Resumen
La banda de ondas ultravioleta extrema (UVE), una vez considerada inutilizable para la astronomía debido a la opacidad del medio interestelar, ahora está revelando fuentes cósmicas distantes. La misión Extreme Ultraviolet Explorer ha explorado con éxito el cielo, ampliando nuestra comprensión del universo.
Área de la Ciencia:
- La astronomía es la astronomía.
- La astrofísica es la astrofísica.
- La exploración cósmica es la exploración cósmica.
Sus antecedentes:
- La banda de ondas ultravioleta extrema (EUV) (100-912 angstroms) fue históricamente considerada inaccesible para las observaciones astronómicas.
- Esta inaccesibilidad se atribuyó a la opacidad del medio interestelar, que absorbe la luz en estas longitudes de onda.
Objetivo del estudio:
- Investigar el potencial de la banda de ondas EUV para encuestas astronómicas.
- Para explorar el universo utilizando el espectro de EUV previamente pasado por alto.
Principales métodos:
- Utilizando datos del satélite Extreme Ultraviolet Explorer (EUE), lanzado en junio de 1992.
- Realizar un estudio del cielo dentro del rango de longitudes de onda de 100 a 912 angstroms.
Principales resultados:
- El medio interestelar exhibe una inhomogeneidad significativa en densidad e ionización, con el Sol situado en una región de baja opacidad.
- La misión EUE detectó una amplia gama de fuentes astronómicas, incluidos objetos extragalácticos, a distancias significativas.
- Los estudios en la banda EUV están contribuyendo activamente a una comprensión más profunda de la composición del universo.
Conclusiones:
- La banda de ondas del EUV es un espectro viable y valioso para la investigación astronómica.
- La misión EUE ha demostrado la efectividad de las encuestas EUV en el descubrimiento y estudio de objetos cósmicos.
- Los estudios en curso de EUV prometen avanzar significativamente en nuestro conocimiento del cosmos.

01:02Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for electronic transitions. As a result...
01:10Detection of Black Holes
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

01:14UV–Vis Spectrometers
The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell. Samples for...

The rate of heat transfer by emitted radiation is described by the Stefan-Boltzmann law of radiation:
01:26Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation
Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used.

01:28Field Application of Global Positioning System
The Global Positioning System (GPS) has become an indispensable tool in fieldwork, offering unparalleled precision and efficiency for surveying, navigation, and infrastructure development. By harnessing signals from a constellation of satellites, GPS receivers determine the location of objects with remarkable speed and accuracy, often completing calculations within a second.Advantages of Modern GPS TechnologyContemporary GPS receivers are designed to meet the practical demands of field...
