The image shows galaxy Arp 148, captured by NASA’s Spitzer and Hubble telescopes. Specially processed Spitzer data is shown inside the white circle, revealing infrared…
Brown dwarfs are often called “failed stars.” They form like stars but are not massive enough to fuse hydrogen into helium as stars do. More…

The Blue Ring Nebula, which perplexed scientists for over a decade, appears to be the youngest known example of two stars merged into one. In…
This artist’s impression shows LTT 9779b near the star it orbits and highlights the planet’s ultra-hot (2000 Kelvin) day-side and its quite toasty night-side (around…
WD 1856 b, a potential planet the size of Jupiter, orbits its dim white dwarf star every 36 hours and is about seven times larger.…
The star-forming nebula W51 is one of the largest “star factories” in the Milky Way galaxy. Interstellar dust blocks the visible light emitted by the…
NASA’s Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope have found a young Neptune-size world orbiting AU Microscopii, a cool, nearby M-type dwarf…
This image shows two massive black holes in the OJ 287 galaxy. The smaller black hole orbits the larger one, which is also surrounded by…
NASA’s Spitzer Space Telescope took this image of the California Nebula on January 25, 2020, five days before the spacecraft was decommissioned. The red and…
Artist’s conception of a brown dwarf and its magnetic field. The magnetic field, rooted deep in its interior, rotates at a different rate than the…
The path of a light beam is bent by the presence of mass, as explained by General Relativity. A massive body can therefore act like…
NASA’s Spitzer Space Telescope has concluded after more than 16 years of exploring the universe in infrared light. Credit: NASA/JPL-Caltech NASA’s Spitzer Space Telescope Ends…
Artist’s rendering of a “hot Jupiter” called KELT-9b, the hottest known exoplanet – so hot, a new paper finds, that even molecules in its atmosphere…
TOI 700, a planetary system 100 light-years away in the constellation Dorado, is home to TOI 700 d, the first Earth-size habitable-zone planet discovered by…
