This artist’s concept illustrates how tightly the three stars in the TIC 290061484 system orbit each other. If they were placed at the center of our solar system, all the stars’ orbits would be contained a space smaller than Mercury’s orbit around the Sun. The sizes of the triplet stars and the Sun are also to scale. Image credit: NASA’s Goddard Space Flight Center.

This Hubble image shows NGC 4694, a lenticular galaxy some 54 million light-years in the constellation of Virgo. The color image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.
