Andromeda galaxy larger than thought

Filed under
Sci/Tech

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.

FSF's High Priority Project List Now Has A Committee

The Free Software Foundation has now built up a committee to review their "High Priority Projects" list and they're looking for more feedback from the community. Nearly ten years ago is when the Free Software Foundation began listing what they viewed as the High Priority Free Software Projects in a list. This list has over time contained some definite high-priority projects related to freeing Java and Adobe PDF support and open graphics drivers to some more obscure projects of high priority like a free version of Oracle Forms, a replacement to OpenDWG libraries for CAD files, automatic transcription software, etc. I've personally called out many of the FSF HPP for what they're worth with my thoughts over the years.
