This year’s public lecture series deals with the fiery relationship between Sun and Earth. In German. Looking forward to topics like aurora borealis, dangers of solar storms, space weather forecasting and more. www.mps.mpg.de/im-feuerwerk... #Sun #spaceweather #flare #CME #solarstorm ☀️🔭🛰️

100 hours.

Ακούς @thepressproject.libretooth.gr.ap.brid.gy και παίρνεις την εντύπωση ότι για όσα συμβαίνουν στο Ιράν φταίνε σχεδόν αποκλειστικά οι κυρώσεις και Ισραήλ/ΗΠΑ, δηλαδή ακριβώς η αφήγηση του καθεστώτος, το οποίο ουσιαστικά ξεπλένουν.

Congratulations! For re-examining and improving a 33-year-old reconstruction of #solarirradiance, #MPSGoettingen scientist Theodosios Chatzistergos received the #KeesdeJagerPrize for best publication in the journal #SolarPhysics. The award was now presented. www.mps.mpg.de/kees-de-jage...

I currently have three funded PhD positions available for applications. Links for more info and to apply are in my profile page: research-portal.uea.ac.uk/en/persons/t...

Πέφτουμε από τα σύννεφα... Αυτό όμως που μου έκανε εντύπωση, και ελπίζω να κατάλαβα λάθος, είναι ότι, παρά όλα αυτά, το Πανεπιστήμιο Πατρών συνεχίζει να τον υπολογίζει ως διδακτορικό φοιτητή! www.reportersunited.gr/17718/lobby-...

Does the solar magnetic field migrate towards the poles faster than expected? Results using the data from #ESA ’s #SolarOrbiter are published today in #ApJL. More infos here: www.mps.mpg.de/sun-first-gl... @science.esa.int @ioppublishing.bsky.social

The deadline for submission to the topical issue has been extended until 31 January 2026. ☀️🔭🧪

Our comment to the DOE and EPA about the DOE Climate Working Group report is now posted on ESSOAR preprint server. It has a DOI and can now be cited! essopenarchive.org/users/260056...

Grateful to @andrewdessler.com for coordinating this (and keeping us on schedule)! I feel proud for having contributed to this monumental effort alongside some of my role models in this field. It felt necessary to respond to the report that was misleading at best and dangerous at worst.

Proud to be part of an effort by 85 scientists from around the world to respond to a misleading DOE climate science report last month. The fact that our rebuttal is more than 3x the length of the DOE report is a good example of Brandolini's Law in action...

There's a lot of very interesting material in the response from experts across many domains if you want to learn something solar reconstructions, coral reefs, U.S. temperature data, atmospheric temperature trends, climate models, etc. Andrew did a great job organizing with a very small (30d) window.

Great article in the NYTimes about our comment to the DOE about their climate report. Gift link: www.nytimes.com/2025/09/02/c...

Our 400+ page comment on the DOE climate working group report is now out. Our conclusion: The merchants of doubt are back, and they're coming for climate science.

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report. This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it. Example: refuting one sentence.

We are pleased to announce that the Topical Issue (TI) on “Space Climate: Solar Extremes, Long-Term Variability, and Impacts on Earth’s System” is now open for submissions at the Journal of Space Weather and Space Climate (JSWSC) site: www.swsc-journal.org/topical-issu.... 🧪🔭☀️

Could the #Sun be responsible for #ClimateChange? In his #TEDx talk on the subject, #mpsgoettingen director Sami Solanki looks into our star’s capricious past, at its more recent behavior – and gives a clear and definite answer. View here: www.youtube.com/watch?v=bQ21...

#ParkerSolarProbe was in the right place at the right time in Sept 2022: It passed through a magnetic reconnection region in the Sun's corona. #SolarOrbiter observed the event from a distance. Study led by #SwRI in @natastron.nature.com . #NASA @science.esa.int www.mps.mpg.de/flying-throu...

And here's a video of the flare!

Here are some great shots from our #GREGORSolarTelescope observation campaign in July. Peering into the #photosphere and #chromosphere, we caught several emerging active regions – and a #flare! This will help us study the plasma dynamics in active regions and how energy builds up to create a flare.

A quick reminder that the claim that "TSI variability can explain more than 70% of the temperature variability since preindustrial times" is based on outdated and implausible TSI models. Thus, it is a misleading statement. link.springer.com/article/10.1... www.sciencedirect.com/science/arti...

The German radio station "Bayern 2" has devoted the latest episode of its show “IQ” to the #Sun - and to Solar Orbiter’s first views of the solar poles. Interview partner is Sami Solanki of #mpsgoettingen : www.ardaudiothek.de/episode/urn:... In German. Enjoy! #SolarOrbiter @science.esa.int

🧵 Did you know that sunspots, those dark "marks" on the Sun surface have been observed for over 400 years? They are the key to studying solar activity, but combining them into a single story is a challenge! A new study has tested methods for "calibrating" this historical data, collected by 🔭 🧪

New paper alert 🧪☀️☄️ In this study, we assessed different methods of combining sunspot number records from various observers, which will strengthen our ability to construct a consistent solar activity history. doi.org/10.1051/0004...

Willie Soon's latest video is a textbook case of climate-change propaganda. This short clip shows him making outrageously misleading claims about the Sun. 🧵🧪 #climatechange

Yet another paper by Willie Soon built entirely on the assumption that two outdated and scientifically unsupported total solar irradiance (TSI) reconstructions, Hoyt & Schatten (1993) and Bard et al. (2000), are still plausible.

We're advertising a 3-year postdoc post on long-term solar activity reconstructions, using data from tree rings, ice sheets, sunspots and spacecraft. Closing date: 4 June. jobs.reading.ac.uk/Job/JobDetai...

New paper alert 🧪☀️🔭⚛️☄️ In this study, led by Prof. Ilya Usoskin, we reconstructed solar activity, expressed in terms of sunspot numbers, throughout the first millennium BCE using annually resolved ¹⁴C concentrations in tree rings, resolving individual solar cycles. doi.org/10.1051/0004...
