Venus close to the Moon followup

Here's the followup picture from my previous post.

Venus and the Moon

We can use the Sun to help highlight the geography of the Moon, as the Sun slowly rises other the lunar surface light flood into vallerys and crators, or vast shadows are cast by mountain ranges. You can see this on the closeup below, the terminator isn't smooth, its all bumpy, even over the space of a few hours you can often see quite dramatic changes along the terminator as the Sun floods into areas of shadow.

Below you can see quite a prominant feature on the western rim of Mare Crisium, just as the Sun begins to rise over the highground around the sea.

Windows is the most secure operating system

According to Symantec it is. In their 11th internet security report, part of which tracked vulnerabilities and fix times for operating systems in the last half of 2006 they found the following:

Microsoft's Windows came in first place with 39 vulnerabilities discovered and Microsoft took on average 22 days to fix them.

Red Hat Linux came in second place with 208 vulnerabilities and an average fix time of 58 days.

Apple's Mac OS X ranked 3rd place with 43 vulnerabilities and an average fix time of 66 days.

Hewlett Packard's HP-UX had 98 vulnerabilities and took them 101 days to release a fix.

Sun's Solaris came in last place with 63 vulnerabilities with a fix time of 122 days.

Looks pretty much the same as the first half of the year. Microsoft's security investment is paying off. 2006 was a solid year for Microsoft on the security front. With how 2007 has started its going to get even better.

Venus close to the Moon

If you go outside right now (even if its daylight), Venus is a few degrees south of the Moon. That makes Venus possible to spot in daylight assuming you've got really transparent skies. You'll probably need binoculars but its possible.

It also means the Moon is hanging around near Venus in the evening sky, here's a photo I took yesterday.

Venus and the Moon

I've got high-resolution versions and close ups of the Moon on my gallery.

Weather permitting, I'll be taking one again this evening, the Moon would of moved up above Venus. This is because the Moon takes only a month or so to orbit the Earth, so every day it moves about 13° across the sky, the Moon is about half a degree in width which means it moves its own width about every hour compared to background objects. It orbits anti-clockwise when viewed from the north pole and so, compared to everything else in the sky it moves slowly leftward. Keep in mind the Earth's rotation is about 28 times faster, so we only see this movement relative to things behind it, the Moon still rises in the east and sets in the west.

Lunar eclipse

I managed to take a few images of the lunar eclipse last week, I only used my camera with the standard 55mm lens. I was feeling too weak to drag the telescope outside and set it up. :)

March 2007 Lunar eclipse

There's two more photos and the rest of my astrophotographs on my gallery.

Hamad Darwish's Windows Vista wallpapers released

Hamad Darwish has released the remaining images from his Windows Vista set. For those that don't know this is the guy who took the photos that made up two of the best wallpapers in Windows Vista.

Hamad Darwish's Windows Vista wallpaper

You can download the full size images (1900x1200) from his website. They compliment the existing wallpapers very nicely and I hope to see more of his photos in future versions of Windows.
