For many ordinary objects, one can achieve a better view in two ways: (#1) by looking at the object from a distance through a telescope, or (#2) by approaching the object and looking at it through a magnifying glass. Magnifying glasses typically have a very short resolving distance, usually on the order of a tenth of a meter, so approach #2 is effective only in the case where you can get very close to the object in question.

In the comic, the objects being viewed are celestial bodies. Megan takes approach #1, looking at them through a telescope. Beret Guy attempts approach #2, using a step-ladder to try to get close to the celestial bodies, and then looking through a magnifying glass. This approach could be successful only if the celestial bodies were within a few meters of us. In fact they are many orders of magnitude further away than that, and Beret Guy's use of the ladder would yield no appreciable improvement in his view of celestial bodies through a magnifying glass. The history of astronomy is filled with drastic underestimates of distances to celestial bodies, but none quite so comical as Beret Guy's very extreme underestimate.

Although Beret Guy's approach to astronomy seems ill-informed, previous comics such as 1486: Vacuum and 1490: Atoms show that his unusual understanding of science actually works. The comic could also be a reference to the fact that space-based telescopes are much smaller than ground-based telescopes: for example, the primary mirrors of the Hubble Space Telescope and the W. M. Keck Observatory are 2.4 m and 10 m respectively.

The title text assumes (for comic effect) that the only thing wrong with Beret Guy's strategy is that the ladder would be unstable, when in fact his approach would be quite obviously bound to fail for the many reasons described above.

Astrobiology is the study of life (or possibility thereof) elsewhere in the universe.

It might be interesting to note that a lot of developments in "terrestrial" biology were made by the use of a simple microscope (similar to a magnifying lens), so Beret Guy's approach might be an attempt to build on that.

For a telescope you can be far away, for a magnifying glass or microscope you need a ladder to be nearer to the stars. Microscopes are for biology, telescopes for astronomy. They have got a similar purpose, but look and are applied differently. Sebastian -- 07:09, 8 May 2015 (UTC)

Seemed like another example of Beret guy contradicting how things work, like how he blows into the power cord and inflated a computer, or how he plugged a cord into a power outlet labeled "COFFEE" and coffee came out. 07:19, 8 May 2015 (UTC)

Yes obviously this approach works for Berret Guy because this is what he does. Explanation lacks this fact. --Kynde (talk) 07:44, 8 May 2015 (UTC)
Soup, wasn't it? But yes, for some reason he can actually use a stepladder to get a closer look (and a better one, thanks t the magnifying glass) on the "curtain of the night", which for him is actually within reach. As if it is just like a stage back-cloth with some form of star-effect (holes and backlight or sewn-in LEDs) as far as he is concerned.
But what I was actually coming here to say was regarding Astrobiology being a portmanteu (as currently in the explanation). I'm not sure I'd call it that. It's really a perfectly normal compound description of a study area, like many others in science, used to clarify what subset of biology it is (e.g. paleobiology being the biology of historic organisms, more or less, coming roughly from the greek for "old life study"). Although it does rather hint at it's "the biology of stars themselves", as opposed to the perhaps more accurate exobiology ("outside life study") when it comes to off-Earth life not in (or being) actual stars; or xenobiology ("strange life study"), although that does tend to include oddments of obscure Earth biology and artificial life as well and really doesn't mean the study of extra-terrestrial organisms... 08:00, 8 May 2015 (UTC)
Astrobiology is a perfectly normal word. http://en.wikipedia.org/wiki/Astrobiology. 08:49, 8 May 2015 (UTC)
Moreover, the wording (which I deleted) implied that Randall invented the word, or that the word is very new: "the word "astrobiology" is the joining of the prefix astro- and biology and refers to ...". Now it says "Astrobiology is ...". 13:52, 8 May 2015 (UTC)

A minor comment on the incorrect use of the word portmanteau in the explanation so far: it is defined as a word formed by merging the sounds and meanings of two different words, wikipedia:portmanteau; however, astro- is a combining form of the the greek word aster meaning star, used to form compound words, such as astro-bio-logy (aster-bios-logos: star-life-word). See 1485 for an example of the correct use of portmanteau. (someone beat me to it while i was editing this ;-)) 08:07, 8 May 2015 (UTC)

Thank you. --Forrest (talk)09:14, 08 May 2015 (UTC)

You could view the comic as a theatrical production, Megan's telescope as a prop, and Beret guy is just inspecting the backdrop. The ladder is for comic and aesthetic effect (talk) (please sign your comments with ~~~~)

Aaaaa. Astronomers do not touch telescopes while observing. 09:23, 8 May 2015 (UTC) Cameron

My first association was the Hubble Space Telescope: Even though there are huge telescopes on earth, most (all?) of them are inferior to the relatively small telescope a few km above earth's surface. Beret Guy could have tried to achive the same effect by climbing a ladder. Epaminaidos (talk) 09:58, 8 May 2015 (UTC)

I'm with - I'm not sure that those white dots are stars. My first thought was that they were flecks of dirt or something on the wall or on the inside of a dome. What Megan is doing there with that huge telescope I don't know, but a telescope of that size is not usually used outdoors where stars can be seen down to the horizon. --RenniePet (talk) 10:35, 8 May 2015 (UTC)

That seems to be the reason why the Good Telescopes are always on mountains – nearer to the stars and no ladder needed ;-). --DaB. (talk) 11:32, 8 May 2015 (UTC)

I believe the good telescopes are high so they get less atmospheric disturbances. The height of a mountain will still be insignificant compared to distances measured in light years.--The man they call Jayne108.162.237.183 11:50, 8 May 2015 (UTC)

I actually thought that maybe physics just work differently for him so he was actually standing among the stars (like someone might stand among lightning bugs) and actually examining them. (talk) (please sign your comments with ~~~~)

I don't think the titletext has anything to do with shaking about, I think it's a joke about people being nervious about breaking the microscope. Halfhat (talk) 15:57, 8 May 2015 (UTC)

My take is Beret Guy is using "cartoon physics" or in this case "comic physics". The first few panels we assume the stars are in the distance. Since we are looking at a 2D representation (drawing), we can't be sure. But our past experiences with the night sky and with pictures or situations such as this guides our perception. However, because of Beret Guy's weird take on everything, he perceives the stars as they actually ARE in the comic: just white dots on a black background, kind of like a poor man's planetarium. He wants to get a closer look at some that are higher up on the wall/background so climbs up a ladder and uses his magnifying glass. It's a little like the cartoon where the coyote paints a tunnel on a rock, thinking the roadrunner will run into it. Instead, the roadrunner just goes through the painted tunnel like it was real. 19:34, 8 May 2015 (UTC)Pat

It's also possible that Megan and her telescope are part of a backdrop of some sort - I don't think she moves at all in the comic. -- 21:44, 8 May 2015 (UTC)

She does move; look closely at her hair. One could say she is looking "sidelong" at Beret Guy, which is a gesture that communicates something. Taibhse (talk) 11:28, 9 May 2015 (UTC)

Woah, that's really a lot of discussion over this tiny comic. Nk22 (talk) 19:06, 8 May 2015 (UTC)

I'd love to see a good explanation of the optics at play and the differences between telescopes and magnifying lenses. E.g. from Focal length: In most photography and all telescopy, where the subject is essentially infinitely far away, longer focal length (lower optical power) leads to higher magnification and a narrower angle of view; conversely, shorter focal length or higher optical power is associated with a wider angle of view. On the other hand, in applications such as microscopy in which magnification is achieved by bringing the object close to the lens, a shorter focal length (higher optical power) leads to higher magnification because the subject can be brought closer to the center of projection. And the reference to "resolving distance" seems like a misinterpretation. For a good time, watch Stepwise magnification by 6% per frame into a 39 megapixel image. In the final frame, at about 170x, an image of a bystander is seen reflected in the man's cornea. Nealmcb (talk) 15:11, 9 May 2015 (UTC)

If you (or anyone else) know enough about this, it would be great if you would correct the misinterpretation and maybe add some details. The above could be linked to via wiki. Or it could be a trivia section, if it is too much in the main explanation. I do not know enough about this to make a good explanation. --Kynde (talk) 08:24, 11 May 2015 (UTC)
The focal length doesn't fit to a telescope or microscope in the same way as it does to a single lense like a magnifying glass. The major difference is the difference of the focus. A microscope does focus on an object very close to you, a telescope is set to an infinite focus. And a simple lense just increases your angle of view. I will give a try on this even more complex physics here. --Dgbrt (talk) 20:34, 11 June 2015 (UTC)

Statue in Canberra, Australia of an astronomer with magnifying glass -- Multimotyl (talk) (please sign your comments with ~~~~)

You're all forgotten how early astronomy was done. At the turn of the century, photographs were taken through the telescope, developed, and only later analyzed closely - with a magnifying glass - as part of Astrophotography! This allowed for careful tracking and analysis of the many stars that might be visible from just one frame. (It also allowed observation of the same area of the sky at different days, or even at different years, to see which stars were moving relative to others.) For more, look into The Women Who Mapped the Universe Jorgbrown (talk) 20:08, 11 May 2015 (UTC)

It seems like this explanation ought to consider that perhaps they are standing in a room painted black with white stars drawn on the ceiling (or perhaps in the dark projected/simulated like a planetarium) such that Beret Guy's use of the magnifying glass actually does bring him close enough to observe. Although this is unlikely, it seems possible. JohnHawkinson (talk) 00:13, 25 May 2020 (UTC)
