See the old Moon join a dawn planetary parade, 18–19 March

If you’re an early riser in the British Isles, let the waning crescent Moon be your guide to three naked-eye planets – Mars, Jupiter and Saturn – at dawn on 18 and 19 March 2020. This celestial conjunction occurs in the constellation of Sagittarius where you can see all four Solar System bodies within the span of a fist at arm’s length. Look for attractive binocular conjunctions too.

The pair lie just 2.2 degrees apart against the constellation backdrop of Aries, simultaneously visible in typical 10×50 binoculars.

Adding a new dimension to the early chemistry of the solar system

The study has given new insights into the chemical composition of the dust grains that formed in the solar system 4.5 billion years ago.
