Every time we point a powerful telescope at the night sky, we stage a quiet confrontation with time itself. Light doesn’t arrive instantly; it travels, carrying a record of where it came from. That simple limitation turns observatories into time machines, letting us witness galaxies as they were long before humans existed. The big story ...
The cosmos just threw us a curveball: a thunderclap of gravity from a collision so heavy, it shouldn’t exist under the usual rules of star death. In a hypothetical scenario involving detection during an observing run, the event forged a new black hole roughly about two hundred twenty-five times the Sun’s mass, pushing deep into ...
The universe is vast and mysterious, with over 85% of its mass composed of an invisible substance known as dark matter. Unlike ordinary matter, dark matter does not emit, absorb, or reflect light, making it challenging to study directly. Scientists continue to delve deeper into this enigma, uncovering its role in cosmic phenomena and the ...
The extraordinary features of a rapidly moving celestial object are scintillating astronomers’ interest. Upon initial discovery, A11pl3Z was given a name but recently NASA has confirmed it as 3I/ATLAS, the third interstellar object out of four comets or asteroids discovered. Unlike the comets or asteroids which are bound to the sun’s asteroid belt and viewable ...
Jupiter-sized exoplanets which emerge as a proxy for accelerating self-sabotage by instigating tremendous outbursts from their parent stars seem as violations to the conventional structure of planetary systems; astronomers have identified such a diabolic planet, HIP 67522 b. Located within its parent star’s magnetic field, HIP 67522 b’s orbital position subjects it to flare beams ...
Behind clouds of interstellar dust, a cosmic drama is playing out deep in the southern constellation of Chamaeleon. The Chamaeleon I dark cloud is one of the closest places to Earth where stars are born. It is only 550 light-years away. In this “stellar nursery,” newborn stars break through the darkness and light up huge ...
For most of human history, the night sky has been a place where stars, planets, and faraway galaxies can be seen. But what was there before the first stars came to life? Was the universe full of light when it was young, or was it a dark void? The answer is much more interesting than ...
The Sun’s poles have long been a cosmic mystery buried from Earth’s perspective by the simple fact that our planet, along with every other spacecraft, orbits within the equatorial plane. Thanks to the European Space Agency’s (ESA) Solar Orbiter spacecraft, however, mankind has now seen the solar south pole in history. Captured in March 2025, ...
At the core of the galaxy Messier 87 (M87), a cosmic behemoth is challenging preconceptions. Renowned for being the first black hole ever directly photographed, the supermassive black hole M87 has just exposed another amazing secret: it devours matter even faster and spins at a blistering 80% of the maximum speed in the universe. Using ...
Astronomers have been narrating a dramatic tale about the fate of our galaxy for more than a century: the Milky Way is relentlessly on collision with Andromeda, its enormous neighbor. Once judged unavoidable within 4–5 billion years, the cosmic smash-up would destroy spiral galaxies and create a new, shapeless elliptical galaxy known as “Milkomeda.” But ...
