Classroom Activity: Pinhole Protractor Gene Byrd and Renato Dupke . ... We cannot directly perceive the distances or sizes of far-away objects. Instead, our eyes only detect the angular size of objects. ... In Part II, which will appear in a future issue of The Universe in the Classroom, students will see how astronomers use parallax -- an extension of binocular vision -- to determine the distances of stars in the Sun's neighborhood. ... distance = 57.3 x physical size angular size (in degrees). ...

... Fix $s$ with $Re (s)=\sigma$, and let $\chi$ run over all Dirichlet characters with (say) prime conductors. Then (generally conjecturally), $M_{\sigma}(z)$ (resp. $\tilde{M}_{\sigma}(z)$) coincides with the limit-average over $\chi$ of $\delta_z(L'(\chi,s)/L(\chi,s))$ (resp. $\psi_z(L'(\chi,s)/L(\chi,s))$). Here $\delta_z(w)$ is the Dirac measure concentrated at $z$ and $\psi_z(w)=\exp(i Re(\bar{z}w))$ is the additive character on the field of complex numbers parametrized by $z$. ...

... Comparing observations more than a century apart, Hipparchus proposed that the axis around which the heavens seemed to rotate shifted gradually, though very slowly. Viewed from Earth, the Sun moves around the ecliptic, one full circuit each year. ... During an eclipse, Sun, Earth and Moon form a straight line, and therefore the center of the Earth's shadow is at the point on the celestial sphere which is exactly opposite that of the Sun. ... Some 2000 years after Hipparchus, in the year 1840. ...

We note, with deep sorrow, that Dr. Valentin Alexandrovich Lipovetsky, a senior astronomer and the leader of the Laboratory of Galaxy Studies of the Special Asrtrophysical Observatory, passed away at the age of 51 on September 22, 1996, after a several year battle with melanoma. Valentin Lipovetsky was an outstanding astronomer in many areas of extragalactic research and an internationally acknowledged leader in objective prism surveys and studies of AGN and star-forming galaxies. ...

... were entered in the atlas. ... In so doing lines were selected which yielded radial velocities close to the symbiotic velocity of MWC 560 (+35 km/s). ... The visible spectrum of MWC 560 is poor in absorption lines especially near the brightness maximum. In our atlas are visible only the blue-shifted components of , , NaI and FeII(42), interstellar lines NaI, a few diffuse interstellar bands (DIB) and telluric lines of and and, at length, traces of the spectra of the M giant. ...

If the mean distance of Earth from the Sun is 1 AU ("Astronomical Unit"), then that of Venus is 0.723 AU, of Mercury 0.387 AU and that of Mars is 1.524 AU. ... By noting (1) where on the Sun's disk is the crossing seen, (2) timing its duration at two far-apart points on Earth, and (3) comparing the times, one can calculate the distance to Venus and from it the scale of the solar system. ... One occurred in 1639--too early. ...
