Last week at the American Astronomical Society's meeting, astronomers announced the detection of a second type of radio static from the heavens, and although it may not come from an era quite as ancient as TV snow does, it may probe the period immediately afterward — an equally mysterious time when the first stars and black holes were lighting up.

Penn State University astronomers have discovered that the mysterious «cosmic whistles» known as fast radio bursts can pack a serious punch, in some cases releasing a billion times more energy in gamma - rays than they do in radio waves and rivaling the stellar cataclysms known as supernovae in their explosive power.

SAN JOSE, California — They don't hold out much hope that Vulcans will arrive on our doorsteps intoning «live long and prosper,» but many astronomers believe that making radio contact with an alien civilization would fundamentally alter humanity for the better.

True, astronomers still don't know the origins of these extragalactic milliseconds - long radio pulses, and until this year fewer than 20 had ever been detected.

SIX years ago, radio astronomers discovered an area of about a million square kilometres on the equator of Mars that does not reflect radar signals.

Astronomers also discovered weak, long - lasting radio emissions coming from within 130 light - years of FRB 121102, suggesting the two are related — though we don't know how, if at all.

Radio astronomers have yet to identify anything as complex as an amino acid, so astrochemists do not know exactly how complex these gaseous molecules can get.

And this allows them to do something new: to tell their astronomer colleagues roughly where to look in the sky, using ordinary telescopes, for some form of electromagnetic waves (perhaps visible light, gamma rays, or radio waves) that might have been produced by whatever created the gravitational waves.

«Many astronomers are surprised at this discovery, because they didn't expect such strong radio emission from this object,» said Shri Kulkarni, a Caltech professor who was on the team that first discovered a brown dwarf in 1995, and advisor to one of the students.

The astronomers began their quest by using the VLBA to make very high resolution images of more than 1,200 galaxies, previously identified by large - scale sky surveys done with infrared and radio telescopes.

«By doing this survey and making the results available, we are bringing low - frequency radio data, previously quite difficult to produce, to all astronomers in a simple and easy manner,» Perley said.

«Amazingly, even though the sky is known to be full of transient objects emitting at X - and gamma - ray wavelengths,» NRL astronomer Dr. Joseph Lazio pointed out, «very little has been done to look for radio bursts, which are often easier for astronomical objects to produce.»

March 19 - 23, 2018, at Lorenz Center in Leiden, this workshop brings together experts and interested radio astronomers to learn how to produce high resolution images with the Low Frequency Array (LOFAR) and to discuss and finalize the details for implementing a pipeline to do this on a large scale to post-process already existing observations.

The idea had been kicking around since the 1920s, when Georges Lemaitre, a Belgian priest - scholar, first tentatively proposed it, but it didn't really become an active notion in cosmology until the mid-1960s when two young radio astronomers made an extraordinary and inadvertent discovery.
