Thousands of galaxies in the process of making stars have been spotted by an international team of astronomers using ultra-sensitive radio images. Scientists compiled the images of the early universe using the International Low Frequency Array (LOFAR) telescope, a trans-European network of radio antennas. It works by combining the signals from more than 70,000 antenna, located in stations across the Netherlands and in partner European countries including the UK. By observing the same regions of sky repeatedly and combining the data to make a single very-long exposure image, the team detected...

Copy link for See 25,000 Supermassive Black Holes in One Map of the Sky At the center of almost every galaxy is a gigantic black hole — a place where gravity is so strong, not even light can escape its pull. Because black holes don't emit any light, we can't see them, but we can detect their presence by measuring radio signals emitted by the matter they eject. Now, an international team of astronomers has used those signals — with the help of supercomputers and an international telescope array — to create a map of 25,000 of these supermassive black holes.

LOFAR/LOL Survey Astronomers in Europe compiled the most detailed map of black holes to date. Their map of the northern sky shows 25,000 white dots, each representing a supermassive black hole.  The image above may look like a fairly normal picture of the night sky, but what you're looking at is a lot more special than just glittering stars. Each of those 25,000 white dots is an active supermassive black hole. And each of those black holes is devouring material at the heart of a galaxy millions of light-years away — that's how they could be pinpointed at all....

Astronomers used new algorithms to convert radio signals collected by a telescope into a vast map of supermassive black holes.

First possible radio signal emanating from an exoplanet about 51 light-years away, detected If confirmed through follow-up observations this radio detection opens up a new window on exoplanets and provides a novel way to examine alien worlds that are tens of light-years away. Dec 22, 2020 08:58:01 IST An international team of scientists has collected the first possible radio signal from a planet beyond our solar system, emanating from an exoplanet system about 51 light-years away. Using the Low-Frequency Array (LOFAR), a radio telescope in the Netherlands, the researchers uncovered emission b...
