Research Using the MMT in the News

From observations made using the MMT, Dr. E. Mamajek of the University of Rochester has discovered that the first known binary star is actually a sextuplet system.   To read the article published by Science Daily, press here.

The New Red Channel Detector

The installation and testing of a new detector for Red Channel has been completed by the UofA’s Imaging Technology Laboratory (ITL). The new device has 15-micron pixels and a format of 520 x 1032 pixels (spatial x dispersion). The read noise of the detector is 3.5 electrons. The measure QE for the detector is provided below. ITL’s web page ( provides additional details and information.

Countdown continues...

At 1.31am (MST) NASA will count down to T-3 hours mark for the centaur impact. We are busily working away making sure we have all our cameras aligned (we are using 4 different camera’s for different purposes tonight!), we are collecting calibration data that is vital for our science results, making sure our data reduction software works and staying in communication with NASA and all the other telescopes that are observing the event.

T-30 mins!

The last blog before impact (and probably for a while after the impact as I’ll be busy reducing the data we observe!)

Everything here is good – sky is clear with 0.5″ seeing! Could not have asked for a better night. We have moved back to the moon and setting up for the final time before impact.

A quick list of people you might have been watching on the webcam!

All Over!

LCROSS successfully impacted the moon at 4.31am (MST)!! NASA will be having a news conference at 7.00am (PDT) on NASA TV.

We collected data with multiple instruments throughout the impact and for an hour after it. We now have a multitude of data which needs careful reduction over the coming weeks until we will have the opportunity to make any statements on what we saw.

LCROSS: It all comes down to tonight...

After being involved in the LCROSS project and preparation for the ground based observations from the MMT over the last 18 months it has all come down to tonight. We have one shot at getting these observations so the nerves are running a little high in the control room!

In the last 10 minutes we have had confirmation from NASA that the centaur and payload (ie. the two halves of the rocket – the centaur will crash into the moon first with the payload carrying the instruments crashing in 4 minutes later) have separated successfully.

Watching LCROSS impact!

Want to see professional astronomers at work? We are taking the unique time of the LCROSS experiment to give you all a direct view into the world of a professional observatory for one night only!

We will be streaming images throughout the night which you can view at:
