ALT A gaseous planet in the right foreground, seen mostly in silhouette, orbits a small, white star in the background at left. The star is surrounded by a thin, bright white disk tilted from lower left to upper right. A semi-transparent tail of material comes off the planet toward the upper right. Distant stars dot the black background of space.
ALT Line graph titled HS 0209+0832, White Dwarf Atmosphere Features. Hubble Space Telescope spectral data is shown in white, compared with a best fit model in red. The vertical y axis is labeled Brightness, with brighter at the top and dimmer at the bottom. The horizontal x axis is labeled Wavelength of light, angstroms. One-third of the way across the x axis is labeled 1452. To the right of the graph’s center is angstrom label 1453, and the right edge of the graph is labeled angstrom 1454. Three dramatic dips in the spectrum are labeled with element names and abbreviations: Niobium, Nb, Nickel, Ni, and Calcium, Ca. The niobium Hubble data and model match well and appear to the right of the 1452 angstrom label. To the right, Hubble’s nickel data is much dimmer than the model, appearing just left of the graph’s center. Hubble’s data for calcium is a little dimmer than the model, and appears to the right, about one-sixth of the way from the right-hand edge of the graph.
ALT Illustration divided into quadrants, showing the evolution of a star system over time. The upper left is labeled 1. Sun-like star. It shows a small, glowing yellow star centered with other faint stars in the background of space. The upper right quadrant is labeled 2. Red giant. It shows a much larger, puffy orange-red star with a yellow glow within. The bottom left quadrant is labeled 3. White dwarf with second-generation protoplanetary disk, showing a bright white star, smaller than the original Sun-like star, surrounded by a glowing dusty blueish-white disk that is brighter closer to the star. The lower right quadrant is labeled 4. Accretion of a second-generation planet. It shows a similar star to quadrant 3, but the disk is reduced in size and is more purple in color. A planet orbits to the lower left of the star. The planet is larger than the star and has a faint tail leading back to the disk around the star.
ALT A dense galaxy cluster fills the image, with bright galaxies concentrated near the centre and numerous more distant galaxies visible throughout the dark background, including several faint, elongated arcs distorted by gravitational lensing.
