Liquid oxygen is magnetic

Liquid oxygen sticks between the poles of a strong magnet until it boils away into its gas state. This is because it has unpaired electrons, which make each oxygen molecule a tiny magnet with a dipole. Normally, when oxygen is in a flask or in the air, these microscopic magnets point in all directions, cancelling out and meaning that there’s no net magnetic field. When it pours over the permanent magnet, the magnetic molecules all slightly align, creating an induced magnetic field, which reacts with the permanent magnet, making the oxygen stick to the poles. This is called paramagnetism. Click here to watch the video.

Productivity culture will deceive you (especially if you are particularly high-functioning or a former Gifted Kid) into thinking that any use of your time that can’t be monetized or leveraged for your personal advancement is worthless, and I’m here to tell you that’s the devil talking. Do shit because you like it.

Solar System: 10 Things to Know

Movie Night

Summer break is just around the corner. Hang a sheet from the clothesline in the backyard and fire up the projector for a NASA movie night.

1. Mars in a Minute

Back in the day, movies started with a cartoon. Learn the secrets of the Red Planet in these animated 60 second chunks.

2. Crash of the Titans

Watch two galaxies collide billions of years from now in this high-definition visualization.

3. Tour the Moon in 4K

Wait for the dark of the waning Moon next weekend to take in this 4K tour of our constant celestial companion.

4. Seven Years of the Sun

Watch graceful dances in the Sun’s atmosphere in this series of videos created by our 24/7 Sun-sentinel, the Solar Dynamic Observatory (SDO).

5. Light ‘Em Up

Crank up the volume and learn about NASA science for this short video about some of our science missions, featuring a track by Fall Out Boy.

6. Bennu’s Journey

Follow an asteroid from its humble origins to its upcoming encounter with our spacecraft in this stunning visualization.

7. Lunar Landing Practice

Join Apollo mission pilots as they fly—and even crash—during daring practice runs for landing on the Moon.

8. Earthrise

Join the crew of Apollo 8 as they become the first human beings to see the Earth rise over the surface of the Moon.

9. Musical Descent to Titan

Watch a musical, whimsical recreation of the 2005 Huygens probe descent to Titan, Saturn’s giant moon.

10. More Movies

Our Goddard Scientific Visualization Studio provides a steady stream of fresh videos for your summer viewing pleasure. Come back often and enjoy.

Often times you look at really pretty images of Supernova remnants (what is left after a supernova explosion) and are blown away by their magnificence. But the sad truth is that there are not a lot of these supernovas that we can observe in such great detail.

On the bright side, in general there are lots of supernovas to observe in the universe. And the above is a spectacular time-lapse of the Supernova SN 2015F illustrating how the Luminosity of a Supernova varies with time.

Arp 188 and the Tadpole’s Tail

Drops that impact a very hot surface will surf on their own vapor, and ones that hit a very cold surface will freeze almost immediately. But what happens when the temperature differences aren’t so extreme? Scientists explored this (above) by dropping room-temperature water droplets onto a cool surface – one warmer than the freezing point but cooler than the dew point at which water condenses. 

They found that impacting drops formed a triple halo of condensate (right).  The first and brightest ring forms at the radius of the drop’s maximum extent during impact. The second band forms from water vapor that leaves the droplet at impact. As that vapor cools, it condenses into a second band. The final, dimmest band forms as the droplet stabilizes and cools. It’s the result of water vapor near the droplet continuing to cool and condense. (Image and research credit: Y. Zhao et al.; via Nature News; submitted by Kam-Yung Soh)
