🔭 Astronomer Cecilia Payne-Gaposchkin made one of the most fundamental discoveries in the history of science: stars are made primarily of hydrogen & helium. Her 1925 PhD thesis is widely regarded as the most brilliant ever written in #astronomy. She was born #OTD in 1900. #WomenInSTEM #AstroSky

Europe has made remarkable progress cleaning up its electricity. In 2024, just 29% of European electricity came from fossil fuels - down from 53% in 2005. But electricity is only 23% of Europe's total energy use. Look at other sectors & it changes dramatically. More here: substack.com/@janrosenow

#OTD in 1990, the Hubble Telescope was launched into orbit. Nancy Grace Roman, the "Mother of Hubble" & #NASA's first Chief of Astronomy was the foundational architect who transitioned the concept of a large space telescope from "hopeful speculation" to a funded reality. #WomenInSTEM #astronomy

#WorldHealthDay reminder: a healthy planet is the foundation of our health. Forests clean the air we breathe. Oceans provide food and regulate the climate. Soils grow what we eat. Freshwater sustains life. Protecting ecosystems means protecting people.

This is the face of a lunar scientist who has just been told that the #Artemis II crew saw SEVERAL impact flashes (the flashes when meteors hit the lunar surface) in real time 😃 🌓💥

As part of the flyby, crew will lose comm with Earth for ~45 minutes. If they were to emerge from the pass and never regain comm with Earth, we have a protocol for that - called Permanent Communications Loss - that enables the crew to being able to return to Earth without any communications.

Orion-Raumschiff jetzt über 50.000 km von der Erde entfernt. Zum Vergleich: ISS 400 km, Wettersatelliten 36.000 km, Mond ca. 400.000 km.

Aber in dem Zusammenhang interessant: Es gibt auf dem Weg zum Mond einen Punkt, an dem die Anziehungskraft des Mondes stärker auf das Raumschiff wirkt als die der Erde. Da der Mond weniger Masse hat (81 Monde würden die Erde aufwiegen), ist der Punkt nicht auf halber Strecke, sondern näher am Mond.

Und es soll wohl zu einer Konstellation kommen, bei der die Sonne vom Mond wie bei einer Sonnenfinsternis bedeckt wird - so ähnlich gab es das schon bei Apollo 12. www.nasa.gov/image-articl...

Climate has almost disappeared from our conversation. But it remains the most pressing challenge of our times. Last week the WMO said the planet is “more out of balance than at any time in observed history.” Energy security and climate security are not competing priorities.

#OTD in 1936, Danish seismologist Inge Lehmann wrote a famous letter to a colleague outlining her theory that seismic waves (P-waves) recorded from distant earthquakes indicated Earth had a solid inner core. Her discovery fundamentally changed our understanding of the Earth's interior. #WomenInSTEM
