A cataclysmic collision between two galaxies could leave the supermassive black hole at the centre of the larger one ‘starved of material’, astronomers claim. Experts from the University of Tokyo created the ‘most accurate simulation’ of a range of scenarios to understand what happens when galaxies merge. It was previously thought that collisions between galaxies … Read more
Nasa finds there are far fewer galaxies than first thought, with numbers in the billions rather than trillions Previous estimates suggestsed there were around two trillion galaxies But new data from Nasa’s New Horizons spacecraft suggests this isn’t the case Instead, Nasa now estimates that there are hundreds of billions of galaxies By Shivali Best … Read more

NASA’s Hubble telescope spots the ‘Greater Pumpkin’ galaxies 120 MILLION light-years from Earth, complete with glowing eyes and a carved crooked smile NASA’s Hubble telescope captured a spooky scene 120 million light-years away Deemed the ‘Greater Pumpkin’, the image is of two galaxies colliding The aging red stars are creating an orange hue that resembles … Read more
NASA and ESA find evidence that the first stars and galaxies formed much earlier than researchers thought, beyond the reach of the Hubble Space Telescope Hubble can see the universe back to within 500 million years of the Big Bang Experts used the telescope to determine the age of the first stars and galaxies The … Read more
After a thirty-year search, the missing ordinary — or ‘baryonic’ — matter that scientists predicted ought to be found in the universe has been located. The so-called ‘missing baryon problem’ emerged when cosmologists in the late nineties predicted that 5 per cent of the universe should be made of normal matter. However, when they counted … Read more
