The images capture drama billions of years ago in the early Universe -- glinting galaxies, glowing with stars that have exploded into supernovas

The images capture drama billions of years ago in the early Universe—glinting galaxies, glowing with stars that have exploded into supernovas and blazing jets fired from black holes.

An international team of astronomers has published the most sensitive images of the Universe ever taken at low radio frequencies, using the International Low Frequency Array (LOFAR).

An international team of astronomers has published the most sensitive images of the Universe ever taken at low radio frequencies. The images were taken using the International Low Frequency Array (Lofar). The software needed to do this, specifically that which handles the direction-dependent effects that would otherwise contaminate the images, goes back to the work of a former Rhodes University Postdoc Dr Cyril…

Astronomers used supercomputers and an international network of antennas to create a map of 25,000 supermassive black holes.

A 21st-century 'mega-science' project called the Square Kilometer Array just opened for business, but how does it work? And what is 'radio astronomy?'

By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Boötes. The signal could be the first radio emission collected from a planet beyond our solar system.

ASTRONOMERS have for the first time discovered an extraordinary type of dwarf planet, dubbed a 'super-planet'.

There are more to come.

By monitoring the cosmos with a radio telescope array, a Cornell University-led international team of scientists has detected radio bursts emanating from the constellation Boötes. The signal could be the first radio emission collected from a planet beyond our solar system.

An international team of researchers led by Leiden University (the Netherlands) has mapped nine gigantic collisions of galaxy clusters. The collisions took place seven billion years ago and could be observed because they accelerate particles to high speeds. It is the first time that collisions of such distant clusters have been studied. The researchers publish their findings in the journal Nature Astronomy on…

Abell 2255 is an actively-merging cluster of galaxies, and the merger is marked by mayhem. New LOFAR images reveal more details of the chaos.
