To move long distances quickly, the astronauts found it was easier to make small "kangaroo hops" with both legs. They would literally propel themselves above the surface before they made gentle falls to the ground. Machines that ... more MESSENGER Gets Closest Look At Solar-Flare Neutrons ![]() On Dec. 31, 2007, the Sun awoke from the relatively quiescent period between Solar Cycles 23 and 24 to produce a solar flare that spewed high-energy neutrons into interplanetary space. The Neutron Spectrometer flying aboard NASA's MESSENGER spacecraft recorded the event, giving scientists a first-ever, up-close look at neutron production from a solar flare. In fact, it was the first time ... more Astronomy Question Of The Week: What Happens When Stars Play Hide-And-Seek ![]() Astronomers know the answer and would therefore have been able to answer the One-Million-Euro question in the 250th episode of Gunter Jauch's hit TV show 'Wer wird Million�r?'
