Astronomers say exploding stars might have forced our ancestors to walk upright

It’s a wild theory — but is it crazy enough to work?

Quasar measurements suggest the universe is expanding faster than we thought

We might need some new physics to explain how this is possible.

‘Zombie star’ cheats death again and again, dumbfounding scientists

A unique astronomical event is leaving many scientists scratching their heads.

For the first time ever, we’ve seen a black hole being silently born — no supernova required

Why blow up when you can mass up?

Awww, it has your….mass.

Superluminous supernovas explode twice, create some of the most powerful magnets in the universe

When a star is ready to drop the curtain, it goes out with a bang — a supernova explosion. But some double the bang.

Ancient supernovae might have contributed to Earth mass extinction

Death from the heavens.

Supernova shockwave recorded for the very first time

Some stars go out with a bang — a supernova explosion! Using optical images recorded by the now defunct Kepler telescope, astronomers witnessed for the very time the shockwave that follows a star’s implosion once it runs out of fuel.

Astronomers detect biggest explosion we’ve seen

The star was observed for the first time in June, but it’s still radiating massive amounts of energy, making it shine 570 billion times stronger than our Sun.

Exploding supernova ejects enough material to seed 7,000 Earths

Everything is made of stardust – but some things are made of more stardust than others. A new study has found that a single supernova is capable of producing large enough quantities of dust to create thousands of planets like Earth.

Supernova flings star out of the Milky Way – it’s the fastest moving star ever

Astronomers have discovered a star racing at a incredible pace of 2.6 million miles an hour (4.2 million kilometers an hour), making it the fastest moving star discovered thus far. It’s so fast that it should exit our galaxy and turn into an intergalactic rogue. It doesn’t stop here. Such celestial oddities are believed to be spurred in motion by the extreme gravitational tugs found in the vecinity of supermassive black holes, such as the one found at the core of the Milky Way. The new found road runner, however, was most likely flung outward by a Type Ia supernova, one of the most powerful and brightest bursts of energy in the universe. Little is know about such stellar explosions, and the hypervelocity star might submit some valuable clues.

Nova seen Expanding right from the Beginning for the First Time

Here’s something you don’t see everyday – for the first time, astronomers witnessed how a nova is formed right from the onset, capturing and detailing its expansion. The white dwarf turned nova is located someĀ 14,800 light-years away and its study is set to reveal many things about how novas form. The star is dead, long live the nova! Stars shine

Supernova study might change how speed of light in vacuum is measured

Einstein’s theories suggest that light can not travel faster than c, a constant equal to the speed of light in a vacuum, which is 299,792,458 metres per second (by definition) or about 186,282.4 miles per second. All of our standing physical models are based on this assumption, and so far this idea has yet to be proven wrong, despite the

Light from huge explosion 12 billion years ago reaches Earth

Intense light from a huge explosion (a gamma ray burst) that took place shortly after the birth of the Universe (12 billion years ago) has reached Earth, and was observed by researchers. Gamma Ray bursts are the strongest explosions since the Big Bang – in justĀ 10 seconds, they release more energy than our sun in its entire life time; read

Astronomers observe spinning neutron star suddenly slowing down

In a never-before seen feat, astronomers using NASA’s Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, something which can provide valuable clues to understanding these mysterious objects. Neutron stars Neutron stars are the cores of former high-mass stars, the remains of supernovae after the blow-up. As the core of the massive star is compressed during a
