A new model has been developed to simulate interstellar activity within our solar system and the nearby Alpha Centauri system ...

Using ALMA, astronomers discovered that Proxima Centauri produces frequent, high-energy millimeter-wavelength flares that could significantly alter or strip the atmospheres of its habitable-zone ...

Alpha Centauri, the closest star system to our Solar System, is located approximately 4.37 light-years away from Earth in the constellation Centaurus. It comprises three stars: Alpha Centauri A ...

After the Alpha Centauri system, the next closest is Barnard ... Research published in August 2024 finally confirmed the presence of a planet orbiting Barnard’s Star, dubbed Barnard’s ...

Get Instant Summarized Text (Gist) Proxima Centauri, an active M dwarf star, exhibits intense flare activity in radio and millimeter wavelengths, as observed by ALMA. These flares, ranging from 10 ...

For context, the closest star to our solar system is Alpha Centauri, which is 4.37 light-years from Earth. That means a spacecraft traveling at the speed of light would take 4.37 years to get ...

It’s twice as massive as the Sun. Alpha Centauri is a triple star system, the third brightest and closest star system to Earth at 4.37 light-years away. Arcturus, the fourth brightest star ...

Proxima Centauri, a star four light-years from the ... potentially obliterating the planet’s air. Not having an atmosphere, which traps important gases like oxygen and water vapor, may render ...

Their conclusion was clear: with only ten hours of observation, the ELT could likely identify atmospheric biosignatures on an Earth-like planet around Proxima Centauri. For gas giants, meaningful ...

But the study authors, and other experts, remain cautious and have not declared a definitive discovery of life beyond our planet. Using the James Webb Space Telescope, the team detected chemical ...

Astronomers pointed the powerful James Webb Space Telescope at planetary nebula NGC 1514, where a star is shedding copious amounts of gas into the universe as it gradually exhausts its fuel and ...
