Planetary nebula lasers

Astronomical masers (the radio wavelength analogs of lasers) were first identified in space over fifty years ago and have since been seen in many locations; astronomical lasers have since been seen as well. Some of the most ...

Extending maser techniques to Floquet systems

A team of researchers affiliated with several institutions in China and one in Germany has investigated the possibility of extending maser techniques to Floquet systems. In their paper published in the journal Science Advances, ...

Masers in stellar nurseries

(Phys.org)—Astronomers have come to realize that the process of star formation, once thought to consist essentially of just the simple coalescence of material by gravity, occurs in a complex series of stages. As the gas ...

Image: Hubble peers at the heart of NGC 5793

(Phys.org) —This new Hubble image is centered on NGC 5793, a spiral galaxy over 150 million light-years away in the constellation of Libra. This galaxy has two particularly striking features: a beautiful dust lane and an ...

Heat wave signals the growth of a stellar embryo

An international research team with the Max Planck Institute for Astronomy (MPIA) participating has detected a propagating heat wave near a massive protostar. It confirms the scenario that such objects grow in bursts. This ...

Most distant detection of water in the Universe

(PhysOrg.com) -- Astronomers have found the most distant signs of water in the Universe to date. Dr John McKean of the Netherlands Institute for Radio Astronomy (ASTRON) will be presenting the discovery at the European Week ...

Hydrogen masers reveal new secrets of a massive star

While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star's ...
