Latest Very Large Array Stories
Catching the formation of a single star is a tough thing to do, and yet a large team of international astronomers has announced the discovery of four stars all forming in the same system.
Enormous young stars, which have over 10 times the mass of the Sun, shine brilliantly in ultraviolet wavelengths, energizing the gas around them, and it has long been a mystery why this superheated gas doesn't explode outwards.
Astronomers using the Very Large Array (VLA) have made a discovery that helps explain how double-star systems form.
The edge-on spiral galaxy UGC 10288 appeared to be a single object in previous observations. However, new detailed radio data revealed that the large perpendicular extension of UGC 10288's halo is really a distant background galaxy with radio jets.
As the government shutdown now enters its second week, redOrbit.com takes a look at 5 ways it's affecting the world of science.
For the first time, astronomers have identified discrete sources that account for nearly all of the radio waves coming from distant galaxies.
Astronomers say they have discovered a star factory in a galaxy so distant that they see it when the Universe was only six percent of its current age of about 13.7 billion years old.
The world was on edge earlier this month when North Korea detonated an underground nuclear explosion meant to showcase to the world community the abilities of this beleaguered nation.
On February 15, astronomers will have an exciting opportunity with a record-setting close approach of an asteroid. The research team, using the National Radio Astronomy Observatory (NRAO) and NASA telescopes, will gain a key clue that will help predict the future of this nearby cosmic neighbor.
It has taken more than a decade of design and construction, but North America has finally delivered the last of 25 antenna dishes, marking an important milestone in the construction of an observatory astronomers are using to open up a "final frontier" of the spectrum of visible light to exploration.
Very Large Array -- The Very Large Array, one of the world's premier astronomical radio observatories, consists of 27 radio antennas in a Y-shaped configuration on the Plains of San Agustin fifty miles west of Socorro, New Mexico. Each antenna is 25 meters (82 feet) in diameter. The data from the antennas is combined electronically to give the resolution of an antenna 36km (22 miles) across, with the sensitivity of a dish 130 meters (422 feet) in diameter. The VLA is an...
Radio Telescope -- In contrast to an ordinary telescope, which produces visible light images, a radio telescope "sees" radio waves emitted by radio sources located anywhere in the Universe, typically by means of a large parabolic ("dish") antenna, or arrays of them. The best-known (and largest) radio telescope is in Arecibo, Puerto Rico. A well-known radio telescope being an array of antennae is the Very Large Array (VLA) in Socorro, New Mexico. The largest (100-meter diameter) and most...
