MMIRS settles into new home at the MMT

MMIRS (MMT and Magellan Infrared Spectrograph) has just completed its first successful week of commissioning at the MMT. The team took imaging data, longslit spectra, multi-object slit mask spectra all with control from MMIRS of the telescope guiding and wavefront sensing. 

Congratulations to the team – we look forward to the next run in a couple of weeks time. 

Below is a YHK image of Messier 64, the Black Eye Galaxy.

MMTO Confirms Ultra-faint Object in Milky Way Halo is Dwarf Galaxy.

How small can a galaxy be?

Astronomers are now finding small-fry galaxies that contain fewer than a million, possibly as few as a thousand, stars.

Until recently, these very faint, dwarf galaxies in the halo of the Milky Way have eluded discovery.  

Read about this exciting new result by a team including Ed Olszewski, Jill Bechtold & Tim Pickering at UA News.org.
