Just some science facts. I’m a citizen scientist, member of the AAVSO and the Planetary Society, and a tiny weather station. If you can’t tell I just like science.

#PPOD: This unbarred spiral galaxy in the constellation Crater features a bright central core, where a supermassive black hole lies, surrounded by a disk of hot, young stars and spiral arms laced with streams of dust and more young stars. 🧪 🔭
An unbarred spiral galaxy seen almost edge-on, the sweeping arms closest to the foreground appear to be reaching down to the bottom of the image. Several bright foreground stars can be seen. The background is full of stars and distant galaxies.

Four Arianespace technicians monitor the Copernicus Sentinel-1D satellite being encapsulated inside the Ariane 6 rocket fairing. Members of ESA’s astronaut reserve Carmen Possnig, Meganne Christian, Anthea Comellini and Arnaud Prost in full training gear during a fire emergency drill. This image captured by the Copernicus Sentinel-3 mission on 26 October 2025 shows the ‘brightness temperature’ at the top of Hurricane Melissa as it moved through the Caribbean Sea towards Jamaica, where it was expected to make landfall. Part of the Red Spider planetary nebula: the nebula’s central star is hidden by a blotchy pinkish cloud of dust. A strong red light radiates from this area, illuminating the nearby dust.

#PPOD: An astronaut aboard the International Space Station photographed a sunset that looks like a vast sheet of flame. With Earth’s surface already in darkness, the setting sun, the cloud masses, and the sideways viewing angle make a powerful image. 🧪 🔭

Thin layers of lighter and darker blues reveal the many layers of Earth's atmosphere, seen at an angle from upper left to lower right from the International Space Station. The lowest layer is orange-brown line with clouds and dust and smoke. Nearest to the camera, Earth is dark from nighttime.

Orion on a roll 🌀
Last week, the Artemis II Orion - complete with crew module 👩‍🚀, @esa.int's European Service Module ⚡, solar arrays ☀️ + launch abort system 🛡️ - was rolled 10km to the Vehicle Assembly Building at NASA's Kennedy Space Center.
Next step - stacking on the SLS rocket 🚀

Close-up of NASA’s Orion spacecraft for Artemis II, showing NASA and ESA logos. Several hoses and cables are connected to the spacecraft, and part of the transport vehicle is visible. Wide view of the Orion spacecraft for Artemis II being transported near a large industrial building with bright interior lighting. The grassy foreground contrasts with the industrial setting, and various vehicles and equipment are visible under a partly cloudy sky.

#ICYMI: Could causality and locality be human constructs that blind us to the possibilities of alien physics? @danielwhiteson.bsky.social thinks perhaps so. (Side note: Beth's brain shorted out a few times during this #SETILive!) Watch the full conversation: buff.ly/hGPsu5g 🧪 🔭 👩‍🔬

Black holes galore! That’s what astronomers discovered when #NASAWebb peered into the distant cosmos. These smaller, fainter black holes are more similar to the one in our own galaxy. With Webb, scientists can study the black hole-galaxy relationship over time.

Science Fact:

The Universe's average colour is called 'Cosmic latte'. In a 2002 study, astronomers found that the light coming from galaxies averaged into a beige colour that’s close to white.

#PPOD: During its close flyby of Jupiter’s moon Io on December 30, 2023, NASA’s Juno spacecraft captured some of the most detailed imagery ever of Io’s volcanic surface. In this image, taken by the JunoCam instrument from about 1,500 kilometers above the moon... 🧪 🔭 👩‍🔬

📢 First bedrest samples arrive at @esa.int's new Exploration Biobank in Portugal.

🧪 +1400 tubes with blood, saliva, urine, stool and hair are now stored at –80°C in Europe's first biobank dedicated to human spaceflight research.

#PPOD: Comet C/2025 A6 (Lemmon) is brightening fast! Discovered in January by the Mount Lemmon Survey, it swings closest to Earth on October 21 and reaches perihelion on November 8—about 79 million kilometers from the Sun. Credit: Josh Dury Photomedia 🧪 🔭
Photograph of comet in the night sky, with a bright coma and long, blue tile that fades out to the upper right. The sky near the horizon is a soft pink due to a diffuse aurora caused by an ongoing solar storm. A few isolated trees can be seen in stark relief in the distance against the pink clouds on a hilltop.

Connected! The upper stage and main stage for the next #Ariane6 launch were joined together in their assembly building at Europe's Spaceport in French Guiana.

The two stages form the central core that will take the Copernicus Sentinel-1D Earth observer to orbit.

‪🆕 Researchers combed through images from ESA's #MarsExpress and #ExoMars spacecraft to find 1039 swirling dust devils 🌪️

Using these dust devils to track raging winds on Mars, their findings include that the strongest winds blow much faster than we thought!🧪🔭
www.esa.int/Science_Expl...
science.esa.int ESA Space Science @science.esa.int · Oct 8
This new catalogue of dust devils gives us a much clearer picture of the Red Planet’s weather and climate.

But besides pure science, it will also be useful for planning future missions, like dealing with the irksome dust that settles on the solar panels of our robotic rovers.

If you drilled a tunnel through Earth and jumped in, you would reach the other side in 42 minutes and 12 seconds, and your top speed would be 17,670 mph.

An unusual rock rests on the surface of Mars. It's a domed rock with a crack going straight up from the ground. A much smaller rock is off to the left.
