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 Uranus Smells Exactly How You Think It Does Scientists confirm that Uranus’ atmosphere contains hydrogen sulfide, a compound long suspected to be swirling about in the planet’s clouds. Using the Gemini North telescope in Hawaii, researchers from the United Kingdom analyzed Uranus using a technique known as spectroscopy to identify the elements contained within. They relied on the Near-Infrared Integral Field Spectrometer (NIFS) at Gemini for the task, which involves breaking down the light reflected from Uranus by wavelength Tue, 24 Apr 2018 10:00:00 GMT Creating Star Stuff on Earth is the Aim of New $7 Million Project Astrophysicists will conduct experiments designed to re-create the physical environment inside stars, with a new $7 million grant that the Department of Energy’s National Nuclear Security Administration (DOE/NNSA) has awarded to The University of Texas at Austin. This work could help astronomers reduce uncertainties about the sizes and ages of super-dense objects known as white dwarf stars. The DOE/NNSA grant, distributed over a five-year period, will allow the university to establish a n Tue, 24 Apr 2018 10:00:00 GMT City of Light hosts inaugural International Day of Light PARIS.
