Andromeda galaxy larger than thought

Filed under

The Andromeda galaxy just got bigger -- three times bigger, astronomers said on Monday.

The galaxy is not actually expanding. But new measurements suggest that the nearest galaxy to our own Milky Way is three times broader than astronomers had thought.

They now believe a thin sprinkling of stars once thought to be a halo is in fact part of Andromeda's main disk.

That makes the spiral galaxy, so close to Earth that it appeared as a fuzzy blob to the ancients, more than 220,000 light-years across -- triple the previous estimate of 70,000 to 80,000 light-years.

It appears that the outer fringes of the disk were made when smaller galaxies slammed together, they told a meeting of the American Astronomical Society in Minneapolis.

Andromeda is 2 million light-years from Earth. A light-year is the distance light travels in a year -- about 6 trillion miles.

Full Story.

  • KDE Plasma 5.5 Windows 8 Metro-Inspired Theme Looks Interesting
    KDE developer Kai Uwe has just published a lengthy article where he talks about developing a Windows 8-inspired theme for the upcoming KDE Plasma 5.5 desktop environment.
  • KDE Developer Working On Windows 8 Inspired Look
    Kai Uwe has been working on some experimental hacks to resemble Windows 8, although Microsoft's default interface has changed with Windows 10. He's calling this work "U-Bahn" (the German equivalent of a Metro subsystem system) in reference to Microsoft at the time calling it Metro. This was just some brief hacking and he's not planning to see this U-Bahn project through to the end.
  • Pursuing Awesomeness
    While applets can be installed through “Get Hot New Stuff” and distribution repositories, there’s also the classic .plasmoid file. A feature suggested by one of my colleagues – fresh KDE Plasma user – was to drag .plasmoid files onto the desktop or panel and have them installed. After Marco Martin implemented the neccessary KPackage plumbing this is now possible.
