[Preston Dyches] What’s Up for July
0:04
The Moon gets the band back together,
0:06
find planet Uranus with some help from Mars,
0:09
and the star clusters that feel the Scorpion’s sting.
0:13
All month in July, as in June, the planetary action
Moon and planet pairings
0:17
is in the a.m. sky.
0:19
Find Saturn rising around midnight,
0:21
and climbing high into the south by sunrise.
0:24
Mars rises a couple of hours later, with Jupiter
0:27
trailing behind it, and shifting higher in the sky each day.
0:31
On July 2nd and 3rd before sunrise,
0:33
the crescent Moon will join Jupiter and Mars in the east.
0:37
Looking for them before the sky starts to brighten,
0:39
you’ll also find the Pleiades star cluster above Jupiter,
0:43
as well as bright stars Capella and Aldebaran.
0:46
As the Moon swings around the planet in its orbit,
0:49
this same group gets back together
0:51
at the end of the month,
0:53
but as a much tighter gathering of Jupiter, Mars, and the Moon
0:56
with the bright stars of the constellation Taurus.
1:00
Then on the evening of July 7th and 8th,
1:02
those with an unobstructed view of the western horizon can spot
1:05
Mercury shining brightly,
1:07
low in the sky with a slim crescent Moon.
1:10
Look for them starting 30 to 45 minutes after the Sun sets.
1:14
Observers in the Southern Hemisphere
1:16
will find Mercury a good bit higher
1:18
in the northwest sky all month after sunset.
1:21
On July 13, for the first few hours after dark,
1:24
look to the southwest to find the first quarter Moon
1:27
snuggled up with bright bluish-white star Spica.
1:31
For much of the lower 48 United States and most of Mexico,
1:34
the Moon will appear to pass
1:36
in front of Spica ? an event called an occultation.
Mars and Uranus
1:40
Next, over three days in mid-July,
1:43
grab your binoculars
1:44
and have a look at Mars in the early morning
1:46
before the sky starts to brighten, and you’ll find
1:49
the distant planet Uranus quite close by.
1:52
Uranus is not too difficult to see with binoculars
1:55
or a small telescope anytime it’s reasonably high
1:58
above the horizon at night, but you really need to know where
2:01
to look for it, or use an auto-guided telescope.
2:05
But occasionally the Moon or one of the brighter planets
2:08
will pass close to Uranus in the sky,
2:10
making for a great opportunity to find it with ease.
Star Clusters in Scorpius
2:15
The winding form of constellation Scorpius,
2:18
adorned with the bright red star Antares,
2:21
is a feature of the night sky
2:22
around the world this time of year.
2:24
And at the tip of the scorpion’s tail are two well-known
2:28
star clusters
2:29
that are well placed for viewing at this time of year.
2:32
M7, aka Ptolemy’s Cluster, and M6,
2:35
the Butterfly Cluster, are both located about 5 degrees
2:39
east of the bright stars
2:40
that mark the “stinger” end of the scorpion’s tail.
2:43
They reach their highest point in the sky
2:45
around 10 or 11 p.m. local time.
2:48
To find M7, imagine a line toward the east
2:51
through the “stinger stars,” Lesath and Shaula,
2:54
and it will lead you straight to the star cluster.
2:56
M6 is just a couple of degrees above M7.
3:00
Both are “open star clusters,” meaning they’re loose groupings
3:03
of stars that formed together, in the same region of space,
3:07
and they’re only loosely bound together by gravity,
3:09
so they’ll eventually go their separate ways.
3:12
M7 is just visible to the unaided eye
3:15
under dark skies
3:16
as a hazy patch just left of the tip of the scorpion’s tail.
3:20
But it’s best seen with binoculars
3:22
or a telescope with a wide field of view.
3:25
Its stars are located at a distance of about 1000
3:28
light years from us,
3:29
and they formed about 200 million years ago.
3:32
The cluster was discovered
3:33
by Greek-Roman astronomer Ptolemy in the year 130,
3:37
hence its other name.
3:38
M6 is about half
3:40
the apparent size of M7, and contains fewer stars.
3:44
It’s also a bit farther away from us,
3:46
at around 1600 light years.
3:48
It’s estimated to be about half as old
3:50
as M7, at an age of around 100 million years.
3:53
It was discovered by Italian astronomer and contemporary
3:56
of Galileo, Giovanni Battista Hodierna, in 1654.
4:02
These two clusters are easy to observe in July,
4:04
and their location in Scorpius makes them
4:06
pretty straightforward to locate on a clear night.
4:10
So there’s no reason to fear this scorpion’s sting.
4:13
Instead, let it guide you to two distant star clusters,
4:16
and see for yourself two little families of stars
4:20
in the process of spreading out into the Milky Way.
July Moon phases
4:24
Here are the phases of the Moon for July.
