Researchers Take A New Look At Masers

Michael Harper for redOrbit.com — Your Universe Online While we´ve been fixated with lasers – shooting them from flying ships, attaching them to shark´s heads, what have you – there´s been another sort of beam waiting in the wings for someone to take notice. In fact, "Masers" have been around before their cooler, younger sibling the Laser. They´ve also been more difficult to generate, requiring high magnetic fields and plenty of cooling. Masers are...

The discovery of water in the early Universe was possible only due to the chance alignment of a foreground galaxy and the distant quasar MG J0414+0534. The foreground galaxy acts like a cosmic telescope, magnifying and distorting the light from the quasar forming four distinct images of the quasar. Without this gravitational lensing effect, 580 days of continuous observations with the 100 m telescope would have been needed instead of the 14 hours used to make this remarkable discovery....

Two of the World's Largest Interferometric Facilities Team-up to Study a Red Giant Star Using ESO's VLTI on Cerro Paranal and the VLBA facility operated by NRAO, an international team of astronomers has made what is arguably the most detailed study of the environment of a pulsating red giant star. They performed, for the first time, a series of coordinated observations of three separate layers within the star's tenuous outer envelope: the molecular shell, the dust shell, and the maser shell,...

Astronomers based at Jodrell Bank Observatory have discovered a giant bridge of methyl alcohol, spanning approximately 288 billion miles, wrapped around a stellar nursery.  The gas cloud could help our understanding of how the most massive stars in our galaxy are formed. The new observations were taken with the UK's MERLIN radio telescopes, which have recently been upgraded.  The team studied an area called W3(OH), a region in our galaxy where stars are being formed by the...

Radio Astronomy -- Radio astronomy is the study of celestial phenomena through measurement of the characteristics of radio waves emitted by physical processes occurring in space. Radio waves are much longer than light waves. In order to receive good signals, radio astronomy requires large antennas. Radio astronomy is a relatively new field of astronomical research. The earliest investigations into extraterrestrial sources of radio waves were by Karl Guthe Jansky, an engineer with Bell...
