New observations of a far-flung galaxy cluster have left a group of scientists stumped as they ponder whether they’ve discovered a new form of physics. In their new paper, researchers Tessa Vernstrom ...

Aliens might be transmitting communications signals to each other across exoplanets, some astronomers think. Since these ...

Scientists are closing in on a long‑standing mystery in space physics: why some auroras erupt in sudden, explosive bursts ...

The waves' origin is unknown, so they hint at the existence of a new type of celestial object. The signal doesn't look like the kind that comes from stars, planets, or even dead stars. Mysterious ...

A new set of computer simulations may finally explain several long-standing mysteries surrounding gigantic radio "relics" that appear when galaxy clusters collide.

An international Ph.D. student in the School of Physics at the University of Sydney discovered unusual radio waves emanating from the center of the Milky Way prompting astronomers to seek evidence of ...

A research team has created a quantum antenna capable of precisely measuring terahertz frequency combs for the first time. A research team from the Faculty of Physics and the Centre for Quantum ...

A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the Center of New Technologies, ...

The universe is awash with strange radio signals, but astronomers have now detected a really bizarre one that repeats every hour, cycling through three different states. While they have some ideas ...

Physicists at Stanford University and SLAC have built a contraption they hope will detect dark matter, though exactly which theoretical particles they think they’ll find—hidden photons or little blips ...

Increasing CO2 levels are triggering changes in the ionosphere that will adversely affect signals, say scientists ...

Mysterious radio waves coming from the heart of the Milky Way have astronomers baffled. At this point, they have no idea what’s causing them, according to a new study published Tuesday in the ...
