An artist's impression of a flare from Proxima Centauri, modeled after the loops of glowing hot gas seen in the largest solar flares. Exoplanet Proxima b is shown in the foreground. Proxima b orbits ...

The closest star to Earth, Proxima Centauri (PC), is still about 8000 times further away from us than Pluto. Propelling a probe to PC will require a much higher cruising speed than we can currently ...

Solar sails may become one of the most revolutionary propulsion systems ever developed. Instead of fuel, these spacecraft use ...

Proxima Centauri b is the closest exoplanet to Earth. It is an Earth-mass world right in the habitable zone of a red dwarf star just 4 light-years from Earth. It receives about 65% of the energy Earth ...

It’s one of the most fascinating questions when it comes to our exploration of space: is there other life out there? With countless space scientists uniting in explaining to us that – given the vast ...

The ALMA Observatory in Chile has detected dust around the closest star to the Solar System, Proxima Centauri. These new observations reveal the glow coming from cold dust in a region between one to ...

In August astronomers announced that the nearby star Proxima Centauri hosts an Earth-sized planet (called Proxima b) in its habitable zone. At first glance, Proxima Centauri seems nothing like our Sun ...

Alpha Centauri, one of the two "Pointer Stars" that help stargazers find the Southern Cross in the Southern Hemisphere, may have a planet in orbit around it. If it does, the Webb Telescope will find ...

What can star variability—changes in a star's brightness over time—teach astronomers about exoplanet habitability? This is what a recent study accepted for publication in The Astronomical Journal ...

The existence of a potentially habitable planet orbiting our closest neighbor, the red dwarf Proxima Centauri, is both an extremely exciting event and sort of "more of the same." While Proxima b is ...
