![]() This study shows that the apparent magnitudes of the NIR counterparts look faint, just like optical counterparts ($<$18 mag). The significant improvement in sensitivity and resolution supplied by JWST will lead to a new perspective on the ambiguous nature of ULX donors, necessitating a significant reassessment of earlier infrared research into counterparts of ULXs. Thanks to the good enough resolution of the NIRCam images, most of the point-like and/or bright NIR counterparts of ULXs observed in past studies appear to be likely blended sources, so most likely, many of them do not have the enough of red color that an RSG could have. Possible scenarios for donor candidates of the two ULXs (ULX-5 and ULX-8) suggest that they could be either red supergiant (SRG) or red giant (RG) and also the counterpart of ULX-4 could be AGN or star cluster due to its high F200W ($-$12 mag). Through advanced astrometry based on the Chandra and James Webb Space Telescope (JWST) observations, as well as the GAIA optical source catalog, unique NIR counterparts determined for four ULXs while multiple potential NIR counterparts for remaining four ULXs within the astrometric error radius of 0.38 arcsec. It was launched on December 14, 2009.This work presents the properties of near-infrared (NIR) counterparts of eight ultraluminous X-ray sources (ULXs) in NGC 1672. NASA presently has solar-powered spacecraft in space with an infrared telescope called the Wide-field Infrared Survey Explorer (WISE). It revealed information about other galaxies, as well as information about the center of our galaxy the Milky Way. One of the most significant infrared telescope projects was the Infrared Astronomical Satellite (IRAS) that launched in 1983. Placing infrared telescopes in space completely eliminates the interference from the Earth's atmosphere. Together, United States scientists and the German Aerospace Center scientists placed a 17-ton infrared telescope on a Boeing 747 jet airplane. A more recent air-borne infrared telescope to reach the stratosphere was NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) in May 2010. Since then, aircraft like the Kuiper Airborne Observatory (KAO) have been adapted to carry infrared telescopes. These were the first air-borne infrared telescopes. In 1967, infrared telescopes were placed on rockets. With balloons, they were able to reach about 25 miles (40 kilometres) up. In the 1960s, scientists used balloons to lift infrared telescopes to higher altitudes. Ground-based infrared telescopes tend to be placed on high mountains and in very dry climates to improve visibility. Ground-based telescopes have limitations because water vapor in the Earth's atmosphere absorbs infrared radiation. Their popularity increased in the mid-1960s. Ground-based telescopes were the first to be used to observe outer space in infrared. They contain an infrared camera with a special solid-state infrared detector which must be cooled to cryogenic temperatures. Infrared telescopes may be ground-based, air-borne, or space telescopes. This invention, cooled by liquid helium, led the way for current infrared telescope development. In 1961, Frank Low invented the first germanium bolometer.Between 19, Harold Johnson created near-infrared photometers which allowed scientists to measure thousands of stars.These detectors were cooled with liquid nitrogen. In the 1950s, scientists used lead-sulfide detectors to detect the infrared radiation from space.Thomas Edison used an alternative technology, his tasimeter, to measure heat in the sun's corona during the solar eclipse of July 29, 1878.This was a very sensitive instrument that could electrically detect incredibly small changes in temperature in the infrared spectrum. In 1878, Samuel Pierpoint Langley created the first bolometer.In 1800, William Herschel discovered infrared radiation.There were several key developments that led to the invention of the infrared telescope: Some of these are gamma ray, x-ray, ultra-violet, regular visible light (optical), as well as infrared telescopes. In order to study the universe, scientists use several different types of telescopes to detect these different types of emitted radiation in the electromagnetic spectrum. Infrared light is one of several types of radiation present in the electromagnetic spectrum.Īll celestial objects with a temperature above absolute zero emit some form of electromagnetic radiation. SOFIA was an infrared telescope in an aircraft, allowing high altitude observationsĪn infrared telescope is a telescope that uses infrared light to detect celestial bodies.
