This video illustrates the collision of two neutron stars (GW170817).

An international research collaboration, including four Northwestern University astronomers, is the first to detect the spectacular collision of two neutron stars in a nearby galaxy using both gravitational waves and light.

What is a neutron star? What is it like when two neutron stars collide? Northwestern University astronomers describe the GW170817 merger of these massive objects in our Universe.  

Following the October 16, 2017 announcement of the first-ever observation of a binary neutron star inspiral and merger, Northwestern’s astronomy research center, CIERA, held a discussion with the Northwestern scientists behind the discovery.

APERTURE: A Precise Extremely large Reflective Telescope Using Reconfigurable Elements. This is the deployment concept which was produced during the NIAC Phase I feasibility study. APERTURE is a UV-Visible telescope with a 16-m diameter primary mirror. The primary is a flexible membrane coated with magnetic smart material. The shape of the reflector can be corrected
