Mimas, a Middle-Sized Icy Moon of Saturn, Could Harbour a Subsurface Ocean

An international team of researchers from France, the United States, and Belgium, including Attilio Rivoldini of the Royal Observatory of Belgium has measured the rotation of Mimas by studying data provided by the spacecraft Cassini orbiting Saturn. Their study suggests its cratered surface hides one of two intriguing possibilities: either the moon’s frozen core is shaped something like a football, [...]

Strong Solar Flare

On 10 September, the Sun produced a powerful X-class (“eXtreme”) solar flare. The consequences for Belgium are limited for the time being. High-frequency (HF) radio-communication at the Earth’s dayside (USA and South-America) was probably disturbed. A plasma cloud was ejected into space and is expected to arrive at Earth on 12 September around 21:00UT (+/- 12 uur).
