Ancient stars could make elements with more than 260 protons
The first stars of the universe were monstrous beasts. Comprised only of hydrogen and helium, they could be 300 times more massive than the sun. Within them, the first of the heavier elements were formed, then cast off into the cosmos at the end of t.....»»
Telescope tag-team discovers 10 strange and exotic pulsars
Towards the center of our Milky Way galaxy, in the constellation Sagittarius, astronomers have discovered 10 monstrous neutron stars. These particular stars, called pulsars, reside together in globular cluster Terzan 5, a crowded home for hundreds of.....»»
30 years ago, this action movie changed Hollywood forever. But was it for better or worse?
In 1994, a popular action movie starring one of the biggest stars changed Hollywood forever. 30 years later, Digital Trends asks if it was for better or worse......»»
Observatory gears up to detect thousands of elusive brown dwarfs, unlocking Milky Way mysteries
One could argue that brown dwarfs don't get the love they deserve. Sometimes referred to as "failed stars," they don't have enough mass to sustain nuclear fusion, which powers all stars, including our sun. But they are also too big to be considered p.....»»
Idiotfruit and tree kangaroos: Why the ancient rainforests of Queensland"s Wet Tropics are so distinctive
In Queensland's northern reaches lie the Wet Tropics, spanning about 450 kilometers between Townsville and Cooktown. These mountainous rainforests are a relic of the ancient continent of Gondwana, dating back million of years when Australia and parts.....»»
Did plague really decimate Neolithic farmers 5,200 years ago, as a new study suggests?
Around 5,200 years ago, plague was not just present but common in six generations of one Swedish family, according to a new study. The researchers analyzed both the ancient DNA of these people's skeletal remains and the pathogens that left traces in.....»»
How astronomers are using pulsars to observe evidence of dark matter
Tantalizing evidence of potential dark matter objects has been detected with the help of the universe's "timekeepers." These pulsars—neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space—were us.....»»

DNA analyses show the plague may have caused the downfall of Stone Age farmers
Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research.....»»
Astronomers find the nearest massive black hole, a missing link in massive black hole formation
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have long believed.....»»
