Deep space bursts of energy commonly happen because of either supernovae or kilonovae. But in 2025, something else triggered a signal which lasted for seven hours. Scientists now have a theory about what could have happened.

Deep space signal that lasted 25,200 seconds gets a possible explanation

NASA recorded a signal that travelled from deep space over 13 billion years, and lasted merely 10 seconds. This discovery highlights several ignored aspects about the early universe, how time warps in space and how things really unfold in the universe.

10-second 'death cry' that took 13 billion years to reach Earth

Cosmic rays, not solar particles, shook the JetBlue flight that lost altitude in October, forcing Airbus to ground 6,000 more planes. A scientist says this is the most likely scenario and eerily similar to another incident recorded in 2008.

The mystery deepens. NASA tracks an unidentified red sphere moving at 283 miles per second, shattering every known galactic speed limit. This isn't just fast; it's impossible. We dive into the science behind the most mind-bending space discovery since the discovery of Comet 3I/Atlas.

For the first time ever, astronomers watched a massive star explode and captured its very earliest moments. This is the story of how we peered into the abyss and saw creation and destruction woven together on a cosmic stage.


Scientists witness earliest moments of a Supernova explosion

Scientists have captured the earliest moments of a supernova explosion, marking a historic milestone in astronomy. This first-ever snapshot provides unprecedented insights into the birth of a supernova, helping researchers better understand the life cycle of stars and the dynamics of cosmic explosions.

Historic First-Ever Supernova Snapshot Captured 

A strange gamma ray burst has baffled scientists who do not know what it is. It is unlike anything they have ever recorded. The cosmic event likely occurred billions of light years away, and the rays managed to reach Earth, implying it was extremely powerful. 

One star, multiple deaths? Mysterious gamma-ray burst that keeps repeating stumps scientists

Inside the heart of a star lies a powerful process that fuels the universe: nuclear fusion. Under immense pressure and extreme temperatures, hydrogen atoms fuse to form helium, releasing enormous amounts of energy. This process generates the heat and light we see from stars and keeps them from collapsing under their own gravity. Explore what happens deep inside a star’s core — where matter, energy, and gravity collide.

Supernova reveals its secrets, scientists see what's inside a dying star

The Nancy Grace Roman Space Telescope of NASA will go into operation in 2027 and will detect exploding stars in the ancient universe, going as far as 10 billion years. This means it will record the oldest supernova ever seen in the universe.

New NASA telescope will record 100,000 cosmic blasts, including stars that killed themselves 10 billion years ago

Astronomers have identified a binary white dwarf system, located just 150 light-years from Earth, that is expected to end in a rare quadruple supernova.

Two stars that died close to Earth likely triggered two mass extinctions on Earth, scientists suggest. Cosmic rays spelt doom for the planet. Science & Tech Trending

Cosmic explosions killed all life on Earth 445mn yrs ago and then again 73mn years later: Report

Stars have a life and death cycle. Those that are about eight times more massive than the Sun explode as supernovae at the end of their lives. They leave behind a black hole or a neutron star which are extremely bright, even more than their host galaxies.

A star in Andromeda died a silent death, giving birth to a cosmic mystery

Space is a mysterious and dangerous place. While we know that black holes can swallow up whole planets, some things are far scarier than them. Apart from black holes, various objects in the universe can pose a threat to not only our planet but the whole solar system.

If you think black holes are the most dangerous objects in space, you’re wrong

The James Webb Space Telescope has captured something remarkable - one supernova seen three times because of a twist in spacetime. This phenomenon is known as gravitational lensing.

Our universe is full of mysteries and wonder. While scientists and researchers keep discovering new phenomena and celestial objects, a much larger part of it remains unknown, which baffles scientists.

7 Unsolved Space Mysteries That Still Leave Scientists Scratching Their Heads

Astronomers have for the first time spotted a neutron star releasing a weird S-shaped jet, which looks like a "garden sprinkler". As per scientists, the S-shaped structure is created when the jet's direction changes because of the wobbling of the disk of hot gas near the star in a process known as precession.

This vampire star is shooting out 'garden sprinkler' like jets in cosmos. Here's why

According to the scientists, the night sky will soon get a "new star" or nova after a "once-in-a-lifetime" explosion. Although the explosion will not set the sky ablaze, it will give people a rare opportunity to see something they have never seen.

Sky to get a 'new star' after 'once-in-a-lifetime' explosion. Here's how to watch it

A new study has placed the focus on the watery planets which have been orbiting dead stars for a long time. According to the study, these white dwarfs - which are remnants of stars that have run out of fuel - may be the best place where life is being harboured due to the presence of water.

Scientists say watery planets orbiting dead stars may be hosting alien life

An unusual event took place in our cosmic space in the year 1975. The binary star system HM Sagittae (HM Sge) grew 250 times brighter and captured the attention of astronomers across the world.

This supernova remained brilliantly bright 40 years after its explosion

The James Webb Space Telescope (JWST) can be considered a cosmic detective which has been on the hunt for the explosive deaths of massive stars which occurred in the early universe.

In new research, scientists have found that elusive intermediate-mass black holes may have birthed in dense star clusters which are filled with tens of thousands to millions of tightly packed stars known as "globular clusters".

Intermediate-mass black holes have a 'birthing nest' in cosmic world, suggests study

An extraordinary surge of intense radiation took place across the solar system on October 9, 2022. This unprecedented phenomenon was promptly dubbed as BOAT (the Brightest of All Time) by astronomers and it captured immediate attention.

Shocking revelation! No Gold and Platinum formed by brightest supernova

How is a black hole formed? In the simplest language, a black hole is born when a star dies. Now, astronomers have claimed that they might have just witnessed the birth of such a black hole in a major first.

Missing link between a supernova and a black hole is finally revealed

Supernova are one of the universe's most cataclysmic events. If a planet is too close, it will be sterilised, even destroyed. When massive stars run out of nuclear fuel in their core, they produce x-rays and blast waves of fast particles that would render a planet like Earth uninhabitable. Watch this story to know how a star exploded 1.9 billion light-years away and our ozone layer took the hit.
