Completely invisible,
yet unbelievably influential.

According to new research from @sofiatelescope,
spiral galaxies like the Milky Way are shaped by magnetic fields.
These magnetic fields are invisible to the human eye.
⁣
⁣
However,
by combining imagery from @NASAHubble,
the Nuclear Spectroscopic Array and the Sloan Digital Sky Survey,
the magnetic fields become apparent.
In this image,
scientists measured the magnetic fields along the spiral arms of the galaxy called NGC 1068.
The fields are shown as streamlines that closely follow the circling arms.⁣

Why did engineers push this rocket tank beyond its limits —
on purpose?⁣
⁣
This is an exact copy of the liquid hydrogen tank used on our Space Launch System (@NASA_SLS)
rocket,
which will fly #Artemis missions to the Moon.
A team from @NASA_Marshall and Boeing put the tank in a 215-foot-tall test stand,
fitted it with sensors and simulated the stress a rocket will experience during launch and flight.
⁣
⁣
After millions of pounds of compression,
tension and bending forces —
260%
more than expected flight loads —
engineers detected a buckling point,
which then ruptured.
"This data will benefit all aerospace companies designing rocket tanks,”
said the SLS tank's lead engineer.
This test will help safely and efficiently evolve the rocket's design for future space missions.

Zoom in to Jupiter's clouds with our @NASAJuno mission!

⁣
This image was taken by the spacecraft as it flew just 3,200 miles (5,200 km)
from the giant planet's northern latitudes during a close flyby on Nov.
3,
2019.
Small pop-up storms can also be seen rising above the lighter areas of the clouds,
most noticeably on the right side of the image.
