    Cosmic Seesaws: How Black Holes Balance Winds and Jets to Shape the Universe

    Introduction: Black holes as cosmic regulators Black holes are often imagined as voracious devourers, but new observations from a NASA X-ray instrument reveal a subtler role: these enigmatic objects act like cosmic seesaws. They tip toward powerful winds that push matter away or toward tightly focused jets that shoot matter and energy into intergalactic space.…

    NASA Watches Kepler’s Supernova Remnant Expand Over 25 Years with Chandra

    Kepler’s Supernova Remnant: A Historic Explosion in the Milky Way In 1604, astronomers observed a brilliant new star in the sky that would become known as Kepler’s supernova, the Milky Way’s most famous naked-eye stellar explosion. Today, NASA’s Chandra X-ray Observatory offers a long-awaited, long-running look at the remnant as it expands, giving scientists a…

    NASA Watches Kepler’s Supernova Remnant Expand Across Two Decades and Beyond

    Introduction: A 400-Year-Old Fireball Still Expands In 1604, astronomers watched what appeared to be a new star blaze across the night sky. Johannes Kepler documented the bright “nova” in a way that still informs modern astronomy. Today, NASA’s Chandra X-ray Observatory is used to study the Kepler supernova remnant (SNR) as it expands, cools, and…

    NASA Watches Kepler’s 1604 Supernova Unfold Over 25 Years Through Chandra’s Eyes

    Unveiling a 400-Year-Old Cosmic Event When Johannes Kepler first observed a bright point in the night sky in 1604, the eruption was celebrated as the last naked-eye supernova recorded in our Milky Way. Fast forward to today, and NASA’s Chandra X-ray Observatory is providing a fresh, high-energy view of that historic explosion. Over more than…

    Young Galaxy Cluster Surprises Scientists With Sun-Beat Heat

    Earth-Sized Mystery: A Galaxy Cluster That Outshines the Sun In a surprising twist to our understanding of cosmic evolution, astronomers have identified a galaxy cluster that is hotter than the surface of the Sun while still being remarkably young in cosmic terms. This finding challenges long-standing models that suggest younger clusters should be cooler as…

    Young Galaxy Cluster Astonishes Researchers with Extreme Heat

    An Unprecedented Find in a Young Universe A new astronomical discovery is turning heads in the science community: a very young galaxy cluster that is unexpectedly scorching. Researchers report that this cluster is hotter than the surface of the Sun, a temperature regime rarely associated with such youthful cosmic structures. The finding comes at a…

    Young Galaxy Cluster Surprises Scientists with Heat Comparable to Solar Surface

    Unexpected Heat in a Very Young Galaxy Cluster In a surprising turn for cosmology, researchers have identified a galaxy cluster that is both remarkably young and exceptionally hot—hotter, in fact, than the surface of the Sun. This challenges longstanding ideas that young clusters should be cooler as they form from the gradual assembly of surrounding…

    Could Ghost Particles in Galaxy Clusters Solve the Dark Matter Mystery?

    Unlocking the Dark Matter Puzzle For decades, scientists have sought to understand what makes up most of the universe’s mass. Dark matter cannot be seen directly with light, yet its gravity shapes galaxies and clusters. A growing line of inquiry asks whether dark matter particles could be long-lived but eventually decay, emitting detectable signals that…
