to the band of light that the galaxy forms in the night sky, while the galaxy should receive the full name Milky Way Galaxy, or alternatively the Galaxy. However, it is unclear how widespread this convention is, and the term Milky Way is routinely used in either context.
