Proxima centauri

An enigmatic radio signal from the direction of Proxima Centauri has set the internet ablaze with rumor and speculation. It's likely nothing, but what we know is intriguing.

What makes this recent discovery, dubbed Proxima b, so particularly exciting?

Alpha Centauri is a triple star system located roughly 4.3 light-years from Earth. It’s the closest star system to the Sun and consists of three stars – Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Both Alpha Centauri A and B are Sun-like stars (class G and K respectively) while Proxima Centauri is a relatively dim red dwarf star. To the naked eye, these stars appear as one, shining bright in the night sky. Only two exoplanets have been discovered in this enthralling star…

Is anyone else as fantasized with outer space? I love hearing the latest information about new discoveries, planets and galaxies! There are more than 4,000 exoplanets that have been discovered, but many are too far

Alpha Centauri °•○ Alpha Centauri (α Centauri, α Cen, or Alpha Cen) is a triple star system in the southern constellation of Centaurus. It consists of three stars: Rigil Kentaurus (α Centauri A), Toliman (α Centauri B), and Proxima Centauri (α Centauri C).Proxima Centauri is the closest star to the Sun at 4.2465 light-years (1.3020 pc). α Centauri A and B are Sun-like stars (class G and K, respectively) that together form the binary star system α Centauri AB. To the naked eye, these two…

A few months ago Proxima Centauri b, an exoplanet in the constellation of Centaurus located “only” 4.22 light-years from Earth, got a lot of attention, since it orbits its sun within th…

The newly discovered Proxima b orbits Proxima Centauri, the nearest star beyond our solar system. Proxima b might host water and even life.

Since the beginning of human history, people have understood that the sun is a central part of life as we know it. It's importance to countless mythological and cosmological systems across the globe is a testament to this. But as our understand of it matured, we came to learn that the sun was here long before us, and will be here long after we're gone. Having formed roughly 4.6 billion years ago, our sun began its life roughly 40 million years before our Earth had formed.

The superflare made Proxima Centauri 68 times brighter than usual and may have exposed any life on its orbiting Proxima b planet to lethal levels of ultraviolet radiation, according to the study.
