... 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. ...

... Section M-7 describes the basic problem of trigonometry (drawing on the left): finding the distance to some far-away point C, given the directions at which C appears from the two ends of a measured baseline AB. ... That means that the angle ? ... 2? r covers an angle 360њ . ... Suppose you want to estimate the distance to some distant landmark--e.g. a building, tree or water tower. ... Alpha Centauri, the sun-like star nearest to our solar system, has a distance of 4.3 years and a parallax of 0.75"....

This is a copy of a Press Release from E.S.O. Eight years after the passage of Comet Halley in early 1986, astronomers at the European Southern Observatory have succeeded in obtaining an image of this famous object at a distance of no less than 2,820 million km from the Sun. ... The image shows the 6 x 15 km avocado-shaped nucleus as an extremely faint point of light without any surrounding dust cloud. ... This observation was made with the ESO 3.58 metre New Technology Telescope (NTT). ...

... Our Galaxy . ... Universe . ... One of the Hubble Space TelescopeтАЩs goals was to accurately observe Cepheids in the most distant galaxies known (we knew they were far away, the problem was saying just how far). ... This work is becoming ever more refined; in January this year astronomers revealed that they had identified the farthest galaxy yet seen in a Hubble image. ... Thanks to the Hubble Space TelescopeтАЩs superb observations we can say that the universe is 13.75 billion years old. ...

... Kalirai and Harvey Richer of the University of British Columbia led the study, which began as an investigation of a globular star cluster in the Milky Way galaxy known as NGC 6397. ... Within the population of stars and galaxies behind NGC 6397, the Hubble image revealed a large elliptical galaxy that contains several hundred globular clusters. ... In fact, a single giant star in NGC 6397 appears 10 million times brighter than one of the distant globular clusters. ...

Ingredients of Life found in distant galaxy, Arecibo astronomers announce. Astronomers from Arecibo Observatory announced today at an American Astronomical Society meeting in Austin, TX, that they had found two of the basic ingredients of life in the distant galaxy Arp 220. The team used the 305-m Arecibo Radio Telescope, the world's largest and most sensitive, to observe the galaxy at a number of different frequencies. ...

... STScI-PRC01-04 HUBBLE'S ULTRAVIOLET VIEWS OF NEARBY GALAXIES YIELD CLUES TO EARLY UNIVERSE Astronomers are using these three NASA Hubble Space Telescope images to help tackle the question of why distant galaxies have such odd shapes, appearing markedly different from the typical elliptical and spiral galaxies seen in the nearby universe. ...

... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...
