At the 244th meeting of the American Astronomical Society (AAS), researchers unveiled findings from a pioneering high-angular resolution program that sheds new light on the process of planet formation in circumstellar disks around young stars in bina.....»»
As Paris preps for Olympics, survey finds Coloradans still feel ambivalent about hosting
More than five decades after Denver said "thanks, but no thanks" to hosting the 1976 Winter Olympics, large numbers of Coloradans still feel ambivalent about going for gold......»»
How did a satellite galaxy of the Milky Way come to be? Physicists offer an explanation
Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface brightness. How this galaxy originated remains unclear......»»
Haiku poems may shine a light on humans" relationship with insects, study suggests
Haiku poems have reflected humans' experiences in nature for hundreds of years, including observations of bugs and other wildlife. Recently, Penn State researchers analyzed which insects were mentioned the most in haiku—with butterflies, fireflies.....»»
How tiny cracks lead to large-scale faults
The geological and topographical features that make up the world we live in are shaped in large part by faults and fractures in Earth's brittle crust. Faults arise from preexisting microscopic imperfections within rock. When the rock is subjected to.....»»
Origins of fast radio bursts come into focus through polarized light
What scientists previously thought about where Fast Radio Bursts (FRBs) come from is just the tip of the iceberg, according to new research led by astronomers at the University of Toronto. The mysteries of the millisecond-long cosmic explosions are u.....»»
Investigating collective motions in schools of zebrafish could deepen understanding of active systems
Active systems display a wide range of complex and fascinating behaviors, many of which are not yet fully understood. Found on scales ranging from microbes and self-propelling particles to large groups of fish, birds, and mammals, they are made up of.....»»
NASA watches Mars light up during epic solar storm
In addition to producing auroras, a recent extreme storm provided more detail on how much radiation future astronauts could encounter on the Red Planet......»»
