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.

A weird, orbital dance keeps these moons of Neptune from hitting each other
Bobbing up and down like a carousel horse might not sound like a stable way to orbit a planet, but it works for one little moon of Neptune. The planet's innermost known satellite, Naiad, has a tilted orbit and it moves up-and-down relative to its neighboring moon, Thalassa.

The strange arrangement keeps the two moons from hitting each other or being thrown off into space, despite having close orbits, according to a new study. The finding also helps reveal some of the history behind Neptune&rsqu
