The earliest view (upper left) was taken 5 hours, 45 minutes before closest approach when the spacecraft was 164,000 kilometers (102,000 miles) from Gaspra. ...

... Bionic eyes. If our eyes could see in different wavelength bands, this is what the Sun would look like. ... Visible light, crucial to photosynthesis, is a type of radiation. ... At the heart of this revolution is the recognition that light travels as a wave. ... Dreams of Fields . ... By the time the fields go from strong to weak and back to strong, the wave has moved a certain distance, known as the wavelength. ...

... As an experiment, I made some three-color images of Messier 42, more commonly known as the Great Nebula of Orion. ... green enhanced . ... halfsize or fullsize . ... Each image is a ``true color'' composite of three monochromatic images, in which the red, green, and blue intensities each correspond to the intensity of one of the original images. ... The HST image is assembled from different filters than mine: red is Nitrogen [II] at 6583 , green is H-alpha at 6563 , and blue is O [III] at 5007 . ...

Next: A Universal Diagram for Up: ``Ecology'' of Magnetic Rotators Previous: The Corotation Radius . The interaction of a magnetic rotator with the surrounding plasma to a large extent depends on the relation between the four characteristic radii: the stopping radius, , the gravitational capture radius,   , the light cylinder radius,   , and the corotation radius,   . ... Hence, the classification of the interaction regimes may well mean the classification of magnetic rotators. ...

Target Acquisition Reference Information . Figure 7.1 on page 88 shows mean predicted count rates as a function of (B - V) 0 color for the four acquisition mirrors. Also shown are the fits to the predicted count rates for different amounts of reddening. ... You can estimate target acquisition count rates using the plots instead of Table 7.1 on page 92 : . ... Read from the Figures (depending on the mirror used) the predicted count rate. ...

... Bad Astronomy . Misconceptions . ... Bad Astronomy : The sky is blue because it reflects light from the oceans. Good astronomy : The sky is blue because it is scattering blue light from the sun. ... So everywhere you look you see blue photons, except directly from the Sun, where you'll see all colors. ... The sky does not look blue near the horizon because more yellow photons (and even orange ones right at sunset) are coming from that direction as they get scattered away from the Sun. ...

A visual impression of the data used in the study. The relevant extra-galactic maps are represented as shells of increasing distance from Earth from left to right. ... After this are six shells containing maps of the millions of distant galaxies used in the study. These maps are produced using different telescopes in different wavelengths and are color-coded to show denser clumps of galaxies as red and less dense regions as blue. There are holes in the maps due to data quality cuts. ...

... Most of the time large telescopes are collecting light for a spectrograph, which spreads the light out into a rainbow. ... Atoms in the cool outer layers of a star absorb light coming from the hotter regions within, producing dark absorption lines across the spectrum. ... And astronomers do not actually use color film to take a color picture of the spectrum, for several reasons: . ... Color film does a very poor job of representing the continuous range of colors in a spectrum. ... Tutorial: Part 1 |...
