More confirmation needed to see if recently discovered object is a quark star.
Largest-ever radar study of near-Earth asteroids
Years’ worth of radar data from the now-destroyed Arecibo Observatory has helped detail almost 200 near-Earth asteroids.
Science in pictures
Check out atomic glimpses of graphene ribbons, double bubble microspheres, and a solar evaporator made from bone.
Sensor translates sign language into audio
With the help of machine learning, a skin-like sensor internalizes different stimuli, allowing it to read and interpret hand movement.
Black hole orbit oscillations shore up general relativity
Oscillations measured in the orbits of a pair of black holes have once again helped confirm predictions made using general relativity.
Energy generated in the blink of an eye
A tiny battery built into smart contact lenses produces its own power through eye blinking, relying on tears and oxygen to power its cells.
New material is a game changer in radiative cooling
A new coating designed for sub-ambient radiative cooling could help combat global warming by curbing energy use.
Dark matter from quantum gravity
Researchers at the Southern University of Science and Technology in China ask if gravitons can be promising candidates for dark matter components.
The road towards the first image of a black hole
Imaging a black hole is not an easy thing, it takes years of experiments, collaborations, grants, planning, and no small amount of luck.
Upper mass limit of massive stars revisited
Physicists at the Gemini Observatory have found a new mass limit for massive stars, and found it to be lower than previously thought.
