We summarize the week's science breakthroughs every Thursday.
- Space
Pioneer puzzle pinned on thermodynamics
Waste heat, not exotic physics, is slowing two 1970s-era space probes down more than would be expected, a new study claims.
- Space
Fermilab data hint at possible new particle
For the second time in weeks, results from powerful collisions of protons and antiprotons at Fermilab’s Tevatron accelerator can’t be explained with standard model of physics.
- Space
Atom & Cosmos
Planets’ rippled rings carry a record of past comet collisions, plus twin solar peaks and identifying elderly stars in this week’s news.
- Physics
Remodeling the standard model
Physicists could be on the verge of discovering a new elementary particle, studies at a U.S. accelerator suggest.
- Space
First portraits of Mercury from orbit
MESSENGER spacecraft to capture more than 1,500 images in three days.
- Space
First shot of Mercury from orbit
MESSENGER has radioed to Earth a new look at the first rock from the sun.
- Space
Atom & Cosmos
Dead stars may actually be a good place to hunt for life, plus organic-free asteroids and watery comets in this week’s news.
- Space
Planets take shape in embryonic gas clouds
A new theory of planetary formation may explain variety seen in extrasolar searches.
- Space
Atom & Cosmos
Ancient galaxies are found in a surprisingly full-grown state, plus stellar hearts and Mars’ rocky past in this week’s news.
- Space
Laser proposed to deflect space junk
A ground-based device would use light to push debris off a collision course.

MESSENGER eases into Mercury’s orbit
After three flybys, a NASA spacecraft settles in for a closer look at the first planet.
