Andromeda in High Resolution

This afternoon I gave three hours of lectures on the trot, so I’m now feeling more than a little knackered. Before I head home for an early night, though, I thought I’d share this amazing video produced by the Panchromatic Hubble Andromeda Survey (or PHAT, for short), which is a Hubble Space Telescope (HST) Multi-cycle program to map roughly a third of the star-forming disk of the Andromeda Nebula (M31), using 6 filters covering from the ultraviolet through the near infrared. With HST’s resolution and sensitivity, the disk of M31 is resolved into more than 100 million stars. The combination of scale and detail is simply jaw-dropping. Hat’s off to the PHAT team!

“She can’t be unhappy,” you said,
“The smiles are like stars in her eyes,
And her laughter is thistledown
Around her low replies.”
“Is she unhappy?” you said–
But who has ever known
Another’s heartbreak–
All he can know is his own;
And she seems hushed to me,
As hushed as though
Her heart were a hunter’s fire
Smothered in snow.

by Sara Teasdale (1885-1933)
