Star atlases are an essential tool for use in amateur astronomy. In this hangout, we’ll discuss the various forms of star atlases, and talk with Wil Tirion, a long-time stellar cartographer (uranographer) whose maps have been ubiquitous in astronomy.

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
Think about it: Hubble is down to one gyro, maybe two; Kepler is in safe mode; and today, the Chandra X-ray telescope went into safe mode; Spitzer has run out of coolant but still doing science – our fleet of space telescopes is getting older what are we replacing them with?
Bad news I’m afraid for the venerable Hubble Space Telescope. Hubble has been placed in safe mode as two of it’s critical gyros used for pointing have failed.
While imaging the Andromeda Galaxy, the Spitzer Space Telescope uncoverd a never-before-seen hole, the result of a collision with a nearby dwarf galaxy, in the Andromeda Galaxy.
