About 400,000 years after the Big Bang, the cosmos was a very dark place. The glow of the universe’s explosive birth had cooled, and space was filled with dense gas — mostly hydrogen — with no sources of light. Slowly, over hundreds of millions of years, the gas was drawn into clumps by gravity, and ...
Like a shiny, round ornament ready to be placed in the perfect spot on a holiday tree, supernova remnant Cassiopeia A (Cas A) gleams in a new image from NASA’s James Webb Space Telescope. As part of the 2023 Holidays at the White House, First Lady of the United States Dr. Jill Biden debuted the first-ever ...
It is no exaggeration to say the James Webb Space Telescope (JWST) represents a new era for modern astronomy. Launched on December 25 last year and fully operational since July, the telescope offers glimpses of the universe that were inaccessible to us before. Like the Hubble Space Telescope, the Webb telescope is in space, so ...
The first images of a nebula from the James Webb Space Telescope gave astronomers remarkable insights into the death of the star that created these beautiful haloes of gas and dust. Among the first five image sets from the James Webb Space Telescope (JWST) released in July were a set of remarkably detailed photographs of the Southern Ring Nebula, ...
An international team of astronomers has used data from NASA’s James Webb Space Telescope to report the discovery of the earliest galaxies confirmed to date. The light from these galaxies has taken more than 13.4 billion years to reach us, as these galaxies date back to less than 400 million years after the Big Bang ...
NASA’s space telescope has produced a molecular and chemical portrait of the atmospheric constituents of exoplanet WASP-39 b, a Saturn-sized behemoth that orbits a star some 700 light-years away. The observations provide a full menu of atoms and molecules, and even signs of active chemistry and clouds. The suit of discoveries is detailed in a ...
A recent study, entirely done by researchers at the Instituto de Astrofísica de Canarias (IAC) has produced the most complete analysis to date of the intracluster light, the diffuse and faint light emitted by stars in galaxy clusters that are not gravitationally bound to any galaxy. This result was based on data obtained by the ...
The observatory’s Mid-Infrared Instrument (MIRI) provides a different view of the famous Pillars of Creation, revealing young stars that have not yet cast off their dusty “cloaks.” This is not an ethereal landscape of time-forgotten tombs. Nor are these soot-tinged fingers reaching out. These pillars, flush with gas and dust, enshroud stars that are slowly ...
NASA’s James Webb Space Telescope (JWST) is revealing the universe with spectacular, unprecedented clarity. The observatory’s ultrasharp infrared vision has cut through the cosmic dust to illuminate some of the earliest structures in the universe, along with previously obscured stellar nurseries and spinning galaxies lying hundreds of millions of light-years away. In addition to seeing ...
The latest images of Jupiter from the James Webb Space Telescope (JWST) are stunners. Captured on July 27, the infrared images — artificially colored to make specific features stand out — show fine filigree along the edges of the colored bands and around the Great Red Spot and also provide an unprecedented view of the ...
