Emitted

The oceans are currently absorbing about a quarter of the carbon dioxide emitted to the atmosphere annually and are becoming more acidic as a result, leading to concerns about intensifying impacts on marine ecosystems.

Neutron stars spin rapidly giving off radio waves. If the radio waves appear to be emitted in pulses (due to the star's spin), these neutron stars are called pulsars.

The Cosmic Background Explorer (COBE)'s mission was to study the microwave sky in order to detect radiation emitted by the Big Bang.

Over the course of one solar cycle (one 11-year period), the Sun’s emitted energy varies on average at about 0.1 percent. That may not sound like a lot, but the Sun emits a large amount of energy – 1,361 watts per square meter. Even fluctuations at just a tenth of a percent can affect Earth.

Oceans are currently absorbing more than a quarter of the carbon dioxide emitted to the atmosphere annually by human activities, increasing their acidity.

The conspiracy minded claim photos the astronauts took on the moon do not show any stars in the background. In reality, the cameras were unable to capture the faint light emitted by stars.

Microdroplets emitted while sneezing and coughing can stay in the air for a long time.

The higher the temperature of an object, the faster its electrons vibrate and the shorter the peak wavelength of the emitted radiation.

Satellite instruments measure light emitted or reflected back to space at different wavelengths and create spectral reflectance curves.

The instrument, known as the Solar Wind Anisotropies, or SWAN, maps the constantly outflowing solar wind in interplanetary space by focusing on a wavelength of ultraviolet light emitted by hydrogen atoms.
