NASA’s Roman Space Telescope is set to embark on a deep-sky survey that could capture nearly 100,000 cosmic explosions, shedding light on everything from dark energy to black hole physics. Its ...

A team of researchers proposes a new vision of the Universe's first moments. Their model eliminates the need for traditional speculative hypotheses. Cosmologists have long worked with the inflation ...

Astronomers have discovered the oldest and most distant black hole — a behemoth that likely formed at the dawn of the universe, more than 13 billion years ago. The black hole lies at the center of a ...

The black hole and its home galaxy, together dubbed CAPERS-LRD-z9, existed just 500 million years after the Big Bang. Its properties could help researchers understand what the universe was like in ...

Astronomers know that the universe began in an extremely hot, dense state, the Big Bang, about 13.8 billion years ago, and then cooled rapidly as it expanded. Roughly 400,000 years later, temperatures ...
