Matthew De Furio et al, Identification of a Turnover in the Initial Mass Function of a Young Stellar Cluster Down to 0.5 MJ, The Astrophysical Journal Letters (2025). DOI: 10.3847/2041-8213/adb96a. iopscience.iop.org/article/10. … 847/2041-8213/adb96a

Webb Reveals the Secrets of the Flame Nebula – Are These the Universe’s Smallest Stars?

This artist's concept shows what the isolated planetary-mass object SIMP 0136 could look like based on recent observations from NASA's James Webb Space Telescope and previous observations from Hubble, Spitzer, and numerous ground-based telescopes. Researchers used Webb's NIRSpec (Near-Infrared Spectrograph) and MIRI (Mid-Infrared Instrument) to measure subtle changes in the brightness of infrared light as the object completed two 2.4-hour rotations. By analyzing the change in brightness of different wavelengths over time, they were able to detect variability in cloud cover at different depths, temperature variations in the upper atmosphere, and changes in carbon chemistry as different sides of the object rotated in and out of view. This illustration is based on Webb's spectroscopic observations. Webb has not captured a direct image of the object. Credit: NASA, ESA, CSA, and Joseph Olmsted (STScI)

The Planet That Roams Alone: Webb’s Stunning Discovery of SIMP 0136’s Chaotic Atmosphere

This artist’s impression shows an example of a rogue planet with the Rho Ophiuchi cloud complex visible in the background. Rogue planets have masses comparable to those of the planets in our Solar System but do not orbit a star, instead roaming freely on their own. Image Credit: ESO/M. Kornmesser/S. Guisard

Beyond the Solar System: The Shocking Discovery of Free-Floating Planets

This artist’s concept visualizes a super-Neptune world orbiting a low-mass star near the center of our Milky Way galaxy. Scientists recently discovered such a system that may break the current record for fastest exoplanet system, traveling at least 1.2 million miles per hour, or 540 kilometers per second.
