Glass eels typically refers to an intermediary stage in the eel’s complex life. The term typically refers to a transparent glass eel of the family Anguillidae. These are the freshwater eels that spawn in the ocean, and then enter estuaries as glass eels and swim upstream to live in freshwater during their juvenile growth phase. As the glass eels enter freshwater they start to become pigmented and are typically referred to as elvers. The elvers grow larger and are referred to as yellow eels, which are the juvenile stage of eels before their reproductive maturation begins.

Ganymede and Callisto are similar in size and are made of a similar mixture of ice and rock, but data from the Galileo and Voyager spacecraft show that they look different at the surface and on the inside. Just like Earth and Venus, Ganymede and Callisto are twins, and understanding how they were born the same and grew up to be so different is of tremendous interest to planetary scientists.

Ganymede and Callisto’s evolutionary paths diverged about 3.8 billion years ago during the Late Heavy Bombardment, the phase in lunar history dominated by large impact events. Impacts during this period melted Ganymede so thoroughly and deeply that the heat could not be quickly removed. All of Ganymede’s rock sank to its center the same way that all the chocolate chips sink to the bottom of a melted carton of ice cream. Callisto received fewer impacts at lower velocities and avoided complete melting. Ganymede is closer to Jupiter and therefore is hit by twice as many icy impactors as Callisto, and the impactors hitting Ganymede have a higher average velocity.

Striped icebergs are quite a view. They can form a couple different ways. Blue stripes occur when layers of ice melt and refreeze so fast that no bubbles — which scatter light to give icebergs their white appearance — are created. If the water that freezes is rich in algae, the bands may appear green. Black, brown, and yellow striations are created by sediments picked up by a glacier as it runs down a mountain into the ocean.

though usually hidden to the human eye, naturally occurring marine biofluorescence can be seen under certain wavelengths of light (like ultraviolet) which causes the cells of the organisms seen here to absorb the light — and some of the photon’s energy — and then emit back a now less energetic light with a longer wavelength and thus different colour.

(biofluorescence is not be confused with bioluminescence, which is a  chemical reaction endemic to an organisms that causes it to glow.)

Woop, I should probably put this here too. Keeping up with progress is probably kinda easier when there’s progress to show. Maybe.

Walk done!

This is amazing!

My first finished commission, courtesy of prehistoric-birds!

Here we have an Archaeopteryx showing off all the little details we know about it now, including the leg feathers, the black-tipped wing feathers, and the V-shaped split on the tail fan, along with a relatively accurate depiction of its wing feathers (give or take).

Oh my god its little head and eyes

It has a flat shell on top like a stupid hat and its giant mantle looks like a big fat poncho

What the FUCK how is this real

This old-ass drawing will help you understand what we’re seeing but clearly doesn’t capture the magic

So great: Rhode Island Public Radio reporter Bradley Campbell draws the storytelling structures of iconic public radio shows on napkins – it’s like Kurt Vonnegut’s shapes of stories meet David Byrne’s diagrams of the human condition.
