5+ day, 6+ hour ago   (1103+ words) Black hole ringdown waves may reveal hidden matter or new physics through distinct changes in frequency and damping. (CREDIT: Nagoya University) After two black holes collide, the newly formed object does not immediately become quiet. It vibrates, sending gravitational waves…...

1+ week, 1+ day ago   (915+ words) Researchers observed bright flares of X-ray emissions, produced as gas falls into a supermassive black hole. (CREDIT: Dan Wilkins) A black hole nearly 800 million light-years away briefly revealed something that should ordinarily have been hidden from view. The discovery, published…...

1+ week, 6+ day ago   (1201+ words) Experiments show strong stellar magnetic fields can stop coronal mass ejections, helping explain why astronomers rarely detect them. (CREDIT: Shutterstock) Some of the most active stars in the galaxy appear capable of producing enormous eruptions, yet astronomers rarely see those…...

2+ week, 2+ day ago   (899+ words) Information fills hard drives, crosses computer networks and describes the properties of physical systems. One physicist argues it may also have something far more surprising: measurable mass. Dr. Melvin Vopson of the University of Portsmouth has proposed an experiment designed…...

2+ week, 5+ day ago   (1074+ words) An ADN green rocket thruster ignited electrically at room temperature, eliminating the need for a preheated catalyst bed. (CREDIT: Wikimedia / AI-Generated / CC BY-SA 4.0) An experimental “green” rocket thruster has fired successfully using ammonium dinitramide fuel without the catalyst bed normally…...

3+ week, 1+ day ago   (693+ words) That assumption may not hold. A team from Perimeter Institute and the University of Maryland reports that the conversion process can trigger powerful nonlinear effects in plasma. Those effects quickly disrupt the resonance that drives energy transfer, shutting the process…...

3+ week, 6+ day ago   (1389+ words) A new study captures the first clear evidence of ambipolar diffusion, a process that allows stars to form from dense cosmic clouds. (CREDIT: Shutterstock) Deep within a dark cloud in the constellation Taurus, a quiet shift is taking place. It…...

4+ week, 1+ day ago   (1202+ words) Color representation of the Helix Nebula. (CREDIT: Pieter van Dokkum et al, Nature) The Helix Nebula is shedding more than a spectacular glow. Far beyond its bright central ring, fragments from a dying star are being torn apart as they…...
