we've lumpy outer arms

Finally got 'round to reading the Space dot com article by Canadian science writer Elizabeth Howell entitled The Milky Way's outer reaches may have lumpy, choppy arms.

Howell reports that new data from the Hubble Space Telescope shows that the outer arms of our Milky Way galaxy may be clumpier and stubbier than originally believed. By measuring the dust signatures in the Perseus arm, scientists feel the outer edges of the galaxy might not be long, smooth, and graceful but rather shorter and chopped up.

The future Roman Space Telescope, which will study the entire plane of the galaxy, is expected to corroborate these findings.

The piece was published in January this year.


A word of warning: the Space dot com web site is laden with many, many ads that can make for a very annoying and distracting experience and can overload your browser and slow your device.
