- HD 10180 planets are roughly spaced in the same proportions as our solar system. This suggests there is some common type of resonance in a planet-forming disk that builds worlds according to an empirical relationship called the Titus-Bode Law. http://cot.ag/9fm7bi 10 comments space
- Astronomers capture a real image of two baby stars locked in a gravitational waltz that's twisting their planet-forming disks into a pretzel-shaped knot. The unprecedented look gives researchers a glimpse into the complex formation of the most common type of stellar setup — binary stars. http://www.astronomy.com/news/2019/10/baby-stars-found-twisting-planet-forming-disks-into-a-pretzel 176 comments science
- Scientists have found evidence of a planet forming far from its host star, a discovery that could challenge the prevailing wisdom about how planets take shape. The location poses problems for the leading planet-formation theory, which holds that worlds grow slowly over tens of millions of years. http://www.space.com/21553-hubble-most-distantly-orbiting-exoplanet.html 5 comments science

- Astronomers find Al-26, a radioactive form of aluminum, can heat up and dry out the large boulders (called planetesimals) that collide to form planets. More Al-26 leads to a dry, desiccated planet, while a lack of Al-26 allows water worlds to form, some of which have up to 50% water by mass. http://www.astronomy.com/news/2019/02/a-radioactive-metal-may-be-vital-for-building-water-worlds 3 comments science

- A magnetic shield at Mars could help retain atmosphere for terraforming. To enable this, researchers are proposing to create an artificial charged particle ring (similar in form to a ‘radiation belt’), around the planet possibly formed by ejecting matter from one of the moons of Mars. https://www.sciencedirect.com/science/article/abs/pii/S0094576521005099?via%3Dihub 25 comments science
- There are hidden orbits in the solar system that can extremely shorten the flight times of asteroids and space probes. These arc-shaped “super highways” are created by gravity resonances of the large planets and form a kind of high-speed network, as physical simulations reveal. https://advances.sciencemag.org/content/6/48/eabd1313 15 comments science

- Astronomers evaluate which galaxies are best suited for alien life. Large spirals like the Milky Way have lots of heavy elements, helping them form rocky planets, but they also have more dangerous supernova.

- Despite boiling temperatures, Mercury manages to maintain stable glaciers. According to new research, the glaciers, which are up to 160 feet (50 m) thick and 50 million years old, formed when free-floating water ice from comet and asteroid impacts settled in deep craters on the planet's night side. http://www.astronomy.com/news/2019/01/exploring-glaciers-on-mercury-a-planet-plagued-by-boiling-temperatures 9 comments science
