The first JWST spectrum of the GRB 221009A afterglow
Gamma-ray bursts are the most energetic and luminous events known to occur in the Universe. Short-lived flashes of gamma rays that typically last from a a tenth of a second to less than an hour, gamma-ray bursts may for a brief period of time outshin.....»»
Scientists find 14 new transient objects in space by peering through the "Christmas Tree Galaxy Cluster"
An international team of scientists, led by University of Missouri's Haojing Yan, used NASA's James Webb Space Telescope (JWST) to discover 14 new transient objects during their time-lapse study of galaxy cluster MACS0416—located about 4.3 billion.....»»
Study shows willow bark extract has broad-spectrum antiviral effect
From a seasonal cold to a stomach bug, nobody likes catching a virus—and epidemics can be devastating. We need safe, sustainable antiviral options to treat the outbreaks of the future. Scientists in Finland have now shown that an extract of willow.....»»
Supermassive black holes shut down star formation during cosmic noon, says astronomer
Since it became operational almost two years ago, the James Webb Space Telescope (JWST) has produced countless breathtaking images of the universe and enabled fresh insights into how it evolved......»»
JWST detects carbon dioxide in a centaur for the first time
A study published Nov. 6 in The Planetary Science Journal examines how NASA's James Webb Space Telescope (JWST) has conducted a first-time detection of carbon dioxide in a centaur, this one designated 39P/Oterma. A centaur is a small planetary body t.....»»
Supermassive black hole found only half a billion years after Big Bang
There just isn't time for something that big to grow from a supernova remnant. Enlarge / Inset shows the JWST image of the galaxy in infrared, along with the X-rays from the black hole seen by the Chandra. While the X-ray source.....»»
Half of the mass of an early galaxy is in its central black hole
There just isn't time for something that big to grow from a supernova remnant. Enlarge / Inset shows the JWST image of the galaxy in infrared, along with the X-rays from the black hole seen by the Chandra. While the X-ray source.....»»
New Webb images show gas-rich baby galaxies setting the early universe alight
New images from the James Webb Space Telescope (JWST) have helped Australian astronomers unlock secrets of how infant galaxies started an explosion of star formation in the very early universe......»»
The JWST Has Spotted Giant Black Holes All Over the Early Universe
Giant black holes were supposed to be bit players in the early cosmic story. But James Webb Space Telescope observations are finding an unexpected abundance of the beasts......»»
JWST takes a detailed look at Jupiter"s moon Ganymede
Nature doesn't conform to our ideas of neatly-contained categories. Many things in nature blur the lines we try to draw around them. That's true of Jupiter's moon Ganymede, the largest moon in the solar system.....»»
Making high-quality crystals that resonate strongly with infrared light
Combining electronics with infrared light can enable small, fast, and sensitive devices for sensing, imaging, and signaling at the molecular level. However, in the infrared spectrum, materials must meet strict quality requirements for their crystals.....»»
New research sheds light on early galaxy formation
Researchers have developed a new computer simulation of the early universe that closely aligns with observations made by the James Webb Space Telescope (JWST)......»»
Astronomers want JWST to study the Milky Way core for hundreds of hours
To understand the universe, we need to understand the extreme processes that shape it and drive its evolution. Things like supermassive black holes (SMBHs,) supernovae, massive reservoirs of dense gas, and crowds of stars both on and off the main seq.....»»
JWST looks at the debris disk around a white dwarf
Debris disks are quite common in the universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around neutron stars. So what.....»»
Broad-spectrum antiviral candidate targets dengue and SARS-CoV-2
A broad-spectrum antiviral drug candidate, 2-thiouridine, that targets positive-strand RNA viruses has been identified and characterized......»»
Apple wins approval to use ultra-fast 6GHz band for Vision Pro, CarPlay, and more
The FCC in the US has officially given Apple, Meta, and Google the go-ahead to tap into the 6GHz band for wireless devices. This comes four years after the companies teamed up to petition the FCC for access to this spectrum, with one of the biggest u.....»»
Scientists present the first set of global maps showing geographic patterns of beta-diversity in flowering plants
Beta-diversity serves as a crucial metric for gauging shifts in species composition over spatial or temporal scales, bridging the spectrum between localized (alpha) and broader regional (gamma) diversity. In the fields of ecology, biogeography and co.....»»
Topdon TCView TC002 review: Disappointing take on a thermal camera
The Topdon TCView TC002 infrared camera promises to extend the iPhone's light-collecting capabilities by stretching into the infrared portion of the spectrum, but it's not a good choice.The Topdon TCView TC002 Review.Thermal cameras are priceless too.....»»
More JWST observations are finding fewer early massive galaxies
There's a common pattern in science. We develop some new process or tool that allows us to gather all kinds of data we've never had before, the data threatens to overturn all we've assumed about some long-established theory, and then the dust settles.....»»
Phonon engineering for extended lasing beyond the fluorescence spectrum
The electron and phonon are two fundamental particles (quasi-particles) of condensed matter and their interplay in single crystals can create many interesting physical phenomena, such as polaritons, charge density waves and up-conversion fluorescence.....»»
