Long ago, Mars had massive watersheds—now finally mapped

What can mapped drainage systems on Mars teach scientists about the red planet’s watery past? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of scientists from the University of Texas at...

Close-up images show how stars explode in real time

Astronomers have captured images of two stellar explosions—known as novae—within days of their eruption and in unprecedented detail. The breakthrough provides direct evidence that these explosions are more complex than previously thought, with multiple outflows of...

An adolescent growth spurt in young stars helps giant planets form

Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star called a protoplanetary disk. As the name makes clear, this is where...

Rydberg-atom detector conquers a new spectral frontier

A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the Center of New Technologies, University of Warsaw has developed a new method for measuring elusive terahertz signals using a “quantum antenna.” Go to...
