The number of galaxies out there? Yep, something around that figure... trillion of galaxies! A very sleepy and astro-jet lagged astrophysicist Ángel López-Sánchez and young but very wise astronomer Kirsten Bank jump into the realm of galaxies! They define their basic properties and classification and discuss the names given in the famous "Hubble Tuning Fork". The "What's Up!" section is dedicated to our all-time favourite nearby dwarf galaxy: the Large Magellanic Cloud. And they also talk about supernova explosions, those coming from the death of massive stars: SN 1987A and SN2016gkg. The latest supernova was discovered by an amateur astronomer, who saw in real time how the light of the supernova appeared in the images he was taking with his new camera. No feedback today (did we say Ángel was very sleepy?) but more to come soon!
