A small team of researchers announced that its correspondingly small telescope picked up a signal produced by the very first stars in our Universe.
This black hole resides in a luminous quasar and its light reaches us from when the Universe was only 5 percent of its current age — just 690 million years after the Big Bang.
Astronomers report that they have detected the second most distant dusty, star-forming galaxy ever found in the universe -- born in the first one billion years after the Big Bang. It is the oldest object ever detected by the LMT.
Physicists have a new scenario of the universe's expansion at the Big Bang that may explain why our universe has three large spatial dimensions.
The most distant galactic magnetic field that has ever been observed provides intriguing clues about the evolution of magnetism in the unfolding universe.
When running Hawking and Hartles’ as well as Vilenkin’s, math, the new team didn’t get the teeny quantum fluctuations required to create today’s universe.
A new study suggests that the early Solar System was quickly divided in two, with the rapidly forming Jupiter creating the dividing line.
Did our sun have a twin when it was born 4.5 billion years ago? Almost certainly yes -- though not an identical twin.
New work from a team led by Carnegie’s Eduardo Bañados has discovered 63 new quasars from when the universe was only a billion years old.
Astronomers have used gravitational lensing to detect an incredibly faint early-universe galaxy 13 billion light years away.
Research has found new persuasive evidence that could help solve a longstanding mystery in astrophysics: why did the pace of star formation in the universe slow down some 11 billion years ago?
International collaboration including MPQ scientists sets a new value for the antiproton mass relative to the electron with unprecedented precision.
(PhysOrg.com) -- Suppose at some point the universe ceases to expand, and instead begins collapsing in on itself (as in the “Big Crunch” scenario), and eventually becomes a supermassive black hole. The black hole’s extreme mass produces an extremely strong gravitational field. Through a gravitational version of the so-called Schwinger mechanism, this gravitational field converts virtual particle-antiparticle pairs from the surrounding quantum vacuum into real particle-antiparticle pairs. If the black hole is made from matter (antimatter), it could violently repel billions and billions of antiparticles (particles) out into space in a fraction of a second, creating an ejection event that would look quite similar to a Big Bang.
By shooting a beam of neutrinos through a small slice of the Earth under Japan, physicists say they
Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA
