Astronomers have measured all the starlight that has managed to escape into space over the history of the universe.It amounts to 4 x 1084 particles of light, or photons. That’s roughly equivalent to all the photons the sun would emit if it burned for 100 billion trillion years — long
A really weird form of matter found in ultradense objects such as neutron stars is looking like a good candidate for the strongest material in the Universe. According to new calculations, it clocks in at a massive 10 billion times stronger than steel."This is a crazy-big figure," physicist Charles Horowitz
It’s been nearly a century since scientists first theorized that the Universe was expanding, and that the farther away a galaxy was from us, the faster it appears to recede. This isn’t because galaxies are physically moving away from us, but rather because the Universe is full of gravitationally-bound objects,
A “monster galaxy” that formed just one billion years after the Big Bang is spewing out stars at such a fast rate it will be consumed within the next 100 million years, scientists have discovered. By mapping the COSMOS-AzTEC-1 galaxy, which is located 12.4 billion light years away, researchers were able
Forget mere chemical reactions; in space, matter-energy conversion creates unprecedentedly powerful explosive events.Here are the 7 most powerful natural displays of cosmic fireworks.7. Type Ia supernova: when two white dwarf stars collide, they initiate a runaway fusion reaction, destroying both stellar remnants.6. Core-collapse supernova: when a supermassive star runs out of
The universe's missing matter has been found, and it's floating between the stars.Researchers who study the ancient history of the universe know how much ordinary matter — matter that makes up baryons, a class of subatomic particles that includes protons and neutrons — the universe created during the Big Bang.
Astronomers have discovered a massive supercluster of galaxies located approximately 4 billion light-years from Earth – and not only is it one of the largest known structures in the cosmos, it's also the most distant supercluster we've ever observed.See, in space, everything is a question of perspective.
