- New evidence for controversial galaxies without dark matter uncovered by Hubble. If confirmed, the ghostly galaxies would point to an alternative method for building galaxies. Author: "The thing is, we have no idea how star formation would proceed in the absence of dark matter." http://www.astronomy.com/news/2019/10/hubble-reveals-that-galaxies-without-dark-matter-really-exist 60 comments science
- A Mars colony could grow enough food to feed 1 million people within 100 years of arriving, finds new study. Though we'd have to import a lot of food to start, the researchers say we could eventually shift to a sustainable, Martian-grown diet rich in bugs, algae, and staples like beans and potatoes. http://www.astronomy.com/news/2019/09/we-could-feed-one-million-people-living-in-colonies-on-mars 27 comments worldnews

- The cores of 'dead planets' can survive 100 million to 1 billion years after their stars expand 100-fold into red giants. Because of this, astronomers are hoping to get a glimpse at Earth's future by looking for radio waves emitted from exoplanetary remnants around other stars. http://www.astronomy.com/news/2019/08/astronomers-search-for-radio-signals-from-dead-planets 4 comments space

- Supernovae may have led to humans walking upright millions of years ago. New research outlines how a series of nearby supernovae would have triggered intense lightning storms, igniting wildfires that turned African forests into savannas, causing humans to stand upright to better see prey. http://www.astronomy.com/news/2019/05/could-a-supernova-have-made-humans-bipedal 12 comments worldnews

- Auroras act as "speed bumps" that drag satellites closer to Earth, new research shows. The auroras heat air pockets, causing them to drift upward, like bubbles in a lava lamp. Satellites then experience drag within the air pockets, which slows them down and causes them to fall closer to Earth. http://www.astronomy.com/news/2019/04/speed-bumps-from-auroras-can-slow-down-satellites 8 comments science
- Massive flare erupts from tiny, ultra-cool star, boosting its brightness by 10,000-fold.

- Astronomers find the most distant known object in the solar system. "Farfarout" is a 250-mile-wide (400 km) dwarf planet located about 140 times farther from the Sun than Earth (3.5 times farther than Pluto), and it soon may help serve as evidence for a massive, far-flung world called Planet 9. http://www.astronomy.com/news/2019/03/a-map-to-planet-nine-charting-the-solar-systems-most-distant-worlds 12 comments space
- 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
