Forming Amino Acids in Interstellar Space March 29, 2002 | In two papers published in this week's Nature, scientists have come closer to understanding if amino acids are created in space. While these molecules clearly form on Earth today, some cosmochemists believe that the first fundamental building blocks for life…

Does the Moon Have a Titanium Heart? March 12, 2002 | It’s taken cosmochemists decades to convince themselves that the Moon has a small metallic core (Sky & Telescope, August 1999, page 17). But that conclusion is not without its problems. For example, a recent reanalysis of "moonquakes" recorded on…
A Bright Comet Returns — 341 Years Later
Independently discovered by two amateur skygazers, Comet Ikeya-Zhang is now passing near Earth on its first return visit since the time of Sir Isaac Newton.

Sun Spews Massive Bubble into Space February 22, 2002 | Our star unleashed a titanic coronal mass ejection, or CME, on February 18th. Containing billions of tons of matter, the superheated blast was captured by an extreme-ultraviolet camera aboard the orbiting Solar and Heliospheric Observatory. Fortunately, the outburst was directed…

A Solar-System Signpost? February 15, 2002 | Some young stars are surrounded by disks of dust left over from their formation. Eventually this material may coalesce into planets. But some older stars have dust disks too. Astronomers think these may be produced by collisions among comets, asteroids, and meteoroids in…
