Great day at DIAS Dunsink Observatory talking future space missions … and checking out sunspots with the historic Grubb Refractor. Not a bad way to spend my birthday.

First images from the Square Kilometre Array Low Frequency (SKA-Low)!
Taken with only 1,024 of the planned 131,072 antennas, and it's already looking good :)

Spotted this rolled up on a shelf in Birr Castle today: “Observations of the radiation of heat from the Moon Dec 1868 - Apr 1869”.
The 4th Earl made a 3 foot telescope and thermopile to measure lunar heat. Pretty amazing.
