Total solar eclipse 2024: The moon"s moment in the sun
On April 8, 2024, much of North America will experience a solar eclipse: a cosmic alignment of sun, moon, and Earth, in that order. The moon's shadow path will make landfall on Mexico's Pacific coast, cross the United States from Texas to Maine, and.....»»
Webb peers into the tendrils of NGC 604
Two new images from the NASA/ESA/CSA James Webb Space Telescope's NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) showcase the star-forming region NGC 604, located in the Triangulum galaxy (M33), 2.73 million light-years away from Ea.....»»
Webb and Hubble telescopes affirm the universe"s expansion rate, but the puzzle persists
The rate at which the universe is expanding, known as the Hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of the cosmos......»»
Integrating non-additive GWAS with historical dissemination to illuminate nut traits and blooming time in almonds
Modern breeding focuses on genetic analyses and germplasm management and dominates in altering crop genomes, but often neglects non-additive genetic effects that are essential for understanding traits. Almond [Prunus dulcis Miller (D.A. Webb)] has si.....»»
"Baby quasars": James Webb Space Telescope spots little giants in the deep past
The James Webb Space Telescope has made one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant universe could change the way we understand the genesis of supermassive black holes......»»
Scientists use James Webb Space Telescope to uncover clues about Neptune"s evolution
A ring of icy rocks orbiting our sun just beyond Neptune may give us a glimpse of how Neptune—and other objects in the outskirts of our solar system—were formed......»»
See what James Webb and Hubble are observing right now with this tool
If you're looking for a relaxing way to observe the fascinating sights of space on your lunch break, then a newly updated tool from NASA has you covered......»»
Webb unlocks secrets of primeval galaxy
Looking deep into space and time, two teams using the NASA/ESA/CSA James Webb Space Telescope have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old......»»
Daily Telescope: A new Webb image reveals a cosmos full of galaxies

James Webb Space Telescope captures the end of planet formation
The James Webb Space Telescope (JWST) is helping scientists uncover how planets form by advancing understanding of their birthplaces and the circumstellar disks surrounding young stars......»»
What ended the "dark ages" in the early universe? New Webb data just brought us closer to solving the mystery
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......»»
Jaw-dropping Webb photo reveals how the universe turned its lights on
Scientists used the James Webb Space Telescope to view some of the earliest galaxies in the universe, revealing how these objects may have cleared cosmic gas and ended the Dark Ages. The universe was once stuck in the Dark Ages.It was time when.....»»
Scientists discover radiation from massive stars shapes planetary systems
How do planetary systems such as the solar system form? To find out, CNRS scientists taking part in an international research team studied a stellar nursery, the Orion Nebula, using the James Webb Space Telescope. By observing a protoplanetary disk n.....»»
Better neutron mirrors can reveal the inner secrets of matter
Improved neutron mirrors can increase the efficiency of material analysis in neutron sources such as the European Spallation Source. The improved mirror has been developed by researchers at Linköping University by coating a silicon plate with extrem.....»»
How molecular "handedness" emerged in early biology
Molecules often have a structural asymmetry called chirality, which means they can appear in alternative, mirror-image versions akin to the left and right versions of human hands. One of the great mysteries about the origins of life on Earth is that.....»»
Webb finds dwarf galaxies reionized the universe
Using the unprecedented capabilities of the NASA/ESA/CSA James Webb Space Telescope, an international team of scientists has obtained the first spectroscopic observations of the faintest galaxies during the first billion years of the universe. These.....»»
If exoplanets have lightning, it"ll complicate the search for life
Discovering exoplanets is almost routine now. We've found over 5,500 exoplanets, and the next step is to study their atmospheres and look for biosignatures. The James Webb Space Telescope is leading the way in that effort. But in some exoplanet atmos.....»»
