Johannes Kepler, not Newton or Einstein, is science’s best role model
People often look to Einstein or Newton as a scientist's best role model.
But Kepler did something more important: he changed his mind when the evidence demanded it.

Astronomers expected a celestial sign, like a #comet, during the planetary conjunction of #Jupiter and #Saturn in the “Fiery Trigon” of 1604. Astronomers watched intently. On Oct 9, 1604, Kepler’s Supernova exploded. It outshone Jupiter and #Sirius, rivaling #Venus as the sky’s 3rd-brightest object. Visible during the day for weeks and to the naked eye for 18 months, it was a miraculous “new star”. Today's science claims: it was all a coincidence.

“Here comes the sun”*…
Earth’s magnetic field provides an imperfect shield against solar stormsFurther, in a fashion, to last Wednesday’s post… We’ve looked before (e.g., here) at the potential havoc that solar storms could wreak on our electified lives. Now, as Paul Voosen reports, scientists are speculating on a defense, suggesting that gases released from satellites could slash the threat of severe “space weather”…
When violent eruptions from the Sun slam into Earth’s magnetic field, they do more than paint aurorae across the night sky. They can scramble the electronics of satellites and induce powerful ground currents that knock out electrical grids. It’s been estimated that a one-in-a-100-year solar storm like the 1859 Carrington Event could cause more than $3 trillion of damage to the power grid alone. [See here.]
Yet for decades, society’s only defenses have been better space weather forecasts and more durable technology on the ground and in space. Now, a small group of space physicists says humanity should intervene and weaken solar storms in real time. In a study published [recently] in Space Weather, the researchers describe a provocative proposal called “StormWall”: a fleet of satellites that would release hundreds of tons of gases into space just before a solar storm strikes Earth. Computer simulations suggest the artificial cloud could cut the intensity of a major solar storm by half or more. “It’s as if you could install an airbag in the magnetosphere,” says Daniel Welling, a co-author and space physicist at the University of Michigan.
Call it “helioengineering”—a deliberate intervention in the near-Earth space environment. But unlike controversial geoengineering proposals to mitigate global warming, which would inject long-lived Sun-blocking particles into the atmosphere, StormWall’s protective gases would dissipate within hours, says Brian Walsh, the study’s lead author and a space physicist at Boston University. “It’s waiting for us to do some temporary modification.”
The proposal would require more extensive simulations and testing. But it is “highly innovative and appears to be quite feasible in the near term,” says Allison Jaynes, a space physicist at the University of Iowa. It’s a “laudable idea,” adds Gurudas Ganguli, a space physicist at the U.S. Naval Research Laboratory (NRL)…
[Voosen explains the technology proposed and considers the challenges in its implementation…]
… Of course, like an airbag, StormWall would have to be replaced if deployed. But just as NASA and other space agencies are studying how to protect the planet from asteroids [and here], Walsh says there’s a good argument for fortifying an electronics-dependent society against massive solar eruptions. “If we lose all our power grids and can’t use the internet for 6 years, it would be traumatic.”
“Radical proposal would block solar storms with orbital ‘airbag’” from @science.org.

As we apply sunscreen, we might send bright birthday greetings to Godfried Wendelen; he was born on this date in 1580. And astronomer (and Catholic priest) known as “the Ptolemy of his time.” Despite the tenets of his church, Wendelen was an audacious proponent of the Copernican theory that the planets orbit around the sun. He made more accurate measurements of the distance to the sun than those previously made by Aristachus (2,000 years earlier) from the geometrical relationships at the exact time of a half-moon.
Wendelen is considered by many as a precursor of Kepler and Newton, and was in fact cited by Newton in his Principia. The crater Vendelinus on the Moon is named after him

@akkana @dmarti @pluralistic Doctorow gave an inspiring talk at #kepler Bookstore in Menlo Park last fall where he pointed out that the rule of law in the USA is also in a crisis situation. The rise of lawlessness cuts both ways, and could also be viewed as a means of resistance and subterfuge.

Космос из школьного кабинета: Как мы научили ИИ законам Кеплера после «разноса» от ученых
Существует стереотип, что современная наука об экзопланетах — это прерогатива NASA и ученых с миллионными грантами. Мы — команда обычных школьников и наш наставник — решили доказать, что для открытия новых миров достаточно ноутбука, Python и понимания того, что Машинное Обучение (ML) без физики — это просто генератор случайных чисел. Это история проекта ExoLogica AI : путь от сокрушительного провала на конференции до создания гибридного интеллекта, который видит то, что иногда пропускают профессиональные телескопы.

A Cool Earth-sized Planet Candidate Transiting a Tenth Magnitude K-dwarf From K2
-
Nově objevená exoplaneta, nacházející se relativně blízko (146 světelných let), má asi 51% šanci nacházet se v obyvatelné zóně své hvězdy. Hodně by záviselo na složení a hustotě atmosféry - pravděpodobnost, že klima planety připomíná spíš Mars, než Zemi, je poměrně velká.
Planeta HD 137010 b byla objevena analýzou starších dat observatoře Kepler.
Planety na vzdálenějších oběžných drahách, podobných Zemi, je daleko těžší v datových sadách identifikovat. Přechod této planety přes pozorovatelný kotouč svojí mateřské hvězdy trvá 10 dní (v případě Země by to bylo 13 dnů)

NASA KI, welche 370 Exoplaneten aufgespürt hat, untersucht nun #TESS Daten
Wissenschaftler haben über 6.000 Planeten entdeckt, die andere Sterne als unsere Sonne umkreisen & als Exoplaneten bezeichnet werden. Mehr als die Hälfte dieser Planeten wurde dank Daten aus der inzwischen eingestellten #Kepler-Mission & der aktuellen TESS-Mission (Transiting Exoplanet Survey Satellite) entdeckt.

Der Hinweise auf das Kepler-Gymnasium in Reutlingen beweist, dass Schulleitungen auch anders agieren können, wenn sie das entsprechende Rückgrat, oder eine entsprechende Grundhaltung haben.
Das Freiburger Kepler Gymnasium berühmt sich selbst, weltoffen zu sein, Rassismus nicht zu dulden, bietet nun jedoch der AfD eine Bühne. Dann muss die Schulleitung auch mit Kritik hieran leben.
Wenn die Schulleitung ganz legalistisch hätte sein wollen, wäre auch eine Absage der Podiumsdiskussion in Frage gekommen, denn es gibt für Parteien kein Recht auf Durchführung solcher Veranstaltungen auf dem Schulgelände.
In Freiburg bietet allerdings nun die Schulleitung, einer gesichert rechtsextremen Partei ein Forum, um sich den Schüler:innen zu präsentieren. Das ist nicht demokratisch, sondern zeigt den politisch-moralischen Verfall deutlich auf.

AfD am Dienstag, 27.Januar 2026 in Freiburg im Kepler-Gynasium
Schulleiterin Insa Wodtke bewirbt ihr Kepler Gymnasium u.a. mit folgenden Worten: "Wir sind eine weltoffene, von Internationalität geprägte Schule.".
So 'weltoffen", dass am 27. Januar die Schule ihr Tore weit öffnet für die AfD: Stadtrat und Landtagskandidat Karl Schwarz darf ab 11:30 Uhr Werbung für sich und seine AfD machen.
Schwarz scheiterte vor einem Jahr vor Gericht damit, einen Artikel im Amtsblatt unterzubringen, den u.a. @RDL wie folgt beurteilte: "allgemeinen rassistischen Duktus und eigenen verinnerlichten rassistischen Sterotypen-Sermon".
Diesem Herrn Schwarz bereitet die Schulleitung nun ein herzliches Willkommen, damit er im Rahmen einer Podiumsdiskussion für seine menschenfeindliche Partei und sich selbst Wahlwerbung machen kann.
Das Reutlinger Kepler-Gymnasium zeigte 2024 mehr Rückgrat und lud bei einer ähnlichen Veranstaltung die AfD aus!

#KnowledgeBit: #Kepler-452b is an #Exoplanet sometimes quoted to be an #Earth2.0 or Earth's Cousin based on its characteristics. It is the first potentially rocky super-Earth planet discovered orbiting within the habitable zone of a star very similar to the Sun.
Of the 1,030 confirmed planets from Kepler, a dozen are less than twice the size of Earth and reside in the habitable zone of their host stars.
