Eighth century carbon spike not from comet impact
The space rock would have to have been 100 kilometers across and 100 billion to 1,000 billion tons, leaving a disastrous impact not supported by geological or written records.
- Planetary Science
Old rover finds new evidence of water on Mars
Opportunity’s analysis of rocks at Endeavour crater reveals chemistry that could have supported life.
- Planetary Science
Dwarf planet Ceres gives off gassy water
Astronomers report observations that Ceres releases water molecules from two distinct spots on its surface.
- Cosmology
New supernova spotted in nearby galaxy
The galaxy M82 has given off a brilliant flash, which astronomers have confirmed as a type 1a supernova.
- Cosmology
Filament of cosmic web set aglow
Astronomers say they have glimpsed a brightly lit strand of the cosmic web, the universe’s underlying structure
- Astronomy
Rosetta spacecraft checks in with Earth
The spacecraft has successfully transmitted a signal to Earth, meaning that ESA controllers can now prepare Rosetta for its August rendezvous with comet 67P/Churyumov–Gerasimenko.
- Astronomy
Planet found around sun twin in star cluster
The exoplanet YBP1194b orbits a twin of the sun in the star cluster Messier 67. Astronomers found three planets orbiting stars in the cluster.

Tracking fireballs for science
Watching a meteor race across the night sky is a romantic experience. And now it can be a scientific one as well.
- Astronomy
Galaxies’ missing mass may hide in gas clouds
Vast reservoirs of previously undetected gas could account for much of galaxies’ matter, solving a cosmic mystery.
- Cosmology
From Dust to Life
In about 300 pages, this book sums up the history of all that matters — or at least everything made of matter — from the Big Bang to life on Earth.
