OK, our blog posting is a little behind. What can we say; it’s a busy time of year. But there is big news in longer-wavelength astronomy: the ALMA telescope had its official inauguration 10 days ago. It is not quite complete yet: the last 7 of 66 antennas are still being tested. But it is taking data and some science results have even appeared. Hooray!

The European Southern Observatory has a video (which seems to be mercifully free of speeches) if you want to know more.
