Dagnello Astronomers around the world have spotted one of the most powerful stellar flares ever seen in our galaxy exploding off Proxima Centauri, our nearest neighboring star.  "The star went from normal to 14,000 times brighter when seen in ultraviolet wavelengt...

April 23, 2021 Astronomers saw Proxima Centauri – the star nearest our sun – emit a flare, or burst of radiation, 100 times more powerful than flares from our sun. They said Proxima’s flare ranks as one of the most violent seen on a solitary star anywhere in the galaxy.

But this flare was 100 times more ...

The closest star to Earth is Proxima Centauri. It is about 4.25 light-years away, or about 25 trillion miles (40 trillion km). The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of 450,000 mph. It would take just 20 seconds to go from Los Angeles to New York City at that speed, but it would take the solar probe about 6,633 years to reach Earth’s nearest neighboring solar system. If humanity ever wants to travel easily between stars, people will need to g...

"But the catch is that theyre way more active than our sun. "They flare much more frequently and intensely." Our sun doesnt release many powerful flares; they occur only a few times during each 11-year solar cycle. However, these flares are much more common on Proxima Centauri. During their observation campaign, the astronomers recorded many other flares produced by the star over the course of 40 hours. "Proxima Centauris planets are getting hit by something like this not once in a century, but...

What is an exoplanet? April 22, 2021 at 12:07 pm Exoplanets are planets orbiting distant stars beyond our Solar System, and today astronomers calculate that for every star we can see in the night sky, there is on average at least one exoplanet in orbit around it. Advertisement The concept of exoplanets is hardly new: as far back as 1584, Italian philosopher Giordano Bruno suggested space was filled by “an infinity of worlds of the same kind as our own”. An illustration depicting the varie...

The closest star to the Sun, Proxima Centauri, has released a record-breaking flare – and thanks to a network of nine telescopes on the ground and in space, astronomers were able to capture the extreme event. The discovery is published in The Astrophysical Journal Letters. Proxima Centauri is about one-eighth the mass of the Sun and is classified as a red dwarf. Stars are prone to the occasional flare, but the one seen by five of the nine telescopes on May 1, 2019, was among the most extreme ...

Record-breaking flare spotted on Suns nearest neighbour Record-breaking flare spotted on Suns nearest neighbour Last Updated: Thu, Apr 22nd, 2021, 16:41:40hrs New York, April 22 (IANS) Scientists have spotted the largest flare ever recorded from the suns nearest neighbour, the star Proxima Centauri. Proxima Centauri is a small but mighty star. It sits just four light-years or more than 20 trillion miles from our own Sun and hosts at least two planets, one of which may look something like Earth....
