Latest Chromosphere Stories
The strongest solar flare since NASA's Interface Region Imaging Spectrograph (IRIS) launched in the summer of 2013 was observed on January 28 of this year.
In June 2013, the solar observatory Sunrise was carried aloft by a NASA scientific balloon. Three months later, scientists from the Max Planck Institute for Solar System Research in Germany have presented unique insights into a layer on the sun called the chromosphere.
ESA scientists have recently discovered that neighbor star Alpha Centauri A displays some of the same bizarre temperature phenomena as our Sun and may help to solve a long-standing solar mystery.
It is actually the outer edge of the sun that you would find to be scorching, compared to the surface, and one study sought to find out why.
While the nation shoots off plenty of fireworks for the Fourth of July, NASA will be sending off its own rocket the next day.
New satellite imagery of the sun is providing scientists with clues to understanding the long-standing mystery of what is heating up the solar corona.
Sound waves escaping the sun's interior create fountains of hot gas that shape and power a thin region of the sun's atmosphere which appears as a ruby red "ring of fire" around the moon during a total solar eclipse.
Chromosphere -- The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 10,000 kilometers deep. The chromosphere is more visually transparent than the photosphere. The most common solar feature within the chromosphere are spicules, long thin fingers of luminous gas which appear like the blades of a huge field of fiery grass growing upwards from the photosphere below. Spicules rise to the top of the chromosphere and then sink...
Solar Flare -- A solar flare is a violent eruption that explodes from a star's photosphere with energies equivalent to tens of millions of hydrogen bombs. Solar flares from the Sun send out a streams of highly energetic solar wind that can present a radiation hazard to spacecraft outside of planetary magnetospheres and can disrupt radio signals on Earth. Solar flares were first observed on the Sun in 1859 by English astronomer Richard Carrington. They have also been observed to...
The Sun -- intensely hot, self-luminous body of gases at the center of the solar system. Its gravitational attraction maintains the planets, comets, and other bodies of the solar system in their orbits. The sun is actually a star of about medium size; it appears larger than the other stars because of its relative nearness to the earth. The earth's distance from the sun varies from 91,377,000 mi (147,053,000 km) at perihelion to 94,537,000 mi (152,138,000 km) at aphelion (see apsis). The...
