Using NASA's SPHEREx all-sky infrared survey, a team led by Matthew Stepney has identified 77 new heavily reddened quasars, more than doubling the known population. The objects appear caught mid-explosion, with depleted dust reservoirs and extreme intrinsic luminosity pointing to the long-predicted blow-out phase of black hole growth.

🌌 A galaxy from the young universe is forcing astronomers to rethink how fast massive galaxies can evolve. 🔭 Webb has revealed that XMM-VID1-2075 was already a slow rotator less than two billion years after the Big Bang.

Webb finds a massive early galaxy that should not have stopped spinning so soon

🌌✨ A new study using Webb and Hubble shows that the most massive young star clusters escape their birth clouds faster than smaller clusters. 🔭💫 The result offers a sharper view of how stellar feedback regulates star formation, shapes galaxies and may even influence the early environments where planets begin to form.

How Astronomers Read Twelve Billion Years of Cosmic History Through Oxygen

Imagine looking up at the night sky and realizing that the distant patches of light are not just static objects. They are giant cosmic archives holding secrets of their own violent pasts. Scientists have long pointed telescopes at distant galaxies to capture beautiful images of glowing dust and gas. But seeing a galaxy and understanding how it came to be are two very different challenges. The…

For the first time, astronomers have directly detected two supermassive black holes orbiting each other at the core of galaxy Markarian 501 — and they could merge in just 100 years. 🌌🕳️🕳️ A historic discovery that reshapes our understanding of galaxy evolution and opens a new window onto gravitational waves. 🔭🌊

🌑 Can a supermassive black hole shut down in just two decades? 🔭 A new study has documented exactly that: a galaxy 10 billion light-years away that lost 95% of its brightness in 20 years, challenging everything we thought we knew about how these cosmic giants evolve. 💫 Read the full article at SKYCR.ORG.

JWST May Have Found the Universe’s First Pristine Galaxy - New Study/Science Updates

Scientists found AMORE6, a galaxy almost free of heavy elements. Its existence strongly supports key predictions of the Big Bang model. Our knowledge of the Universe begins with the Big Bang, the moment when cosmic expansion first began. During this event, a process called Big Bang nucleosynthesis produced only the lightest elements: hydrogen, helium, and […] Summary The discovery of AMORE6, a…
