Allegheny Observatory - Current Work

Current Work

The main active research pursuit at the Allegheny Observatory involves detections of extrasolar planets. This is done using photometry, which is the practice of measuring the brightness of stars. The brightness of a target star and its close neighbors are measured on digital images taken every 30-60 seconds, and if a planet crosses (transits) in front of its parent star's disk, then the observed visual brightness of the star drops a small amount. The amount the star dims depends on the relative sizes of the star and the planet. The research team consists of students at the University of Pittsburgh whose observations have recently contributed to a collaborative effort to observe a transit of the planet HD 80606 b. The group is also actively contributing to upgrading the Allegheny Observatory.

In 2009, the university's Department of Geology and Planetary Science installed Western Pennsylvania's only seismic station, which is connected to IRIS Consortium networks, in the observatory.

Famous quotes containing the words current and/or work:

    I have come to believe ... that the stage may do more than teach, that much of our current moral instruction will not endure the test of being cast into a lifelike mold, and when presented in dramatic form will reveal itself as platitudinous and effete. That which may have sounded like righteous teaching when it was remote and wordy will be challenged afresh when it is obliged to simulate life itself.
    Jane Addams (1860–1935)

    ‘Tis not need we know our every thought
    Or see the work shop where each mask is wrought
    Wherefrom we view the world of box and pit,
    Careless of wear, just so the mask shall fit
    And serve our jape’s turn for a night or two.
    Ezra Pound (1885–1972)
