"Existing models suggest that after a period of rapid expansion, the universe spent a few hundred million years cooling down enough for gas to coalesce and collapse into the first stars and galaxies began to form, a period known as the dark ages."

The Milky Way has about 60 satellite galaxies - including the notable Large Magellanic Cloud, which can be observed with the naked eye - although studies predict that our home galaxy should host an additional 100 or so very faint satellite galaxies we've not found yet.

There are about 200,000,000,000 galaxies in the known universe.

Beautiful, amazing and scarry all at the same time. What would it be like living within such.

"Queste osservazioni sono rivoluzionarie: si è aperto un nuovo capitolo dell’astronomia», commenta Paola Santini, ricercatrice Inaf a Roma e coautrice del nuovo articolo. «Già dopo i primissimi giorni dall’inizio della raccolta dati, Jwst ha mostrato di essere in grado di svelare sorgenti astrofisiche in epoche ancora inesplorate»

#GALAXIES || Scientists discover massive '#extragalactic structure' behind the #MilkyWay ||By B. Specktor / #LiveScience || https://www.livescience.com/zone-of-avoidance-giant-structure || Spotted by #AEROSPATIAL ||

#ResearchIntroduction 2/2:
What drives my interest in these surveys is the effect of the environment on #galaxies. I've been working this on since my #MSci #dissertation on "The cores of galaxies in the Coma cluster", and it is explicit in the full name of AGES – the #Arecibo #Galaxy Environment Survey. WAVES, the other survey I led, covers the Virgo cluster (the 'V' in WAVES). I've also investigated environmental effects at other wavelengths, such as ionised carbon in Virgo in a recent paper

#SPACE #SCIENCES || The mystery of X #galaxies || With their remarkable shape and rarity, cross-shaped galaxies are intriguing. Researchers believe they finally know how they are formed: by the #rotation of the supermassive #blackhole at their centre. | V.

#introduction
I'm an #astrophysicist at the #Kapteyn Astronomical Institute at the #UniversityOfGroningen in the Netherlands. I study the most massive #galaxies in the Universe and build #AstronomicalInstrumentation to observe them. I'm originally American but have lived in the #NL for more than 20 years now.

I love music, play guitar badly for nearly 40 years, and am an avid board and #TTRPG gamer. I have a deep fondness for comic books and strategy games. #astrodon #astronomy

My latest image shows an interesting grouping of #galaxies in the constellation Pegasus. The bigger one at right is NGC 7331, around 40 million light-years away. More interesting, though, is the smaller group at lower left, known as Stephan's Quintet. 4 of these 5 galaxies (distance 210–340 MLy) are actually very close to each other, and possibly will merge together; the fifth one just happens to be in the same relative location from our perspective but it's a lot closer (~39 Mly).
