I am going to just run this script at weekends, so all the data is uploaded as soon as I can after collection. Once transferred to the gopher server, the data is deleted from the Raspberry Pi.

Some chemicals that we have produced remain in the environment pose a huge risk to ecosystems and human health, the problem is complex, but it does appear there are some solutions to this. So-called forever chemicals could stay indefinably, however science is finding a way to deal with these.

Potential Ozone Depletion From Satellite Demise During Atmospheric Reentry in the Era of Mega-Constellations

Interesting paper that was published in Geophysical research letters looking at potential damage to the Ozone layer from Satellites re-entering the Earths atmosphere and burning up. The specific issue seems to be related to the Aluminium Oxidizing, and then this travels down to the Ozone layer and causes a chemical reaction.

Give the number of Satellites in orbit and the importance of the Already fragile Ozone layer, this is not good news.

You can read the research here

There is a Fediverse discussion here that is quite interesting, I have also started a Science Forums discussion

Update : 2/4/2025: To give an idea what is up in orbit, this graphic is an interactive representation of all the satellites that are up there.
Update June 29 – Satellite collisions cause a chain reaction

Update June 25 – Near-future rocket launches could slow ozone recovery

Update July 3rd – More re-entry stats

Update 3rd July Thousands of satellites are due to burn up in the atmosphere every year – damaging the ozone layer and changing the climate

New tachyon study could unlock the secrets of time travel and reality

Interesting article published on Europe Says. I have asked on Mastodon where the link to this was posted, that if Tachyons have mass, if this should be factored in to the missing mass, which I think we are suggesting is filled with Dark Matter. So, another part of the hidden universe that has some mass. We are trying to account for where all the mass is located.

I don't fully understand the physics behind all this though.

This was posted to the Fediverse. The original post from COSPAR, The Committee on Space Research (COSPAR): can be found here

This is an upcoming workshop looking at the environmental impact of spacecraft reentry in to the Earths Atmosphere.

This workshop will address the impact of spacecraft re-entry on the atmosphere. The aim is to bring together atmospheric chemists and physicists, material experts, the space industry, and international space research related organizations to highlight the gaps in our understanding of the modelling and how we can improve testing to obtain relevant data and suggest appropriate mitigation and regulatory measures. 

This sounds like a fascinating area of research and discussion, as any exploration of space needs to take into account any environmental impacts.

It will be interesting to learn about the findings and conclusions from this, as it will open up further discussion on the topic(s) raised.

So, further to my previous post on this topic, Professor Stefan Rahmstorf has written an article for Livescience suggesting that the collapse is no longer a low probability. You can read the article here

I think this Daily Mail article demonstrates how poor journalism is getting in 2025. This is their article on the Planet K2-18b.

While the JWST has found some indications that life may exist on the planet, due to the Hydrogen Atmosphere and also the discovery of

• Di Methyl Sulfide
• Dimethyl Disulfide

The WikiPedia article tells a much different story.

Even the first part of this quote is helpful in that it says the press release was irresponsible. And that the data collected so far is not enough to confirm any life.

Astrophysicist and science writer Ethan Siegel denounced the press release as "wildly irresponsible" and astronomer Ryan MacDonald pointed out that the team's analysis was flawed because it only compared a select few chemicals to the data.[5] According to MacDonald, a proper statistical analysis of DMS and DMDS in K2-18b's spectrum would instead give a false positive probability of about 28%, corresponding to a 1σ confidence for the these two chemicals.[5] A 1σ significance does not qualify as a meaningful detection.[5]

The fact that the DM article also somehow has a section where someone has used AI to extrapolate what life may look like is rather ridiculous, as is the fact that according to that, the frog has 3 eyes and looks as it does to allow for the lower light level on the planet, this is odd given the fact the Wikipedia article suggests the light level on K2-18b may be the same or similar as it is on Earth, due to the distance from its star and the size of the star as well as other factors.

I think whoever thinks using AI to extrapolate what alien life may look like is risking their entire science career and credibility and this person was apparently from Cambridge University, so the reputation of Cambridge university is also going to be questioned.

I am baffled as to how much of this gets passed editorial in mainstream press.

In the meantime, if you really want to learn more, I strongly suggest you read actual science papers.

Granted, I think arXiv is pre-prints, but at least these papers are written by people who have a clue as to what they are talking about. It is also essential to be able to dig deeper and do your own research so when asking questions you can refer to decent sources of information.

I think it is also important to remember this planet is >120 light years away, so the information being picked up took >120 years to reach the JWST, therefore we are looking back in time. So it is important to understand that what is there right now in 2025 may be different to what may or may not have been there in 1905 when that light started its journey. Or at least this is how I understand things

If you want to read and have a good laugh, then read the Daily mail and other mainstream media.

Today we look at Evidence in Science. This is more general to science, but it is important to understand the science processes in research.
