Astronomical Society of the Pacific
The Astronomical Society of the Pacific (ASP) is an American scientific and educational organization, founded in San Francisco on February 7, 1889.

Atmosphere
An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.
New!!: Chromosphere and Atmosphere · See more »
Convection
Convection is the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock (rheid).
New!!: Chromosphere and Convection · See more »
Corona
A corona (Latin, 'crown') is an aura of plasma that surrounds the Sun and other stars.

Coronal mass ejection
A coronal mass ejection (CME) is a significant release of plasma and magnetic field from the solar corona.

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life.
New!!: Chromosphere and Earth · See more »
Eclipse
An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer.
New!!: Chromosphere and Eclipse · See more »
Electron
The electron is a subatomic particle, symbol or, whose electric charge is negative one elementary charge.
New!!: Chromosphere and Electron · See more »
Energy level
A quantum mechanical system or particle that is bound—that is, confined spatially—can only take on certain discrete values of energy.
New!!: Chromosphere and Energy level · See more »
Granule (solar physics)
Granules on the photosphere of the Sun are caused by convection currents (thermal columns, Bénard cells) of plasma within the Sun's convective zone.

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen.
New!!: Chromosphere and Hydrogen atom · See more »
Magnetic reconnection
Magnetic reconnection is a physical process in highly conducting plasmas in which the magnetic topology is rearranged and magnetic energy is converted to kinetic energy, thermal energy, and particle acceleration.

Moreton wave
A Moreton wave or Moreton-Ramsey wave is the chromospheric signature of a large-scale solar coronal shock wave.

Photosphere
The photosphere is a star's outer shell from which light is radiated.

Plage (astronomy)
A plage is a bright region in the chromosphere of the Sun, typically found in regions of the chromosphere near sunspots.
New!!: Chromosphere and Plage (astronomy) · See more »
Poaceae
Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses, commonly referred to collectively as grass.

Skylab
Skylab was the United States' space station that orbited the Earth from 1973 to 1979, when it fell back to Earth amid huge worldwide media attention.

Solar and Heliospheric Observatory
The Solar and Heliospheric Observatory (SOHO) is a spacecraft built by a European industrial consortium led by Matra Marconi Space (now Astrium) that was launched on a Lockheed Martin Atlas II AS launch vehicle on December 2, 1995, to study the Sun, and has discovered over 3000 comets.

Solar flare
A solar flare is a sudden flash of increased Sun's brightness, usually observed near its surface.
New!!: Chromosphere and Solar flare · See more »
Solar prominence
A prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape.
New!!: Chromosphere and Solar prominence · See more »
Solar transition region
The solar transition region is a region of the Sun's atmosphere, between the chromosphere and corona.
New!!: Chromosphere and Solar transition region · See more »
Space weather
Space weather is a branch of space physics and aeronomy concerned with the time varying conditions within the Solar System, including the solar wind, emphasizing the space surrounding the Earth, including conditions in the magnetosphere, ionosphere, thermosphere, and exosphere.
New!!: Chromosphere and Space weather · See more »
Spectral line
A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies.
New!!: Chromosphere and Spectral line · See more »
Spectrum
A spectrum (plural spectra or spectrums) is a condition that is not limited to a specific set of values but can vary, without steps, across a continuum.
New!!: Chromosphere and Spectrum · See more »
Spicule (solar physics)
In solar physics, a spicule is a dynamic jet of about 500 km diameter in the chromosphere of the Sun.

Temperature
Temperature is a physical quantity expressing hot and cold.
New!!: Chromosphere and Temperature · See more »
TRACE
Transition Region and Coronal Explorer (TRACE) was a NASA heliophysics and solar observatory designed to investigate the connections between fine-scale magnetic fields and the associated plasma structures on the Sun by providing high resolution images and observation of the solar photosphere, the transition region, and the corona.
