Quantum Paradox Experiment May Lead to More Accurate Clocks and Sensors

More accurate clocks and sensors may result from a recently proposed experiment, linking an Einstein-devised paradox to quantum mechanics. University of Queensland physicist Dr Magdalena Zych said the international collaboration aimed to test Einstein’s twin paradox using quantum particles in a ‘superposition’ state.

Soil on Moon and Mars Likely to Support Crops

Researchers at Wageningen University & Research in the Netherlands have produced crops in Mars and Moon soil simulant developed by NASA. The research supports the idea that it would not only be possible to grow food on Mars and the Moon to feed future settlers, but also to obtain viable seed from crops grown there.

Astronomers Use Giant Galaxy Cluster as X-ray Magnifying Lens

Astronomers at MIT and elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, high-energy stages of star formation.

Black Holes Stunt Growth of Dwarf Galaxies

Astronomers at the University of California, Riverside, have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star formation.

Study Suggests Ice on Lunar South Pole May Have More than One Source

The discovery of ice deposits in craters scattered across the Moon’s south pole has helped to renew interest in exploring the lunar surface, but no one is sure exactly when or how that ice got there. A new study published in the journal Icarus suggests that while a majority of those deposits are likely billions of years old, some may be much more recent.

The Milky Way Kidnapped Several Tiny Galaxies from Its Neighbor

Just like the moon orbits the Earth, and the Earth orbits the sun, galaxies orbit each other according to the predictions of cosmology. For example, more than 50 discovered satellite galaxies orbit our own galaxy, the Milky Way. The largest of these is the Large Magellanic Cloud, or LMC, a large dwarf galaxy that resembles a faint cloud in the Southern Hemisphere night sky.

Liquifying a Rocky Exoplanet

Rocky exoplanets that are around Earth-size are comparatively small, which makes them incredibly difficult to detect and characterize using telescopes. What are the optimal conditions to find such small planets that linger in the darkness?

Physicists Have Found a Way to 'Hear' Dark Matter

Physicists at Stockholm University and the Max Planck Institute for Physics have turned to plasmas in a proposal that could revolutionize the search for the elusive dark matter.
