A photomosaic taken by the Curiosity Rover on April 30, 2023 at the Ubajara drill site in Gale Crater, Mars. Rock powder samples drilled here contained substantial amounts of siderite (an iron carbonate mineral). The siderite played a role in ancient carbon cycling processes that impacted conditions at the planet’s surface. Rover tracks in the foreground are 40 cm wide. (Credit: NASA/JPL-Caltech/MSSS)

This is an artist’s impression of the exoplanet 2M1510 (AB) b’s unusual orbit around its host stars, a pair of brown dwarfs. The newly discovered planet has a polar orbit, which is perpendicular to the plane in which the two stars are travelling. Polar planets around single stars had been found before, as well as polar discs of gas and dust capable of forming planets around binary stars. But thanks to ESO’s Very Large Telescope (VLT) this is the first time we have strong evidence that such a planet actually exists in a polar orbit around two stars. The two brown dwarfs appear as a single source in the sky, but astronomers know there are two of them because they periodically eclipse each other. Using the UVES spectrograph on the VLT they measured their orbital speed, and noticed that their orbits change over time. After carefully ruling out other explanations, they concluded that the gravitational tug of a planet in a polar orbit was the only way to explain the motion of the brown dwarfs.

This Hubble image shows Uranus and dynamic aurora activity on 10 October 2022. The centered planet is dominated by a blue hue and a large white region in the lower left. A faint ring is also visible around the planet. Fuzzy blue/purple regions hovering over the planet on the left and ride indicate the presence of aurorae

A collage of three images showing the black expanse of space. Two-thirds of the collage is taken up by the black background sprinkled with small, blurry galaxies in orange, blue, and white. There are two images in a column at the right side of the collage. On the right side of the main image, not far from the top, a very faint dot is outlined with a white square. At the right, there are two zoomed in views of this area. The top box is labeled NIRCam and shows a fuzzy dot at the center of the inset. The bottom box is labeled MIRI and shows a fuzzy pinkish dot.
