... 2000 October 19 . The Farthest Explosion Yet Measured . ... What is known is that satellites across our Solar System reported on 2000 January 31 a tremendous explosion of gamma rays had occurred towards some previously uninteresting direction. ... The VLT not only recorded an optical counterpart , shown above , but also was able to estimate that the cosmologically-induced redshift was an astonishing 4.5 -- placing GRB000131 farther across the universe than any explosion so measured. ...

... connection points . ... The point P3 is the connection between the horizontal and vertical actuators and is the axis of rotation for the tail gunner motion. processing: survey/020204/reduc We can compute P3,P5 (the moveable points) in dome centerline coordinates if we have the actuator distances and we know the positions of the above connection points in dome centerline coordinates for a given position of the tertiary (say the nominal focus position).(see actuator distances to dome centerline ). ...

В конце приводится полезный словарь и абсолютно бесполезная библиография, содержащая множество неудачных устаревших книг. ... Такое издание вполне может оказаться для тысяч людей единственной книгой по астрономии, которую они прочтут. ... Астрономия для большинства жителей Земли наука о чем-то очень отдаленном. ...

... A theory suggests that a certain sub-class of gamma-ray bursts all have the same absolute magnitude. ... The author claims that this absolute magnitude is so different from that in the previous sample that this must belong to a new sub-class of gamma-ray bursts. ... To do this, there needs to be some feature in their spectra which correlates with their absolute magnitude. ... Consider a telescope which is continually monitoring a star, looking for transits due to planets orbiting this star. ...

HI Line Measurements of Eight Southern Pulsars . ... To derive their kinematic distances and to study the interstellar medium, we have measured 21-cm absorption and emission spectra in the direction of eight southern pulsars with the Parkes telescope . ... We present our absorption and emission spectra for these eight pulsars, derive kinematic distances and electron densities along their lines of sight where possible, and compare our results with previous work. ...

... The greater the distance, the smaller the parallax. ... That triangle has the same proportions as the much larger triangle ABC, and therefore, if the distance B'C to the thumb is 10 times the distance A'B' between the eyes, the distance AC to the far landmark is also 10 times the distance AB. ... The most distant objects our eyes can see are the stars, and they are very far indeed: light which moves at 300,000 kilometers (186,000 miles) per second, would take years, often many years, to reach them. ...

... 2006: . The distributions of radial ages and chemical compositions of the stellar population for several elliptical galaxies were measured from the BTA observations down to the record (to date) distances from the nucleus. ... Photometric distances were measured and peculiar radial velocities were determined for 3000 spiral galaxies from the 2MFGC catalog, compiled at the SAO RAS based on the 2MASS infrared sky survey. ...

Two groups are measuring distant supernovae with the goal of determining whether the Universe is open or closed by measuring the curvature in the Hubble diagram. The figure below shows both data sets: Perlmutter et al. (1997) and (1998) in black and Garnavich et al. (1997) in orange. The curves show a closed Universe (Omega = 2) in red, the critical density Universe (Omega = 1) in black, the empty Universe (Omega = 0) in green, and the steady state model in blue. ...

... Our Galaxy . Milky Way . ... Universe . ... Space Flight . ... Other galaxies are not moving away because they are recoiling in disgust from the Milky Way, but appear to be receding because the Universe is expanding. ... Observers in any galaxy will see every other galaxy as redshifted, so there is nothing special about the Milky Way. ... If the Universe is expanding today, that implies that in the past the galaxies would have been closer together and the Universe was much smaller than it is now. ...
