A massive and rare merging of two galaxies has been spotted in images taken by the Herschel space observatory, a European Space Agency mission with important NASA participation.The findings help explain a mystery in astronomy: whether elliptical galaxies built up slowly over time through the acquisitions of smaller galaxies, or formed more rapidly through powerful collisions between two large galaxies.
This is a great post Eric. I am glad you are back on the blog.
