  5. A small black circle sits at the center of an illustration, representing a black hole. A thin blue spiral shows energetic material swirling around the black hole. The edge of the spiral gives way to a larger, thicker and more diffuse and broader red and orange cloud. Shooting up from the black hole, perpendicular to the cloud, is a narrow jet of radiation shown in bluish white.

  6. A nebula made up of cloudy gas and dust in the form of soft and wispy clouds and, in the center, thin and highly detailed layers pressed close together. Large, bright stars surrounded by six long points of light are dotted over the image, as well as some small, point-like stars embedded in the clouds. The clouds are lit up in blue close to the stars; orange colors show clouds that glow in infrared light.

  8. Temperate exoplanet LHS 1140 b may be a world completely covered in ice (left) similar to Jupiter’s moon Europa or be an ice world with a liquid substellar ocean and a cloudy atmosphere (centre). LHS 1140 b is 1.7 times the size of our planet Earth (right) and is the most promising habitable zone exoplanet yet in our search for liquid water beyond the Solar System. Image credit: B.

  9. The high-resolution ELT instrument ANDES (formerly known as HIRES), will allow astronomers to study astronomical objects that require highly sensitive observations. It will be used to search for signs of life in Earth-like exoplanets, find the first stars born in the Universe, test for possible variations of the fundamental constants of physics, and measure the acceleration of the Universe's expansion.

  12. This artist’s impression shows the formation of a gas giant planet embedded in the disk of dust and gas in the ring of dust around a young star. A University of Michigan study, led by U-M astronomer Gabriele Cugno, aimed the James Webb Space Telescope at a protoplanetary disk surrounding a protostar called SAO 206462, hoping to find a gas giant planet in the act of forming.

  13. On the left are three yellow half-rings, which show how the shape of the circumstellar gas cloud changes as it expands with time. At first, shown in the innermost ring, the gas cloud is a simple torus (a 3D ring). Later, shown in the middle ring, 16 lumps of equal size are beginning to form, like a string of beads. Finally, shown in the outermost ring, the 16 lumps become distinct clumps. A flattened gas cloud extends from the line of clumps. The right side shows vortices, or regions of rapidly rotating flow. At first, there is no rotation in the flow, and so there are no vortices. The first blue ring therefore aligns with the beaded string on the left (the middle yellow half-ring). Sixteen arcs align with the 16 beads on the mirrored side. The arcs then pinch off into isolated vortex loops, which correspond to the clumps on the mirrored side. The simulation shows the shape of the gas cloud on the left and the vortices, or regions of rapidly rotating flow, on the right. Each ring represents a later time in the evolution of the cloud. It shows how a gas cloud that starts as an even ring with no rotation becomes a lumpy ring as the vortices develop. Eventually the gas breaks up into distinct clumps.

  15. This artist impression shows ultra-fast winds blasting out from the center of galaxy Markarian 817. These winds, moving at many millions of kilometers per hour, clear out interstellar gas from a vast region of space. Without this gas, the galaxy can’t form new stars and the black hole in the galactic center has little left to eat. Image credit: ESA (acknowledgement: work performed by ATG under contract to ESA)

  17. The space junk appears as many small white points surrounding Earth, which has bright blue oceans and green and brown continents. The space junk is thick enough to form a cloud that obscures most of the black background when viewed from the edges around Earth.
