An international team of astronomers has discovered one of the largest features ever observed in the center of the Milky Way – a pair of enormous radio-emitting bubbles that tower hundreds of light-years above and below the central region of our galaxy.
Atacama Large Millimeter/submillimeter Array
The Atacama Large Millimeter/submillimeter Array in the Atacama Desert, Chile, is the most complex observatory ever built.
Very Long Baseline Array
The Very Long Baseline Array (VLBA) is ten radio telescopes stationed across 5,351 miles. It’s the world’s sharpest, dedicated telescope array.
Standing at the high site of the Atacama Large Millimeter/submillimeter Array is like standing on another world. Sandy gravel…

A Comet Hits JupiterThis pair of radio images taken by the Very Large Array (VLA) shows the planet Jupiter before (left - June 24, 1994) and after (right July 19, 1994) fragments of the comet Shoemaker-Levy 9 struck the planet in 1994. The disk of the planet is in the center of the images. The bright red spots are regions high above Jupiter's "surface" where electrons interacting with the planet's intense magnetic field are producing strong radio emission. These "radiation belts" are similar to the Van Allen Radiation Belts discovered above the Earth in 1958.

Chilean Senate Distinguishes ALMA For 1st Image of Black Hole
The Senate of Chile recognized ALMA for its role in obtaining the first image of a black hole as part of the Event Horizon Telescope.
Neither a hole nor really black, a stellar black hole is actually the superdense remains of a very big star that imploded, violently collapsing in on itself, during a supernova.
We aim radio telescopes at the Sun, planets, moons, and planetesimals in our Solar System.
