Luminous features pointing at the spiral galaxy NGC 1097 were discovered with the U.K. 48 inch (1.2 m) Schmidt telescope. A series of deep, high-resolution photographs have now been taken with the 4 meter CTIO reflector in Chile. These plates show (1) three luminous jets, two of which are aligned in exactly opposite directions, and all of which emanate exactly from the center of NGC 1097; (2) that where the jets pass through the spiral arms of NGC 1097, they disrupt the gaseous component of those arms.The present photographic observations enable an age of 10/sup 7/ years and an ejection velocity of 5,000 km s/sup -1/, or greater, to be computed for the jets. The material of the jet consists of some compact bodies, possibly some plasma from the parent galaxy, and possibly some plasma and/or material given off from the ejecta in its outward passage through the galaxy. It is calculated that special circumstances make these particular jets visible and imply that many spiral galaxies may be similarly ejecting. (AIP)
