New Milky Way Tidal Stream in Triangulum
"Stellar streams are found throughout the outer region of the Milky Way. They are presumed to originate from disrupting dwarf galaxies or globular clusters. We have discovered a new stellar stream in the Milky Way using the Sloan Digital sky survey 3 all-sky imaging, which we call the Triangulum Stream. Kinematic studies of this and similar strams will provid tight constraints on the strenght, shape and lumpiness of the Galacitc gravitation potential."

11.14.2013 Hubble Reveals First Pictures of Milky Way's Formative Years
"For the first time, we have direct images of what the Milky Way looked like in the past," said study co-leader Pieter G. van Dokkum of Yale University in New Haven, Conn. "Of course, we can't see the Milky Way itself in the past. We selected galaxies billions of light-years away that will evolve into galaxies like the Milky Way. By tracing the Milky Way's siblings, we find that our galaxy built up 90 percent of its stars between 11 billion and 7 billion years ago, which is something that has not been measured directly before."

10.23.2013 Astrophysics advance explanation for star formation
"After decades of inconclusive debate about the interpretation of the correlations among molecular cloud properties that I published in 1981, it's gratifying to see that my original idea that they reflect a hierarchy of supersonic turbulent motions is well supported by these detailed new simulations showing that the debated complicating effects of gravity, magnetic fields, and multiphase structure do not fundamentally alter the basic picture of a turbulent cascade," said Larson in response to the new findings by the UC San Diego researcher.

Public Events | VIEW ALL
The Leitner Family Observatory and Planetarium is open every Tuesday night for a planetarium show. Weather permitting there will also be public viewing of planets, nebulae, star clusters and whatever happens to be interesting in the sky. Seats are available on a first come first serve basis. No reservations necessary.
