| − | For objects at a great distance one can achieve a better view by using a {{w|telescope}} as it is the typical method in {{w|Astronomy}}. Looking through a lens or a {{w|microscope}} in {{w|biology}} and other disciplines does magnify short distant objects. And a {{w|magnifying glass}} works more like a microscope when your eye lense is close to the {{w|focus}} of the magnifying glass, but when looking at distant objects you have to increase the distance between the glass and your eye where the {{w|focal length}} of your magnifying glass must be increased to meters instead of | + | For objects at a great distance one can achieve a better view by using a {{w|telescope}} as it is the typical method in {{w|Astronomy}}.

But in general a {{w|Galilean Telescope}} works at the same principle as a magnifying glass together with your eye lens, the magnifying glass only has to have a long focal length which is optimized for far distances. |
| − | In the comic, the objects being viewed by Megan could be {{w|stars}}, {{w|galaxies}} and the {{w|planets}} of our {{w|Solar System}}. [[Megan]] | + | In the comic, the objects being viewed by Megan could be {{w|stars}}, {{w|galaxies}} and the {{w|planets}} of our {{w|Solar System}}. [[Megan]] takes approach by telescope. [[Beret Guy]] attempts approach it using a step-ladder to get closer to the stars, and then looking at them through his simple hand-held magnifying glass. This approach could be successful only if the stars were a few meters away, so that the ladder would take him within a few centimeters of the study object. In fact the visible stars are several {{w|light years}} away (typically 18-20 orders of magnitude further away) and getting two meters up on a ladder won't make any perceivable difference. |
The title text assumes (for comic effect) that the only thing wrong with Beret Guy's strategy is the instability of the ladder endangering the expensive microscopes used by biologists for {{w|Astrobiology}}. Astrobiology is the study of life (or the possibility thereof) elsewhere in the universe, and here it would be either the planets and moons in our Solar System or {{w|exoplanets}} they needed to look at. This is the second comic related to studying exoplanets in two weeks, the first being [[1517: Spectroscopy]] (see more references there). | The title text assumes (for comic effect) that the only thing wrong with Beret Guy's strategy is the instability of the ladder endangering the expensive microscopes used by biologists for {{w|Astrobiology}}.

| − | Since we cannot go there, they do, of course, not use any microscopes in the direct studies. However, one typical magnifier in biology is the {{w|electron microscope}}, used to study {{w|microbiology}}, and they cost a lot and are very heavy. It is therefore inadvisable to carry one up a ladder, and it could possibly become very expensive if you did try it anyway. | + | Since we cannot go there, they do, of course, not use any microscopes in the direct studies.
