How Long Does It Take to Make a Planet? Webb’s Latest Discovery Extends the Cosmic Clock

March 6, 2025
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)

WD 2226-210 and the Helix Nebula (Labeled). In about 5 billion years, our sun will run out of fuel and expand, possibly engulfing Earth. These end stages of a star’s life can be utterly beautiful as is the case with this planetary nebula called the Helix Nebula. Credit: X-ray: NASA/CXC/SAO/Univ Mexico/S.

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 impression shows two tiny but very dense neutron stars at the point at which they merge and explode as a kilonova. Such a very rare event is expected to produce both gravitational waves and a short gamma-ray burst, both of which were observed on 17 August 2017 by LIGO–Virgo and Fermi/INTEGRAL respectively. Subsequent detailed observations with many ESO telescopes confirmed that this object, seen in the galaxy NGC 4993 about 130 million light-years from the Earth, is indeed a kilonova. Such objects are the main source of very heavy chemical elements, such as gold and platinum, in the Universe.
