Proxima Centauri dust belts, illustration
Proxima Centauri dust belts. Computer illustration showing newly discovered belts of dust around the star Proxima Centauri. Lying only around 4.25 light years from the Sun, Proxima Centauri (Alpha Centauri C) is the closest star to the Solar System. Observations by the Atacama Large Millimeter Array (ALMA) revealed the glow coming from cold dust in a region between one to four times as far from Proxima Centauri as the Earth is from the Sun. The data also hint at the presence of an even cooler outer dust belt and indicate the presence of an elaborate planetary system. These structures are similar to the much larger belts in the Solar System and are also expected to be made from particles of rock and ice that failed to form planets. (Not to scale)
