Vibrant Gaseous Ribbons: The Veil Supernova Remnant

This 3-D visualization flies across a small portion of the Veil Nebula as photographed by the Hubble Space Telescope. This region is a small part of a huge expanding remnant from a star that exploded many thousands of years ago. Hubble resolves tangled rope-like filaments of glowing gases. They have been shocked and heated by colliding with cooler, denser interstellar gas. ... Read More إقرأ المزيد | Share it now!

Behind the Webb: Strong and Steady (Episode 28)

Because the Webb Telescope will be launched into space and operate in an extremely cold environment, it needs to be built with materials that are both lightweight and stable. It needs to maintain its shape despite a range of temperatures. One of the science instruments on the telescope, NIRSPEC, or Near Infrared Spectrograph, is largely made from a ceramic known as silicon carbide. This episode of Behind the Webb takes us on a journey from the origins of this special material to how it’s incorporated into the next great space observatory.... Read More إقرأ المزيد | Share it now!
