The Autumnal Equinox … FROM SPACE!

A few days ago—Sunday at 20:44 UTC (4:44 p.m. EDT), to be exact—was the moment of the autumnal equinox. There are a number of ways to explain this, though the definition is that it’s the moment the center of the Sun’s disk has a declination of zero degrees when it’s...

    Equinox Earth Image Credit: Roscosmos / NTSOMZ / Courtesy: Igor Tirsky,Vitaliy Egorov Explanation: From a geostationary orbit 36,000 kilometers above the equator,Russian meteorological satellite Elektro-L takes high-resolution images of our fair planet every 30 minutes. But only twice a year,during an Equinox,can it capture an image like this one,showing an entire hemisphere bathed in sunlight. At an Equinox, the Earth's axis of rotation is not tilted toward or away from the Sun,so the solar illumination can extend to both the planet's poles. Of course,this Elektro-L picture was recorded on September 22nd,at the northern hemisphere's autumnal equinox. For a moment on that date,the Sun was behind the geostationary satellite and a telltale glint of reflected sunlight is seen crossing the equator,at the location on the planet with satellite and sun directly overhead (5MB animated gif).

Summary of the top 5 'habitable planets'. Ps. Things are advancing so fast with recent discoveries with the Kepler Probe that we now already have an even stronger candidate than these five, Kepler-186f (see next pin on this Board), inside the Goldilocks Zone for the Red Dwarf Star it orbits & just 10% more massive than Earth. Place your bets please!

Very Pretty !!! Sheldon probably has this on his bedroom wall :)

Also known as the Moon's ashen glow, Earthshine is Earthlight illuminating the Moon's night side. Taken on Nowruz, the March 20 equinox, from Esfahan, Iran, this telescopic image captures strong Earthshine from an old Moon. The darker earthlit disk is in the arms of a bright sunlit crescent.
