A composite radio-optical image shows five new clouds of hydrogen gas discovered using the National Science Foundation’s Green Bank Telescope.
New VLA Images Unlocking Galactic Mysteries
Astronomers have produced a scientific gold mine of detailed, high-quality images of nearby galaxies that is yielding important new insights into many aspects of galaxies, including their complex structures, how they form stars, the motions of gas in the galaxies, the relationship of normal matter to unseen dark matter, and many others.
VLBA Yields Rich Scientific Payoffs
Having the sharpest pictures always is a big advantage, and a sophisticated radio-astronomy technique using continent-wide and even intercontinental arrays of telescopes is yielding extremely valuable scientific results in a wide range of specialties. That’s the message delivered to the American Astronomical Society’s meeting in Austin, Texas, by Mark Reid of the Harvard-Smithsonian Center for Astrophysics, a leading researcher in the field of ultra-precise astronomical position measurements.
VLBA Movies Reveal New Details of Cosmic Jets
Astronomers have known for decades that supermassive black holes at the cores of galaxies can shoot out jets of subatomic particles at tremendous speeds.
New View of Distant Galaxy Reveals Furious Star Formation
A furious rate of star formation discovered in a distant galaxy shows that galaxies in the early Universe developed either much faster or in a different way from what astronomers have thought.
VLBA Changes Picture of Famous Star-Forming Region
Using the supersharp radio vision of the National Science Foundation’s Very Long Baseline Array, astronomers have made the most precise measurement ever of the distance to a famous star-forming region.
