Astronomer explains plan to send tiny spaceships to Alpha Centauri

"A group of astronomers and technology entrepreneurs has announced an audacious plan to send a fleet of tiny spaceships traveling at a fifth the speed of light to the nearest star, Alpha Centauri. 

"The plan would see humankind leap out of the solar system with the aid of an ultralight vessel made of what are essentially cellphone components and a thin, reflective light sail propelled by an enormous array of Earth-based lasers.

Fast Radio Burst "Afterglow" Was Actually a Flickering Black Hole

Fast Radio Burst "Afterglow" Was Actually a Flickering Black Hole

April 4, 2016
Last February a team of astronomers reported detecting an afterglow from a mysterious event called a fast radio burst, which would pinpoint the precise position of the burst's origin, a longstanding goal in studies of these mysterious events. These findings were quickly called into question by follow-up observations. New research by Harvard astronomers Peter Williams and Edo Berger shows that the radio emission believed to be an afterglow actually originated from a distant galaxy's core and was unassociated with the fast radio burst.
Tiny, Ultracool Star is Super Stormy

Tiny, Ultracool Star is Super Stormy

"Our Sun is a relatively quiet star that only occasionally releases solar flares or blasts of energetic particles that threaten satellites and power grids. You might think that smaller, cooler stars would be even more sedate. However, astronomers have now identified a tiny star with a monstrous temper. It shows evidence of much stronger flares than anything our Sun produces. If similar stars prove to be just as stormy, then potentially habitable planets orbiting them are likely to be much less hospitable than previously thought"

Could Alien Life Spread 'Like a Virus' to the Stars?

Could Alien Life Spread 'Like a Virus' to the Stars?

August 31, 2015
"As astronomical techniques become more advanced, a team of astrophysicists think they will be able to not only detect the signatures of alien life in exoplanetary atmospheres, but also track its relentless spread throughout the galaxy.

The research, headed by Henry Lin of the Harvard-Smithsonian Center for Astrophysics (CfA), assumes that this feat may be possible in a generation or so and that the hypothesis of panspermia may act as the delivery system for alien biology to hop from one star system to another."
