First candidate: Alpha Centauri, a system similar to ours, ''only'' 4.3 light years away. This study is the subject of a publication in the journal Nature Communications. (2021-02-10)

Super-Earth atmospheres probed at Sandia's Z machine
Sandia National Laboratorie' Z machine has replicated the gravitational pressures on so-called ''super-Earths'' to determine which might maintain atmospheres that could support life. Astronomers believe that super-Earths -- collections of rocks up to eight times larger than Earth -- exist in the millions in our galaxy. ''The question before us is whether any of these super planets are actually Earthlike, with active geological processes, atmospheres and magnetic fields,'' said Sandia physicist Joshua Townsend. The researchers found seven. (2021-02-09)

Can super-Earth interior dynamics set the table for habitability?
New research led by Carnegie's Yingwei Fei provides a framework for understanding the interiors of super-Earths--rocky exoplanets between 1.5 and 2 times the size of our home planet--which is a prerequisite to assess their potential for habitability. Planets of this size are among the most abundant in exoplanetary systems. (2021-02-09)

Exoplanet around distant star resembles reputed 'Planet Nine' in our solar system
Astronomers think planets can exist in orbits far from their star, and propose a two-step process: interactions with the star or inner planets kick it out of the inner system, and then a passing star stabilizes the orbit to keep it bound. Such a scenario could explain the hypothesized ''Planet Nine'' in our solar system. Astronomers has now confirmed that one binary star system, HD 106906, has a planet in a bound, highly eccentric orbit. (2020-12-10)

Best region for life on Mars was far below surface
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes. The study, published in the journal Science Advances, may help resolve what's known as the faint young sun paradox - a lingering key question in Mars science. (2020-12-02)

The continents will reunite again in the deep future. And a new study, presented today during an online poster session at the meeting of the American Geophysical Union, suggests that the future arrangement of this supercontinent could dramatically impact the habitability and climate stability of Earth. The findings also have implications for searching for life on other planets. (2020-12-01)

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. (2020-11-23)

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. (2020-11-17)

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)

Researchers present wild theory: Water may be naturally occurring on all rocky planets
