Carpe Noctem - Seize the Night!

Planets

    Evening Planets
  • Saturn - 0.1 mag In Cancer and on the western horizon just after sunset and favored for those of you in the Southern Hemisphere. Up north I haven't been able to see Saturn in the glare of sunset (and clouds) for a while. If you feel like you are missing Saturn because of these long Northern Hemisphere days head on over to the Cassini Imagine website and get yourself a little Saturn fix! For those of you in the Southern Hemisphere there it gets dark super early so you have a few more hours with Saturn that we do.
  • Mars - Mag +1.6 and has moved in to Leo the Lion and this weekend is sitting close enough to Regulus to make it look like a very unique double star system. You will have to look hard in the haze of the horizon.
  • Jupiter - Mag -2.5 in Libra. Clearly visible high in the sky just after sunset, 15 degrees east of Spica. Any telescope can reveal its two widest cloud bands and four Galilean satellites.
    Listener Kevin recommended a piece of free software that I now have on all my computers Jupiter 2 (Thanks Kevin!).
  • Uranus - Mag. 5.9 in Aquarius draw a line between Fomalhaut and Markab (opposite corner of the square of Pegasus from Andromeda) and Uranus is close to the middle.
  • Neptune - Mag. 7.9 in Capricorn half way between Fomalhaut and Theta Aquilli the eastern wing-tip of Aquila the Eagle.
  • Pluto Mag. 14 in Serpens Cauda

    Morning Planets

  • Venus - Mag -3.9 The brightest morning planet visible. Low in the eastern morning sky. This weekend she moves near Zeta Tauri and makes a nice triangle with M1 the Crab Nebula and Zeta. She will continue to move towards Cancer and closer to the sun during the week.

Carpe Noctem - Seize the Night!

Murphy's Law (addendum)
If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong.

Special thanks to Ron for sticking up for me in the posts, Tom of Tom's Astronomy Blog for keeping an eye on me, Jim (RapidEye) for some great moral support and Tom and Woodland Hills for his support and patience.

Thanks to all of you for waiting so patiently and for your understanding with all of the mess-ups this month.

Listener Feedback

Ron sent an email sharing some information on a new, free, design for a trackball style dobsonian/equatorial hybrid that will be in the August Sky and Telescope magazine.

He also passed along a little trick for using a go-to scope as a teaching aid. He attached a green laser pointer to a go-to scope and had it slew to different objects so that new dobsonian drivers could follow and see where he was pointed to find the objects them selves.

I find this also works well with binoculars! Strap the green laser to your binos and then when you find an object just turn on the laser so those looking in the sky with binos next to you can follow your beam. Much easier then holding the laser pointer with one hand and the binos with the other.

Our friend James from NZ writes:
"Hi Alice,
I hope the house panting has been progressing well !!!
Well it stopped snowing !!!!!!!! here, today we have a tropical 2 degrees with sleet and heavy rain.
I was asked a question over the weekend that I had to Google the answer for - it was, what is a "blue moon". Good question I thought. You might like to mention / expand on it in a podcast - this I got from wikipedia.

All the best
James "

Blue Moons from Wikipedia

"What is a Blue Moon?" from Sky and Telescope

Listener Question

Michael want to know where he could find images of the "face" on Mars. There are some good comparison pictures of the Viking and MGS images on the Mars Global Surveyor website. There are also some amazing Mars images on the PanCam site
and if you want to see something special look at the animated gif file of Earth rising as imaged by rover Opportunity. Is that creepy enough for you Michael?

Constellations

Antlia (ANT-lee-uh) - the air pump. The French astronomer Abbé Nicolas Louis de Lacaille created 13 constellations for the southern sky to fill some star poor regions, among them Antlia

Sagitta - the arrow is the third smallest constellation. Other interpretations considered the arrow to have been shot by Centaurus at Aquila but with Sagittarius just to the west it could very well come from that famous archer too.

Delphinus (del-FY-ness)- the Dolphin. According to the first one, Greek god Poseidon wanted to marry Amphitrite, a nereid. She, however, wanting to protect her virginity, fled to the Atlas mountains. Her suitor then sent out several searchers, among them a certain Delphinus. Delphinus accidentally stumbled upon her and was able to persuade Amphitrite to accept Poseidon's wooing. Out of gratitude the god placed the image of a dolphin among the stars.

Notables: Gamma marks one corner of the asterism Job's Coffin. It is one of the best known double stars in the sky. The system consists of a 4th magnitude orange subgiant and a 5th magnitude yellow-white main sequence star.
Alpha Delphinus It also has the name Sualocin, which was given to it as a practical joke by the astronomer Niccolò Cacciatore; the name is the Latinized version (Nicolaus) of his given name, spelled backwards

Equuleus (eh-KWOO-lee-us)- the Colt or Foal is the smallest northern hemisphere constellation and the 2nd smallest constellation after Crux in the S.H. Equuleus is associated with the foal Celaris, who was the brother of the winged horse Pegasus. Celaris was given to Castor by Mercury.

Viewing

Naked eye - After finding the Coat hanger in the binoculars in the last show can you find them now with out optical aids? You will not see its distinctive shape but should still see the fuzziness of the cluster.

Step outside just after sun set and find Jupiter. Now as the stars start to appear see if you can identify the brightest stars without the rest of their constellation. If you were navigating on the ocean without technology it would be important.

Binocular -
In the high northern latitudes it is 11pm or later before it gets dark enough for deep sky binocular work so you can warm up with planets and Re-visit Coma Berenices before it starts getting any lower and then head over to Lyra and catch the first part of the Double-Double

Also swing over to Delta Cygnus and look for a large ring of stars circling that 4th brightest star. Head over to Ophiucus and star gobbling up globulars!

Telescope -
We talked about the Coat hanger asterism on our last show but for telescopes the entire asterism is too large. BUT there is a lovely double star to check out that is just right for scopes. the bright star in the bend of the Coat hanger 'hook' is Struve 2521 a quad star system.

Review - With a dark weekend go back and take a look at Leo, Virgo and Coma Berenices before they disappear!


Also, go and visit the Dumbbell Nebula (M27) near our little Sagitta, to me it looks very much like an apple core. Sliding due south of the Dumbbell is a very nice globular cluster M71. It sits right between the two bright stars that make up the shaft of Sagitta.



The Moon

Last Quarter - July 17
New Moon - July 24th

Now if you download this after the full moon step out and try to pick up these objects as the terminator passes from east to west across the meridian.
Object Latitude Longitude Comments
Mons Pico 45.7 -8.9 Spanish for "peak"
Mons Piton 40.6 -1.1 Named from Mt. Piton on Tenerife Islands
Crater Archimedes 29.7 -4 Greek physicist, mathematician (c. 287-212 B.C.)
Crater Timocharis 26.7 -13.1 Greek astronomer (unkn-fl. c. 280 B.C.)
In approximately 3rd century BC, with the help of Aristillus, he created the first star catalogue in the Western world. (His worked was predated by that of the Chinese astronomer Gan De.) Over 150 years later, Hipparchus would compare his own star catalogue to Timocharis' and discover that the longitude of the stars had changed over time, which led him to determine the first value of the precession of the equinoxes.
Crater Bullialdus -20.7 -22.2 Boulliau, Ismael; French astronomer (1605-1694)
In 1640, he suggested that the force of gravity follows an inverse-square law. (Isaac Newton made this idea precise in his 1687 work, the Principia)
NASA engineers capture a meteoroid impact on the moon.

Remember latitudes that are negative (-) are South and longitudes that are negative (-) are West!

News

Pluto's two new moons get names. - (from AAAS, read on...)

In mythology, Pluto ruled the underworld. Nyx was the goddess of night and the mother of Charon, the boatsman who takes souls across the River Styx and into Pluto's grasp. Pluto's large satellite, discovered in 1978, is called Charon. Because an asteroid with the name Nyx already exists, the IAU decided to use a slightly different spelling for the inner one of the two small Plutonian moons, to avoid confusion. Hydra was the mythological nine-headed serpent that guarded the underworld. A large but inconspicuous constellation in the spring sky also bears this name.

The first letters, N and H, also refer to NASA's New Horizons spacecraft, which was launched in January and is now on its way to an encounter with the Pluto system in the summer of 2015

Hubble's ACS camera fails - (from AAAS, read on...) but not before giving us the best photo yet of Pluto, Charon, Nix-msp and Hydra.

Chandra shows magnetic fields around black hole - (from Chandra site, read on...)

ESA's SMART-1 spacecraft return images of the highly eroded 'far side' of the moon. (from ESA, read on...)

Comets for July.

This month we have comets for everyone except those above 55 degrees north.

I am trying!  I really am!  ;-)

Just when I thought that I was finally past the technical problems it looks like Libsyn has gone wacko...

So after I loaded the podcast instead of getting Astronomy a Go! Go! I was getting someone else's podcast or dancing bunnies.  Humm. 

So with that I will let you all know when it is safe to listen again!!  Since some of my listeners have younger kids with them I would rather not have a random podcast pop up!

Here is what Libsyn has to say....

"
System Error Discovered
This morning, betweeen the hours of approximately 12:45am eastern to 1:45, Libsyn servers experienced a crucial distribution error on its CDN that resulted in the erroneous distribution of files on some user accounts.  The problem has been identified and resolved, however during the time of the error period, affected user accounts may have had the wrong files distributed to subscriptions and direct downloads that called for files.

We are extremely sorry for the confusion and surprise that this may cause the subset of audiences that have been affected by this unusual error.   While this was a temporary and limited issue, it may have real unintended  consequences to some individuals; we fully understand the magnitude of delivering the wrong file, even one mis-matched file is one too many. "

All of the observations are for 10-11pm for the mid latitudes as you move south it gets darker sooner so if you go out before 10 rotate my observations to the east 15 degrees for each hour. For the S. Hemisphere observations observations will be ~8pm

28-29 Southern Delta Aquarids Meteor Shower. The Delta Aquarids usually produce about 20 meteors per hour at their peak. The radiant point for this shower will be in the constellation of Aquarius. Best viewing is usually to the east after midnight

Beginning of the month

Planets

Mercury is slipping away and by the middle of the month will be lost in the glare of the Sun
Saturn and Mars, which at the middle of June were snuggled up next to each other in the same field of view, are now getting further apart. Saturn is slipping below the horizon just after sunset and if you have keen eyes you can still catch Saturn and his rings before sunset.
Mars is speeding along the ecliptic but he is still no match for how the earth's path around the sun is changing our perspective. At the beginning of the month, Mars sits low on the western horizon. For those of you in the S.Hemisphere your early evenings give you a little bit more time with both Saturn and Mars so make sure you get out side and spend some time with that pair setting in the west.

For N or S nothing beats Jupiter this month. Jupiter seems to hover between Libra and Virgo for the beginning of the month as Jupiter reverses its retrograd path and returns to proper eastward motion. No matter if you are in the North riding along the equator or in the S.Hemisphere just look for the brightest object along the ecliptic after sunset. Even before dark an 8" telescope can pick up the 4 Galilean moons around Jupiter and binoculars can pick them up once it gets good and dark.
Venus starts out the month between the horns of Taurus the bull who we just said good by to as a winter constellation just a couple of months ago. Venus is slowly making her way back towards the sun so watch for her in the early mornings before sunrise

Constellations

  • Leo
  • Virgo
  • Hydra
  • Ophiuchus
  • Scorpius

End of the month

Have you noticed how the amount of sunlight has changed as we go into August? August 1st is the cross quarter day between our last solstice and our next equinox!

Planets

Mercury is in the morning sky, low on the horizon. It will be a couple of weeks to get high enough to be seen
Saturn has slipped below the horizon and is lost in the glare of the sun. Southern hemisphere has a slight advantage.
Mars is low on the western horizon and in between the feet of Leo the Lion

Jupiter is between Libra and Virgo for
Venus by the end of the month sits between the Gemini twins
