Habe eben nach der Nachrichtenmeldung nachgemessen:
Meine Wohnung ist in den letzten Jahrzehnten kaum größer geworden. Einzig zwei Zimmer mit Wasserschaden, die komplett saniert wurden, haben geingfügig an Fläche zugelegt.
Anwältin meint: kein Grund zur Mietminderung.

Sad to see the Goddard visitor center close. 🔭
mkirschenbaum.bsky.social Matthew Kirschenbaum @mkirschenbaum.bsky.social · Sep 14
Just a now routine little local bit of immiseration.
Sceeenshot of local news item: “NASA announced it intends to close the Goddard Visitor Center on Oct. 1. Located at 9432 Greenbelt Rd., the small visitor's center has long been a favorite spot for Route 1 families, with interactive exhibits about space and life-like NASA space models at an outdoor picnic area. It's long been an asset for home-schooled kids, with special science sessions throughout the year. It even has sensory-friendly hours, with lower lights and smaller crowds to help people who might find it stressful.”

🔭 Star Trails over One-Mile Radio Telescope

Image Credit & Copyright: Joao Yordanov Serralheiro

apod.nasa.gov/apod/ap25091...
The steerable 60 foot diameter dish antenna of the One-Mile Telescope at Mullard Radio Astronomy Observatory, Cambridge, UK, is pointing skyward in this evocative night-skyscape. To capture the dramatic scene, consecutive 30 second exposures were recorded over a period of 90 minutes. Combined, the exposures reveal a background of gracefully arcing star trails that reflect planet Earth's daily rotation on its axis. The North Celestial Pole, the extension of Earth's axis of rotation into space, points near Polaris, the North Star. That's the bright star that creates the short trail near the center of the concentric arcs. But the historic One-Mile Telescope array also relied on planet Earth's rotation to operate. Exploring the universe at radio wavelengths, it was the first radio telescope to use Earth-rotation aperture synthesis. That technique uses the rotation of the Earth to change the relative orientation of the telescope array and celestial radio sources to create radio maps of the sky at a resolution better than that of the human eye.

My animation of Mercury's escaping sodium exosphere over the course of a Mercury year. The only thing that changes is the magnitude of radiation pressure which is a function of where Mercury is in its orbit. Without radiation pressure, nothing would escape.

What is that unusual red halo surrounding this aurora? It is a Stable Auroral Red (SAR) arc. SAR arcs are rare and have only been acknowledged and studied since 1954. The featured wide-angle photograph, capturing nearly an entire SAR arc surrounding more common green and red aurora, was taken earlier this month from Poolburn, New Zealand, during an especially energetic geomagnetic storm. Why SAR arcs form remains a topic of research, but is likely related to Earth's protective magnetic field, a field created by molten iron flowing deep inside the Earth. This magnetic field usually redirects incoming charged particles from the Sun's wind toward the Earth's poles. However, it also traps a ring of ions closer to the equator, where they can gain energy from the magnetosphere during high solar activity. The energetic electrons in this ion ring can collide with and excite oxygen higher in Earth's ionosphere than typical auroras, causing the oxygen to glow red. Ongoing research has uncovered evidence that a red SAR arc can even transform into a purple and green STEVE.

2023 war wettermäßig deutlich durchwachsener als 2022. 2023 sind wir mit 178 Mond-Aufnahmen auf deutlich weniger Sichtungen gekommen als 2022 (219). Hübsch anzuschauen sind sie natürlich trotzdem

Happy Halloween 🎃

Here are the pumpkins I carved this year: An active red dwarf star and its gas giant planet. I call it an exo-pumkin. 🧪🔭
Two carved pumpkins, lit from within, photographed at night. The larger pumpkin is carved with a detailed, stylized image of the sun including prominances that arc off the limb of the sun. The smaller pumpkin is carved like a planet, resembling a stylized Jupiter.
