Figure 1: Jetting of melted material during an accretionary impact. An important aspect of our model is that, although chondrules accumulate to form chondrites on small bodies, the chondrules ...

Figure 1: Abundance ratios of noble gases. In order to investigate the trapping site of subsolar gas in Yamato-791790, we performed a laser-microprobe noble-gas analysis. We prepared five polished ...

A normally staid scientist has stunned many of his colleagues with his radical solution to a 135-year-old mystery in cosmochemistry. At issue is how numerous small, glassy spherules had become ...

You and I got here by way of the stars. They fused simple elements like hydrogen and helium in their cores into more complicated ones like carbon, oxygen, nitrogen, phosphorus and iron crucial for ...

The millimeter-sized, sometimes glassy spheroids called chondrules that occur abundantly in stony meteorites may have been produced by lightning in the primitive Laplacian-type nebula while earthy ...

Chondrules are visible as round objects in this image of a polished thin section made from the Bishunpur meteorite from India. The dark grains are iron-poor olivine crystals. This is a backscattered ...

Round chondrules visible in a thin section of the Allende meteorite under microscopic view.
