James Webb Space Telescope: A giant leap towards 'other Earths'?
Dec 10, 2021 (AFP)
But outside our own solar system, other stars give warmth and light to planets and, possibly, life. Soon to offer a better look at these so-called exoplanets is...
Atom laser creates reflective patterns similar to light
Dec 10, 2021 (SPX)
In experiments at Washington State University, scientists have developed a technique to see these matter wave caustics by placing attractive or repulsive obstac...
Simulated Webb Images of Quasar and Galaxy Surrounding Quasar
Dec 09, 2021 (SPX)
How is it possible that these quasars became so gigantic, with billions of solar masses, in the first 700 million years of the universe? Once you can see past t...
Astronomers find final missing piece of galaxy cluster collision puzzle
Dec 09, 2021 (SPX)
Most galaxies live in clusters: groups of hundreds or even thousands of galaxies. In between them is lots of space, filled up by a hot gas called the intraclust...
New technique reveals the age of massive Southern Cross star
Dec 09, 2021 (SPX)
With an entirely new approach, the team led by Dr Daniel Cotton, found the star to be 14.5 times as massive as the Sun and as young as 11 million years old, mak...
Transforming materials with light
Dec 09, 2021 (SPX)
"These tools could let you transform the electronic properties of materials at the flick of a light switch," says Caltech Professor of Physics David Hsieh. "But...
NASA Returns Hubble to Full Science Operations
Dec 08, 2021 (SPX)
The team will continue work on developing and testing changes to instrument software that would allow them to conduct science operations even if they encounter ...
Unique look at the self-destruction of a star is presented in 3D
Dec 08, 2021 (SPX)
The supernova that the researchers studied, known as SNR 0540-69.3, is a familiar subject. For those observing the remnants of exploded stars, it's one of the s...
Webb fuelled for launch
Dec 06, 2021 (ESA)
Webb's thrusters will use this propellant to make critical course-corrections after separation from Ariane 5, to maintain its prescribed orbit about one and a h...
Evidence emerges for dark-matter free galaxies
Dec 06, 2021 (SPX)
When Pavel Mancera Pina (University of Groningen and ASTRON, the Netherlands) and his colleagues discovered six galaxies with little to no dark matter, they wer...
Artificial material protects light states on smallest length scales
Dec 03, 2021 (SPX)
Scientists at Paderborn University have now demonstrated, for the very first time, the spatial confinement of a light wave to a point smaller than the wavelengt...
Molecular device turns infrared into visible light
Dec 03, 2021 (SPX)
At lower frequencies, the energy transported by light isn't enough to trigger photoreceptors in our eyes and in many other sensors, which is a problem given tha...
Beads of glass in meteorites help scientists piece together how solar system formed
Dec 03, 2021 (SPX)
Scientists with the University of Chicago have published an analysis laying out how these beads, which are found in many meteorites, came to be-and what they ca...
Light speed advances
Dec 03, 2021 (SPX)
That's precisely what Tingyi Gu is working on in the University of Delaware's Department of Electrical and Computer Engineering (ECE). But she's trying to contr...
Molding, patterning and driving liquids with light
Dec 01, 2021 (SPX)
The new method of molding and deforming water has potential applications in adaptive optics, mass transport and microfluidics manufacturing and molding of micro...
Arecibo data still has astronomers in a spin
Dec 01, 2021 (SPX)
Arecibo was the world's largest single-dish radio telescope until it was surpassed in 2016 by China's Five-hundred-meter Aperture Spherical Telescope (FAST). At...
Harris, Macron get first look at new James Webb images
Nov 30, 2021 (UPI)
Macron and Harris were given the first preview of II ZW 96, a merging of two galaxies about 500 million light years away from Earth. Images of II ZW 96 were cap...
NASA starts loading fuel for James Webb Space Telescope launch
Nov 29, 2021 (UPI)
Teams at the space center in French Guiana are loading 63 gallons of fuel and oxidizer into the $9.7 billion telescope, which is the largest and most powerful t...
Gaia reveals that most Milky Way companion galaxies are newcomers to our corner of space
Nov 26, 2021 (ESA)
A dwarf galaxy is a collection of between thousand and several billion stars. For decades it has been widely believed that the dwarf galaxies that surround the ...
Testing confirms Webb Telescope on track for targeted Dec 22 Launch
Nov 26, 2021 (SPX)
Additional testing was conducted this week to ensure the observatory's health following an incident that occurred when the release of a clamp band caused a vibr...
