An illustration of a purple star-forming nebula.
More
A large, amorphous blob in a circular shape has layers of transparent, hazy color overlapping. The different layers start with a slight blue and dark purple around the outer rim and move inward to brighter purples. While white dots representing stars speckle the whole image, in the upper left part of this shape is a bright white circular cloud with more pronounced and larger stars grouped together.

An illustration has an elongated oval in light blue stretching across the center, outlined in a darker blue. Behind the strip is a diffuse, very light blue cloud that fades into a light blue and then a darker blue. All over the image are white speckles, representing stars.

A graphic of ASTHROS is shown in light and dark shades of blue and has a main cage-like body with large, rectangular panels stemming from its sides, small square panels on its lower half, and a thin structure protruding from the top. (This structure will attach to a large balloon). A telescope protrudes from the back of the structure.

An illustration of NASA's TESS spacecraft.
More
This illustration of NASA's TESS shows the spacecraft in shades of blue. The multi-sided, cylindrical shaped main body of the satellite has two solar array "wings," each extending out from the sides of the satellite which is attached to an open, cone shaped bottom piece. Nestled inside the cone are four squares which show the relative positions of TESS’s cameras.

An illustration of a planetary nebula.

A subtly transparent, colorful hourglass shape has a central point that is a white circle surrounded by bright, white haze. Extending outward from the center in opposite directions are plums of color that form the hourglass shape. The central part of each plume starts as an icy, light blue and fades upward into a purple color and outward into red. White dots representing stars speckle the image.
Planetary Nebula (Version Two, Purple)
A vertical oval illustration of a supernova.
More
A large vertically-oriented oval shape with rounded waves around the edge, this graphic has a flower-like appearance. Smaller transparent circles with the same wavy edge are layered inward to create an inner starburst shape. The outer rings are a very light green color and they move inward into different light blue colors and finally to a center starburst shape that is a dark blue. White dots representing stars speckle the image.

A transparent, colorful hourglass shape has a central point that is a white circle surrounded by bright, light haze. Extending out from the center in opposite directions are plumes of color that form the hourglass shape. Each starts as blue near the central circle, then fades into a purplish pink color. The outline of the hourglass shape is wavy and white dots representing stars speckle the image.
Planetary Nebula (Version Two, Pink)
An illustration of a blazar, or an active galactic nucleus that emits a powerful radiation jet. 
More
A graphic shows a diffused, dark purple ring that fades inward to a bright purple, a lighter purple, and eventually to a light blue gradient. At the center of the circular object is a small black circle from which a transparent beam is emitted, starting as a transparent blue and moving into green, yellow, orange and red.
Blazar
An illustration of a short gamma-ray burst caused by merging neutron stars.
More
At the center of this graphic of a short gamma-ray burst is a black dot representing a black hole. A cloud of debris, represented as a yellow-ish filled-in figure eight is centered on the black hole and tilted 45 degrees to the right. A pair of white-ish, cone-shaped jets are aligned with the figure eight and extend above and below the black holes. Additional debris is represented as a blue oval and a filled-in eternity symbol, both centered on the black hole and tilted 45 degrees to the left.
