It created strong auroral displays that were reported globally and caused sparking and even fires in telegraph stations. [1] The geomagnetic storm was most likely the result of a coronal mass ejection (CME) from the Sun colliding with Earth's magnetosphere. [2] The geomagnetic storm was associated with a very bright solar flare on 1 September 1859.

Dungeness Spit is a sand spit jutting out approximately 5 miles (8 km) [1] from the northern edge of the Olympic Peninsula in northeastern Clallam County, Washington into the Strait of Juan de Fuca. It is the longest natural sand spit in the United States. [2] [3] The spit is growing in length by about 15 feet (4.6 m) per year.
The solar wind consists of particles (ionized atoms from the solar corona) and fields like the magnetic field that are produced from the Sun and stream out into space. Because the Sun rotates once approximately every 25 days, the heliospheric magnetic field [11] transported by the solar wind gets wrapped into a spiral.
Philolaus believed that universal harmony was achieved in the Central Fire, where the combination of an unlimited unit, fire, and the central limit formed the cosmos. [9] [10] It is presumed as such because fire is the "most precious" of elements, and the center is a place of honor. Therefore, there must be fire at the center of the cosmos. [6]
The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The reform advanced the date by 10 days: Thursday 4 October 1582 was followed by Friday 15 ...
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 ...
Vanguard 1. Expected to de-orbit in ~2240AD, this and its upper launch stage are the oldest human-made objects in space. Also the first use of solar cells to power a satellite.
