Our @NASAHubble Space Telescope witnessed galactic gridlock happening over 60 million light-years away from Earth in the southern constellation of Crater (the Cup)!
Rather than behaving like rigid structures,
spiral arms—regions of stars that extend from the center of spiral galaxy—are in fact areas of greater density in a galaxy’s disk,
with dynamics similar to those of a traffic jam.
The density of cars moving through a traffic jam increases at the center of the jam,
where they move more slowly.
Spiral arms function in a similar way;
as gas and dust move through areas of greater density,
they become compressed and linger before moving out of them again.

With this new name,
our Mars 2020 rover has now come to life!
Chosen by middle school student Alex Mather,
Perseverance helps to remind ourselves that no matter what obstacles we face,
whether it's on the way to reaching our goals or on the way to Mars,
we will push through.
In Alex’s own words,
⁣
⁣
“We are a species of explorers,
and we will meet many setbacks on the way to Mars.
However,
we can persevere.
We,
not as a nation but as humans,
will not give up.
The human race will always persevere into the future.”

Set to launch July of this year,
Perseverance will help us continue to push the boundaries of human exploration,
while being our window into a new world.
Welcome to the family.⁣
❤️
