First stars
We are making discoveries so fast, it is hard to keep up. We are learning more and more about the origin of the universe each time. These first stars are probably long gone, but the light the produced is still moving.

Jupiter Moons
While the hunt for exoplanets is developing at pace, closer to home we keep finding new moons, esp around Jupiter. This week we found 12 new moons.
This is reported by Meson Stars – online news about space exploration, posted to Fedi by Frederic

Home Chemistry 10 – Alcohols Part 2
So further to the previous post. We tried this at the STEM group on 11/2/2023.
So using :
We had to weigh the sugar, a measuring cylinder was used to measure out the water. Yeast comes in 7g packets, so 3 are needed, in fact this dictated how much of the other ingredients were used. These ingredients are in a 1:1:1 ratio in a 250ml conical flash. We could see / hear the bubbles which showed the reaction was taking place.
After about 2 hours the result looked like this
The reaction can be written down as (source here )
Glucose/sugar + Water (in presence of enzyme yeast) = Ethanol + Carbon Dioxide
$\ce{C6H12O6 + Yeast + H2O –> 2C2H5OH + 2CO2}$
For the record the LaTeX source for this is
$\ce{C6H12O6 + Yeast + H2O -> 2C2H5OH + 2CO2}$
I have left this securely at the library and will check on it during the week. We can take a look at Code Club on Saturday,
Please note: This activity is NOT designed to teach anyone how to make Alcohol, it is designed to demonstrate the chemical processes involved in fermentation.
Ethanol, can of course be used in other experiments.

New Science discoveries 1
Something else found on the Fediverse. This was posted by Science Alert. The links should work from here too, if not you will need an account on a Mastodon instance. So lots of interesting things happening

Exoplanets
Another interesting article posted to Fediverse. This is about new exoplanet discoveries. I think this suggests we have found a Jupiter like planet around another star. However this is even further away than the previous planet discovered by Kepler. Another discovery by the Kepler Telescope, which I would guess one day will be observed by the HST, JWST or both.
A really good time to study STEM and get involved in resarch and new discoveries.

Home Chemistry 10 – Alcohol(s)
So further to the previous experiment. I am going to have a go at fermentation. I have the equipment required including an airlock
The experiment detailed in my previous post should produce ethanoic acid, where as this experiment will produce the alcohol (ethanol) $\ce{C2H5OH}$ As I am using an airlock.
Again, will try this at the next stem group meeting on 11th Feb, with the view to also doing something similar at the STEM Group meeting on 11th March as this coincides with Science week. We have other things planned for that too.
The use of universal indicator paper should help determine what is produced.
Please note: This activity is NOT designed to teach anyone how to make Alcohol, it is designed to demonstrate the chemical processes involved in fermentation.

Oil company profits
The Maths
BP = $27.7bn + Shell = $39.9bn = $67.60bn
These seem to be world wide profits, nevertheless, at the same time, people are choosing between eating a good meal and heating their homes.
Enough said
