materialsTwo Quintillion Tons of Metal or Dense Oxides Found on the Moon

A large mass of material has been discovered beneath the largest crater on the Moon, the South Pole-Aitken basin, and it may contain metal from an asteroid that crashed into the Moon and formed the crater. If this is a …

MarsMars Curiosity Detects High Methane Levels Which Could Be Life

This week, NASA’s Curiosity Mars rover found a surprising result: the largest amount of methane ever measured during the mission — about 21 parts per billion units by volume (ppbv). One ppbv means that if you take a volume of …

science2.8 Trillion Tons of Nearly Fresh Water Found Under the Ocean

Low-salinity submarine groundwater contained within continental shelves is a global phenomenon. While low-salinity groundwater is thought to be abundant, its distribution and volume worldwide is poorly understood due to the limited number of observations. Researchers have imaged laterally continuous aquifers …

materialsDiamonds and Ion Qubits

There are three major competing Quantum computer technologies for qubits. They are nitrogen-vacancy (NV) centers in diamond lattices, trapped ions, and superconducting qubits. The benefit of trapped-ion systems is that the ions are inherently going to affect one another. They’re …

scienceThe Universe is 14 Billion Years Old But Visible Universe is 92 Billion Light Years Wide

The Universe is 13.7 billion years old. About five billion years ago, an energy field that we call dark energy became important. Dark energy is a repulsive form of gravity, which means that the expansion of the universe isn’t slowing …

astronomyImproved Telescope to Directly Image Alpha Centauri Exoplanets and Other Exoplanet Updates

1. Newly-built planet-finding instrument installed on Very Large Telescope aims to be first to directly image a habitable exoplanet. The instrument, called NEAR (Near Earths in the AlphaCen Region), is designed to hunt for exoplanets in our neighbouring star system, …
