Les galaxies primordiales contiennent beaucoup plus de petites étoiles que prévu
🔸 "Pour la première fois, des astrophysiciens ont mesuré avec précision la fonction de masse initiale dans un échantillon de galaxies massives et quiescentes situées au-delà de l'Univers proche."

Last week we had 'Black Hole Stars' that were the predesesors of the Super Massive Black Holes that are at the centre of our galaxies, now here's what happened a bit later in the process, when those fledging SMBH were finding each other and falling into another.
Imagine witnessing three of the things collide with each other! Such awesome and space bending power!

Ancient clash with 'Kraken' galaxy 12 billion years ago helped form Milky Way
By Ellen PhiddianA new study suggests one of the most significant clashes in the history of the Milky Way, dubbed the "Low-energy-Kraken-Heracles" merger, happened 12 billion years ago.

Astronomers Discover a Brand-New Type of Object: Part Black Hole, Part Star
Credit: Jose-Luis Olivares/MIT At the cosmic dawn, the universe was sprinkled with giant black holes—monstrosities so huge that scientists are still struggling to explain how they could have even existed. The answer may lie in a never-before-seen object from this cosmic era. In a paper published today in Nature, astronomers report the discovery of an extremely unusual, bright spot of red from the early universe. Externally, it looks like an enormous star about the size of the entire solar […] -

💁🏻♀️ TIL: 🌌🔭 Ethan Siegel traces 20 decades of cosmic #discovery, from #Einstein’s 1919 #eclipse test to #JWST’s “Little Red Dot” #galaxies in the #2020s.
Each decade gets one hallmark finding, including #darkmatter’s first hint, the #BigBang’s theoretical development, and the 1998 discovery of #darkenergy.

An article published in "The Astrophysical Journal" reports the results of a study of dust generated by red giant stars towards the end of their lives under conditions similar to those existing in the first galaxies of the universe. A team of researchers lused observations conducted with the James Webb Space Telescope to study the Sextans A dwarf galaxy, where the environment is very metal-poor.

Black Holes are Mysterious, Yet Also Deceptively Simple
NASA/JPL Physicists consider black holes one of the most mysterious objects that exist. Ironically, they’re also considered one of the simplest. For years, physicists like me have been looking to prove that black holes are more complex than they seem. And a newly approved European space mission called LISA will help us with this hunt. Research from the 1970s suggests that you can comprehensively describe a black hole using only three physical attributes – their mass, charge and […]https://onlinemarketingscoops.com/2026/07/18/black-holes-are-mysterious-yet-also-deceptively-simple/

🔭 #Roman is scheduled to launch on Sunday, Aug. 30. Roman will conduct three main wide-field surveys and search for #exoplanets. The telescope’s capabilities will allow scientists to map billions of #galaxies 🌌 https://www.nasaspaceflight.com/2026/07/roman-prelaunch-update/
Roman will detect #NEOs ☄️ as a natural result of its wide-field cosmology surveys. NEOs are #asteroids within 1.3 astronomical units from the Sun. Potentially hazardous asteroids are Atens or Apollos greater than 140 meters in diameter 📏 https://arxiv.org/html/2508.14412v1

Surprising claim of superstringy universe may be based on a mistake
Mix-up in distance scales may explain hints of anisotropy in distribution of galaxies.
