Solar filters are used to safely observe and photograph the Sun, which despite being white, may appear as a yellow-orange disk. A telescope with these filters attached can directly and properly view details of solar features, especially sunspots and granulation on the surface , [ 4 ] as well as solar eclipses and transits of the inferior ...
A European spacecraft is showing us how dynamic the Sun is with newly released images, the highest-resolution images of our star's surface so far. Look (safely) at the Sun's surface in the highest ...
Celestial navigation by taking sights of the Sun and the horizon whilst on the surface of the Earth is commonly used, providing various methods of determining position, one of which is the popular and simple method called "noon sight navigation"—being a single observation of the exact altitude of the Sun and the exact time of that altitude ...
The Sun's rotation was thus shown to vary by latitude and that its outer layer must be fluid. In 1871 Hermann Vogel, and shortly thereafter by Charles Young confirmed this spectroscopically. Nils Dúner's spectroscopic observation in the 1880s showed a 30% difference between the Sun's faster equatorial regions and its slower polar regions. [29]
NASA's Parker Solar Probe is about to make its closest approach to the sun. The spacecraft will fly within 3.8 million miles of the solar surface. The spacecraft is collecting essential data that ...
The European Space Agency released four stunning images last week that show the sun in all its fiery glory. The images, obtained in March 2023 by the ESA's Solar Orbiter, represent what the agency ...
In the field of amateur astronomy there are many methods used to observe the Sun. Amateurs use everything from simple systems to project the Sun on a piece of white paper, light blocking filters, Herschel wedges which redirect 95% of the light and heat away from the eyepiece, [4] up to hydrogen-alpha filter systems and even home built ...
The Sun Gun Telescope, as featured in the August 1999 issue of Scientific American magazine, was designed so that large groups of people can view the sun safely - in particular it was created as a way to encourage children to become interested in astronomy.
