Over the years, more and
more radio astronomers were joining the astronomy department at the University of Toronto, and in the 1960's, the David Dunlap Observatory actively participated in the development of the Algonquin Radio Observatory in Ontario.
The more radio astronomers learn about fast radio bursts (FRBs), the more confused they get.

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.
Radio astronomers have used a similar approach for many years, with great success, but light waves are more than a million times smaller than radio waves, meaning optical interferometry requires a million times greater accu

astronomers to point other telescopes their way, boosting the chances of learning
more about them via x-rays, gamma - rays,
radio waves, neutrinos and
more.

astronomers since they were first detected nearly 10 years ago has finally been tied to a source: an older dwarf galaxy
more than 3 billion light years from Earth.
«What we're seeing is a star that is the cosmic equivalent of «Dr. Jekyll and Mr. Hyde,» with the ability to change from one form to its
more intense counterpart with startling speed,» said Scott Ransom, an
astronomer at the National
Radio Astronomy Observatory (NRAO) in Charlottesville, Va. «Though we have known that X-ray binaries — some of which are observed as X-ray pulsars — can evolve over millions of years to become rapidly spinning radio pulsars, we were surprised to find one that seemed to swing so quickly between the two.&r

Staring at a small patch of sky for
more than 50 hours with the ultra-sensitive Karl G. Jansky Very Large Array (VLA),
astronomers have for the first time identified discrete sources that account for nearly all the
radio waves coming from distant galaxies.
Following the announcement, every
radio astronomer who had access to the right equipment was observing the known pulsars and searching for

«Observations with the next generation of
radio telescopes will tell us more about what actually happens when a star is eaten by a black hole — and how powerful jets form and evolve right next to black holes,» explains Stefanie Komossa, astronomer at the Max Planck Institute for Radio Astronomy in Bonn, Ger

That explains why
radio astronomers have found
more complex molecules in the warmer,
more active star - birthing regions of dust clouds than in the colder, darker areas.
Since Lew Snyder and David Buhl discovered interstellar formaldehyde in 1969,
astronomers have identified
more than 150 molecules in deep space, mostly by using
radio telescopes to detect the faint radiation the molecules emit.
Funding for astronomy is far
more limited than that available for cancer research, say, and compared with most other fields of science, the number of professional
astronomers is astonishingly small (the membership of the American Astronomical Society would just about fit into
Radio City Music Hall).
Astronomers using the super-sharp
radio vision of the National Science Foundation's Very Long Baseline Array (VLBA) have found the shredded remains of a galaxy that passed through a larger galaxy, leaving only the smaller galaxy's nearly - naked supermassive black hole to emerge and speed away at
more than 2,000 miles per second.
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.

more - massive components, presumed to be a compact double star.
Infrared light, as well as X-rays and
radio,
