A new beat in quantum matter
Oscillatory behaviors are ubiquitous in Nature, ranging from the orbits of planets to the periodic motion of a swing. In pure crystalline systems, presenting a perfect spatially-periodic structure, the fundamental laws of quantum physics predict a remarkable and counter-intuitive oscillatory behavior: when subjected to a weak electric force, the electrons in the material do not undergo a net drift, but rather oscillate in space, a phenomenon known as Bloch oscillations.

Ancient zircon minerals from Mars reveal the elusive internal structure of the red planet
Analysis of an ancient meteorite from Mars suggests that the mineral zircon may be abundant on the surface of the red planet. By determining the age and hafnium isotope composition of these zircons, researchers from the University of Copenhagen have shown that a population of these crystals were sourced from the deep interior of Mars. If the researchers are correct, it means that the young zircons contain information about the deep, inaccessible interior of Mars, which provides insights into the internal structure of the planet.

Building blocks of life can form long before stars
An international team of scientists have shown that glycine, the simplest amino acid and an important building block of life, can form under the harsh conditions that govern chemistry in space. (2020-11-16)

Radioactive elements may be crucial to the habitability of rocky planets
The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from the radioactive decay of the heavy elements thorium and uranium drives plate tectonics and may be necessary for the planet to generate a magnetic field. Earth's magnetic field protects the planet from solar winds and cosmic rays. (2020-11-10)

Second alignment plane of solar system discovered
A study of comet motions indicates that the Solar System has a second alignment plane. Analytical investigation of the orbits of long-period comets shows that the aphelia of the comets, the point where they are farthest from the Sun, tend to fall close to either the well-known ecliptic plane where the planets reside or a newly discovered 'empty ecliptic.' This has important implications for models of how comets originally formed in the Solar System. (2020-09-29)

Geoscience: Cosmic diamonds formed during gigantic planetary collisions
Geoscientists from Goethe University have found the largest extraterrestrial diamonds ever discovered - a few tenths of a millimetre in size nevertheless - inside meteorites. Together with an international team of researchers, they have now been able to prove that these diamonds formed in the early period of our solar system when minor planets collided together or with large asteroids. These new data disprove the theory that they originated deep inside planets - similar to diamonds formed on Earth - at least the size of Mercury (PNAS). (2020-09-29)

Remnants of an ancient asteroid shed new light on the early solar system
Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system. Geological and geochemical records indicate that the Earth-Moon system experienced a period of frequent and cataclysmic impacts from asteroids and other bodies. It was thought that this period had a relatively sudden onset, but the researchers have found evidence that this bombardment period may have started much earlier, and decreased in intensity over time.

The team has recently published their findings in Nature. (2020-09-16)

From star to solar system: How protoplanetary rings form in primordial gas clouds
The star HL Tauri is glowing at the center of a system of concentric rings made from gas and dust and producing planets, one for each gap in the ring. Its discovery has shaken solar system origin theories to their core. Mayer Humi, a scientist from the Worcester Polytechnic Institute, believes it provides an apt study target for theories about protoplanetary rings around stars. The research is published in the Journal of Mathematical Physics. (2020-09-15)
