Look Up February 2018 by Royal Observatory Greenwich published on 2018-01-25T12:27:11Z Royal Observatory Astronomers Dhara and Greg take you through what to see in the night sky during the month of February in our family friendly Look Up! podcast. Each month the astronomers pick their favourite astro’ news story – this month they chat about the first time details on a star's surface have been observed - until now, our Sun in the only star we have ever seen details on. The second story is all about a newly proposed definition for a planet which includes setting an upper limit to its mass. Vote for your favourite on Twitter: @ROGAstronomers #ROGSchools.
