False eyes are a thing in nature, for a number of reasons. Confuse predators, make the creature appear larger than it is, etc

Cuttlefish. Allegedly, a creature of this planet.

not an image, but if you're hoping to use a telescope to capture the iss transit (cross) the moon, visit here: https://transit-finder.com/

I'm happy to see it with my own eyes, even if it's just a bright spot in the sky. Have seen it many times.

whoa, amazing they could capture that activity, on another planet
The Bad Astronomer on understanding THIS image:

Image


I should point out that this is NOT a visual image. The scientists who created this image were using a specific data from the star HD 101584 which translated the relative speeds of its dust and gases which are being emitted by this system. The green parts are neutral relative to this star while the blue parts are towards us on Earth and--naturally--the red parts are away from us.

BA uses this to illustrate how there are a lot of astronomical phenomena which ARE hourglass-shaped. This likely means in their creations these were likely once binary star systems which FORCED this hourglass. On the other hand solitary stars like the Sun eventually (in several billion years) will make nice round nebulae like Abell 39:

I will point out that the familiar Ring Nebula:

is likely another hourglass although we happen to be positioned looking almost directly down the throat of one of that hourglass' bulbs.

were there elephants in Spain at that time? Or was it an exotic import?

Good thing I read that. I was ready to yell: "concorde!"

While that is extremely cool, looking at those rock fragments below is all I would need to see to NOPE that right away.

Dragons are not that big. I know because I've seen the desolation of smaug and game of thrones.

WTF is happening to Betelgeuse?

Image

The Bad Astronomer does NOT explain because there is just so much that we simply do not understand.

The above are reprocessed images of the actual surface of Betelgeuse although BA does point out that the apparent PHYSICAL distortion in the later image is most likely only due to the difference in brightness. Well over half of the "surface" is significantly dimmer although by what mechanism (such as starspots) we do not understand. Included in that lack of understanding is what constitutes Betelgeuse's surface. While that star has 20 times the mass of the Sun, Betelguese has nearly a thousand times the Sun's diameter (being roughly the equivalent to the orbit of Jupiter) which means that its average density is about one-TRILLIONTH that of the Sun.

Does this mean that Betelgeuse is on its way to becoming a supernova? Well, yes, eventually but again, we don't know. Perhaps what is happening to Betelgeuse are significant steps towards that event and it is only by fortune that we happen to "next door" (~700 light years which is far enough not to cause any likely problems to us on Earth) to AND have the science knowhow now to observe "this year's" supernova in the Milky Way (which we estimate to average one supernova per year but of course practically all of these have been hidden behind the rest of the galaxy).

Or it may be that we will have to wait over 100,000 years for Betelguese to go supernova.
