text: Nonetheless, the Cat’s Eye is among the most intensely studied planetary nebulae in astronomy, and recent observations have shown that the bright inner core has an effective temperature of between 7,000K and 9,000K, while the outer halo is significantly hotter at about 15,000K. Spectroscopic studies have also shown that the extremely energetic central stars’ solar wind leaves the star at a speed of about 1,900 km/sec, and is blowing material out of the nebula at the rate of about twenty trillion tons per second.
