James Webb Telescope Spots Rare ‘Cosmic Owl’ Formed by Colliding Galaxies
NASA’s James Webb Space Telescope has unveiled the “Cosmic Owl,” a jaw-dropping image of two colliding ring galaxies forming a structure that resembles an owl’s face. This double-ring formation is extraordinarily rare, and the event is shedding light on galaxy evolution, black hole dynamics, and rapid star formation. Led by Ph.D. student Mi...

NASA’s Chandra Spots Unexpectedly Strong Jet from Distant Black Hole at Cosmic Noon
NASA’s Chandra telescope has spotted two powerful black hole jets from over 11.6 billion light-years away. Detected during the universe’s cosmic noon, these jets reveal rare high-speed behaviour boosted by Big Bang remnants. The findings, which factor in relativistic effects, shed new light on early black hole growth and will be published in Th...

Black Hole Mergers Explained: What Happens When Two Black Holes Collide in Space?
Black hole mergers are among the most energetic events in space. Two black holes gradually lose energy through gravitational interactions, drawing them closer until their event horizons stretch and merge. Gravitational waves released during the process are some of the most powerful forces in the universe, with part of the black holes' mass converti...

Cosmic Explosions Even More Powerful Than First Thought: Study
The biggest explosions since the Big Bang set the universe in motion some 13 billion years ago produced even more energy than first thought, scientists said Wednesday.

Edge Of Spiral Galaxies Could Be Rife With Colliding Black Holes: Study
The outskirts of spiral galaxies like our own Milky Way could be crowded with colliding black holes of massive proportions and a prime location for hunting the sources of gravitational waves, a study led by an Indian origin researcher has found.

Gravitational Wave Detectors Could Unlock Dark Matter Mystery
The same instruments used in the Nobel Prize-winning discovery of gravitational waves caused by colliding black holes could help unlock the secrets of dark matter, scientists, including one of Indian origin, say.

Scientists Detect Gravitational Waves From Black Holes Colliding 3 Billion Light-Years From Earth
The first gravitational wave discovery was announced in February 2016 and the second a few months later.

Gravitational Waves Form 10 Million Years After Black Holes Merge
Gravitational waves are formed around 10 million years after two galaxies collide and their central black holes merge - about 100 times faster than previously thought, a new study has found.

The Big Gravitational Waves Breakthrough: 10 Points We Can All Understand
Over a billion years ago, two black holes collided and merged in space. The wobble they generated - gravitational waves - hurtled through space and was heard as a "chirp" on Earth in September.

But What Are Gravitational Waves?
In a landmark discovery for physics and astronomy, international scientists said Thursday they have glimpsed the first direct evidence of gravitational waves, or ripples in space-time, which Albert Einstein predicted a century ago. Here are 11 facts to help you understand this development:

'Funky Light Signal' From Colliding Black Holes Explained
The researchers demonstrated that the varying signal is likely generated by the motion of the two black holes.
