Television Cameras Expand Study Of Heavens

Dr. Thornton Page of Yerkes reported at the American astronomical society meeting on a $15,000 television instrument for medical use with X rays that can be adapted for astronomy. The device lets astronomers capture and select star images at varying intensities and compile rapid sequence photographs. Dr. Olin J. Eggen described measuring stellar distances by color and brightness, noting some stars are hundreds of thousands of light years away. US and Mexican scientists hailed the Schmidt telescope for rapid wide-field photographs, reducing work from six hours to twenty minutes, with a naked-eye limit far surpassed by the instrument.

Football May Solve Mystery In Universe

The article reports a theory by Dr. Jesse L. Greenstein and Prof. Leverett Davis Jr. that spinning elongated dust particles containing iron could polarize starlight, supporting space magnetic fields. Their idea, presented at the 82nd AAS meeting, offers a physical mechanism for polarization and may revise astronomical concepts about interstellar dust and magnetism.

Interstellar Dust Spins Like Footballs Under Magnetic Field

Dr. Greenstein of California explains that rotating interstellar dust and gas particles could align in a magnetic field, causing polarization of starlight. He notes high gas temperatures near bright stars disrupt alignment through frequent particle collisions, yet spinning end over end may produce the observed effect.
