Intermission

Intermission - The drive to Geysir

Geysir, the biggest tourist spot in Iceland, is located about an hour and half drive east of Reykjavik on the highway, but because we were coming from further north in Vesturland, our path took us across roads that made for arguably the most epic drive I have taken (driving Western Australia's Pilbara Craton is a close second). This drive took us on Icelandic "F roads",…

Site 3 - Landbrotalaug, Snaefellsness Peninsula

Site 3 - Landbrotalaug, Snaefellsness Peninsula



Our third site was the rather unassuming site of Landbrotalaug. It is located on the Snaefellsness Peninsula, made famous by Jules Verne in his book "Journey to the Center of the Earth". There, the Snaefells volcano, situated near the tip of the peninsula, is actually the entrance!

What is interesting about Snaefells is that the rocks are a bit…

Site 2 - Deildarthunguhver in Vesturland

Site 2 - Deildarthunguhver in Vesturland

After the muddy waters of Seltun, I was looking forward to some clearer waters to sample. I got my wish granted at Deidarthunguhver. This hot spring is extraordinary. Water emerges out of the rock bubbling and fountaining furiously at 98C, at the highest flow rate in Europe. 198 liters / second (52 gallons per second)! …

Site 1 - Seltun

Site 1 - Seltun, Reykjanes Peninsula

After loading our trusty 4x4 Suzuki Jimny with our sampling gear, we headed off heading west from Reykjavik. Leaving the highway to go in the direction of Kruysuvik, the paved road soon ended (I love that about Iceland, the driving is always so much fun!). Thankfully the rain had stopped by the time we got to our destination, which was…

¿Are the Venusian sulphuric acid clouds the by product of long dead anoxogenic photosynthetic organisms?

Posted by Andrew Planet on May 4, 2020 at 2:51pm 2 Comments

I just read the piece at the link below entitled "Study: Life might survive, and thrive, in a hydrogen world."

I'd been thinking on similar lines recently, on different atmospheres with early life, but I was considering anoxogenic bacteria whose byproduct is sulfur instead of molecular oxygen. ¿Had life evolved on Venus could its sulfuric clouds be the signature byproduct of such life with no branches ever evolving to produce the equivalent of Earth's Great…

100 years tomorrow 26th April 2020 since we looked beyond the Milky Way Galaxy

Posted by Andrew Planet on April 25, 2020 at 11:10am 0 Comments

Exactly 100 years ago tomorrow, the subject on whether this Universe is larger than the Milky Way Galaxy was brought up publicly at an event sponsored by the National Academy of Sciences, known as The Great Debate. Until then the Milky Way was thought to be this Universe.  Conference at the NAS http://www.nasonline.org/about-nas/events/annual-meeting/nas157/
