Can a magnetic sail slow down an interstellar probe



Frankfurt, Germany (SPX) Nov 20, 2017
With a miniaturised space probe capable of being accelerated to a quarter of the speed of light, we could reach Alpha Centauri, our nearest star, in 20 to 50 years. However, without a mechanism to slow it down, the space probe could only collect data from the star and its planets as it zoomed past. A theoretical physicist at Goethe University Frankfurt has now examined whether interstellar spacecraft can be decelerated using "magnetic sails". For a long time, the idea of sending unmanned spa ... read more

Unlucky dinosaurs: Scientists say asteroid had 13 percent chance of triggering extinction

Neutron star with strong magnetic field may still launch jets

An international team of astronomers led by the University of Amsterdam (The Netherlands) suspects that neutron stars with a strong magnetic field can still launch so-called jets. Since the 1980s, it was thought that strong magnetic fields inhibit the formation of these plasma streams. But observations with more advanced telescopes indicate jet-like radiation. The astronomers publish their findi ... more

Hopefully, the results will help to provide new insights into some of the most fundamental processes in nature. Researc ... more
