Biggest cosmic mystery ‘step closer’ to solution
The nature of this quirk, which allowed matter to dominate the Universe at the expense of antimatter, remains a mystery. Now, results from an experiment in Japan could help researchers solve the puzzle – one of the biggest in science. It hinges on a difference in the way matter and antimatter particles behave.
The world that’s familiar to us – including all the everyday objects we can touch – is made up of matter. The fundamental building blocks of matter are sub-atomic particles, such as electrons, quarks and neutrinos…more
‘Alien comet’ visitor has weird composition
The interstellar comet 2I/Borisov was detected in our Solar System last year. This mysterious visitor from the depths of space has provided astronomers with an unprecedented opportunity to compare it to comets that formed around the Sun. New data suggests it contains large amounts of carbon monoxide – a possible clue to where it was “born”…more
Hubble’s 30th anniversary image has been turned into a 3D “spaceflight” experience.
Experts created this visualisation showing the Giant Red Nebula and its smaller blue neighbour, which lie in a satellite-galaxy of the Milky Way…more
Hubble looks back in time 12.6 billion years
Experts have created a spectacular visualisation of the “Hubble Ultra Deep Field” – one of the deepest optical images of the Universe ever taken. It was assembled for the 30th anniversary of the space telescope’s launch…more
Event Horizon Telescope: Black hole produces twisting jet
Hubble’s 30th anniversary image has been turned into a 3D “spaceflight” experience. One year on from publishing the first ever image of a black hole, the team behind that historic breakthrough is back with a new picture.
This time we’re being shown the base of a colossal jet of excited gas, or plasma, screaming away from another black hole at near light-speed. The scene was actually in the “background” of the original target…more
