The enormous crater Herschel on Saturn's moon Mimas; The Herschel gap in Saturn's rings. 2000 Herschel, an asteroid; The William Herschel Telescope on La Palma; The Herschel Space Observatory, successfully launched by the European Space Agency on 14 May 2009. It was the largest space telescope of its kind, until the launch of the James Webb ...
He discovered Saturn's biggest moon, Titan, and was the first to explain Saturn's strange appearance as due to "a thin, flat ring, nowhere touching, and inclined to the ecliptic." [10] In 1662, he developed what is now called the Huygenian eyepiece, a telescope with two lenses to diminish the amount of dispersion. [11]
Henrietta Swan Leavitt (/ ˈ l ɛ v ɪ t /; July 4, 1868 – December 12, 1921) was an American astronomer. [2] [1] [3] Her discovery of how to effectively measure vast distances to remote galaxies led to a shift in the scale and understanding of the scale and the nature of the universe. [4]
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
In addition he discovered the Cassini Division in the rings of Saturn (1675). [7] He shares credit with Robert Hooke for the discovery of the Great Red Spot on Jupiter (ca. 1665). Around 1690, Cassini was the first to observe differential rotation within Jupiter's atmosphere .
Scientists have discovered a mysterious pulsating light—and they don’t know what it could be. It pulses at a rate of about once every 21 minutes, and has been doing so since at least 1988.
A study published in the journal Science suggests a hypothetical moon (called Chrysalis) came too close to Saturn's gravitational pull and was torn apart, forming the planet's iconic rings.
Christiaan Huygens followed on from Galileo's discoveries by discovering Saturn's moon Titan and the shape of the rings of Saturn. [14] Giovanni Domenico Cassini later discovered four more moons of Saturn and the Cassini division in Saturn's rings. [15] The Sun photographed through a telescope with special solar filter.
