A new test proves how to make the Event Horizon Telescope even better
Want a clear view of a supermassive black hole's environment? It's an incredible observational challenge. The extreme gravity bends light as it passes through and blurs the details of the event horizon, the region closest to the black hole. Astronome.....»»
Gravitational wave observatories could detect primordial black holes speeding through the solar system
Cosmologists have long hypothesized that the conditions of the early universe could have caused the formation of black holes not long after the Big Bang. These "primordial black holes" have a much wider mass range than those that formed in the later.....»»
Q&A: Astronomers await a once-in-80-year stellar explosion
We sat down with Carnegie Science Observatories theoretical astrophysicist Tony Prio to talk about T Coronae Borealis, the stellar explosion that occurs once every 80 years and is due to light up in the coming months......»»
Webb discovers six new "rogue worlds" that provide clues to star formation
Rogue planets, or free-floating planetary-mass objects (FFPMOs), are planet-sized objects that either formed in interstellar space or were part of a planetary system before gravitational perturbations kicked them out......»»
From harmony to civil war: When language turns deadly
For years, Jaroslav Tir has been pondering a perplexing mystery: Why do some countries where a multi-ethnic populace once lived together in harmony devolve into civil war, slaughter and ethnic cleansing?.....»»
Hubble zooms into the rosy tendrils of Andromeda
Clusters of stars set the interstellar medium ablaze in the Andromeda galaxy about 2.5 million light-years away. Also known as M31, Andromeda is the Milky Way's closest major galaxy. It measures approximately 152,000 light-years across and, with almo.....»»
What a submerged ancient bridge discovered in a Spanish cave reveals about early human settlement
A new study led by the University of South Florida has shed light on the human colonization of the western Mediterranean, revealing that humans settled there much earlier than previously believed. This research, detailed in a recent issue of the jour.....»»
Light-activated polymerization methods unlock new possibilities for intracellular applications
Synthetic polymers play a crucial role in cell biology, serving as delivery vehicles for DNA and drugs, acting as fluorescent probes for cellular sensing, functioning as bioinks for tissue engineering, and mimicking biological functionality (e.g., ar.....»»
