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.
