Comet ISON is now officially gone, well, pretty much. The NASA Comet ISON Observing Campaign has issued a memoriam for Comet ISON.
Here is the latest view:

ISON appears as a white smear heading up and away from the sun. ISON was not visible during its closest approach to the sun, so many scientists thought it had disintegrated, but images like this one from the ESA/NASA Solar and Heliospheric Observatory suggest that a small nucleus may be intact

EurtheCast (pronounced ‘earthcast’), a Vancouver company, has launched aboard a Russian Progress 53 cargo ship two cameras that will continuously photograph the surface of Earth 24/7 and relay pictures in near-real time back to earth.
One of the instruments is a still camera with a five-meter resolution and takes pictures of a 40km swath as the ISS circles the globe. The other instrument is a video camera with a one-meter resolution and will take 150 videos a day. These videos will be approximately 90 seconds long and have a 4k resolution.
With your free EurtheCast account, you can have a real time alert sent to you about locations on earth you want to watch as the UrtheCast cameras capture new imagery and video of your favorite places.
So, stand by for some great views of our planet from a place few people have been lucky enough to enjoy.
“On July 19, 2013, in an event celebrated the world over, NASA’s Cassini spacecraft slipped into Saturn’s shadow and turned to image the planet, seven of its moons, its inner rings — and, in the background, our home planet, Earth.”(NASA)
Remember when we wrote about the Casini Spacecraft photographing the Earth from the other side of Saturn? Well, now all the data and pixels have been put together with a lot of hard work from the project scientists and the amazing result is here:
Go look at the amazing image from across the solar system. You will be amazed…. Zoom in and look at the planets and other objects in the background.
Looking at the latest analysis of the data from the Kepler Spacecraft the number of habitable planets are potentially now one in five.
Analysis by UC Berkeley and University of Hawaii astronomers shows that one in five sun-like stars are potentially habitable.
“When you look up at the thousands of stars in the night sky, the nearest sun-like star with an Earth-size planet in its habitable zone is probably only 12 light years away and can be seen with the naked eye. That is amazing,” said UC Berkeley graduate student Erik Petigura, who led the analysis of the Kepler data.
When the James Webb Space Telescope is launched, hopefully in 2018, it should be able to look at these habitable plants and see in even more detail the surface of the planets. One of the four James Webb science themes is Planetary Systems and the Origins of Life.
It’s just a matter if time until we discover that first other ‘Blue Marble.’

ISON’s green glow may be due to the presence of carbon molecules and seems to be intact.

A new image of the sunward plunging Comet ISON suggests that the comet is intact despite some predictions that the fragile icy nucleus might disintegrate as the Sun warms it. The comet will pass closest to the Sun on November 28.
In this NASA Hubble Space Telescope image taken on October 9, the comet’s solid nucleus is unresolved because it is so small. If the nucleus broke apart then Hubble would have likely seen evidence for multiple fragments.
Moreover, the coma or head surrounding the comet’s nucleus is symmetric and smooth. This would probably not be the case if clusters of smaller fragments were flying along. What’s more, a polar jet of dust first seen in Hubble images taken in April is no longer visible and may have turned off.

Although the Draconid meteors appearance this year probably peaked last night you may get a look at them after sunset tonight. In the evening give your eyes a few minutes to adjust and look towards the constellation Draco just west of the North Star.
Also in the sky tonight is the International Space Station. Here is where and when to look:
Time: Tue Oct 08 7:27 PM cdt
Visible: 5 min
Max Height: 69 degrees
Appears: SW - Disappears: NE
With a clear sky tonight and a max height of 69 degrees the ISS will look like a jewel crossing the heavens. Enjoy.
Mars Express will take photos of Comet ISON’s coma, the atmosphere that surrounds ISON’s nucleus. Also, NASA’s Mars Reconnaissance Orbiter has been tracking ISON and may be able to get a look as well through October 2nd.
These cameras were designed to shoot high-resolution photos of Mars but scientists are going to attempt to use them to catch a glimpse of ISON as it passes. A lot depends on how bright ISON is as it gets closer to the sun. Keep your fingers crossed….
The high-resolution imaging science experiment (HiRISE) is one of six science
instruments for NASA’s Mars Reconnaissance Orbiter.

“This finding goes against what we thought, because we found that it’s one huge volcano,” said William Sager, a geology professor at the University of Houston in Texas. Sager is lead author in a study about the find that was published this week in the peer-reviewed journal Nature Geoscience.
“It is in the same league as Olympus Mons on Mars, which had been considered to be the largest volcano in the solar system,” Sager told National Geographic.
Comet ISON will come close to Mars on October 1, 2013 and NASA will attempt to photograph with the Mars orbiting MRO satellite’s telescope HiRISE. Then on Thanksgiving day comet ISON has its brush with the SUN.

Tonight, Wednesday August 28, the International Space Station, ISS, will cross the Baton Rouge sky at 7:58pm for about 4 minutes. If you have not ever seen the ISS move like a star across the sky it is well worth the effort. Look for a faint object towards the northwest about 36 degrees above the horizon moving towards you. It will move towards the southeast for about 4 minutes and the peak height in the sky will be 77 degrees which is almost over head. As it travels towards you it will get brighter and it will dim as it passes until it fades from sight in the southeast at about 11 degrees above the horizon.
Here is the link to find the ISS anywhere in the world. There is a link in this NASA site to sign up for email or sms text sent to let you know when the ISS will be over your location.
