The Pacman Nebula
===============

NGC 281, the Pacman Nebula - a return to a familiar target in Cassiopeia. This time with a new setup and considerably more integration time, captured in the Hubble palette (HSO). The result is a view dominated by the warm red glow of ionized hydrogen and sulfur, punctuated by the brighter, subtly blue-grey core where the young star cluster IC 1590 drives the entire nebula's energy.

What fascinates me most about this object are the dark Bok globules - dense dust structures silhouetted against the glowing gas, slowly being eroded by the intense radiation from IC 1590. They look like they are being consumed, and in a sense they are. But deep inside their cold, shielded cores, gravity may be quietly winning - collapsing gas into new stars, born from the same clouds being stripped away around them.

NGC 281 - the Pacman Nebula in Cassiopeia. A return to a familiar object, this time with a new setup and considerably more integration time. In the Hubble palette (HSO), the dark Bok globules stand out with particular clarity - dense dust structures being eroded by the radiation pressure of the young cluster IC 1590, while possibly hiding new star formation deep within.

Sh2-171 โ€“ The Question Mark Nebula in Cepheus. A two-panel mosaic covering over 100 light-years of active star formation, powered by Berkeley 59 โ€” a cluster just 2 million years old. Its O5V star BD+66 1673 burns at 45,000 Kelvin, sculpting the dark pillars visible throughout the frame. Processed in Hubble Palette (HSO).

The Question Mark Nebula
====================

2,600 light-years away in Cepheus, a cosmic question mark is being written in gas and dust. Sharpless 171 (NGC 7822) is an active stellar nursery spanning over 100 light-years, powered by Berkeley 59 โ€” a star cluster just two million years old. Its brightest member, BD+66 1673, burns at nearly 45,000 Kelvin, sculpting the surrounding cloud into the elephant trunks and dark pillars you see here. A two-million-year-old star carving a hundred-light-year nebula. The universe doesn't do things small.

The foreground scatter of stars in the upper part of the frame belongs to NGC 7762 โ€” an unrelated open cluster that is 2.5 billion years old and just happens to share the same patch of sky. Ancient stars looking on as new ones are born.

@thomasfuchs if it was my decision, it would be mandatory to provide all services via plain HTML and enshure them to function at #Iridium bandwiths ( 2.400bit/s )!

@WeirdWriter I personally prefer #CLI / #TUI tools because they are faster, cleaner, work on #narrowband connectivity and barely sip system resources.

  • Just an overall better experience.

That's why I'm workibg on a CLI/TUI-centric, mininalist #Linux distro: @OS1337

  • Because there's no reason modern computing can't be done in an 80ร—25 MDA terminal!

NGC 2175 - the Monkey Head Nebula - in Orion, about 6.400 light-years away. A star-forming H II region (Sh2-252/NGC 2174) sculpted by the O-type star HD 42088 and dark dust lanes.

The Monkey Head Nebula
======================

NGC 2175 is a glowing star-forming region in Orion, about 6.400 light-years away. It belongs to the wider Sh2-252 complex (often discussed alongside NGC 2174) and spans a surprisingly large patch of sky.

Powered by the hot O-type star HD 42088, ultraviolet light makes hydrogen shine while dark dust lanes carve the familiar โ€œmonkeyโ€ silhouette. A stellar nursery in motion, shaped by radiation and winds as new stars emerge.

@emilianosandri @CatAClock @Daojoan the nice part about #Mumble is that it works excellent as #VoiceChat, with both #narrowband (down to #Codec2 @ 1200bt/s) and HQ (#Opus) and OFC low-latency (#Speex) being supported.

Anyone at @ubuntu still maintaining #PPP / #Modem support?

Because I did want to verify #Iridium data connections work but not only does it configure it as #MobileData and gnome-ppp isn't available on #UbuntuLTS 22.04.x's repos.
