What is Universe3D.org?

The intention of Universe3D.org is to host links to web content that enable the enhancement of our three-dimensional view of the Universe. Feel free to join in and edit--Wikipedia-style!

Methanol MultiBeam Survey The Methanol MultiBeam Survey is a sensitive survey of massive young stars in the Milky Way Galaxy to detect methanol masers. The survey is carried out by scanning the telescope in galactic longitude. Spectra cover a 4-MHz band, corresponding to a velocity range of 180 km/s, with 2048 channels each separated by 0.09 km/s. Regions towards the galactic centre are scanned more than once with different velocity settings, so that all likely radial velocities are searched. A second frequency band centred on the 6035-MHz line of hydroxyl (OH) is observed in parallel with the methanol band.

Origami-inspired design may soon help cushion rocket landings
Whether applied to auto collisions or rocket landings, absorbing energy from impacts is a valuable trait, and industries have been working on various solutions for years. For spacecraft, landing safely has entailed everything from inflatable airbag systems to sky cranes to retro-thrusters. But what if the force of impact never made it to the spacecraft at all?

That&rsquo;s the idea being pursued by Hiromi Yasuda and colleagues at the University of Washington. They&rsquo;re using foldable materia
