They find yearly modulation in their detected scintillation rate that matches what you would expect if the Earth were rushing through Galactic Dark Matter as it goes around the Sun. ... Significant! ... Certainly, at 8-sigma, it is easy to accept that there is modulation. ... Astronomers in general are extremely suspicious of any yearly modulations, as we have learnt from hard experience that it is an extremely common source of systematic error. ... Chandra Blog . ...

... They were evidently due to dense meteoroid concentrations within the Leonid stream. At those times, Comet 55P/Tempel-Tuttle's orbit was significantly nearer the Earth's orbit than at most perihelion returns, but still some tens of Earth radii away. ... Evaluation of differential gravitational perturbations, comparing meteoroids with comet, shows that in 1833 and 1966 respectively, the Earth passed through meteoroid trails generated at the 1800 and 1899 returns. ...

... Tiny Tim has been used for generating Hubble Space Telescope ( HST ) point-spread functions (PSFs) for deconvolution, algorithm testing, proposal planning, and optical studies. ... Tiny Tim is a stand-alone program for simulating HST PSFs as viewed with the on-board imaging cameras (WF/PC-1, WFPC2, FOC, COSTAR/FOC). ... The measured aberrations for FOC f/96, WF/PC-1 PC6, WFPC2, and COSTAR/FOC are used by Tiny Tim . ... Figure: FOC f/96 observed and Tiny Tim model PSFs (pre-COSTAR) at 253 nm. ...

Spectropolarimetry and modeling of Galactic Wolf-Rayet star WR156 O LGA M A RY E VA Special Astrophysical Observatory RAS; olga.maryeva@gmail.com For the first time spectropolarimetric observations of Wolf-Rayet star WR156 (WN8h sub-class) were conducted. ... This polarization is, most probably, has an interstellar origin, as its magnitude and orientation are similar to the ones of field stars. ... By its parameters WR156 is similar to other WN8h stars, displaying the line effect. ...

... If you could point a telescope anywhere in the sky, where would you look? The Personal Space web application allows you to make a direct and personal connection to the universe by linking significant events in your own life with what was above you in the sky at that moment. ... Personal Space is an online invitation to connect with and explore the universe in an intuitive way by presenting beautiful astronomical images of the sky overhead at key moments and places of personal significance. ...

ASTEROIDAL DAMAGE TO THE EARTH: IMPLICATIONS BY ASTEROIDS ­ RUBBLE PILES. ... 13, Moscow 119892, Russia, E-mail:san@sai.msu.ru In the cause of asteroids ­ rubble piles its effective cross-section of collision to the Earth is determined not by consolidated body, but by cluster of its fragments. Since the stage of rubble ­ piles may be ~108 years (see our communication at previous symposium), it may be significant for estimation the asteroidal damage to the Earth. ...

... For a semple of red giants comprising about 2000 stars, the distributions of metallicity [Fe/H] are given. ... The center of the distributions of giants in both galactic poles is found to demonstate a statisticaly significant gap similar to the one found earlier for the late main-sequence stars. The implications of the metallicity distribution properties for the problems of the chemical evolution of the galactic disk are discussed. ...
