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.

Fri, 18 Jan 2019 12:00:00 GMT The plants that China sprouted on the Moon have died Dead plants Earlier this month, an experiment on China&rsquo;s Chang&rsquo;e 4 lander got cotton plants to sprout on the Moon, a historic first. Well, they&rsquo;re already dead. On Jan. 7, China&rsquo;s space agency released pictures of cotton seeds beginning to grow on the Chang&rsquo;e 4 lander. But, as reported by GBTimes on Jan. 16, the new sprouts haven&rsquo;t survived the freezing temperatures on the lunar surface, even in their protective capsule. The cotton seeds sprouted inside of a c Fri, 18 Jan 2019 12:00:00 GMT News Cosmography of the Local Universe View a film by Hélène Courtois, Daniel Pomarède, R.
