I know, I know – I haven’t lived.

I came across the classic comedy sketch “Dinner for One” in YouTube over the weekend and laughed myself silly. So, if any of you have been hidden below ground for your whole life as I seemingly have, this will be quite a treat.

Carina Nebula

The wonderful image above was the Astronomy Picture of the Day on Google today. It’s a picture taken by the Hubble Space Telescope of the Carina Nebula, an emission nebula 7,500 light-years away.

After downloading the full image, I spent a few moments peering over the details when I found this:

Backatcha Hubble

Ah yes. Says it all really.

The media is reporting that a woman has been discovered in Cambodia who has lived in the wild since the age of eight. She is unable to speak any language and has had no normal human contact for 19 years.

I find the subject of feral children both fascinating and discomfiting. Feral children (children that have been brought up in the wild) have been documented for many centuries and have inspired many of the great works of children’s literature, from the Jungle Book to Tarzan.

These children have been the subject of much scientific research since the eighteenth century because these cases seemed to posess a key insight to deep questions about humanity. What are humans like when civilisation and socialisation are removed? What is our natural state? Are we influenced by nature or by nurture? What aspects of us are innate and what are acquired traits? Are we naturally good, or naturally bad? Can we change who we are? Is religion instinctive? How close are we really to our animal neighbours? In what specific ways are we different?

In the case of feral children, many of these questions remain unanswered. The feral state, for a human child, is an unnatural one. Many of the children were damaged by their experience and needed significant care for the rest of their lives. In fact, cases of modern day child-neglect (such as the Genie case) are not dissimilar. The cases seem to emphasise strongly that we humans need others and probably have always done so. Studying a lone child in the woods eating roots and berries tells us very little, apart perhaps how great our ability to survive is and what effect isolation can have on the development of a young mind.

A few years ago, I wrote up some of the more celebrated stories here, and a very compresensive account of all the stories can be seen at this site.

Update 2006/01/24 : Reportedly, the girl has tried to speak, but the words are not intelligible.

Apparently one of the brightest comets in 30 years is in the sky at the moment! You can see it just after sunset, so if the evening sky is clear, make your excuses and see if you can find it. It’s close to the sun, so look to the west. No binoculars or telescopes needed.

It’s beginning to cloud over here in preparation for yet another Atlantic storm, so I’m not sure if I’ll catch it myself. If you see it, let me know.

Here’s how to find it.

I saw a vivid fireball in the sky last night, and friends of mine are reporting the same – the Geminids are here, so be sure to pay attention to the skies over the next few days (if you are lucky enough to have clear skies). The meteor display should be greatest on Wednesday night and Thursday morning. You could possibly expect one every minute or so.

Wrap up warm, and good sightseeing!

An update: According to Spaceweather.com, a huge solar flare has erupted on the Sun, ejecting a lot of material “in our general direction”. So, not only might there be bright meteors tonight, but there is a small chance we might see auroras too. The Northern Lights are something that should not be missed. I saw them once here in Ireland, and it’s a memory I cherish – it was just magnificent. So, look for an eerie green glow in the sky tonight. You just never know..

I went to a very interesting lecture last night presented by Leo Enright, the Irish broadcaster and science journalist. He talked to us about the two NASA robot probes, Spirit and Opportunity, that are currently making their way across Mars. Spirit is currently holed up in the Columbia Hills in Gusev Crater, while Opportunity has come up to the edge of the impressive Victoria Crater on the Meridiani Planum.

They both landed there in January 2004, and were originally expected to work for around 3 months. Nearly 3 years later, they are still operational, sending back pictures almost every day. Spirit celebrates its 1,000’th “sol” on Mars today. To celebrate the occasion, a panoramic 360 degree view of the Columbia Hills has been released on the internet.

The view from the Victoria Crater is, if anything, even more stunning. The crater is about a kilometre wide, and in a few week’s time Opportunity will descend into it. (How it gets itself out is another question entirely).

Leo demoed a free application known as “Midnight Mars” that downloads the latest photos from the rovers onto your PC each night. Because the rover cameras are about the same height as an adult human, you get the distinct impression you are standing there yourself.

The probes have bolstered the case that Mars was once covered in water and they have provided an insight into the geology and stratigraphy of the planet. Looking at the photographs from Mars, I got the distinct feeling that we know very little about the place. There is a treasure trove of information waiting to be discovered by future robot probes, and maybe some time in the distant future, people themselves.

Update: My question about how Opportunity gets out of Victoria Crater has been answered: it doesn’t. It’s fate is being decided as we speak.
