By precisely timing the LIDAR ' echo ,' and by measuring how much laser light is received by the telescope, scientists can accurately determine the location, distribution and nature of the particles.

The difference between the line-of-sight of the operator's telescope and the missile's flare was calculated by the computer in the base of the launcher, and guidance updates sent to the missile over the guidance link, received on small antennas on the rear of the mid-body fins.

She received the prize, an amateur telescope, during the inauguration of the Paranal site.

This report was issued in October 1608 and distributed across Europe, leading to experiments by other scientists, such as the Italian Paolo Sarpi, who received the report in November, the Englishman Thomas Harriot, who was using a six-powered telescope by the summer of 1609, and Galileo Galilei, who soon improved the device.

The first radio telescope to give output automatically in printed form, and therefore capable of worldwide dissemination by teleprinter, its daily solar weather maps received acknowledgement from NASA for support of the first manned landing on the moon.

Other objects can be observed using CCD cameras or photoelectric photometers connected to a telescope, and the flux, or amount of light received, can be compared to a photometric-standard star to determine the exact brightness, or stellar magnitude, of the object.

The major portion of the data was received by the Lovell radio telescope at Jodrell Bank Observatory and the Hawaii Tracking Station because their antennas provided grid reception.

Controllers received indications that both antennas had nested properly against the body of the telescope, but microswitches on two latches of one antenna and one latch on the other did not send the " ready to latch " signal to the ground.

In 1911, Carnegie became a sympathetic benefactor to George Ellery Hale, who was trying to build the 100 inch ( 2. 5 m ) Hooker Telescope at Mount Wilson, and donated an additional ten million dollars to the Carnegie Institution with the following suggestion to expedite the construction of the telescope: " I hope the work at Mount Wilson will be vigorously pushed, because I am so anxious to hear the expected results from it.

Additional ground-based instruments such as the South Pole Telescope in Antarctica and the proposed Clover Project, Atacama Cosmology Telescope and the QUIET telescope in Chile will provide additional data not available from satellite observations, possibly including the B-mode polarization.

Smyth moved to Stone near Aylesbury in 1842, and still had the opportunity to use the telescope since his residence at St. John's Lodge was not far from its new location, and he performed a large number of additional astronomical observations from 1839 to 1859.

During the next decade, two additional repair missions were made ( March 2002 and in May 2009 ), eventually bringing the telescope to even better that its initially intended performance.

They argued that the telescope should ultimately be under the control of the Director of Mount Stromlo and Siding Spring Observatories and that additional staff for the new telescope should be provided by the ANU.

Additional ground-based instruments such as the South Pole Telescope in Antarctica and the proposed Clover Project, Atacama Cosmology Telescope and the QUIET telescope in Chile will provide additional data not available from satellite observations, possibly including the B-mode polarization.

about 20 ( from the bigger telescope ) × 25 ( for better seeing ) = 500 × in return signal strength over MLRS, and additional factor of 25 in

Taking data at different times provides measurements with different telescope separations and angles without the need for buying additional telescopes or moving the telescopes manually, as the rotation of the Earth moves the telescopes to new baselines.

Solar panels on the telescope would provide additional power, allowing an extended mission of 21 – 28 days.

The telescope module would include a pressurized compartment providing additional living and workspace for the crew.

When the 1. 8m telescope addition are complete, NPOI also will undertake additional studies of dust and proto-planetary disks, and planetary systems and their formation.

In 2007, using the Keck telescope, a team from California Institute of Technology found six star forming galaxies about 13. 2 billion light years ( light travel distance ) away and therefore created when the universe was only 500 million years old.

The four moons were discovered sometime between 1609 and 1610 when Galileo made improvements to his telescope, which enabled him to observe celestial bodies more distinctly than had ever been possible before.

Actual proof of the Milky Way consisting of many stars came in 1610 when the Italian astronomer Galileo Galilei used a telescope to study the Milky Way and discovered that it is composed of a huge number of faint stars.

These views were forcefully expressed by David Hilbert in 1928, when he wrote in < cite > Die Grundlagen der Mathematik </ cite >, " Taking the principle of excluded middle from the mathematician would be the same, say, as proscribing the telescope to the astronomer or to the boxer the use of his fists ".

Project Argus instruments typically exhibit sensitivity on the order of 10 < sup >− 23 </ sup > Watts / square metre, or roughly equivalent to that achieved by the Ohio State University Big Ear radio telescope in 1977, when it detected the landmark " Wow!

The term for this class of objects is a partial misnomer that originated ( 1784 or 1785 ) with astronomer William Herschel, because when viewed through his telescope, these objects appeared to be clouds ( nebulae ) that were similar in appearance to Uranus, the planet that had been discovered telescopically by Herschel.

An amateur radio operator, Grote Reber, was one of the pioneers of what became known as radio astronomy when he built the first parabolic " dish " radio telescope ( in diameter ) in his back yard in Illinois in 1937.

In observational astronomy, a double star is a pair of stars that appear close to each other in the sky as seen from Earth when viewed through an optical telescope.

Convection causes the temperature and hence the refractive index of the air to vary, and so a blurred shimmering effect is produced which affects the ability to resolve objects, the effect being increased when the image is magnified through a telescope or telephoto lens.

Telescope domes have a slit or other opening in the roof that can be opened during observing, and closed when the telescope is not in use.

They are particularly useful when the spacecraft must be rotated by very small amounts, such as keeping a telescope pointed at a star.

It, when completed, will be the largest binocular telescope in the world.

A breakthrough in astronomical photography came in 1883, when amateur astronomer Andrew Ainslie Common used the dry plate process to record several images of the same nebula in exposures up to 60 minutes with a 36-inch ( 91 cm ) reflecting telescope that he constructed in the backyard of his home in Ealing, outside London.

Each individual telescope can detect objects roughly four billion times fainter than what can be detected with the naked eye, and when all the telescopes are combined, the facility can achieve an angular resolution of about 0. 001 arc-second.

In his autobiography given to the Nobel Prize Committee, he recalled, " The first stirrings of interest in science that I remember occurred during a moment of boredom at religious school, when, looking out of the window at twilight through a hand curled to simulate a telescope, I noticed something peculiar about the light ; it was the phenomenon of diffraction.

The 50 ft telescope was demolished in 1982, when it was replaced with a more accurate telescope named the " 42 ft " following an accident that irreparably damaged the 50 ft telescope's surface.
