In physics (especially astrophysics), redshift happens when
light or other electromagnetic radiation from an object moving
away from the observer is increased in wavelength, or shifted to
the red end of the spectrum. In general, whether or not the
radiation is within the visible spectrum, "redder" means an
increase in wavelength â equivalent to a lower frequency and a
lower photon energy, in accordance with, respectively, the wave
and quantum theories of light. Astronomers have used a novel
planet hunter instrument to detect a new possible life
supporting, Earth-like exoplanet. In fact the new planet is
classed as a super-Earth, since it has a minimum mass of 7.1
times that of our planet, and is properly located on its parent
star’s orbit to support the presence of liquid [...] The first
galaxies formed very fast after the Big Bang – in cosmic time,
that is. It’s estimated that the earliest ones appeared some 500
million years after the Big Bang, a period about which
researchers know very little. How they obs
