A team of Brazilian astronomers were surprised when they investigated a seemingly empty spot in the Milky Way and found a stellar nursery containing 2 clusters of stars.

A cluster of young, pulsating stars discovered in the far side of the Milky Way may mark the location of a previously unseen dark-matter-dominated dwarf galaxy hidden behind clouds of dust.

Citizen scientists scanning thousands of images from the Spitzer Space Telescope helped NASA scientists discover mysterious objects which have now been identified as a phase of massive star formation, officials at the US space agency announced on Tuesday.

A massive, high-definition panorama taken by the Hubble Space Telescope is being called the largest picture ever taken, and it shows Andromeda in unprecedented detail, depicting over 100 million individual stars and traversing a 48,000 light-year-long stretch of the galaxy.

In four billion years, a mere blink of an eye by universal standards, planet Earth will be part of a galactic collision when our Milky Way will smash into the Andromeda spiral galaxy. Scientists got a preview of that event earlier this week.

Detailed analysis of different stellar populations in the disk of Andromeda suggests the galaxy may have had a far more violent history of mergers with smaller galaxies than the Milky Way, researchers from the University of California, Santa Cruz report in a new study.

Don’t look now, Milky Way, but it appears that there’s a new dwarf galaxy in the neighborhood.

With the help of citizen scientists, a team of astronomers has found an important new example of a very rare type of galaxy that may yield valuable insight on how galaxies developed in the early Universe.

Recently, the infrared Herschel Space Observatory, has taken a series of beautiful high-resolution infrared images of Andromeda. It is the first time we can see M31, at these wavelengths, at such a high resolution.

The two Magellanic Clouds (or Nubeculae Magellani), composed of the Large Megellanic Cloud and the Small Magellanic Cloud, are irregular dwarf galaxies visible in the southern hemisphere. They are members of our Local Group and orbit the Milky Way galaxy. Persian astronomer Al Sufi, in 964, was the first to have written anything about the Magellanic Clouds proving they have been known since early time amongst the Middle East peoples. Sufi, in his Book of Fixed Stars, calls the clouds...

The Local Group, compromising more than 30 galaxies (including dwarf galaxies and the Milky Way), is a group of galaxies with a gravitational center located somewhere between the Milky Way and the Andromeda Galaxy. With a binary (dumbbell) shape and a total mass of (1.29 ± 0.14) × 1012M the Local group covers a 10 million light-year diameter. The local group is part of the Virgo Supercluster. The two largest galaxies in the group are the Milky Way and the Andromeda both Spiral...

The IC 342/Maffei Group (also known as the IC 342 Group or the Maffei 1 Group) is the closest group of galaxies to the Local Group. The member galaxies are both concentrated around the two brightest galaxies of IC 342 and Maffei 1. The group can therefore be described as a binary group. Along with many others the group is located in the Virgo Supercluster.

Ring Galaxy -- A subclass of interacting galaxies, ring galaxies, provides a unique laboratory for studying unusually large bursts of non-nuclear star formation. The rings in these systems are often large (10s of kiloparsecs) and contain what appear to be associations of giant H{\small II} regions. As a basis for future modeling of star forming regions in observed ring galaxies we present a series of combined n-body/gas numerical experiments on ring formation and evolution. Three...

Irregular Galaxy -- In astronomy, a class of galaxy with little structure, which does not conform to any of the standard shapes in the Hubble classification. The two satellite galaxies of the Milky Way, the Magellanic Clouds, are both irregulars. Some galaxies previously classified as irregulars are now known to be normal galaxies distorted by tidal effects or undergoing bursts of star formation (see starburst galaxy). ----- NASA Click here to learn more on this topic from...

pawl
  • A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
The word 'pawl' probably comes from a Latin word meaning 'stake'.
