Ancient star system reveals Earth-sized planets forming near start of universe
A Sun-like star with orbiting planets, dating back to the dawn of the Galaxy, has been discovered by an international team of astronomers.
A simulation of the universe with realistic galaxies
An international team of astronomers, based at the Universities of Leiden in the Netherlands and Durham in the UK and, led by professor Joop Schaye (Leiden University), developed a simulation of the universe ...
Researcher explores how the universe creates reason, morality
Recent developments in science are beginning to suggest that the universe naturally produces complexity. The emergence of life in general and perhaps even rational life, with its associated technological ...
Video: What is the biggest thing in the universe?
Think big. Really big. Like, cosmic big. How big can things in the Universe get? Is a galaxy big? What about a supercluster? What is the biggest thing in the Universe?
Why is Andromeda coming toward us?
I don't want to alarm you, but there's a massive galaxy heading our way and will collide with us in a few billion years. But aren't most galaxies speeding away? Why is Andromeda on a collision course with ...
'Assassin' targets supernovae in our neighborhood of the universe
While many astronomical collaborations use powerful telescopes to target individual objects in the distant universe, a new project at The Ohio State University is doing something radically different: using ...
The cosmic seeds of black holes
Supermassive black holes with millions or billions of solar-masses of material are found at the nuclei of most galaxies. During the embryonic stages of these galaxies they are thought to play an important ...
Calculating the future of solar-fuel refineries
A team of University of Wisconsin-Madison engineers has developed a new tool to help plot the future of solar fuels.
A new, public view of the sky
For the first time, scientists and the public are beginning to see the large-scale structure of the universe, thanks to the Sloan Digital Sky Survey. UA scientists provide scientific expertise and crucial ...
Best of Last Week – New explanation for dark matter, a simulation of the universe and the randomness of cancer
Why moving from astronomic to atomic time is a tricky business
Most people would feel they can count on one day comprising the same number of hours, minutes and seconds as the next. But this isn't always the case – June 30 will be a second longer in 2015 with the addition of a leap second, ad ...
Seeking cracks in the Standard Model
In particle physics, it's our business to understand structure. I work on the Large Hadron Collider (LHC) and this machine lets us see and study the smallest structure of all; unimaginably tiny fundamental partic ...
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.
Cool crystals and hot climates
A crystalline structure used by a silkworm virus to protect itself from the elements may provide similar protection for human vaccines in challenging tropical climates and remote regions.
