First in person conference in a long time and first educational conference ever! Super excited to be at . Looking forward to talk about structured student-led research projects.
Loving my conference straps, btw ☺️

I'm sure you love astronomical images taken with professional telescopes. But do you know what it takes to actually make them? You'll be surprised by how many people are involved!

I just wrote an article explaining the whole process, from the moment an astronomer has an idea to when you see the final result.

Check it out:


Normally I point my camera up towards things in space (galaxies, nebulae, stars…). This time I had the rare opportunity of pointing it to someone who has been to space!

How did your week go? Mine is finishing quite well 😁. Delighted to have had the opportunity of meeting Commander Chris Hadfield. A really inspiring moment. He was amazing with us, very generous with his time answering all our questions

This happened today!! 😍
The amazing EIRSAT-1 team invited me to help for a few minutes building the final version of Ireland’s first satellite. What an incredible opportunity!

These are NGC5426 and NGC5427, collectively known as Arp271, a pair of interacting spiral galaxies located about 130 million lightyears away.

I took this image back in 2018 with VIMOS, an instrument at ESO's Very Large Telescope in Chile. I was the Instrument Scientist, and that night we were decommissioning the instrument to make room for a new one, so I decided to take one last farewell image to celebrate all the cool science done with this instrument over the years.

Today I was invited to join the EIRSAT-1 team to their clean room to help tiny bit while they continue working towards building the final version of the satellite. We are building Ireland’s first satellite! A cubesat the size of a shoebox that will monitor the gamma-ray sky with novel technollogy developed here at UCD.
Exciting times!

Are you using Mastodon through a computer?

Do you wish there was a multi-column TweetDeck-style interface?

There is! It's called the "advanced web interface" and you can activate it any time you want. It lets you add many specialised columns, subscribe to hashtags and all kinds of stuff suited to large wide displays.

Log into the website, go to Preferences > Enable Advanced Web Interface, tick the box and click "Save Changes".

(To restore the default single column interface, do the same thing but untick the box instead.)

This used to be the default interface on Mastodon, and very old articles about the platform will have screenshots of the multicolumn interface.

I was told today that our programme with the Calar Alto 2.2m telescope (big dome on the right) was renewed for another semester with really positive comments from the time allocation committee panel. Looking forward to keep searching for new GRB-SNe connections!

Late afternoon at Devil's Tanyard, Jezero Crater, #Mars.

Yep, that's a -10° slope correction for the NAVCAM, which is what this mosaic was meant to show, not the sunset 🥴

No sinking sunsets here 😎

I love when Mars shows off its clouds on the terminator!

This is Sagittarius A* best-bet model video, the massive black hole at the center of our Galaxy.

"The video shows a high-res simulation of one of the best-bet theoretical models of Sgr A* across about 28 hours."

Since we're all excited about the image of Sagittarius A*, here's a different view of the central regions of our galaxy.

In January the MeerKAT telescope in South Africa released a stunning radio dataset. In the image below I colorised it using what we call spectral index, which tells us what causes this radio emission, like electrons accelerated by magnetic fields.

Sgr A* would be an tiny spec at the center of this image.

January 19, 2019 was my last opportunity of photographing and enjoying a lunar eclipse. It looks like the clock will continue counting until my next opportunity. Based on the weather forecast, tonight won’t be that night 🤷🏻‍♂️.
Best of luck to everyone that has clear skies tonight!

The 40cm Watcher robotic telescope at Boyden Observatory (South Africa) under a perfect clear night sky last night. Servicing and installing telescopes have many positive things. Enjoying these skies is on top of that list 😁
