RCW 88 of a larger halo of fainter nebulosity extending perhaps out to 10 arcmin. The RCW catalogue states the Hα image size is 3'×2. RCW 88 is located about 3300 parsecs (10,000 light years) from us, though other estimates place this at a closer 1800±300 pc. or 1800±200 pc. Assuming the former distance and the diameter as 5'-6' across, finds by simple trigonometry the true size subtends a minimum of 5±1 parsecs (16±3 light-years.) This small emission nebula shows a mean radial velocity of −18 km.s, and is also a faint radio source that was identified by Lloyd Higgs in 1971.
Penske PC-26 Penske PC-26 The Penske PC-26 was designed by Nigel Bennett and manufactured by Penske Cars in Poole, Dorset, for the 1997 CART Championship. Whilst a development of the PC-25, the PC-26 was designed to address the twitchy nature of the previous year's car. Five chassis were produced and driven by Al Unser Jr and Paul Tracy. The Ilmor-produced 850 bhp Mercedes-Benz IC108D engine served as the powerplant, driving through an Xtrac gearbox within a Penske housing. Aerodynamic changes from the previous year's car included revised sidepod inlets and a longer, sharper nose. The Delco Gen V electronics package was carried
