Raw images from Cassini were received on Earth shortly after the event, and a couple of processed images—a high-resolution image of the Earth and the Moon, and a small portion of the final wide-angle mosaic showing the Earth—were released to the public a few days following the July 19 imaging sequence.
The stellar classification of HD 206893 is F5V, [3] matching an F-type main-sequence star that is generating energy through hydrogen fusion at its core.Its metallicity – the abundance of elements more massive than helium – is similar to that in the Sun. [7] Due to uncertainties in the age of young F-type dwarfs, the age of the star is not well constrained but is most probably in the range ...
First image, color images and movie of Earth from space taken by a person, by cosmonaut Gherman Titov – the first photographer from space. [25] [26] 1963 KH-7 Gambit: First high-resolution (sub-meter spatial resolution) satellite photography (classified). [27] 1964 Quill: First radar images of Earth from space, using a synthetic aperture ...
An artist's conception of HD 189733 b following the 2013 confirmation of the planet's blue color by the Hubble Space Telescope. The appearance of HD 189733 b beyond the blue color is unknown. In 2007, the Spitzer Space Telescope was used to map the planet's temperature emissions. The planet and star system was observed for 33 consecutive hours ...
Space observatories opened a "new sky" for astronomers. However, there is a challenge involved in the design of infrared telescopes: they need to stay extremely cold, and the longer the wavelength of infrared, the colder they need to be. If not, the background heat of the device itself overwhelms the detectors, making it effectively blind.
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of over 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.

HD 209458 b is an exoplanet that orbits the solar analog HD 209458 in the constellation Pegasus, some 157 light-years (48 parsecs) from the Solar System. The radius of the planet's orbit is 0.047 AU (7.0 million km ; 4.4 million mi ), or one-eighth the radius of Mercury 's orbit (0.39 AU (36 million mi ; 58 million km )).
