It's here. The image I've been waiting for. MIRI's view of the Pillars of Creation. Words fail me. The light has been filtered to emphasise the dust rather than make it translucent, which you might have expected at mid-infrared wavelengths. Incredible.

This is a big moment for me, personally. I've always considered myself to be a bit of a "water carrier" in science journalism, someone who worked hard to get the facts right without being a star writer. Today, a little sunshine falls on the journeyman. Thank you

Most people know that the magnetic north pole is not at the geographic north pole. It's drifting away from Canada towards Russia at a rate of 55km/yr. BUT, this year, the magnetic pole is closest to the geo pole. A separation of just 390km.
