Astronomers have used two Australian radio telescopes and several optical telescopes
to observe a nearby radio galaxy, known as Centaurus A, and to study complex mechanisms that are fuelling jets of material blasting away from a black hole 55 million times more massive than the sun.

int/gaia/) Gaia makes observations using optical telescopes
in space, the data from the radio telescopes was used for very long baseline interferometry (VLBI) - a technique that uses multiple radio telescopes to act as one giant telescope.
, when pointed at distant objects, make things appear closer, larger or brighter to our eyes.
National Science Foundation announced plans to divest from two radio telescopes, the Green Bank Telescope and the Very Long Baseline Array, as well as three optical telescopes
at Kitt Peak National Observatory.
The measurement is some 50 times more precise than those provided by groundbased optical telescopes
, Space Daily reported.
While this asteroid would appear as no more than a point of light to optical telescopes
, using radar we're able to discern the physical characteristics of the asteroid and we're able to measure its exact distance from Earth.
While radio and optical telescopes
can resolve and monitor the individual blazar images, Fermi's LAT cannot.
The SKA will use a forest of antennae, spread across remote terrain, to pick up radio signals from cosmic phenomena that cannot be detected by optical telescopes
Astronomers are using radar and optical telescopes
to get a better fix on the asteroid's location, its unusual spin and the flight path in hopes of refining estimates on where it will travel in the future.
Collecting at least 12 times more light than the current largest optical telescopes
, it will push forward our understanding of planets beyond our solar system, including those where life might exist.
Looking at the positions of these bright objects with optical telescopes
on the Earth, they found galaxies that would not normally be bright at the far-infrared wavelengths observed by Herschel.
