A new survey of our home galaxy, the Milky Way, combines the capabilities of the Very Large Array and the Effelsberg telescope in Germany to provide astronomers with valuable new insights into how stars much more massive than the Sun are formed.

A highly-detailed VLA image indicates that the jets of material propelled outward by young stars much more massive than the Sun may be very different from those ejected by less-massive young stars.

New, high-resolution VLA images of a giant molecular cloud where new stars are being born show changes since a set of observations made more than two decades ago. Tracking changes in this region over time can reveal new details about the process of star formation and the interactions of outflows from young stars.

The Very Large Array can’t image a big section of sky all at once. Instead, it must scan the sky over time. The VLA Sky Survey is using this method to create a map of nearly 80% of the observable sky. Join our host Summer Ash of the National Radio Astronomy Observatory as she talks about how the VLA is taking the time to see the big picture of the radio sky.

New multi-wavelength observations mounted by the Event Horizon Telescope (EHT) collaboration across the entire electromagnetic spectrum have provided new insight into the impact of the black hole at the core of galaxy M87 on its immediate, and not so immediate, surroundings.

Astronomers using the VLA and VLBA have found the most distant cosmic jet yet discovered, material propelled at nearly the speed of light by a supermassive black hole in the core of a galaxy some 13 billion light-years from Earth.

When the Very Large Array was completed forty years ago, it was a different kind of radio telescope. Rather…

VLA Sky Survey Reveals Newborn Jets in Distant Galaxies
VLA Sky Survey Reveals Newborn Jets in Distant Galaxies
November 19, 2020 at 10:00 am | News Release

Comparing data from VLA sky surveys made some two decades apart revealed that the black hole-powered “engines” at the cores of some distant galaxies have launched new, superfast jets of material during the interval between the surveys.
