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!

Recently added Dataset 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. Astronomy News This Video Game Lets You Explore Mars’ Actual Surface Alan Chan grew up thinking humans would be living in space and exploring Mars by now. Unfortunately, that&rsquo;s not the case. Instead, he decided to explore space on his own by creating a video game that allows people to drive around the Red Planet&rsquo;s actual terrain in a souped-up rover. &ldquo;Red Rover,&rdquo; a new video game, recreates Mars&rsquo; surface using satellite and terrain data from NASA&rsquo;s HiRISE Mars orbiter.

The man revolutionized physics when he was in his 20s and 30s. He came up with a whole new way of understanding reality, not as a fixed grid against which events occur, but as fundamentally intertwined with time and perception. Trying to prove Einstein wrong, somehow, is a perennial goal of budding and experienced physicists alike. Well, they&rsquo;ll have to keep trying.
