There is always Earthshine
on the moon, but it can be viewed by the naked eye only when the crescent moon is very slim.
issue was never explored and Wilkinson's concerns remain unanswered by the FIRAS team to this day.
A classic set featuring a song for every year, including 2112, Spirit of Radio, Tom Sawyer, YYZ and from the latest album Earthshine
, had a full house baying for more.
For example, Herschel's "volcanic eruptions" occurred when earthshine
flooded Aristarchus--a very bright crater whose visibility varies according to seeing and illumination conditions.
On the nights of January 23 and 24, the Moon will show a crescent phase and you may be able to see Earthshine
- where light reflecting from the - Earth illuminates what would otherwise be the "dark side" of The Moon.
The star tracker cameras took the images during lunar day with Earthshine
lighting up the moon's surface, NASA officials said.
Section members have also contributed work to the BAA Journal during the session under review, including a note on earthshine
by Nigel Longshaw (JBAA 120:4), a short paper on lunar cusp phenomena by Richard Baum (120:6), and a report on the total eclipse of 2010 Dec 21 by the Director (121:1).
Scientists studying Earthshine
- Earthlight reflected off the Moon - found clear signs of water and an oxygen atmosphere, as well as suggestions of plant life.
The dark part of the Moon in the syzygies" refers to Earthshine
inside the crescent near the time of new Moon.
As the sky darkens, many people will see the dark, left-hand portion of the lunar disk filled in with a ghostly glow known as earthshine
That's when you can see both the sunlit sliver and the entire rest of the disk lit up by earthshine
(see page 9).
Detection of such a delicate phenomenon, he realised, would critically depend on the strength of earthshine
and the brightness of the sky; and of course, the phase and altitude of the Moon, a suite of circumstances not often encountered.
