Historical Photo of the MMTO

In 1981, a photograph was taken of the sun rising behind the original MMTO from a small telescope located on Kitt Peak, nearly 47 miles away. Read the interesting background regarding the photo, which now hangs in the newly furnished and upgraded MMTO control room.

Margaret J. Geller Receives Award

Dr. Margaret J. Geller, Harvard/CfA astrophysicist, was recently awarded this year's Karl Schwarzschild Medal of the German Astronomical Society. This prestigious award honors outstanding achievements of fundamental importance in astronomical research. Dr. Geller has been a frequent user of the MMTO. Read more.

Art Piece Inspired by the MMTO

For a very interesting and intriguing perspective, take a look at some large scale assemblages by artist John Zaklikowski.  He uses computer and electronic parts, as well as more common objects to produce his artwork, described by him as a "testament to and commentary on the intersection of art, science, and technology." Look closely at "Ghent" and you might recognize the 6 mirrors of the original MMTO.

HSRED Version 2.0 Released

We are pleased to release version 2.0 of HSRED, a reduction package for Hectospec data. This update incorporates a number of significant improvements provided by the Telescope Data Center at SAO.  Key changes include new support for the 600-line grating, fine-tuning the wavelength calibration, improved cosmic ray rejection and sky subtraction, support for offset sky observations, a model correction for the red light leak present in Hectospec data, and automatic correction for the A- and B-band telluric lines.

Variability Discovered in Star System

Arizona astronomers have used the MMT's adaptive optics system and the ARIES instrument to discover significant changes in the appearance of the variable binary star system UY Aurigae since 1994. The new spectrum is only the second ever published for one of the stars. The changes in brightness indicate increased interaction between the stars and their circumstellar disks. More information can be found here.

Final August - December Observing Schedule

The final observing schedule for August - December has been posted along with Program Titles.

Fire Restrictions Lifted - July 11

Distant Milky Way M Giants

Scientists using the MMT's Red Channel Spectrograph have discovered the most distant Milky Way stars known to date. The red giant stars lie almost a third of the way to the Andromeda Galaxy. Read more.

A New Discovery

Researchers using the MMT's Blue Channel Spectrograph have discovered a pair of white dwarfs circling one another at high speed, taking only 20 minutes to complete one orbit. Only eight other similar pairs are currently known. The new discovery is a fast one, with the orbital period the second-quickest of those already found. The two white dwarfs are about one-third and one-tenth the mass of the Sun and are expected to merge completely in less than 9 million years, slowly losing their angular momentum through gravitational wave radiation.

Mt. Hopkins Road - Open

Starting on June 25, the Mt. Hopkins Road will be open as normal until further notice. The currently scheduled roadwork has been completed. The next phase of work will resume later in the summer.
