Today I learnt that there are two instruments called #HiRISE in operation in #space related domains:

• The High Resolution Imaging Science Experiment onboard #NASA's Mars Reconnaissance Orbiter (#MRO): uahirise.org/epo/about/, and
• The High-Resolution Imaging and Spectroscopy of Exoplanets instrument at #ESO's #VLT facility in #Chile: cnrs.fr/en/press/first-light-h

Image of the HiRISE fibre injection module, of the latter, which I didn't know existed.

This is one of my favourite landscape photos from the trip to Chile because it's a great example of the dramatic, other-worldly landscape of the Atacama Desert, while also showing all the major components of Paranal Observatory.

It's a moderately telephoto (70 mm on APS-C) view towards Paranal Observatory from the Extremely Large Telescope construction site on Cerro Armazones, about 20 km distant. In the centre is Cerro Paranal itself, with the cluster of telescopes that make up the Very Large Telescope facility. Over to the right is a lower peak with a smaller telescope building, that is VISTA. To the lower left of the VISTA peak are some smaller white structures, that's the NGTS Observatory and the four SPECULOOS telescopes. Finally over on the left there are more white structures, those are the various utility and office buildings of the Paranal Observatory base camp.

Full resolution versions of this, and other landscape photos, here: drhotdog.smugmug.com/Astronomy

I edited a couple of my own photos into a size comparison of ESO's Very Large Telescope(s) and Extremely Large Telescope. The top is the VLT photographed from the ELT (in the middle of the day) and the bottom photo is the ELT photographed from the VLT (at sunset). Same distance (20 km), same camera, same lens, so the scale of the two photos should be identical.

The source photos (and more) can be found here: drhotdog.smugmug.com/Astronomy

Edit: I removed the ELT scale bar because of a couple of issues. First, because the photo of the ELT was taken from a lower altitude part of the ELT building is hidden behind the near side of the flattened mountaintop. Second, the ELT dome doors have not yet been installed so the current structure is, I think, less than 80 metres tall.

I've started to sift through all the photos I took in Chile, picking out and reprocessing the good ones, and uploading them to web galleries here: drhotdog.smugmug.com/Astronomy

Web galleries? Yes, I know, it's very 2010 of me. It's also the only way to share photos in quantity without having all the detail squeezed out of them by heavy re-compression.

Here's an example pic of the VISTA telescope at sunset, as seen from the VLT Platform. The VISTA telescope was built to perform an all sky imaging survey in the near infrared, but with that complete the infrared camera is being replaced with a visible wavelength spectroscopic survey instrument, 4MOST (4most.eu/).

I'm back home in Sydney now, but I reckon I can manage a few more posts about the trip to Paranal Observatory.

Here's a photo of the MAVIS delegation on the Very Large Telescope platform, taken by Juan Beltran Peña. If you search for his name you'll find his Instagram profile, with lots of amazing photos of telescopes, the night sky, and other things.

These are two of the four lasers in question, mounted on the side of VLT Unit Telescope 4. They are the black objects labelled LGSU1 and LGSU4. LGSU2 and LGSU3 are mounted in the corresponding positions on the far side of the telescope. Each of the four laser guide star units emits 22 Watts of continuous wave optical power at 589 nm.

Below the lasers you can see the 8.2 metre diameter primary mirror almost side on, and in the centre of the structure above you can see the small Deformable Secondary Mirror.

There are two exciting things about today.

1. There is now help-yourself ice cream in the Paranal Observatory canteen.

2. The maintenance on the 4 Laser Guide Star Facility has been completed, so we will all be going up to the Platform after dinner to get photos of the sky lasers from close range. This is just in time, as tonight is our last night here.
