Chasing Storms at 17,500mph

Flying 250 miles above the Earth aboard the International Space Station has given me the unique vantage point from which to view our planet. Spending a year in space has given me the unique opportunity to see a wide range of spectacular storm systems in space and on Earth. 

The recent blizzard was remarkably visible from space. I took several photos of the first big storm system on Earth of year 2016 as it moved across the East Coast, Chicago and Washington D.C. Since my time here on the space station began in March 2015, I’ve been able to capture an array of storms on Earth and in space, ranging from hurricanes and dust storms to solar storms and most recently a rare thunder snowstorm.

For a moment, that black and white photo should seem like a full color image. (You have to keep both the image and your head very still).

This illusion was used in the new BBC Four series Colour: The Spectrum of Science.

It demonstrates a phenomenon called “cone fatigue.” When we stare at the purple hillside in picture above, photoreceptors in our eyes called cones are stimulated. They send a signal to our brains that says “You’re looking at something purple.” But the sensing ability of those cones decreases the longer we stare at the image - those receptors are, in a way, temporarily used up.

Then when we look at the black and white image, those same cones can’t detect any purple light. Instead they sense the color that remains: green.

“Consensual sex” is just sex. To say that implies that there is such a thing as “non consensual sex”, which there isn’t. That’s rape. That is what it needs to be called. There is only sex or rape. Do not teach people that rape is just another type of sex. They are two very separate events. You wouldn’t say “breathing swimming” and “non breathing swimming”, you say swimming and drowning.

I never thought I’d have competition for the most startorial Emily on the planet, but Emily Lakdawalla, Senior Editor and Planetary Evangelist at the Planetary Society (and the third most followed astronomer on twitter) is bringing it! After winding up with the Fibonacci spiral dress by @shenovafashion, she is dazzling in the super star dress from Belle Neptune, as posted by the Planetary Society on Instagram.

I haven’t identified the source image yet, but I suspect it is a globular cluster, perhaps one with a lot of unusually blue stars like Messier 53.

Watch this space to see Emily’s closest approach (and who she joins forces with) tomorrow!

This is the coolest outer space animation ever. It shows the Crab Supernova explosion, happened in 1054, and its evolution into the remnant it is now - called the Crab Nebula. Basically a thousand years speeded up into less than a minute.

Modern understanding that the Crab Nebula was created by a supernova, an explosion of a massive supergiant star, dates to 1921 when Carl Otto Lampland announced he had seen changes in its structure. This eventually led to the conclusion that the creation of the Crab Nebula corresponds to the bright SN 1054 supernova recorded by Chinese astronomers in AD 1054. There is also a 13th-century Japanese reference to an appearance of a new or “guest” star in Meigetsuki. It was then so bright it was visible during the daytime for 23 days.

Science is so amazing, but it’s being de-funded around the world. We hope to make a difference with this video:
