...furnace, such metals as vanadium, titanium, columbium, zirconium, and the platinum group, which have been difficult to study because of their very high melting points, can be melted into very pure alloys. Then, through X-ray photographs, significant students can be made of the individual peculiarities of molecular structure and other physical characteristics...
More important than all the others perhaps which astronomers in 1987 hope to discover is the question of the gas which fills the atmosphere. Mt. Wilson has reported that it contains titanium, hitherto unknown. During the year, it is hoped to discover how the gas got there, its purpose said its composition...
...spectrum of the stars Chi 2 Orionis and Chi Aurigae, Astronomers Walter S. Adams and Theodore Dunham Jr. of Mt. Wilson Observatory found four lines (one of them almost blotted out by the interference of Earth's atmosphere) which they identified as originating from the element titanium. The peculiar sharpness of the titanium lines indicated that the light had picked them up not from the stars but in its travel across the not quite empty gulfs of the galaxy. Thus titanium takes its place as the third metallic gas in interstellar space...
