Webb locates dust reservoirs in two supernovae
Supernovae, the explosive deaths of stars, are some of the universe's biggest bursts of energy and light. When they erupt, one supernova can shine even brighter than an entire galaxy......»»
Double-peaked supernovae offer clues to pre-supernova outbursts
New research helps in understanding the evolution and final stages of massive stars, the role of binary interactions, and the mechanisms behind mass loss, which ultimately affect the properties of the resulting supernova and its remnant. This work al.....»»
Wildfires Are Contaminating Water Supplies
Wildfires don’t just destroy forest—they can increase sediment in rivers and reservoirs, spark algae blooms, and pollute watercourses with dangerous chemicals, leaving water providers to grapple with long-term consequences......»»
Webb discovers six new "rogue worlds" that provide clues to star formation
Rogue planets, or free-floating planetary-mass objects (FFPMOs), are planet-sized objects that either formed in interstellar space or were part of a planetary system before gravitational perturbations kicked them out......»»
Image: Saharan dust in the wind
The Suomi NPP satellite acquired this image of a plume of Saharan dust as winds lofted it over the Atlantic Ocean on Aug. 24, 2024......»»
James Webb is explaining the puzzle of some of the earliest galaxies
Webb has been causing bafflement in the field of cosmology. But the problem isn't that the universe is broken - it's that early black holes were playing tricks......»»
In six new rogue worlds, Webb Telescope finds more star birth clues
The James Webb Space Telescope has spotted six likely rogue worlds—objects with planetlike masses but untethered from any star's gravity—including the lightest ever identified with a dusty disk around it......»»
Novel features of r-process nucleosynthesis shed light on origin of heavy elements
In a study published in The Astrophysical Journal, scientists have proposed the features of the rapid neutron capture process (r-process) nucleosynthesis in a novel scenario: common envelop jet supernovae (CEJSNe). The study sheds new light on the or.....»»
Carbon emissions from forest soil will likely grow with rising temperatures
The soils of northern forests are key reservoirs that help keep the carbon dioxide that trees inhale and use for photosynthesis from making it back into the atmosphere. But a unique experiment led by Peter Reich of the University of Michigan is showi.....»»
US water reservoirs are shrinking and becoming less reliable, new study finds
Major water reservoirs across the continental United States are experiencing longer, more severe, and more variable periods of low storage than several decades ago, a new study reports. The problems are most severe in the western and central United S.....»»
Astronomers explore the nature of galaxy NGC 891 with JWST
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby spiral galaxy known as NGC 891. Results of the observational campaign, published August 15 on the preprint server arXiv, provide more insights int.....»»
Extraterrestrial chemistry with earthbound possibilities
Who are we? Why are we here? As the Crosby, Stills, Nash & Young song suggests, we are stardust, the result of chemistry occurring throughout vast clouds of interstellar gas and dust. To better understand how that chemistry could create prebiotic mol.....»»
Is the Google Pixel 9 waterproof?
The Google Pixel 9 series is dust and water resistant, but not waterproof. The two terms are mistakenly used interchangeably, but here's what all that means......»»
New analysis of Webb data measures universe expansion rate, finds there may not be a "Hubble tension"
We know many things about our universe, but astronomers are still debating exactly how fast it is expanding. In fact, over the past two decades, two major ways to measure this number—known as the "Hubble constant" —have come up with different ans.....»»
Research team finds evidence of hydration on the asteroid Psyche
Using data from NASA's James Webb Space Telescope, a Southwest Research Institute-led team has confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche. The presence of hydrated minerals suggests a complex history for Psyche, impor.....»»
Novel anemometer tracks sound travel for speedier, more precise wind speed calculations on Mars
Mars has a notoriously inhospitable environment, with temperatures that fluctuate dramatically over the course of a Martian day and average minus 80 degrees Fahrenheit. Its surface is mostly covered in red dust, with terrain typified by craters, cany.....»»
Webb captures new image of gassy baby stars
NASA's James Webb Space Telescope has captured a phenomenon for the very first time. The bright red streaks at top left of this June 20, 2024, image are aligned protostar outflows—jets of gas from newborn stars that all slant in the same direction......»»
James Webb Telescope captures gorgeous galaxy with a hungry monster at its heart
A new image from the James Webb Space Telescope shows off a nearby galaxy called Messier 106......»»
Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. However, a very small amou.....»»
Decades of PC building advice was just overturned
The 80 Plus certification has been the marker of a quality power supply for decades, but it's slowly biting the dust......»»
