An aurora [a] (pl. aurorae or auroras), [b] also commonly known as the northern lights (aurora borealis) or southern lights (aurora australis), [c] is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains ...
Scientists said the sun is now in its solar maximum, or the peak of its 11-year solar cycle.
After two solar cycles, the Sun's magnetic field returns to its original state, completing what is known as a Hale cycle. This cycle has been observed for centuries by changes in the Sun's appearance and by terrestrial phenomena such as aurora but was not clearly identified until 1843.
The sun is growing more active than scientists predicted. About every 11 years, the sun's magnetic fields flip, increasing solar activity. That activity can disrupt radio communications and GPS ...
An aurora is a natural light display in the sky, especially in the high latitude (Arctic and Antarctic) regions, in the form of a large circle around the pole. It is caused by the collision of solar wind and charged magnetospheric particles with the high altitude atmosphere ( thermosphere ).
The weekend will kick off with a rare celestial show as the northern lights illuminate the night sky over the northern United States. Over the past few days, the sun has launched massive clouds of ...
The Sun is 1.4 million kilometers (4.643 light-seconds) wide, about 109 times wider than Earth, or four times the Lunar distance, and contains 99.86% of all Solar System mass. The Sun is a G-type main-sequence star that makes up about 99.86% of the mass of the Solar System. [26]
According to NOAA, the best time to see aurora borealis is between 10 p.m. and 2 a.m. local time. NORTHERN LIGHTS FORECAST From University of Alaska, highly active aurora displays will be visible ...
