Astronomers capture some of the most detailed images ever seen of galaxies in deep space 🌌
A supermassive black hole at the centre of a galaxy, seen faintly in the centre, shoots out jets of material across spaceThey are in much higher definition than normal and reveal the inner workings of galaxies in unprecedented detail.The researchers say that the pictures will transform our understanding of how galaxies evolve.
What is new is that the team has dramatically improved the resolution of radio images by linking together more than 70,000 small antennae spread across nine European counties.The radio signals have been captured by 70,000 one-metre-high antennas across nine European countries "To work on the data for so long, and then to finally get such images and be able be the first person to see what it looks like is just incredible," she told BBC News.
The jets are caused by a supermassive black hole at the heart of the galaxy- an object with such strong gravity not even light can escape. It normally sucks in material - but the inward pull also creates forces around the black hole that result in material being spat out, far into space. "These high-resolution images allow us to zoom in to see what's really going on when supermassive black holes launch these jets of material."The picture on the left is of a galaxy observed in visible light. The middle image shows the same galaxy but seen at radio frequencies and on the right is the high-definition image.
The first set of results have led to the publication of nine scientific papers on the dynamics of black holes in galaxies. But this is just the start for the team. They plan to scan millions of galaxies over the next few years.
