Estimating the NEO Population and Impact Risk: Past, Present and Future . ... Since most of the risk resides in the largest impactors, finding that fraction of the largest bodies, and that none of them has a significant chance of impacting in the next century or so, "retires" more than 90 % of the impact risk, including most of the risk of a globally catastrophic impact event. ... In the mid-size range, from ~150 m to ~1 km, the main risk is from tsunami generated by an ocean impact. ...

So how do we find objects on the other side of the Universe? ... The latest instruments enable us to scan large areas of sky. Using Cerro Tololo's Blanco 4m telescope and the Canada-France-Hawaii 3.5 metre telescope , we are able to scan a piece of sky larger than the size of the moon every 5 minutes to a faintness level which allows us to find Type Ia supernovae halfway across the Universe. Type Ia supernovae are very rare - but each image we take contains 50000 galaxies. ...

Some Recent RR Lyra Measurements Taken From MRO . This RR Lyrae star (302129) was discovered by Scott Anderson and Armin Rest using imaging data from the Sloan Digital Sky Survey. The attached plot is a folded light curve of data taken by Brandon Lawton and Bridget Kaeding this summer (2000) with MRO (the open squares). ... Because both observatories caught this star on the rising branch, we can get the period quite accurately. ...
