FOR LATE SPRING
* 2016 *
MERCURY transits across the face of the
Sun for the first time in 10 years on May
9, starting at 7:13 a.m. EDT and lasting
until 2:41 p.m. EDT.
MARS shines its brightest for the entire
year, appearing as a reddish-orange
“star” with magnitude -2.0 in the
south-eastern evening sky, and reaches
its closest point to the Earth since 2005
on May 30.
JUPITER appears high in the southwestern evening sky, outshining all stars
with a magnitude of -2.3
SATURN reaches opposition on June 3,
rising at sunset shortly after Mars and
shining its brightest for the year with a
magnitude of 0.
The star groups linked by lines are the
constellations created by our ancestors
thousands of years ago as a way of
mapping the night sky. Modern
astronomers still use the traditional
names, which give today’s stargazers a
permanent link to the sky myths and legends of the past. This season's
evening sky features the Big Dipper. Its seven stars are bright enough
to be visible through the glow of a city sky. Not a true constellation, the
Big Dipper forms pattern of stars found within the constellation known
as Ursa Major, or the Great Bear.

SPACE STATION SIGHTINGS
As the space station orbits the Earth, sunlight reflects off of its giant solar arrays.
From Earth, it appears as a bright object moving high across the night sky. Visit

ROTATING NIGHT SKY: During the night, the Earth’s rotation on its axis slowly
shifts the entire sky. This is the same motion that swings the Sun on its daily eastto-west trek. The rotational hub is Polaris, the North Star, located almost exactly
above the Earth’s North Pole. Everything majestically marches counter-clockwise
around it, a motion that becomes evident after about half an hour.

TO USE THIS CHART: Hold the chart in front of you and rotate it so the direction
you are facing (N,S,E,W) is at the bottom of the chart. The edge of the chart
represents the horizon; the overhead point is at centre. On a moonless night in the
country, you will see more stars than are shown here; deep in the city, you will see
fewer. The ecliptic line is the celestial pathway of the Moon and planets. The star
groups straddling this line are known as the zodiac constellations. The Moon is
shown for selected dates.
