Monster Black Hole Collision Challenges What We Know About the Universe

Suhail Ahmed

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 ...

Dark Matter and the Hidden Universe: New Frontiers in Astrophysics

April Joy Jovita

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 ...

Mysterious Object From Deep Space Heads Toward Earth’s Neighborhood

Suhail Ahmed

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 ...

‘Death Wish Planet’ Found Whipping Its Star Into Violent Eruptions

Suhail Ahmed

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 ...

The ominous Chamaeleon I dark cloud, the nearest star-forming region to Earth, is captured in this image taken with the 570-megapixel Department of Energy-fabricated Dark Energy Camera mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab. Chamaeleon I is one portion of the larger Chamaeleon Complex and is home to three reflection nebulae that are brightly illuminated by nearby newly formed stars.

Chamaeleon I: Where New Stars Light Up Cosmic Darkness

Jan Otte

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 ...

light didn't emerge unfettered after the Big Bang. Here, we see the phases following the Big Bang (top left), about 13.8 billion years ago, to present day (lower right).

Was the Early Universe Dark or Full of Light?

Jan Otte

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 ...

Sun’s Hidden Face: Humanity Views the Bottom of the Sun for the First Time

Suhail Ahmed

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, ...

How the Speed of Light Changed Everything We Know About the Universe

Jan Otte

The speed of light was a mystery for millennia, a fugitive constant that escaped measurement and understanding. Now among the most basic foundations of contemporary physics, it shapes our knowledge of space, time, and the very fabric of reality. Light’s speed is more than just a number; it’s a cosmic speed limit, a ruler for ...
