Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with ...
Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe's largest galaxies formed. The paper outlining the ...
The worlds of the solar system are exciting and, so far, mostly pristine places for planetary scientists to study. As space missions continue to travel to Mars, Europa, asteroids and other worlds, questions arise about keeping ...
NASA is about to launch a space observatory that could help settle some of the biggest mysteries in modern astronomy. The Nancy Grace Roman Space Telescope will study how the universe began, what it is made of and how it ...
According to current understanding, the universe is expanding—and is doing so at an accelerating rate. This is believed to be caused by something called the cosmological constant, which was first proposed by Albert Einstein ...
For decades, astronomers have cast galaxy mergers as the universe's ultimate relationship drama: two galaxies collide, chaos erupts, black holes awaken and star formation comes to a screeching halt. Upending this long-held ...
One of the deepest ambitions in modern physics is understanding how the fabric of space and time could emerge from fundamental quantum degrees of freedom to establish a quantum theory of gravity.
The Milky Way may have undergone a dramatic change in orientation during its history, according to new research that helps explain a long-standing mystery about our galaxy. Using supercomputer simulations of galaxies like ...
A new study by Queen Mary University of London mathematician Professor Ginestra Bianconi proposes a new perspective on one of the deepest questions in modern physics: How can the universe become increasingly structured and ...
Astronomers have used the ages of more than 155,000 stars in the Milky Way to independently estimate the age of the universe, and their findings may be good news for the standard cosmological model. The new research was reported ...
