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 |

The gas composition of a planet's atmosphere generally determines how much heat gets trapped in the atmosphere. For the dwarf planet Pluto, however, the predicted temperature based on the composition of its atmosphere was much higher than actual measurements taken by NASA's New Horizons spacecraft in 2015.

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.

In a unique experiment, researchers have clocked how long it takes for an electron to be emitted from an atom. The result is 0.000 000 000 000 000 02 seconds, or 20 billionths of a billionth of a second. The researchers' stopwatch consists of extremely short laser pulses. Hopefully, the results will help to provide new insights into some of the most fundamental processes in nature.
