NASA's James Webb Space Telescope is unveiling the secrets of the ‘cosmic web,’ offering new clues to galactic evolution

THE DEBRIEF - New data collected by NASA’s James Webb Space Telescope (JWST) is helping researchers map the cosmic web in the greatest detail ever achieved, providing new insights into the network of galaxies as improved resolution reveals hidden features. An international team of researchers led by the University of California, Riverside, revealed their newest...

Webb telescope's largest survey creates the most detailed map of the cosmic web ever made, tracing back over 13 billion years in time

EARTH.COM - For years, maps of how matter is arranged across the universe came with a built-in compromise. Individual galaxies showed up fine. The filaments and clusters they formed – the bigger architecture – remained smeared at the edges. The James Webb Space Telescope (JWST) is changing that. Its largest survey has produced the most...

Astronomers use the Webb telescope to improve our map of the cosmic web

ENGADGET - We love when astronomers share the images they capture with the James Webb Space Telescope because they are so dang beautiful and cool. But of course, science is about more than just pretty pictures. A research team has used the telescope to map out the cosmic web, a collection of dark matter, gas...

NASA’s James Webb telescope maps most detailed cosmic web across 13.7 billion years

INTERESTING ENGINEERING - Astronomers using NASA’s James Webb Space Telescope have created the most detailed map yet of the universe’s vast cosmic web, revealing how galaxies connected and evolved across 13.7 billion years of history. The new map gives scientists an unprecedented look at the large-scale structure of the universe during its earliest stages. Researchers...

3 puzzles of our universe could be solved with this new dark matter theory

SPACE.COM - A new type of self-interacting dark matter could provide solutions to three very different cosmic puzzles, new research suggests. The first mystery that could be solved involves an ultradense clump of matter detected in the system JVAS B1938+666, which is gravitationally lensed, or visibly distorted, thanks to a quirk of general relativity. The...

Is the earliest supermassive black hole mystery solved?

UNIVERSE TODAY - One of the most intriguing puzzles in cosmology is the existence of supermassive black holes that seem to appear very early in the history of the Universe. Astronomers keep finding them at times when, by all that they understand about the infant Universe, they shouldn't be there. The standard theory of black...

Astronomers reveal hidden lives of the early universe’s ultramassive galaxies

W.M. KECK OBSERVATORY - Maunakea, Hawaiʻi – An international team of astronomers has uncovered multiple evolutionary paths for the universe’s most massive galaxies. Observations of ultramassive galaxies, each containing more than 100 billion stars, show that less than two billion years after the Big Bang, some had already stopped forming stars and lost their dust...

FROnt Surface Type Irradiator, or FROSTI, will allow future detectors to run at higher laser powers, reducing noise and expanding capabilities

PHYSICS WORLD - Future versions of the Laser Interferometer Gravitational Wave Observatory (LIGO) will be able to run at much higher laser powers thanks to a sophisticated new system that compensates for temperature changes in optical components. Known as FROSTI (for FROnt Surface Type Irradiator) and developed by physicists at the University of California Riverside...

Laser wavefront-correcting device gives LIGO 10x boost to spot distant gravitational waves

INTERESTING ENGINEERING - Gravitational waves, tiny ripples in spacetime caused by cosmic collisions like merging black holes, are almost impossibly faint. Detecting them requires LIGO (Laser Interferometer Gravitational-Wave Observatory), one of the most sensitive instruments ever built. However, there’s a catch. To see farther and catch weaker signals, LIGO needs more powerful lasers, but stronger...

Dark matter could turn some planets into tiny black holes

SCIENCEALERT - Giant worlds beyond the Solar System could be the probe we need to figure out how dark matter manifests in the Universe. According to a new study, one particular dark matter model could see the mysterious mass accumulating in the cores of giant planets, collapsing into tiny black holes destined to consume the...
