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.

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
