NASA’s Opportunity Mars rover is powered down. science operations on hold, in a bid to weather a huge dust storm that is blocking the sunlight needed to re-charge the robot’s batteries and keep it from freezing.
Astronomers have detected microwave emissions from three protoplanetary disks that apparently are generated by vast clouds of tiny, spinning nanodiamonds, tiny motes of carbon found in star-forming regions
NASA’s Curiosity Mars rover has detected a wide range of organic compounds on the red planet along with signs of seasonal variations in background methane levels, a possible indicator of biological activity.
Spectrographic data indicates several unusual compact dusty objects are circling the supermassive black hole at the core of the Milky Way, the possible result of stellar mergers triggered by the hole’s titanic gravity.
More than a decade of observations shows any planets orbiting the two main stars in the nearby Alpha Centauri system are not being blasted by dangerous levels of radiation that would be hostile to life.
NASA’s New Horizons probe, three years outbound from Pluto, has woken from electronic hibernation, healthy and on course for a New Year’s Day flyby of an even more remote Kuiper Belt object nicknamed Ultima Thule.
Astronomers are searching for a presumed “Planet Nine” in the extreme outer solar system whose gravity could explain unusual orbits of several remote bodies. New research suggests Planet Nine may not be necessary.
Detection of a small boulder-size asteroid hurtling toward Earth 2 June served as a real-world test of the advance warning systems in place to find, track and characterise potentially threatening bodies.
NASA’s Dawn spacecraft is in the process of dropping into its final, lowest-ever orbit around the dwarf planet Ceres, allowing it to make repeated passes within 50 kilometres (30 miles) of the surface.
