Despite being the very first candidate planet discovered by our Kepler Mission, Kepler-1658b had a rocky road to confirmation. Ten years later, scientists have now confirmed that it is, in fact, a planet. It whips around its star every 3.85 days. Details: https://go.nasa.gov/2TDlaIl

One in five stars in our galaxy like the Sun have planets about the size of Earth and a surface temperature conducive to life, astronomers at UC Berkeley and University of Hawaii, Manoa now estimate.
The estimate was based on a statistical analysis of all the Kepler observations of NASA’s Kepler space telescope of the 200 billion stars in our galaxy.
China says it is working to develop a solar energy plant in space that could one day beam enough power back to Earth to light up an entire city.
If scientists can overcome the formidable technical challenges, the project would represent a monumental leap in combating the Earth’s addiction to dirty power sources which worsen air pollution and global warming.
A space-based solar power station could also provide an alternative to the current generation of earthbound and relatively ineffective renewable energy sources.

The Atacama Desert in Chile has been a hotbed of astronomical activity of late. Not only is it the site of Martian environmental simulations to test rover capabilities, it is also home to an project called SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars).
SPECULOOS is part of the ESO, the European Southern Observatory, and involves the use of four robotic telescopes for planet hunting. In particular, the telescopes look near to ultracool stars and brown dwarfs to search for Earth-sized exoplanets which can then be investigated in more detail by another telescope such as ESO’s forthcoming Extremely Large Telescope (ELT).
The four telescopes of SPECULOOS are named after Jupiter’s moons: Io, Europa, Ganymede, and Callisto, and each has a one meter primary mirror with cameras that are sensitive to near-infrared wavelengths. This accords with the type of light given off by the ultracool stars and brown dwarfs which are the telescopes’ targets.

NASA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon. The subterranean ocean is thought to have more water than all the water on Earth’s surface.
Identifying liquid water is crucial in the search for habitable worlds beyond Earth and for the search of life as we know it.

Lt Col Garretson — one of the USAF’s most farsighted and original thinkers — has been at the forefront of USAF strategy on the long-term future in projects such as Blue Horizons (on KurzweilAI — see video), Energy Horizons, Space Solar Power, the AF Futures Game, the USAF Strategic Environmental Assessment, and the USAF RPA Flight Plan. Now in this exclusive to KurzweilAI, he pushes the boundary of long-term thinking about humanity’s survival out to the edge … and beyond. — Ed.

It isn’t enough just to plan for two or 20, or even the fabled Chinese 100 year periods. We need to be thinking and planning on the order of billions of years. Our civilization needs inter-generational plans and goals that span as far out as we can forecast significant events.
