First Light for 4MOST - what an experience! Paranal Observatory is already a magic place on its own right - but getting a new facility on sky ... that's hard to top! www.aip.de/en/news/4mos...

4MOST Captures First Light

On October 18, 2025, the 4-metre Multi-Object Spectroscopic Telescope (4MOST) facility, installed on the VISTA telescope at the European Southern Observatory’s (ESO) Paranal Observatory in Chile, obta

The nice thing about LATAM airlines is that they are not afraid of having seat row #13.

Abell 262 is a galaxy cluster with some 100 members in the constellation of Andromeda, near the border to Triangulum. It is part of the Pisces-Perseus-supercluster. At the center is the cD galaxy NGC708. bit.ly/4lB3t… 🔭#astrophotography🔭📷

van den Bergh 140 is a blue reflection nebula in the constellation Cepheus. Adjacent is a large molecular cloud complex which makes the area around vdB140 a quite colorful region with blue, red and yellow tones. bit.ly/4lB3t68 🔭#astrophotography🔭📷

M110, aka NGC205, has a "wallflower existence" in Messier's famous catalogue. Although originally observed by Charles Messier in 1773, it never made it to his catalogue until it was added as its last entry not earlier than 1966! bit.ly/4lB3t…🔭#astrophotography🔭📷

vdB 133 is a reflection nebula powered by the yellow supergiant 44 Cygni. Its warm color makes the nebula appear white rather than the blue of reflection nebula powered by hotter stars. Adjacent is the large HII region LBN219. bit.ly/4lB3t68 🔭#astrophotography🔭📷

The NGC 70 group, aka VV166 or Arp 113 is a quite appealing object. It shows galaxies of various morphologies and the mutual proximity triggers bar instabilities, deformations and lots of tidal debris. bit.ly/4lB3t68 🔭#astrophotography🔭📷

As far as Germany is concerned, the DFG (the NSF equivalent) has several grant reviews per year, significant # of PhD positions are not subject to an annual cycle. So it is worth browsing the German Astronomical Society www.astronomische-gesellschaft.de) several times a year.

There is a tongue-in-cheek unit of volume called the Hubble-barn, equal to the volume of a cylinder with cross-sectional area of one barn (100 fm^2 - about the size of a uranium nucleus) and height of one Hubble length (14.4 billion light years).

It works out to three and a half gallons.

Ok folks: what is your favorite fact that you share with people (maybe a bit too) eagerly?
