[Zoom on the #CosmicWeb] Have you dived into the deep fields of #Euclid revealed this Wednesday by the @ec_euclid ? Have you navigated between the thousands of #galaxies of different shapes, sizes, colors and masses? So many objects, near and far, fill our #Universe! sky.esa.int/esasky/?hide_welco

What if their spatial distribution could tell us something about two mysterious components : #DarkMatter and #DarkEnergy? This is the gamble taken by the scientists involved in the Euclid mission. To do so, they've designed some unrivalled #instruments: a camera with great depth of field and high resolution records the variety of shapes and spatial distribution of galaxies, while a #spectrometer coupled with a #photometer can determine the distances and masses of galaxies ...

[Focus on the #EnVision mission] Why have #Venus and Earth evolved so differently? This is the question to be answered by the EnVision #SpaceMission of the European Space Agency - ESA, scheduled for launch in 2031.

To this end, the European #probe will carry several instruments - including an imaging #spectrometer, to which IRAP staff are contributing. Observations will be made in the UV and IR domains, in order to monitor temporal variations in #surface temperature and gas concentrations within the #atmosphere - and thus gain a better understanding of interactions between the Venusian atmosphere and surface.

I started to work on a mini pocket spectrograph, the 3D model will be available for download, I just need to tune a few things.

I am also working on a little web based stuff to make sense of the things seen, strictly locally in the browser, on the client side.

It's a fun random side project, though I already bought about 8 different light bulbs just to see their spectrum...

[#ExoMars : report and update] The postponement of the ExoMars mission has given IRAP scientists the opportunity to update some of the components of the #Raman laser #spectrometer.

The spectrometer will analyse #samples taken from beneath the surface of #Mars that have been ground and powdered beforehand. It will be able to identify the #organic compounds present and will contribute to the search for #microbial life.

Launch scheduled for October 2028! Stay tuned 😜

This guy is telling me to not get carried away with the #kombucha project. I'm just going to buy some #fliptop bottles.

I am not buying a #conykeg

I am not going to learn all the ratios by heart

I'm not getting a freaking #spectrometer to measure the #electromagnetic absorption from time to time. Nah, #beer is for #nerds.

Me, I'm letting mold grow in a bottle, that's pretty much as far as this is going to go. I'm not gonna name my mold anything like Bertha or Lucy.

I wrote a blog post about my university major project from a few years back: Designing and making a visible light spectrometer for hobbyist scientists! gbryant.co.uk/posts/2023-03-19

It's summarising a year of work that was 5 years ago, so it's a bit of a mess. But I've been avoiding finishing the post so now I just want it to be done.

The actual spectrometer turned out really cool - for a start it actually works and could get you useful measurements! I've always wanted to go back and design an even simpler, cheaper version that would still be just as useful for doing science but more accessible.
