Active galaxies point to new physics of cosmic expansion

Investigating the history of our cosmos with a large sample of distant 'active' galaxies observed by ESA's XMM-Newton, a team of astronomers found there might be more to the early expansion of the universe than predicted ...

Astronomers glimpse supernova shockwave

Astronomers have captured the earliest minutes of two exploding stars and for the first time seen a shockwave generated by a star's collapsing core.

A new technique to gauge the distant universe

Scientists have developed a technique to use quasars – powerful sources driven by supermassive black holes at the centre of galaxies – to study the universe's history and composition. To demonstrate the new method, based ...

Supernova twins: Making standard candles more standard than ever

Less than 20 years ago the world learned that the universe is expanding ever faster, propelled by dark energy. The discovery was made possible by Type Ia supernovae; extraordinarily bright and remarkably similar in brightness, ...

Supernova ignition surprises scientists

Scientists have captured the early death throes of supernovae for the first time and found that the universe's benchmark explosions are much more varied than expected.

What's happening in the universe right now?

There are some topics that get a little frustrating in their pedantry, but can really draw attention to the grand scope and mechanics in our Universe. This is definitely one of them.

Gaia discovers its first supernova

(Phys.org) —While scanning the sky to measure the positions and movements of stars in our Galaxy, Gaia has discovered its first stellar explosion in another galaxy far, far away.

Chandra observatory searches for trigger of nearby supernova

(Phys.org) —New data from NASA's Chandra X-ray Observatory offer a glimpse into the environment of a star before it exploded earlier this year, and insight into what triggered one of the closest supernovas witnessed in ...

Powerful ancient explosions explain new class of supernovae

Astronomers affiliated with the Supernova Legacy Survey (SNLS) have discovered two of the brightest and most distant supernovae ever recorded, 10 billion light-years away and a hundred times more luminous than a normal supernova. ...
