Evening Scene April 28, 2025
The evening scene shows the winter constellations
leaning over to the right as they tilt down into
the twilight. They are joined in 2025 by Jupiter
in eastern Taurus and Mars high above them Cancer.
For three evenings starting tonight, the crescent
Moon joins them to create a series of fascinating
alignments and conjunctions with background stars
and planets.
Jupiter is at magnitude -2.02 tonight, which makes
it brighter than Sirius by a considerable margin;
compare them by examining the image showing Sirius
and Orion versus the one showing Jupiter. Another
planet is part of the scene, although not visible
on any of the images; Uranus is located just above
the horizon, to the left of the Moon. Finally, we
have Mars situated in central Cancer, above any of
the views we show here.
As we can see, the Moon this evening is below the
Pleiades, and tomorrow we would see it about the
same distance above and to the left of the famous
cluster. Folks on the opposite side of the world
have the good luck of being able to see the still
slender crescent in the middle of the cluster. A
more immediate milestone for the Moon occurs in a
matter of a few hours, namely crossing from Aries
into Taurus.
The Moon's rendezvous with the Pleiades over the
next day is a manifestation of its orbital track
this year. Because its ascending node falls near
the vernal equinox, it travels even farther north
while on the northern half of the ecliptic. When
traveling on the southern half of the ecliptic it
exaggerates its southerliness because descending
node is near the autumnal equinox.
