Astronomers using the ALMA telescope high in the Chilean Andes have observed a star forming where planets are normally thought to be born. Please join Tony Darnell as he discusses these observations with Dr. John Ilee from the University of Leeds.

Did you know there is an effort underway to actually see the event horizon of a black hole? Let’s learn about one of the most amazing astronomy endeavours ever with @DeepAstronomy

Tony Darnell from @Deep Astronomy discuss about Astronomy outreach with Ian Lauer. #365DaysOfAstro

What gear do professional astronomers use that is available commercially?

Join @deepastronomy today talk about astronomy at the European Southern Observatory (@ESO) more at #365daysOfAstro
