Crab Nebula Pulsar captured- see the videos!

In January 1969, astronomers at Steward Observatory were the first to detect the optical flash from a pulsar, observing the Crab pulsar with a photon-counting detector. In January 2019, near the 50th anniversary of this discovery, Steward astronomers, testing a new high-speed imaging camera at the MMT, observed the Crab pulsar, taking images 194 times per second. This video shows the flash in visible light of the Crab Nebula pulsar, a rapidly rotating neutron star that is the collapsed remnant of a supernova. This video shows the pulsar additionally processed.

UPDATE Km 18.5 Road Stabilization Project

Phase II of the road stabilization project is underway with major interruptions. Heavy machinery is being used while they repair and pour concrete on the road. All vehicular traffic is unable to cross until further notice. Coordination with staff is required prior to going up the mountain. If you are an observer, please contact Susan Wahl to make special arrangements during the road construction.

Aging a Flock of Stars in the Wild Duck Cluster

Do star clusters harbor many generations of stars or just one? Scientists have long searched for an answer and, thanks to the MMT and its Hectochelle instrument, found one in the Wild Duck Cluster, where stars spin at different speeds, disguising their common age. The UA news story can be read here.
