Nothing’s more complicated than choosing a new telescope these days, and that’s because there are just too many choices to consider. On the one hand, not all are made the same and so they’re not suited for the same purpose. On the other, there are price differences to consider, constructional quality details, as well as convenience and ease of use, and they all need to be mulled over before making a final call.

 

There are three main types of telescopes you ought to make up your mind on. Refracting telescopes are more affordable than their counterparts and that’s because they are more prone to color aberrations and others. The quality of the image is somewhat lower compared to that which can be ensured by a reflecting telescope. Both the material that the latter has been made out of is better, but it’s also beneficial for a number of other reasons. For example, reflectors are large, which means that they can collect much more light and make it possible for you to glance at a brighter and clearer image.

Cassegrain telescopes are others you ought to take into account. They combine the advantages of reflectors and refractors and still have a somewhat portable design that can allow you to take them where your adventures might take you.

I’d like to add here that one of the core parts of your research should be going through the reviews of other buyers. You need to read a buying guide to make sure that you’re focusing on the right factors such as the aperture and other capabilities and features.

I needed to look at the amount of expertise I had accumulated. As I said, I wasn’t particularly gifted in this sense, but at least I had the availability and was willing to try my best. I know that learning to operate a new device can be a daunting task but I actually wanted to invest in a life-long journey that would allow me to observe the sky as best as possible.

Since I was a beginner and knew little to nothing about telescopes, in general, I decided to get a refractor. An 80mm aperture seemed to do, especially as I didn’t have the budget for anything more. Even after all this time, it appears to me that the aperture is the feature that governs the end price of the product. Of course, other functionalities such as built-in GPS and the type of mount also have a say in the matter, although I hardly think they are as or more expensive as the optical components.

In the end, what you need to find out is your purpose. Decide on the celestial objects you want to observe and figure out your expertise. Invest some time in researching the model you want to spend your precious cents on.

 

 

Last year or sometime in the past when I was delving into the wonders of the amazing and eternally surprising Internet, I found out that there now were worms that were capable of consuming plastic as fuel. Of course, one of the first questions that passed through my mind was what came out of these worms once their digestion process was wrapped up. I didn’t want to imagine them pooping plastic if you know what I mean.

The fact is that what they do create is entirely organic and can even be used as compost if that’s what you feel like doing. The experiment took place the University of Cambridge, where Federica Bertocchini, a biologist with the Institute of Biomedicine and Biotechnology of Cantabria, Spain, got together with two of her colleagues, Christopher Howe and Paolo Bombelli.

 

The test was rather simple. They would place this outstanding species with several styrofoam cups and bits of plastic in a container and wait for something to happen. Believe it or not, one hundred worms managed to eat about 92 milligrams of plastic in as little as twelve hours. I would call that revolutionary if it weren’t for the services of one hundred worms, which seems a bit too much. Besides, 92 milligrams of plastic is about the size of 4 rice grains, so it’s not really all that impressive. However, given the fact that there’s a high chance that we will end up buried in plastic in the future centuries, it’s still a breathtaking discovery. Who knows what other critters could be capable of doing the same?

It’s also worth noting that the scientists who have performed the experiment have yet to find out exactly how the magic happened. They don’t know whether the worms consumed the plastic just because they wanted to or had developed a certain taste for it beforehand or because there were bacteria in their gut to help them digest it. Some say that it might be both.

The wonderful thing about all of this is that Bertocchini is a beekeeping enthusiast and it ever so happened that she came across several worms that ate the wax produced by the bees. Because she had little to no knowledge about the species or the reason she had found the worms consuming the wax, she kept them in a plastic bag until further notice. That’s how she discovered that the plastic bag also became food for the worms. If that’s not spectacular, I really don’t know what is.

There’s talk of an enzyme or a molecule that might be responsible for the reaction. If that’s the case, maybe scientists could transfer it to other worm species that could finally help us reduce plastic.
