From there, his telescope-making career took off. To get around this, engineers started outfitting sub-orbital sounding rockets with detectors.
However, when Carruthers joined the fray, existing technology was bulky, fragile, and ill-suited to high-precision FUV astronomy. By the late s, Carruthers had solved the problem, inventing an FUV telescope that would go on to define the rest of his professional life. More sensitive and quantitative than analog imaging, the telescope captured FUV spectra by converting photons into energetic electrons.
These were then amplified and recorded by electron-sensitive film. Meanwhile, Carruthers had already started work on a far more ambitious application for his telescope design: as the first Moon-based observatory.
At the end of the mission, the astronauts removed the film from the device and returned it to Earth. Though a success in terms of operation, no one knew if the instrument had captured useful data. It would take an anxious two-week wait after the astronauts had splashed back down on Earth before Carruthers and his team could see the processed images for themselves.
They would not be disappointed. The camera had captured Earth in FUV light for the very first time, revealing the full extent of our atmosphere, the polar auroral zones, and the tropical airglow belt. And it had provided a survey of more than stars, nebulae, and galaxies that would have been impossible to see from the ground. For their part, Skylab astronauts managed to capture the hydrogen corona surrounding the comet, though Carruthers collected better data from a group of similar UV cameras flown aboard a sounding rocket over New Mexico around the same time.

George Washington Carver was an African American scientist and educator.
Carver is famous for many inventions including a number of uses for the peanut. Known as "Black Edison," Granville Woods was an African American inventor who made key contributions to the development of the telephone, streetcar and more. Frederick Jones was an inventor best known for the development of refrigeration equipment used to transport food and blood during World War II.
George Westinghouse is best known for inventing an air brake system that made railroads safer and promoting alternating current technology, which revolutionized the world's light and power industries. When he died in , he had 26 patents in his name. James West is a U. Charles Henry Turner, a zoologist and scholar, was the first person to discover that insects can hear and alter behavior based on previous experience.
Elijah McCoy was a 19th century African American inventor best known for inventing lubrication devices used to make train travel more efficient. Scientist George Carruthers created inventions, such as the ultraviolet camera, or spectrograph, which was used by NASA in the Apollo 16 flight, revealing the mysteries of space and the Earth's atmosphere.
Olivia Rodrigo —. Hubble UV spectroscopy of white dwarf stars has revealed that many of them are being continually bombarded by asteroids feeding the stars with rocky material. These observations allow us to learn the types of rocks present in extinct planetary systems which were perhaps once very similar to our own solar system. Hubble has continued its mission well beyond its original planned lifetime.
It has made over a million observations and generates about ten terabytes of new data each year. This leaves many astronomers keen to see a successor to Hubble that will continue its unique work in UV, which has added so much to human understanding by working beyond what we can see.
