Astronomers using the MeerKAT telescope discovered a hydroxyl megamaser in a galactic merger 8 billion light-years away, amplified by gravitational lensing and operating at radio wavelengths.

Introduction:Attosecond pulses capture ultrafast electron and light–matter dynamics on the shortest timescales accessible to controlled experiments ...

The space between galaxies is not empty. In a new map of the early universe, those “blank” stretches take on a faint, hydrogen-blue glow that had mostly escaped surveys until now. Astronomers working ...

Scientists studying distant exoplanets believe that plant life on some worlds could appear red rather than green. The reason lies in the type of light emitted by the host star and how organisms evolve ...
