I’m Serious

As a paleo-artist, one of my biggest pet peeves are prehistoric whales reconstructed not as whales but as sinewy, snarling, shrink-wrapped marine reptiles. It’s just not a plausible reconstruction, even if it’s highly speculative, and it paints an incorrect image in the public eye. Granted, this is a struggle I’ve exlpored in all forms of paleo-art and reconstructive illustration. But the whales have really been getting to me recently.

Here are some recontructions of Basilosaurus, if you don’t know what I mean (one by Karen Carr, the other by an artist I could not determine):

These snakey, reptilious reconstructions may stem from the fact that Basilosaurus, one of the first early cetaceans to be found, was believed to be a reptile when first discovered (hence the name). Maybe we simply haven’t fully shaken that mindset.

But still! Even the damn Smithsonian, which has such a wonderful collection of ancient cetaceans, is at fault in this:

Don’t even get me started on their recently-closed dinosaur hall. Thank the lord they’re finally renovating that dated piece of crap.

I have struggled to find a way to reconstruct these animals so that they are just a little bit more believeable. Up top I’ve done a really really quick sketch of Dorudon. I tried to not only make its body more streamlined and whale-like (because Dorudon has a lovely, almost but not quite modern-looking skeleton), but I also tried to give it markings similar to what we find on modern cetaceans for camouflage. Because hey, who’s to say they didn’t have ‘em? I tried to make them familiar but not directly copied from any modern species.

Aaaaand end rant.

I’m going to be honest, this it the most I have ever used the science courses I took in undergrad. Glad all those thousands of dollars finally paid off.

A photon checks into a hotel and is asked if he needs any help with his luggage. He says, “No, I’m traveling light.”

Why not just buid a solar panel around the sun to solve all energy problemss?

Behold the Dyson Sphere

Dyson sphere is a hypothetical mega-structure that completely encompasses a star and captures most or all of its power output.

Over the years many variants have been explored:

The simplest such arrangement is the Dyson ring, in which all ‘energy harvesting structures’ share the same orbit.

Add multiple Dyson ring structures and you will get a Dyson swarm.

Now what if you didn’t like a consistent orbit for your structures, you could employ a solar sail to continuously modify its orbit( called a statite ).

Such an arrangement would be known as a Dyson Bubble

Then there is the fictionally popular version - The Dyson Shell, where a uniform solid shell of matter just encapsulates the entire star.

And many many more. But you get the gist.

Could there be Dyson Spheres out there?

When scientists were monitoring the brightness from some stars, they found that it fluctuated in some odd ways like so:

                          Brightness v/s time for KIC 8462852

It is common for such dips to occur since when a planet eclipses a star, there would a drop in the brightness observed from the star.

                       Brightness v/s time for a binary star system

But what was baffling was the duration and period of occurrence of these dips.

Although the main line of rationale remains as asteroid impact remnants or interstellar collisions causing these aberrations in data.

But to say that these could the signs of an alien civilization does remain to be the more entertaining interpretation.

Great Question. Thanks for asking !

Hues in a Crater Slope

by NASA’s Marshall Space Flight Center   Impact craters expose the subsurface materials on the steep slopes of Mars. However, these slopes often experience rockfalls and debris avalanches that keep the surface clean of dust, revealing a variety of hues, like in this enhanced-color image from NASA’s Mars Reconnaissance Orbiter, representing different rock types. The bright reddish material at the top of the crater rim is from a coating of the Martian dust. The long streamers of material are from downslope movements. Also revealed in this slope are a variety of bedrock textures, with a mix of layered and jumbled deposits. This sample is typical of the Martian highlands, with lava flows and water-lain materials depositing layers, then broken up and jumbled by many impact events. This image was acquired by the High Resolution Imaging Science Experiment (HiRISE) camera on Feb. 28, 2011 at 15:24 local Mars time. It is a stereo pair with image ESP_021454_1550. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colo. NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA’s Science Mission Directorate, Washington.

Spectacular collision of stars will create new star in night sky in 2022

1800 years ago two stars were coming together in a huge cataclysmic explosion. The light from that collision will finally arrive on Earth creating a new star in the night sky - dubbed the ‘Boom Star’ - in an incredibly rare event which is usually only spotted through telescopes. Before their meeting the two stars were too dim to be seen by the naked eye, but in 2022, the newly formed Red Nova will burn so brightly in the constellation Cygnus that everyone will be able to to see it. For around six months the Boom Star will be one of the brightest in the sky before gradually dimming, returning to its normal brightness after around two to three years.  Read more

As close as you will ever be to a nuclear explosion

Please join the Department of Awesome Natural Phenomena as they marvel at the jaw-dropping sight of a ‘dirty thunderstorm’ taking place above Sicily’s Mount Etna during its latest eruption on December 3, 2015. Mount Etna is the tallest active volcano on the European continent.

A dirty thunderstorm, also known as volcanic lightning, is the result of electrical charges generated by the collision of rock fragments, ash, and ice particles in a volcanic plume. These collision produce a static charge in the same way that colliding ice particles do during regular thunderstorms.

Freelance photographer Marco Restivo captured this incredible image by combining a sequence of five separate photos.
