Aliphatic hydrocarbons on Ceres' surface found to have short lifetimes
A team of astrophysicists from several institutions in Italy, working with a colleague in the U.S., has found that aliphatic hydrocarbons observed on Ceres' surface have short lifetimes, suggesting they likely appeared there ...
Dark matter could have slight interaction with regular matter, study suggests
The reason we call dark matter dark isn't that it's some shadowy material. It's because dark matter doesn't interact with light. The difference is subtle, but important. Regular matter can be dark because it absorbs light. ...

The universe is smoother than the standard model of cosmology suggests. So is the theory broken?
Given how unfathomably large the universe is, it is perhaps understandable that we haven't yet cracked all its secrets. But there are actually some pretty basic features, ones we used to think we could explain, that cosmologists ...

Scientists create model of holographic dark energy that is no longer unstable
In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills up all of existing space-time ...

Can the 'hard steps' in the evolutionary history of human intelligence be recast with geological thresholds?
What took so long for humans to appear on Earth? The Earth is 4.6 billion years old, and life began about 4 billion years ago, yet humans—the only intelligent, technological species we know of in the universe—have existed ...
How special is the Milky Way galaxy? Survey team releases new findings
Is our home galaxy, the Milky Way galaxy, a special place? A team of scientists started a journey to answer this question more than a decade ago. Commenced in 2013, the Satellites Around Galactic Analogs (SAGA) Survey studies ...

Study shows Mars' early thick atmosphere could be locked up in the planet's clay surface
Mars wasn't always the cold desert we see today. There's increasing evidence that water once flowed on the red planet's surface, billions of years ago. And if there was water, there must also have been a thick atmosphere ...
