Kepler's New Astronomy

This year (2009) is the 400th anniversary of the publication of Johannes Kepler's book New Astronomy (Astronomia Nova) announcing the discovery of the elliptical orbit of Mars to the world. The discovery of the elliptical orbit of Mars and the mathematical rule of motion for Mars on its elliptical orbit by Johannes Kepler in 1605 is one of the most important advances in astronomy, physics, and ...

ASTRONOMY AND ASTROPHYSICS New infrared

We present optical spectra for new infrared Seyfert galaxies obtained with the 2.16m telescope at Beijing Astronomical Observatory (BAO). After wavelength and flux calibration, they are classified by the degree of nuclear activity: nine Seyfert 2 and three Seyfert 3 galaxies. In addition, by using the data from de Grijp et al.(1992), we find that (1) there exists a tight correlation between lum...

Onics and the New Astronomy

In 1964 a panel concerned with astronomical facilities prepared a report for the National Academy of Sciences covering a ten-year program for groundbased astronomy. This report emphasized the shortage of ground-based optical facilities and projected the increasing inadequacy of observing resources. I t also pointed out the urgency of improving the operating effectiveness of the telescopes in ex...

VHE Astronomy before the New Millennium

In planning this workshop the organizers suggested that a review of new TeV γ-ray observations at the beginning might obviate a need for separate submissions from individual groups (which would be presented anyway at the ICRC) and thus permit the program to be devoted to technical developments, interpretations and new programs. In practice, this did not work too well since many groups wished to...
