The Pithy Amateur Astronomer

The adventure and aggregation of a short-winded amateur astronomer.

Saturn's moon Mimas has received recognition in the past as being a resemblance to the Star Wars Death Star. This is caused by a shape that an impact crater caused on its surface. 

It seems not only does this moon resemble something from a long time ago in a galaxy far away, but also munches on small pixels. 

With April 1st coming in a few days, I do have my speculations.

Obviously, our planet is not the only one to experience different seasons. MSNBC has put together a small slideshow of "springtime in space".

And that's all I am going to say about that.

Ahh! The better to make you confused and dazed, my dear.

I always thought it was humorous how dark energy is being studied but (to my knowledge, which is little) how much we don't know about it.

When I was in 4th grade, my teacher said we know more about space than we do the ocean. While that was true, I've come to believe that we know equally as less about one as we do the other.

I made a post a few weeks ago about "Bigfoot on Mars" and how I personally see it as a Tuscan Raider from Star Wars. Well, sticking to that same silly thought pattern, this can be called Jabba the Hutt.

Sorry for not updating. I've been real busy.

Today's Astronomy Picture of the Day is of the Sun (Sol) and a feature called a prominence.

Explanation: Dramatic prominences can sometimes be seen looming just beyond the edge of the sun. Such was the case last week as a giant prominence, visible above on the right, highlighted a Sun showing increased activity as it comes off an unusually quiet Solar Minimum. A changing carpet of hot gas is visible in the chromosphere of the Sun in the above image taken in a very specific color of light emitted by hydrogen. A solar prominence is a cloud of solar gas held just above the surface by the Sun's magnetic field. The Earth would easily fit below the prominence on the right. Although very hot, prominences typically appear dark when viewed against the Sun, since they are slightly cooler than the surface. A quiescent prominence typically lasts about a month, and may erupt in a Coronal Mass Ejection (CME) expelling hot gas into the Solar System. The next day, the same prominence looked slightly different.

http://csep10.phys.utk.edu/astr161/lect/solarsys/scale.html has a nice image on how the other planets look in comparison to the Sun.

I just downloaded the new Firefox update (3.6) and learned that there are personas. Personas are basically themes but seem to be a bit more personal (Wow...That sounded a bit redundant, didn't it?). I went and searched for some space personas and though I would share the ones I really like.

The one I am using now is the Hubble NGC http://www.getpersonas.com/en-US/persona/74585

The second favorite one of mine is http://www.getpersonas.com/en-US/persona/116

Both of these are irrelevant unless you just like to customize your browser. I have to say my personal favorite is the Hubble NGC (it is of NGC 2818 http://en.wikipedia.org/wiki/NGC_2818 for reference because I don't think the persona has the details listed).

I have no idea what galaxy is in persona 116 but if I figure it out I will let you know (or you can always post your best guess).

I tried to photograph Saturn again tonight. I had it perfectly aligned on the telescope and it was a clear night. The view was so clear, I could even see a moon (that I haven't identified yet).

However...the images are horrible. I have yet to purchase a proper camera mount. If I had the mount and aligned Saturn to show up in the center like I did tonight, a simple 30-90 second video would yield great quality. But alas, things in life aren't free.

Here are my pictures that I had to heavily doctor up just so you could see SOMETHING that looked like rings even though they are a blur in the photograph. Trust me though, it is cooler to see in better quality.



 

Bleh...

This picture was taken a few years ago but it is still humorous. Apparently, bigfoot has been sighted on Mars. I know that it's not bigfoot because he's too busy getting back at people eating Jack Link's Beef Jerky.

According to Fox News (I lost the citation, sorry):

The "alien" is actually a blurry detail in a huge panoramic photograph snapped on the edge of Mars' Gusev crater by NASA's Spirit rover in early November, and posted on NASA's Web site on Jan. 2.

I would like to think that it was a Tuscan Raider...but that's me.


Today's Astronomy Picture of the Day is rather bizarre. It looks like someone is dragging a can of paint around or someone didn't make sure their kids didn't have access to their parents sharpies. 

This is similar to one of the pictures that was a deciding factor for me to start blogging about my amateur astronomy endeavors. I will paste both images and the information below.


Explanation: What creates these picturesque dark streaks on Mars? No one knows for sure. A leading hypothesis is that streaks like these are caused by fine grained sand sliding down the banks of troughs and craters. Pictured above, dark sand appears to have flowed hundreds of meters down the slopes of Acheron Fossae. The sand appears to flow like a liquid around boulders, and, for some reason, lightens significantly over time. This sand flow process is one of several which can rapidly change the surface of Mars, with other processes including dust devils, dust storms, and the freezing and melting of areas of ice. The above image was taken by the HiRise camera on board the Mars Reconnaissance Orbiter which has been orbiting Mars since 2006. Acheron Fossae is a 700 kilometer long trough in the Diacria quadrangle of Mars.

Here shortly, Venus will be back in the evening sky. For a while, the monster Jupiter was in the evening sky (of course, so was Saturn in my back yard, But alas, I do not have the money for a camera mount just yet so you all will have to make do with other pictures).

This article discusses all the details of how to spot Venus and when one can find other Planets in the evening.
