A new analysis of Apollo moon samples reveals insight into the history of the lunar magnetic field.
Radio astronomy offers scientists a means of observing the "unseen" Universe, where a wide range of natural phenomena take place that optical telescopes cannot observe. This is the purpose behind the Low-Frequency Array (LOFAR), a massive radio telescope with stations all across Europe. It is the largest and most sensitive radio telescope in the world, operating at low frequencies (10–240 MHz). After ten years of surveying the sky, the LOFAR Collaboration has produced the most detailed radio map of the Universe ever made.
