Spectroscopic observation of nova ejecta nebulae has shown that they are enriched in elements such as helium, carbon, nitrogen, oxygen, neon and magnesium.

Spectroscopic analysis of HD 209458 b, an extrasolar planet in this constellation has provided the first evidence of atmospheric water vapor beyond the solar system, while extrasolar planets orbiting the star HR 8799 also in Pegasus are the first to be directly imaged.

As part of the company's growing homeland security business and strategic focus, Raytheon has teamed with other contractors to develop an Advance Spectroscopic Portal ( ASP ) to allow border officials to view and identify radioactive materials in vehicles and shipping containers more effectively.

Slater describes the dedication of the Laboratory, the hosting of meetings of the International Astronomical Union, the American Physical Society, and a Spectroscopic conference, and ends: " In general the year has been one of settling down to work under satisfactory conditions, after the more difficult transition of the preceding year.

Spectroscopic examination of this star shows that it has a higher abundance of elements heavier than helium ( or metallicity, as astronomers call it ) than does the Sun.

The galaxy has been studied with most of NASA's telescopes, including the Spitzer Space Telescope, the Chandra X-ray Observatory, and the Far Ultraviolet Spectroscopic Explorer ( FUSE ).

Spectroscopic analysis has shown that some of these asteroids are now located in the 9 / 4 mean-motion resonance with Jupiter.

CGRO recorded only about 77 events in 10 years ; however, more recently the Reuven Ramaty High Energy Solar Spectroscopic Imager ( RHESSI ) spacecraft, as reported by David Smith of UC Santa Cruz, has been observing TGFs at a much higher rate, indicating that these occur about 50 times per day globally ( still a very small fraction of the total lightning on the planet ).

Spectroscopic observations of their doppler shifts indicate velocities of several hundred kilometres per second, but the emission lines in the spectra of HH objects are too weak to have been formed in such high speed collisions.

Spectroscopic studies first revealed the presence of a planet around HD 209458 on November 5, 1999.

Spectroscopic studies first revealed the presence of a planet around HD 209458 on November 5, 1999.

Spectroscopic observations suggested that Io's surface was devoid of water ice ( a substance found to be plentiful on the other Galilean satellites ).

This project was known as Small Main-belt Asteroid Spectroscopic Survey, Phase II or SMASSII, which built on a previous survey of the main-belt asteroids.

Bus and Richard P. Binzel in 2002, based on the Small Main-Belt Asteroid Spectroscopic Survey ( SMASS ) of 1447 asteroids.

Spectroscopic studies were central to the development of quantum mechanics and included Max Planck's explanation of blackbody radiation, Albert Einstein's explanation of the photoelectric effect and Niels Bohr's explanation of atomic structure and spectra.

Among the Laboratory's current major active projects are the Mars Science Laboratory mission ( which includes the Curiosity rover ), the Cassini – Huygens mission orbiting Saturn, the Mars Exploration Rovers ( Spirit and Opportunity ), the Mars Reconnaissance Orbiter, the Dawn mission to the dwarf planet Ceres and asteroid Vesta, the Juno spacecraft en route to Jupiter, the Gravity Recovery and Interior Laboratory ( GRAIL ) mission to the Moon, the Nuclear Spectroscopic Telescope Array ( NuSTAR ) X-ray telescope, and the Spitzer Space Telescope.

Spectroscopic observations of HH objects show they are moving away from the source stars at speeds of 100 to 1000 km / s.

Spectroscopic examination of the energy states in the outflow of matter from the companion star suggest that it is about 224 AU behind the primary, giving a combined separation of about 574 AU.

Spectroscopic studies revealed absorption lines in the Jovian spectrum due to diatomic sulfur ( S < sub > 2 </ sub >) and carbon disulfide ( CS < sub > 2 </ sub >), the first detection of either in Jupiter, and only the second detection of S < sub > 2 </ sub > in any astronomical object.

Spectroscopic observers found that ammonia and carbon disulfide persisted in the atmosphere for at least fourteen months after the collisions, with a considerable amount of ammonia being present in the stratosphere as opposed to its normal location in the troposphere.

Spectroscopic measurements of the strength and width of these lines allow the composition and physical properties of a substance to be determined.

Spectroscopic measurements revealed common radial velocities, thus showing that the clusters consist of stars bound together as a group.

Spectroscopic data is often represented by a spectrum, a plot of the response of interest as a function of wavelength or frequency.

Spectroscopic studies are designed so that the radiant energy interacts with specific types of matter.

Spectroscopic observations thus showed that nebulae were made of extremely rarefied gas.

Spectroscopic observations show that all planetary nebulae are expanding.

* According to estimates released in October 2007, the Far Ultraviolet Spectroscopic Explorer ( FUSE ) space telescope, decommissioned that month, will continue orbiting the earth until it burns up in the atmosphere approximately 30 years after its decommissioning.

Spectroscopic analysis is commonly carried out in solutions but solids and gases may also be studied.

The science operations activities directly serve the astronomy community, primarily in the form of HST ( and eventually JWST ) observations and grants, but also include distributing data from other NASA missions ( e. g., Far Ultraviolet Spectroscopic Explorer, Galaxy Evolution Explorer ) and ground-based sky surveys.

Other uses of the term parallax in astronomy, with different meanings are the Photometric parallax method, Spectroscopic parallax, and Dynamical parallax.

* Kodak Spectroscopic Plate Type 649-F is specified with a resolving power of 2000 lines / mm.

However these mechanical systems were slow, the images were dim and flickered severely, and the image resolution very low.

The electron beam could be swept across the screen much faster than any mechanical disc system, allowing for more closely spaced scan lines and much higher image resolution, while slow-fade phosphors removed image flicker effects.

Whilst providing a projected image, the technique has limited resolution ( 2-2. 5 nm ), due to both quantum mechanical effects and lateral variation in electron velocity.

As a consequence of the Nyquist – Shannon sampling theorem, any spatial waveform that can be displayed must consist of at least two pixels, which is proportional to image resolution.

This effectively triples the horizontal resolution of the image at normal viewing distances ; but the drawback is that the line thus drawn will show color fringes ( at some points it might look green, at other points it might look red or blue ).

A crystalline solid: atomic resolution image of strontium titanate.

With some implementations, image resolution may be less directly limited by bandwidth ; for example in DVB-T, broadcasters can choose from several different modulation schemes, giving them the option to reduce the transmission bitrate and make reception easier for more distant or mobile viewers.

Generally, the image resolution of an SEM is about an order of magnitude poorer than that of a TEM.

Recently, with the development of digital intermediate ( DI ), it has become possible to completely edit, composite visual effects, and color grade the image digitally at full resolution and bit-depth.

A detector is placed so as to collect these repelled ions ; the image formed from all the collected ions can be of sufficient resolution to image individual atoms on the tip surface.

This is often not an ideal solution for GIF images, both because the loss of spatial resolution typically makes an image look fuzzy on the screen, and because the dithering patterns often interfere with the compressibility of the image data, working against GIF's main purpose.

Click the image for higher resolution to see details regarding the locations of important structures.

Information theory and digital signal processing offer a major improvement of resolution and image clarity over previous analog methods.

In the fall of 2006, researchers developed and installed an " autonomous observatory " using robotic video cameras with image processing software that detects and records high resolution video of birds in flight inside a high probability zone in the Cache River area.

In addition, jaggies often occur when a bit-mapped image is converted to a different resolution.

The Fisher-Price PXL-2000 camcorder of the late 1980s recorded a windowboxed image to compensate partially for low resolution.

* Razor sharp image with no bleeding / smearing when used at native resolution.

Displaying any other resolution either requires a video scaler, causing blurriness and jagged edges ; or running the display at native resolution using 1: 1 pixel mapping, causing the image either not to fill the screen ( letterboxed display ), or to run off the lower right edge of the screen.

A general kind of lossy compression is to lower the resolution of an image, as in image scaling, particularly decimation.

However, the technique suffers from low light intensity in final image of many biological samples, and continues to be affected by low apparent resolution.
