This artist's concept depicts Kepler-186f, the first validated Earth-size planet to orbit a distant star in the habitable zone—a range of distance from a star where liquid water might pool on the planet's surface.

Here's a good sign for alien hunters: More than 300 million worlds with similar conditions to Earth are scattered throughout the Milky Way galaxy. A new analysis concludes that roughly half of the galaxy's sunlike stars host rocky worlds in habitable zones where liquid water could pool or flow over the planets' surfaces.
This may worth something:
Two planets found orbiting a red dwarf
One instrument, with which it is possible to study red dwarfs and their planets closely, is the Mexico-based SAINT-EX telescope, co-operated by the NCCR PlanetS. SAINT-EX is an acronym that stands for Search And characterIsatioN of Transiting EXoplanets. The project has been named in honor of Antoine de Saint-Exupéry (Saint-Ex), the famous writer, poet and aviator.
The SAINT-EX Observatory is a fully robotic facility hosting a 1-meter telescope. It is equipped with instrumentation specifically suited to enable high-precision detection of small planets orbiting cool stars. Now, this specialization pays off: earlier this year, the telescope was able to detect two exoplanets orbiting the star TOI-1266, located around 120 light years from Earth.
LOONA Takes Orbits Behind the Scenes of EP "[12:00]": Exclusive | Teen Vogue
The album's lead single, "Why Not?," is an anthem for that vision and encourages listeners to pursue what makes them happy and revel in their uniqueness. " Follow your mood, follow your feeling, why not? Do it!" the lyrics exclaim. "Dance all night... Don't worry about what others think ." It's a sentiment that LOONA has expressed throughout their career , and it has earned them a loyal legion of fans, called Orbits — and a Billboard 200 chart debut with [12:00] .
In this exclusive video, LOONA takes Teen Vogue behind the scenes as they prepared to release [12:00] . We followed them to choreography rehearsal ("I am inviting you guys to our practice room!" proclaims HeeJin warmly) and heard from the group about what they've been thinking about lately — including why JinSoul thinks that "spending time together [to rehearse] has decreased and spending time on ourselves has increased."
How the Space Station Became a Base to Launch Humanity's Future - The New York Times
Once derided as a poster child for government waste, the outpost in orbit is now seen as a linchpin for future economic activity in space.

Much of the work on Dr. Chiao's flight was done outside the space station, during spacewalks. But the astronauts also got to go inside briefly.
It was a runt of a space station then. The habitable portion consisted of just three modules, not the 16 orbiting today. But it was ready for people to move in.
Not to change the topic here:

"Red dwarfs are the most numerous types of stars, and their small sizes make them favorable for studying orbiting planets. Astronomers are interested in understanding what the prospects are for habitable planets around red dwarfs," said Kevin France of University of Colorado in Boulder who led the study. "Barnard's Star is a great case study for learning about what happens around older red dwarfs in particular."
Elon Musk, SpaceX aims to make fast satellite internet through Starlink network
Typical satellite internet services offer slow speeds and high-latency because of the limitations of traditional satellite networks that are far away from the earth.
The more important spec being publicized is their much lower latency of 20-40 millisecond vs. the typical 500-700 milliseconds from existing satellite internet services.
Think of low latency as fewer stoplights on a trip through town. Driving a 200 mph Ferrari that has to constantly stop at stoplights will take longer than a smart car that takes an alternative route with far fewer stoplights.

Shadow Satellite
Kepler-1625b
Discovered by: Kepler
Discovered: 2016
Distance from Earth: ~8000 light-years
Mass: ~11 Jupiter masses
Radius: ~0.6 Jupiter radii
Surface climate: Unpleasantly warm
Habitability for humans: No.

Today, we go to the neighborhood of a yellow star approximately 2500 parsecs in the direction of the constellation Cygnus.
It's almost fitting that, for a star that's inflated in size, a planet that orbits it at roughly around the distance of Earth is similarly large and blown-up. Kepler-1625b, the only confirmed planet in this star system, is a gas giant.
Musk: SpaceX's Starlink has enough orbiting satellites for public beta - Business Insider
Elon Musk's goal of beaming high-speed internet to remote parts of Earth using orbiting satellites just got a step closer to reality.
"Once these satellites reach their target position, we will be able to roll out a fairly wide public beta in northern US & hopefully southern Canada," he tweeted after the launch.

Musk did not say exactly when the satellites were expected to reach their "target position," and Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, told Ars Technica that they might not be in place until February.
