IR and radio measurements that have revealed the presence of planets around other stars are reviewed. IRAS data on Vega indicated the object was 10-20 times as bright as it should be at 60-1000 microns, and elongations of 20 arcsec at those wavelengths suggests the presence of dust grains at least 1 mm diameter. A low-luminosity IR source has been sighted around T Tauri, and a condensing protoplanet has been suggested as a possible explanation. Millimeter wave observations of a cloud in Orion have revealed the presence of a disk 40,000 AU in diameter, and one 15,000 AU in diameter around L1551 in Taurus. Both objects are in a plane around a central, large, hot star, and fit previously devised models for a protoplanetary disk. Further measurements of the two radio disks will be made with the IRAS to confirm and elaborate on the data.
