Trees are like puppies

I run past young trees like these on one of my routes, and each time I can't help but think that these trees are like puppies. Just like puppies have oversized paws, these trees seem to have oversized leaves that they're going to grow into over time.

My favourite science shows

When I sit down to have lunch with our kids, I typically watch my favourite science shows on YouTube. I have three (give or take): PBS Eons;SciShow (along with SciShow Space); andIt’s Okay To Be Smart. I’m pretty sure our kids enjoy the shows, I certainly do. I also realised that there’s some overlap between…… Continue reading My favourite science shows

Beautiful Cosmic Disorientation

This Hubble image shows how young, energetic, massive stars illuminate and sculpt their birthplace with powerful winds and searing ultraviolet radiation. In this Hubble portrait, the giant red nebula (NGC 2014) and its smaller blue neighbor (NGC 2020) are part of a vast star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, located 163,000 light-years away. The image is nicknamed the “Cosmic Reef,” because it resembles an undersea world. The sparkling centerpiece of NGC 2014 is a grouping of bright, hefty stars, each 10 to 20 times more massive than our Sun. The stars’ ultraviolet radiation heats the surrounding dense gas. The massive stars also unleash fierce winds of charged particles that blast away lower-density gas, forming the bubble-like structures seen on the right. The stars’ powerful stellar winds are pushing gas and dust to the denser  left side of the nebula, where it is piling up, creating a series of dark ridges bathed in starlight. The blue areas in NGC 2014 reveal the glow of oxygen, heated to nearly 20,000 degrees Fahrenheit by the blast of ultraviolet light. The cooler, red gas indicates the presence of hydrogen and nitrogen. By contrast, the seemingly isolated blue nebula at lower left (NGC 2020) has been created by a solitary mammoth star 200,000 times brighter than our Sun. The blue gas  was ejected by the star through a series of eruptive events during which it lost part of its outer envelope of material. The image, taken by Hubble’s Wide Field Camera 3, commemorates the Earth-orbiting observatory’s 30 years in space.

Astrophysicist Katie Mack published a wonderful video titled “Disorientation” just over a year ago that combines cosmic images with her poem of the same name. https://youtu.be/2wT1-bRj9wI I found out about the video while watching another terrific video commemorating the Hubble Telescope’s 30 anniversary on the It’s Ok To Be Smart channel, titled “Fly Through a…… Continue reading Beautiful Cosmic Disorientation
