Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, these stellar oddities have puzzled astronomers for more than 70 years. Now, new results using the NASA/ESA Hubble Space Telescope are finally revealing […]
Families of the astronauts lost in the space shuttle Challenger accident gathered back at the launch site Thursday to mark that tragic day 40 years ago.

A new study has examined how future human missions to Mars could access one of the planet’s most vital resources—water. The “Martian aqua: occurrence of water and appraisal of acquisition technologies” paper, published in the Advances in Space Research journal, presents a comparative analysis of potential water acquisition technologies for use on the red planet. […]
Space debris—the thousands of pieces of human-made objects abandoned in Earth’s orbit—pose a risk to humans when they fall to the ground. To locate possible crash sites, a Johns Hopkins University scientist has helped to devise a way to track falling debris using existing networks of earthquake-detecting seismometers.

In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches pressures similar to the core of the sun. That process happens within a miniscule amount of space and time. […]
Physicists have used a new optical centrifuge to control the rotation of molecules suspended in liquid helium nano-droplets, bringing them a step closer to demystifying the behavior of exotic, frictionless superfluids.

Scientists analyzing data from heavy ion collisions at the Large Hadron Collider (LHC)—the world’s most powerful particle collider, located at CERN, the European Organization for Nuclear Research—have new evidence that a pattern of “flow” observed in particles streaming from these collisions reflects those particles’ collective behavior. The measurements reveal how the distribution of particles is […]
Researchers have reported new experimental results addressing the origin of rare proton-rich isotopes heavier than iron, called p-nuclei. Led by Artemis Tsantiri, then-graduate student at the Facility for Rare Isotope Beams (FRIB) and current postdoctoral fellow at the University of Regina in Canada, the study presents the first rare isotope beam measurement of proton capture […]
Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical entanglement can be used to measure several physical parameters simultaneously with greater precision.

The Tuatha Dé Danann were called the Shining Ones, an ancient pre-Celtic Irish tribe, the fifth one that invaded the island in ancient times. They would later be associated with Elven or Fairy Folk, but in Irish myths, they weren’t anything like the fairies of folklore today.
This tribe was […]

When we think of woolly mammoths, we think of creatures that walked the Earth tens of thousands of years ago before the entire species became extinct due to the warming of the planet. But a new study shows that not all of them perished this early, and scientists are narrowing […]
