Centaurus A in the spotlight: Plasma simulations reproduce black hole jets' mysterious bright edges
المصدر: Phys.org - latest science and technology news stories · نُشر
Around 12 million light-years away, the supermassive black hole of the galaxy Centaurus A is hurling two enormous plasma jets into space at nearly the speed of light. These so-called jets are brighter at their edges than at their center. The reason for this was previously unclear
Around 12 million light-years away, the supermassive black hole of the galaxy Centaurus A is hurling two enormous plasma jets into space at nearly the speed of light. These so-called jets are brighter at their edges than at their center. The reason for this was previously unclear but has now been explained by a team from the Chair of Astronomy at the University of Würzburg.
The research is published in the journal Astronomy & Astrophysics.

Roman-era 'frog feast' near Cambridge was the work of owls, bone analysis suggests
Around 1,800 years ago, over 9,000 bones, mainly from frogs, ended up in an Iron Age/Roman gully near Cambridge. When archaeologists first dug them up, speculation soon followed. Were these the remains of a Roman frog feast or perhaps the skeletal aftermath of a ritual?

A radical theory says the universe is twice as old as we thought
A provocative new cosmological model suggests the Universe could be 26.7 billion years old and might not need dark matter or dark energy to explain its behavior. University of Ottawa researchers tested the theory against several major astronomical observations, finding that it co

Comets may have destroyed life's ingredients instead of delivering them to Earth
A century-old theory about the origins of life on Earth may be wrong. New research from the University of Cambridge suggests that comets traveled too fast and struck at unfavorable angles for the fragile molecules needed for life to survive, making successful delivery extraordina
