Ten years of Very Large Telescope adaptive optics

(PhysOrg.com) -- Ten years ago today, NACO became operational: the first adaptive optics system of ESO's Very Large Telescope (VLT). Adaptive Optics allows astronomers to remove the stars' twinkling – disturbances due ...

A strong magnetic field around the Milky Way's black hole

(Phys.org) —Astronomers have made an important measurement of the magnetic field emanating from a swirling disk of material surrounding the black hole at the center of our Milky Way Galaxy. The measurement, made by observing ...

4C+29.30: Black hole powered jets plow into galaxy

(Phys.org) —This composite image of a galaxy illustrates how the intense gravity of a supermassive black hole can be tapped to generate immense power. The image contains X-ray data from NASA's Chandra X-ray Observatory ...

Writing the history of the 'Cosmic Dark Ages'

For millions of years after the Big Bang, there were no stars, or even galaxies to contain stars. During these "Cosmic Dark Ages," neutral hydrogen gas dominated the universe. When clouds of primordial hydrogen gas started ...

A multi-wavelength view of radio galaxy Hercules A

(Phys.org)—Spectacular jets powered by the gravitational energy of a super massive black hole in the core of the elliptical galaxy Hercules A illustrate the combined imaging power of two of astronomy's cutting-edge tools, ...

How to rediscover life on Earth by looking at the Moon

(PhysOrg.com) -- By observing the Moon using ESO's Very Large Telescope, astronomers have found evidence of life in the universe -- on Earth. Finding life on our home planet may sound like a trivial observation, but the novel ...
