A Chandra supernova in the sky...
This Chandra X-ray Observatory (@nasachandraxray)
image captures a star in the constellation Cassiopeia that was obliterated by an explosion.
What's left behind is this multicolored,
three-dimensional object:
a supernova remnant.
⁣
⁣
Tycho's supernova remnant —
named for Danish astronomer Tycho Brahe,
among the first to spot it in 1572 —
was a Type Ia,
which occurs when a white dwarf star pulls material from,
or merges with,
a nearby companion star until a violent explosion is triggered,
sending debris hurtling into space.⁣
⁣
The image is providing clues to what caused the remnant's intriguing pattern of bright clumps and fainter areas.
To emphasize the clumps in the image and the three-dimensional nature of Tycho,
scientists selected two narrow ranges of X-ray energies to isolate material (silicon,
colored red)
moving away from Earth,
and moving towards us (also silicon,
colored blue).
The other colors in the image (yellow,
green,
blue-green,
orange and purple)
show a broad range of different energies and elements,
and a mixture of directions of motion.

“To all those reaching to new heights:
yes you can.”
👩‍🚀💪 #MondayMotivation brought to you by @Astro_Christina.

On Oct 18,
our @NASAAstronauts Christina Koch (in the suit with red stripes)
and Jessica Meir performed the first #AllWomanSpacewalk in history.
They replaced a faulty battery charge/discharge unit that failed to activate after a previous spacewalk.

Thanks iThis was the fourth spacewalk for @Astro_Christina and the first for @Astro_Jessica.
Their tasks set the stage for our #Artemis missions where history will be made once again when the first woman steps foot on the Moon.

Saturn on Insta vs.
Saturn IRL 👀⁣

An illusion of perspective,
Saturn’s moon Tethys seems to hang above the planet's north pole in this view from @NASAJPL's Cassini spacecraft that was captured on Jan.
26,
2015.
Tethys is actually farther away than Saturn in this image.
Lacking visual clues about distance,
our brains place the moon above Saturn's north pole,
but like all of Saturn's major moons and its ring system,
Tethys actually orbits almost exactly at the planet’s equator.⁣
