Mind Blowing - Blog Posts

I listen to subliminals almost exclusively on my phone, and I just realized I can layer them on my laptop just by doing this.

Earth Facts that Live Rent-Free in Our Heads

Earth is a big weird planet. With so much going on, it’s easy to forget some of the many, many processes happening here. But at the same time, some stuff is so unexpected and just plain strange that it’s impossible to forget. We asked around and found out lots of people here at NASA have this problem.

Here are some facts about Earth that live rent free in our heads:

Earth has a solid inner core that is almost as hot as the surface of the Sun. Earth’s core gets as high as 9,800 degrees Fahrenheit, while the surface of the Sun is about 10,000 degrees Fahrenheit.

Dust from the Sahara fertilizes the Amazon rainforest. 27.7 million tons blow all the way across the Atlantic Ocean to the rainforest each year, where it brings phosphorus -- a nutrient plants need to grow.

Ice in Antarctica looks solid and still, but it’s actually flowing -- in some places it flows so fast that scientific instruments can move as much as a kilometer (more than half a mile!) a year.

Speaking of Antarctica: Ice shelves (the floating part of ice sheets) can be as big as Texas. Because they float, they rise and fall with the tide. So floating ice as big as Texas, attached to the Antarctic Ice Sheet, can rise and fall up to ~26 feet!

Melting ice on land makes its way to the ocean. As polar glaciers melt, the water sloshes to the equator, and which can actually slow the spin of Earth.

Even though it looks it, the ocean isn’t level. The surface has peaks and valleys and varies due to changes in height of the land below, winds, temperature, saltiness, atmospheric pressure, ocean circulation, and more.

Earth isn’t the only mind-blowing place out there. From here, we look out into the rest of the universe, full of weird planets and galaxies that surprise us.

Say hello to spiral galaxy NGC 1097 👋

About 45 million light-years away, in another corner of the cosmos, lies spiral galaxy NGC 1097. Though this Hubble Space Telescope image zooms in toward the core, the galaxy’s vast spiral arms span over 100,000 light-years as they silently sweep through space. At the heart of this galaxy lurks a black hole that is about 100 million times as massive as the Sun.

The supermassive black hole is voraciously eating up surrounding matter, which forms a doughnut-shaped ring around it. Matter that's pulled into the black hole releases powerful radiation, making the star-filled center of the galaxy even brighter. Hubble’s observations have led to the discovery that while the material that is drawn toward NGC 1097’s black hole may be doomed to die, new stars are bursting into life in the ring around it.

This sparkling spiral galaxy is especially interesting to both professional scientists and amateur astronomers. It is a popular target for supernova hunters ever since the galaxy experienced three supernovas in relatively rapid succession — just over a decade, between 1992 and 2003. Scientists are intrigued by the galaxy’s satellites — smaller “dwarf” galaxies that orbit NGC 1097 like moons. Studying this set of galaxies could reveal new information about how galaxies interact with each other and co-evolve.
