(CNN) Astronomers have discovered two super-Earth exoplanets orbiting a star 11 light-years away from Earth, according to a new study. There is also a potential third planet orbiting a bit further away from the star, according to the researchers.

Quantum entanglement demonstrated on orbiting CubeSat | University of Strathclyde
In a critical step toward creating a global quantum communications network, researchers have generated and detected quantum entanglement onboard a CubeSat nanosatellite weighing less than 2.6 kg and orbiting the Earth.
The University of Strathclyde is involved in an international team which has demonstrated that their miniaturised source of quantum entanglement can operate successfully in space aboard a low-resource, cost-effective CubeSat that is smaller than a shoebox. CubeSats are a standard type of nanosatellite made of multiples of 10 cm × 10 cm × 10 cm cubic units.

Space is hard, as the saying goes. How hard? Take this scenario: your satellite is orbiting at the speed of 27,000 kilometres per hour when it stops working.
It's still orbiting just no longer functioning. Unlike a car stuck in a ditch, you can't see what's happened to it. You are at the mercy of instruments.

6 exomoons orbiting alien worlds? Well, it's complicated. | Space
Scientists have spotted thousands of worlds in other solar systems, so many that exoplanets have become a dime a dozen. But in our neighborhood, three quarters of planets have at least one moon , and no such object in other systems has been confidently discovered so far — such worlds are just too small and far away.
Now, a new paper points to six exoplanets where wobbles in their data may be caused by exomoons . But that doesn't necessarily guarantee the presence of such moons, and there's no way right now for scientists to determine the real details of the situation. Those are big challenges for any research to overcome.
Many things are taking place:
Scientists Have Demonstrated Quantum Entanglement on a Tiny Satellite Orbiting Earth
In the strange field of quantum physics, quantum entanglement – what Einstein called "spooky action at a distance" – stands out as one of the most intriguing phenomena. And now scientists just managed to successfully demonstrate it again, this time onboard a CubeSat satellite orbiting Earth.
While a quantum internet is still some way off, if we want to make it work, it's going to require something other than optical fibres.
So scientists are experimenting with quantum entanglement in all kinds of new and improved ways – including out in space.
Quantum entanglement demonstrated aboard orbiting CubeSat: Advance poised to enable
In a critical step toward creating a global quantum communications network, researchers have generated and detected quantum entanglement onboard a CubeSat nanosatellite weighing less than 2.6 kilograms and orbiting the Earth.
"In the future, our system could be part of a global quantum network transmitting quantum signals to receivers on Earth or on other spacecraft," said lead author Aitor Villar from the Centre for Quantum Technologies at the National University of Singapore.

A baby Jupiter was just spotted orbiting a nearby star – BGR
Our solar system is packed with a variety of planets, and we know more about some of them than we do others. Earth, of course, we know the most about, followed by Mars. Some of the more mysterious planets include Jupiter, which is a massive orb of mostly gas that seems to collect moons like it’s a profession .
Much of our time spent studying Jupiter has been focused on its massive storms and towering clouds that stretch deep into the planet. We don’t know a lot about how it formed, but by spotting young Jupiter-like worlds elsewhere in space we can get a better idea. A newly-discovered exoplanet called HIP 67522 b fits the bill perfectly, and it’s giving astronomers a lot to think about.
