... Observations of the Moon eclipse on 17.09.97 have shown the Moon details contrasts had decreased and the total radio brightness had fallen at all observed frequency range (from 10% at 1.38 sm down to 2.5% at 13 sm). The fall of the Moon radio brightness has been detected during the eclipse at decemeter waves for the first time. ... Radio emission of the Copernicus crater at 1.38 and 2.7 sm has been detected for the first time. ...

You Can Make Stellar Images Brighter . Articles | ... A few months ago I wrote an article titled "You Can’t Make Them Brighter". So why am I now writing that you can make them brighter. ... The image of a focused star is actually a small disk called the Airy disk, named after the 19 th century scientist Sir George Airy. ... For a given aperture, a smaller Airy disk means that the light is focused to a smaller disk and is therefore brighter. ... www.astronomy.net . About Astronomy Net | ...

... Press Release Images . Individual Images . ... The right-hand image shows Hubble's close-up view of the galaxy's core, taken in December 1995 by the Wide Field and Planetary Camera 2. The bluish-purple clumps that form the ring are the clusters of infant stars. Two dark, wispy lanes of dust and a pair of blue spiral arms are just outside the star-forming ring. ... The gas is trapped inside the ring through the stars' gravitational attraction. ... Amazing Space | ...

... X-ray sources in galaxies: active nuclei, primodal black holes or microquasars . The last findings in observations of point-like X-ray sources in galaxies are reported. ... A new class of objects has been discovered - the Ultraluminous X-ray (ULX) sources, which could be as black holes of intermediate mass (100-1000 suns), being captured by galaxies and spiralling in because of dynamical friction, or microquasars (SS433-like stars), being orientated "face-on". ...

... The time taken to read through a quadrant on the array sets a fundamental limit on the fastest electron collection rate which can be achieved by resetting all the pixels. An inherent consequence of the methods of operating the NICMOS array detectors in the ACCUM, MULTIACCUM, and RAMP modes is therefore that there is a minimum possible exposure time, ~ 0.6 seconds (0.302 for MULTIACCUM), set by the time required to read the array. ... Figure 15.1 illustrates the operation of bright object mode. ...

... Its perihelion would occur on April 1, 1997, at which point the comet would be only 0.92 astronomical units from the Sun, just within the orbit of Earth. ... Taken in April 1993, the photo showed the comet over 13 astronomical units from the Sun, well beyond the orbit of Saturn. ...

This animation shows a binary star being lensed by a binary lens. ... The sharp changes in the size of the lensed images of the stars lead to sharp changes in the brightness of the stars, which can be analyzed to determine many parameters about the objects doing the lensing, even though they are not bright enough to be seen. ... The graph shown above gives the predicted and observed brightness of a star in the Small Magellanic Cloud being magnified by a binary lens. ... Tutorial : Part 1 | ...

From: TerryMosel aol.com Date: Sun, 6 Jun 2004 13:44:21 EDT Subject: Venus on SOHO, next transits Hi all, Venus is still very bright on the LASCO C3 images, even though the phase is only 0.001! ...

... What's New? Bad Astronomy . ... the ISS will eventually be the brightest object in the night sky and the only artificial heavenly body visible to the naked eye. ... That position is held by the Moon, which will shine something like 20,000 times brighter than the ISS at worst. Venus is second, which is roughly 2-5 times brighter than ISS. ... ISS will be among the brightest of these, but the doomed Iridium satellites get brighter, and Mir, the ISS's predecessor, can get brighter as well. ...

... This task takes an event list and makes an image in which the value in each pixel is proportional to the variability with respect to time of the flux of events which fall within that pixel. The task cycles through all the events in the list which fall within the spatial extent of the image; for each of these events, a value of the Kolmogorov-Smirnov statistic is calculated. ... Note the implication that pixels having zero variability are not zero-valued in the output image. ...

... Stars are born in big clouds of gas and dust in the Universe. ... This amazing new picture shows a small part of a cloud in our own galaxy (called the Milky Way) in which stars are being formed.

... The ancient chronical said about the colour rings around the Sun and the Moon, about three suns in the sky, light columns, bright lightning, different "comets" rushing to the Earth, moving among the stars or round the Earth with the sky. All these occurrences may be divided into three categories: one that occur in the near or far space, processes going on in the Earth atmosphere under the influence of cosmic factors and at last the occurrences connected with the Earth atmosphere. ...
