Planetary Interiors in TRAPPIST-1 System Could be Affected by Solar Flares

In a recent study published in The Astrophysical Journal Letters, an international team of researchers led by the University of Cologne in Germany examined how solar flares erupted by the TRAPPIST-1 star could affect the interior heating of its orbiting exoplanets. This study holds the potential to help us better understand how solar flares affect planetary evolution. The TRAPPIST-1 system is an exolanetary system located approximately 39 light-years from Earth with at least seven potentially rocky exoplanets in orbit around a star that has 12 times less mass than our own Sun. Since the parent star is much smaller than our own Sun, then the the planetary orbits within the TRAPPIST-1 system are much smaller than our own solar system, as well. So, how can this study help us better understand the potential habitability of planets in the TRAPPIST-1 system?

Is Mining in Space Socially Acceptable?

Traditional mining has been subject to a negative stigma for some time. People, especially in developed countries, have a relatively negative view of this necessary economic activity. Primarily that is due to its environmental impacts – greenhouse gas emissions and habitat destruction are some of the effects that give the industry its negative image. Mining in space is an entirely different proposition – any greenhouse gases emitted on the Moon or asteroids are inconsequential, and there is no habitat to speak of on these barren rocks. So what is the general public’s opinion on mining in space? A paper from a group of researchers in Australia, one of the countries most impacted by the effects of terrestrial mining, now gives us an answer.
