Webb captures rarely seen prelude to a supernova
A Wolf-Rayet star is a rare prelude to the famous final act of a massive star: the supernova. As one of its first observations in 2022, the NASA/ESA/CSA James Webb Space Telescope captured the Wolf-Rayet star WR 124 in unprecedented detail. A distinc.....»»

Study tracks shifts in student mental health during college
A four-year study by Dartmouth researchers captures the most in-depth data yet on how college students' self-esteem and mental health fluctuates during their four years in academia, identifying key populations and stressors that the researchers say a.....»»
Webb finds ethanol and other icy ingredients for new worlds
An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered a variety of molecules, ranging from relatively simple ones like methane to complex compounds like acetic acid and ethanol, in early-stage protosta.....»»
Dark Energy Camera captures remains of a massive star that exploded nearly 11,000 years ago in huge gigapixel image
This colorful web of wispy gas filaments is the Vela Supernova Remnant, an expanding nebula of cosmic debris left over from a massive star that exploded about 11,000 years ago. Located around 800 light-years away in the constellation Vela (the Sails).....»»
Study: Conflicting values for Hubble Constant not due to measurement error

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......»»
Rare access to hammerhead shark embryos reveals secrets of its unique head development
Scientists very rarely get access to most sharks, the development of their young or the nursery grounds where they grow. So seeing a hammerhead shark (Sphyrna tiburo) embryo, halfway through its five-month development, is very unusual......»»
Mapping the future"s sweet spot for clean energy and biodiversity
Climate change is driving both the loss of biodiversity and the need for clean, renewable energy. It is also shifting where species are expected to live in the future. Yet these realities are rarely considered together. Where can clean energy project.....»»
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......»»

Study shows that the ATLAS detector can measure the flux of high-energy supernova neutrinos
High-energy neutrinos are extremely rare particles that have so far proved very difficult to detect. Fluxes of these rare particles were first detected by the IceCube Collaboration back in 2013......»»
James Webb Space Telescope captures the end of planet formation

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......»»
