Despite being the very first candidate planet discovered by our Kepler Mission, Kepler-1658b had a rocky road to confirmation

Posted by in category: space

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

Exploring China’s latest space ambitions

Posted by in categories: solar power, space, sustainability

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.

Fifty Billion Planets In Our Milky Way Galaxy Are Likely To Be Free Floaters, Says New Study

Posted by in categories: evolution, space

Homeless free-floating planets are likely to be rampant within the Milky Way, says new study. Young, dense loose clusters of stars are pretty raucous places early in their evolution.

Beautiful First Image Captured by a new telescope in the Chilean desert

Posted by in categories: robotics/AI, space

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.

Vast underground ocean discovered on Jupiter’s largest moon

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.
