Title: The Ring Nebula Around the Blue Supergiant SBW1: Pre-Explosion Snapshot of a SN 1987A Twin Authors: Nathan Smith, W. David Arnett, John Bally, Adam Ginsburg, Alexei V. Filippenko SBW1 is a B supergiant surrounded by a ring nebula that is a nearby twin of SN 1987A. We present images and spectra...
Title: Alfvén Reflection and Reverberation in the Solar Atmosphere Authors: P. S. Cally Magneto-atmospheres with Alfvén speed [a] that increases monotonically with height are often used to model the solar atmosphere, at least out to several solar radii. A common example involves uniform verti...

13,350 years ago the glacial Lake Iroquois broke out from behind the Adirondack Mountains and the northern ice sheet.
It was three times the size of modern Lake Ontario.
As the natural ice dam collapsed, floodwaters rushed down the Hudson River Valley; past modern Manhattan, Brooklyn, and Sta...
