Newly spotted black hole has mass of 17 billion Suns, adding another daily
An accretion disk 7 light-years across powers an exceptionally bright galaxy. Enlarge (credit: ESO/M. Kornmesser) Quasars initially confused astronomers when they were discovered. First identified as sources of radio-fre.....»»
Q&A: If Russia is developing some kind of space-based weapon, Putin may never get to use it
News of a possible Russian satellite-destroying, space-based nuclear weapon sent shock waves through Washington this week. Some officials responded with considerable alarm, while others insisted that such concern is—for the moment—an overreaction.....»»
Variability of bat nasal bone morphology found to determine ultrasonic localization
Japanese horseshoe bats—or Nihon Kikugakushira—emit high-amplitude, ultrasonic waves from their nostrils. Several ultrasound-related studies have previously attempted to address the significant regional variability noted in bats' nasal morphologi.....»»
Astronomers are figuring out what causes incredibly bright flashes in space
Some of the oddest cosmic phenomena are short but powerful flashes called fast radio bursts. Now astronomers have observed one before and after it occurred,.....»»
Another clue into the true nature of fast radio bursts
Fast radio bursts (FRBs) are strange events. They can last only milliseconds, but during that time can outshine a galaxy. Some FRBs are repeaters, meaning that they can occur more than once from the same location, while others seem to occur just once.....»»
New chip opens door to AI computing at light speed
University of Pennsylvania engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing speed of computers.....»»
Apple Music launches new personalized ‘Love’ and ‘Heartbreak’ stations
Timely for Valentine’s Day, Apple Music has launched two new personalized radio stations, available now for Apple Music subscribers. The ‘Love Station’ has a romantic theme featuring songs about falling in love, whereas ‘Heartbreak’ feat.....»»
NASA telescopes find new clues about mysterious deep space signals
What's causing mysterious bursts of radio waves from deep space? Astronomers may be a step closer to providing one answer to that question. Two NASA X-ray telescopes recently observed one of such events—known as a fast radio burst—mere minutes be.....»»

Evidence that atomically thin hafnium telluride is an excitonic insulator
The condensation of excitons with non-zero momentum can give rise to so-called charge density waves (CDW). This phenomenon can prompt the transition of materials into a fascinating new quantum phase, known as an excitonic insulator......»»
Chinese astronomers find radio pulsar in a supernova remnant
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from the Nanjing University in China and elsewhere, have detected a radio pulsar in a supernova remnant known as CTB 87. The finding is reported in a paper published.....»»
NASA"s new experimental antenna tracks deep space laser
