Quickest we could visit another star is 69 years – here’s how

Of all the stars in the sky, you might assume the closest to the sun would be the easiest to visit. But this may not be the case.

René Heller at the Max Planck Institute for Solar System Research in Göttingen, Germany, says we could reach and orbit Sirius, the brightest star in our night sky, in just 69 years. This is despite the fact that it is twice as far away as our nearest stars in the Alpha Centauri system, which would take at least 90 years to reach.

Astronomers spot two stars colliding, creating stellar ‘fireworks’ 1,500 light years away

The debris left behind after stars were born in dramatic explosions has been caught on camera.

Using the Atacama Large Millimeter/submillimeter Array (Alma), a group of astronomers has studied the aftermath from an explosive event when two young stars grazed past each other.

Stars form when huge clouds of dust and gas, known as protostars, collapse under their own weight. Thousands of years ago, two protostars in the Orion Molecular Cloud 1 (OMC-1), 1,500 light years away, orbited close to one another.
