Supernovae explosions may have left traces on our Earth

Recent findings suggest that relatively close supernovas could theoretically have triggered at least four disruptions to Earth's climate over the last 40,000 years. What happens in space may not always stay in space.

Exploding stars may have caused mass extinction on Earth

Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth.

Astronomers discover new class of cosmic explosions

Astronomers have found two objects that, added to a strange object discovered in 2018, constitute a new class of cosmic explosions. They share some characteristics with supernova explosions and gamma-ray bursts.

Astronomers spot the brightest supernova

Astronomers have spotted the brightest and most energetic supernova ever recorded. The event, known as SN2016aps, may have been the result of two stars merging and then exploding.

The story of a golden nugget

Follow the story of golden atoms from their birth in stellar explosions via incorporation into formation of our planet to their coming together in a golden nugget and appearance in the Earth's crust.

Betelgeuse is Continuing to Dim

The star will go supernova at the end of its life, but that’s not projected to happen for tens of thousands of years or so. However, the great dimming of Betelgeuse continues. 

Will Betelgeuse explode soon?

Betelgeuse in constellation of Orion is looking markedly faint, the faintest it has been for the 21st century. Betelgeuse is a nearby supernova candidate.  Its transformation into Type II supernova could occur 100,000 years from now… or tonight.

100,000 Supernovae Exploded Near the Core of the Milky Way

Data obtained by VLT showed evidence of massive stars bursts billions of years ago in the galaxy’s center. The more recent burst was so intense that resulted in 100,000 supernova explosions. These findings are inconsistent with our notions that stars formed continuously in our galaxy.

Subaru Telescope Sees 1800 Supernovae

Japanese astronomers have captured images of an astonishing 1800 supernovae. 58 of these supernovae are the scientifically-important Type 1a supernovae located 8 billion light years away and are known as ‘standard candles’ in astronomy.

Newly discovered supernova complicates origin story theories

Many supernovae show a gradual increase in the light they put out. But for ASASSN-18bt, you could clearly see there's something unusual and exciting happening in the early times - an unexpected additional emission.

Mysterious supernova explosion

Supernovae happen all the time, but this one was different. "Cow," as astronomers are calling it, was a massively bright explosion 200 million light years away.

New Mysterious Space Object Nicknamed "The Cow"

A mysterious cataclysm in a neighboring galaxy was spotted in the sky above Hawaii last week, sending astronomers around the world scrambling to understand the source of the staggeringly brilliant flash.

This Is the Most Distant Confirmed Supernova Ever Observed

On August 22, 2016, astronomers spotted a superluminous supernova whose light traveled over 10 billion years to reach us.

The Afterglow From Kilonova is Continuing to Brighten

Contrary to what was expected, a team of astronomers has discovered that kilonova event has been brightening ever since it first appeared.

The Star That Would Not Die

Astronomers have made a bizarre discovery; a star that refuses to stop shining.
