Large Hadron Collider reveals evidence of Big Bang matter in surprisingly small collisions Quark–gluon plasma (QGP) is an unusual state of matter that appears under tremendous pressure and heat. At temperatures exceeding 100,000 times those at the Sun’s center, particles such as protons and neutrons can no longer maintain their normal structure. Instead, they break apart into quarks and the gluons that ordinarily bind them together. Physicists believe that this was the state of matter throughout the universe during the first millionths of a second after the Big Bang. Nearly 14 billion years later, researchers can briefly recreate these extraordinary conditions by smashing atomic nuclei together at extremely high energies inside the LHC.

How researchers debunked ‘race science’: ‘a triumph of scientific self-correction’ An account of how nineteenth-century studies aiming to find a biological basis for human races were dismantled by good scientific practices — although their effects are still felt today.

Lights in the sky ✨ The telescope gazing at the Milky Way in admiration is the Danish 1.54-meter telescope, hosted at La Silla in #Chile. And do not worry, the green glow we see in this image –too faint to be seen with the naked eye– is not a result of urban light pollution. This is a natural phenomenon known as airglow. What causes it? Find out: https://www.eso.org/public/images/potw2645a/ 📷 J. Rodrigues/ESO #astrodon #astronomy #astrophysics #space #science

Three-Body Orbits [Gallery] There are no generalized solutions to the three-body problem. Say you have three planets orbiting each other: it’s impossible to calculate how they will move using Newton’s laws of motion and gravity. Unlike the two-body problem, the three-body problem has no general closed-form analytic solution. The differential equations that govern the motions of three gravitating bodies are not integrable and cannot be solved to give explicit formulas for the positions of the bodies as a function of time. For most initial conditions, the dynamical system for three orbiting bodies is chaotic, and the only way to predict their motions is to estimate them using numerical methods. But thousands of stable three-body orbits have been found — their paths repeat after a given interval. The Three Body Orbits website is an atlas of some of those orbits: you can watch each three-body system play itself out in a wide variety of different shapes and complexities. There’s this simple figure 8, this slightly less simple one, and this one that looks like a spirograph. Underlying Source: www.threebodyorbits.com

A push by China to revive its mangrove forests is paying off. Not only have mangroves colonized large areas of coastline, but the new forests have drawn scores of new bird species.
