Proxima Centauri B

Astronomers have confirmed a small exoplanet orbiting Barnard's star, the closest single star to our sun. There are hints of at least 3 more planets as well. The post Barnard's Star has 1 planet, maybe more, at last! first appeared on EarthSky.

Could there be more?

At just six light-years from Earth, Barnard's star is close by and has long been of interest to researchers searching for exoplanets. Now, they've found one.

Astronomers are especially interested in the habitability of these kinds of planets, which always face their star with the same side, because they are...

Astronomers from NASA and the University of Washington have estimated total internal heating rates and depths to possible subsurface oceans for 17 planets that may be cold ocean planets.

Wolf 1069b is the sixth closest Earth-mass exoplanet situated in the conservative habitable zone of its parent star, after Proxima Centauri b, Gliese 1061d, Teegarden's Star c, and Gliese 1002b and c.

The newly discovered Wolf 1069 b is an Earth-mass exoplanet in the habitable zone of its star.

Driven by his lifelong passion for science and his belief that the work of great scientists enriches us all, Yuri Milner has founded and invested millions into the Breakthrough Foundation, which oversees various projects that champion innovative research, reward established and emerging scientists, and further humanity's search for intelligent extraterrestrial life.

Space travel can be agonizingly slow: For example, the New Horizons probe took almost 10 years to reach Pluto. Traveling to Proxima Centauri b, the closest habitable planet to Earth, would require thousands of years with even the biggest rockets. Now, researchers calculate in ACS' Nano Letters that low-power lasers on Earth could launch and maneuver small probes equipped with silicon or boron nitride sails,…

Proxima d, which orbits the star nearest our Sun, is estimated to be only a quarter of Earth's mass

Astronomers believe they have discovered a new world orbiting Proxima Centauri. Proxima Centauri is the closest star to our Solar System. It's located...

Could we support life somewhere else in our universe? Researchers have identified some exoplanets that are promising.

How can machine learning help astronomers find Earth-like exoplanets? This is what a new study hopes to address as a team of international researchers investigated how a novel neural network-based algorithm could be used to detect Earth-like exoplanets using data from the radial velocity (RV) detection method.

Through its NIAC program, NASA has awarded funding to 13 innovative space technology concepts that could shape future missions to Venus, Mars and worlds...

Proxima Centauri is the nearest star to our sun at 4.22 light-years away. It's home to at least 2 planets and has massive solar flares. The post Proxima Centauri, the closest star to our sun first appeared on EarthSky.

He hasn't even made it to Mars yet, and SpaceX CEO Elon Musk already has his eyes on a new exoplanet to colonize: Proxima Centauri B.

NASA scientists are using reserve power to keep Voyager 1 and 2 in operation.

Alpha Centauri is our closest stellar neighbor, a binary star system located just 4.376 light-years away. Despite its proximity, repeated astronomical surveys have failed to find hard evidence of extrasolar planets in this system. Part of the problem is that the system consists of two stars orbiting each other, which makes detecting exoplanets through the two most popular methods very challenging. In 2019,…

Humanity is compelled, sometimes against our better judgment, to push against boundaries and carve out new horizons. Every mountain range, apparently...
