The final SPIRE Dark Field image map created by combining the Blue (250 micrometres), Green (350 micrometres) and Red (500 micrometres) SPIRE camera channels together, each channel stacking a total of 141 individual images on top of each other.
'Hidden galaxies' could be smoking gun in universe riddle
Astronomers have peered back in time to find what looks like a population of 'hidden' galaxies that could hold the key to unlocking some of the universe's secrets. If their existence is confirmed it would "effectively break current models of galaxy…
The giant radio jets stretching six million light-years across and an enormous supermassive black hole at the heart of spiral galaxy J23453268−0449256, as imaged by the Giant Metrewave Radio Telescope.
Cosmic anomaly hints at frightening future for Milky Way
A terrifying glimpse at one potential fate of our Milky Way galaxy has come to light thanks to the discovery of a cosmic anomaly that challenges our understanding of the universe. An international team of astronomers led by CHRIST University, Bangal…
New research suggests at least two mass extinction events in Earth's history were caused by a nearby supernova. Pictured is an example of one of these stellar explosions, Supernova 1987a (centre), within a neighbouring galaxy to our Milky Way called the Large Magellanic Cloud.
Violent supernovae 'triggered at least two Earth extinctions'
drupal-media[data-view-mode=half_page_width] { display: inline-block; width: 50%; } At least two mass extinction events in Earth's history were likely caused by the "devastating" effects of nearby supernova explosions, a new study suggest…
The "remarkable" XRT 200515 cosmic explosion observed by NASA's Chandra X-ray Observatory.
Mystery of 'remarkable' cosmic explosion that lay hidden for years
The "needle in the haystack" discovery of a powerful explosion from a mysterious unknown object outside our galaxy has excited astronomers. It went unnoticed for years within a vast, two decade-long archive of observations by NASA's Chandra X-ray Ob…
The newly-discovered giant radio galaxy ‘Inkathazo’. The glowing plasma jets, as seen by the MeerKAT telescope, are shown in red and yellow. The starlight from other surrounding galaxies can be seen in the background.
'Troublesome' radio galaxy 32 times size of Milky Way spotted
Astronomers have discovered an extraordinary new giant radio galaxy with plasma jets 32 times the size of our Milky Way. Measuring 3.3 million light-years from end-to-end, the cosmic megastructure was spotted by South Africa's MeerKAT telescope and…

Dark energy 'doesn’t exist' so can't be pushing 'lumpy' Universe apart – study
One of the biggest mysteries in science – dark energy – doesn't actually exist, according to researchers looking to solve the riddle of how the Universe is expanding. For the past 100 years, physicists have generally assumed that the cosmos is…

2 MILLION mph galaxy smash-up seen in unprecedented detail
A massive collision of galaxies sparked by one travelling at a scarcely-believable 2 million mph (3.2 million km/h) has been seen in unprecedented detail by one of Earth's most powerful telescopes. The dramatic impact was observed in Stephan's Quint…
Amount of stars (white) produced in universes with different dark energy densities. Clockwise, from top left, no dark energy, same dark energy density as in our Universe, 10 and 30 times the dark energy density in our Universe.
A formula for life? New model calculates chances of intelligent beings in our Universe and beyond
The chances of intelligent life emerging in our Universe – and in any hypothetical ones beyond it – can be estimated by a new theoretical model which has echoes of the famous Drake Equation. This was the formula that American astronomer Dr Frank Dra…
