Pioneer 10 and 11
(

)
(Preview)
The Pioneer 10 and 11 spacecraft exhibited an `error` in their trajectories that `drag` them 8.74e-8 cm/sec/sec back towards the sun, after they had ventured passed a distance of 20 AU. This anomalous acceleration has come to be referred to as the Pioneer Effect.
If this represen...

Galaxy haloes
(Preview)
Astronomers using ESA's XMM-Newton observatory have found very hot gaseous haloes around a multitude of spiral galaxies similar to our Milky Way galaxy. These 'ghost-like' veils have been suspected for decades but remained elusive until now.
Galaxy 'haloes' are often seen in so-called 's...
