- The #Perseverance press conference panel consists of 5 NASA managers and 1 Mars researcher – so the topic is likely some follow-up to "thediscovery of a potential #biosignature" in an outcrop reported earlier this year in https://ntrs.nasa.gov/api/citations/20250001217/downloads/Hurowitz%20et%20al%20LPSC.pdf while the specific rock to be discussed today was shown in April in https://science.nasa.gov/resource/meet-the-mars-samples-sapphire-canyon-sample-25/ and mentioned in August in https://www.eurekalert.org/news-releases/1094171 and the O-PTIR #spectroscopy method to hunt for microbial markers was discussed in March in https://www.u-tokyo.ac.jp/focus/en/press/z0508_00392.html

- 🎁Harald Günther turns 90 today—happy birthday! Generations of students used his textbook “#NMR #Spectroscopy—Basic Principles, Concepts and Applications in Chemistry” the most recent edition of which was published by Wiley-VCH in 2013. It first appeared in 1973 and later in several languages. An early PhD student of Günther was Klaus Müllen whose autobiography “The Chemistry Got to be Right” l-i-c.org/1139 will appear in August as volume 15 of the “Lives in Chemistry” series.
- A star with a weird color – Nova Lupi 2025 (V462 Lupi)1st photo is not annotated. Can you find the nova?2nd photo is annotated.3rd photo was deliberately mis-focused so that stars were larger disks instead of small points. This makes it easier to see the color.Note that there are plenty of orange stars and plenty of blue stars…but the nova has a unique color. To my eye it's a pale purple.Why does the nova have a weird color?4th image was taken from https://www.facebook.com/photo/?fbid=1771205990440705&set=pcb.10056320127790102 it's a spectrum of the nova. Most stars have a blackbody radiation distribution, but novae (that's the […]
