This transmission electron microscopy image shows how the olivine (dark grey) hosts fine pure iron metal grains (white) with excellent magnetic recording properties. These metal grains are formed by reduction of an iron-bearing olivine precursor, which also produces excess silica (black phase at tips of metal grains) https://images.squarespace-cdn.com/content/v1/56d74e9c4c2f85996d16a562/1486935415428-KYZKW8843ZS9WT394WID/Solar_Nebula_M5b_cut_no_mh.jpg Home - LIFETIME OF THE SOLAR NEBULA We found that volcanic angrites are not magnetized, indicating that the solar nebular field and gas likely had dissipated by just 3.8 million years after the formation of the oldest known solids. http://www.benweiss.mit.edu/publications daily 0.75 2026-02-23 http://www.benweiss.mit.edu/about daily 0.75 2026-02-23 https://images.squarespace-cdn.com/content/v1/56d74e9c4c2f85996d16a562/1457195226567-LZDDL9ZNBVUY0EJEK94N/Weiss3_small.jpg About Me https://images.squarespace-cdn.com/content/v1/56d74e9c4c2f85996d16a562/1555799700735-KPXULXY569LBE4W3IEB1/Weiss_bodyshot_2019-04-20_lowres.jpg About Me https://images.squarespace-cdn.com/content/v1/56d74e9c4c2f85996d16a562/1457202177175-NLV3KBST35PZMLTMHK8J/MIT-logo-black-red-large.jpg About Me https://images.squarespace-cdn.com/content/v1/56d74e9c4c2f85996d16a562/1457202230034-11GWBFQHMPFJTJSYNPOZ/image-asset.png About Me http://www.benweiss.mit.edu/opportunities daily 0.75 2019-02-26 https://images.squarespace-cdn.com/content/v1/56d74e9c4c2f85996d16a562/1459712525548-A5YBBSJTAIQMWMT4Q9DE/Karin+drills+India_cut3.png Opportunities Former Harvard Ph.D. student Karin Louzada drilling basalts at Lonar crater, India. http://www.benweiss.mit.edu/psyche-magnetometer-research-scientist daily 0.75 2017-06-11 https://images.squarespace-cdn.com/content/v1/56d74e9c4c2f85996d16a562/1497210802287-JMQOSDLC0G93A7JIEFDG/PSYCHE_WIDESHOT_FINAL_ultra-low.png Research Scientist, Psyche Magnetometer Investigation http://www.benweiss.mit.edu/50th-birthday daily 0.75 2023-03-07
