Gran Telescopio Canarias Confirms And XXXVI as Andromeda’s Faintest Satellite
Astronomers have confirmed a new dwarf galaxy orbiting Andromeda (M31), built from as few as 46 detectable stars and estimated to be 12.5 billion years old. Designated Andromeda XXXVI, the object sits at a projected distance of roughly 119 kiloparsecs (about 388,000 light-years) from Andromeda’s center, making it one of the faintest satellite galaxies ever…

A Lost Planet May Have Saved Jupiter and Uranus’s Moons
For decades, astronomers have suspected that our Solar System may not have always looked the way it does today. The giant planets—Jupiter, Saturn, Uranus, and Neptune—likely formed much closer together before gradually migrating to their current positions. Now, new research suggests that an additional giant planet may once have been part of the Solar System.…

James Webb vs. Hubble: The “Pillars of Creation” Side-by-Side
Located 6,500 light-years from Earth within the Eagle Nebula (M16), these towering tendrils of interstellar gas and dust are arguably the most famous structures in the cosmos. When comparing the James Webb vs Hubble Pillars of Creation images, the staggering leap in optical technology becomes undeniable. For nearly three decades, our visual understanding of this…

Is the Universe Lopsided? How the Cosmic Dipole Anomaly Challenges Modern Cosmology
New theoretical and observational research suggests the universe may not be perfectly symmetric after all. A growing body of evidence points to a phenomenon known as the cosmic dipole anomaly, which implies that the large-scale universe may be slightly lopsided rather than uniform in all directions. This challenges a core assumption underlying modern cosmology and…

James Webb Cosmic Noon Black Hole: Found in a Well-Studied Region of Early Universe
The James Webb Space Telescope has identified a rapidly growing supermassive black hole dating back to an era known as cosmic noon, roughly four billion years after the Big Bang. Nicknamed BiRD (Big Red Dot), the object belongs to a newly recognized class of compact infrared sources revealed only by Webb’s sensitivity. The finding helps…

Satellite Megaconstellations Are Becoming a Serious Threat to Space Telescopes, Study Finds
A Growing Problem for Astronomy: Bright Satellite Trails in Space-Based Images A new peer-reviewed study published in Nature warns that rapidly expanding satellite megaconstellations pose a major and escalating threat—not just to ground-based observatories, but to space telescopes in Low Earth Orbit (LEO). Reflections from satellites already show up as bright streaks across astronomical exposures,…

Hubble Spots a Storm of New Stars: Inside a Turbulent Starburst Galaxy
A Dramatic Hubble View of NGC 1792 A tilted spiral galaxy fills the scene with chaotic beauty—patchy arms, bright blue star clusters, glowing red nebulae, and thick dust lanes winding through the disc. Light from NGC 1792 extends into the dark background, where foreground and distant stars scatter across the frame. This NASA/ESA Hubble Space…
