Webb’s mirror alignment is done, now it’s on to the instruments
The mirror is now working with all five instruments, and limited only by physics. Enlarge / A very detailed view of one of the Milky Way's satellite galaxies. (credit: NASA/STScI) In mid-March, NASA released an image from the.....»»
Making ultra-fast electron measurements in multiple directions to reveal the secrets of the aurora
The energetic electrons that drive the aurora borealis (the northern lights) have a rich and very dynamic structure that we currently do not fully understand. Much of what we know about these electrons comes from instruments that have fundamental lim.....»»
Out of alignment: How clashing policies make for terrible environmental outcomes
Policy alignment sounds dry. But think of it like this: you want to make suburbs cooler and more liveable, so you plant large trees. But then you find the trees run afoul of fire and safety provisions, and they're cut down......»»
James Webb images capture the galactic winds of newborn stars
A stunning new pair of images from the James Webb Space Telescope show a new view of a familiar galaxy: Messier 82......»»
Revolutionizing spectrometry with ultra-simplicity: Disrupting conventional designs through novel diffraction computing
Spectrometers are crucial scientific instruments in various research fields and have consistently served as indispensable tools for foundational research. However, the unwieldy size of conventional spectrometers poses challenges for cost-effective an.....»»
JWST observations explore molecular outflows of a nearby merging galaxy
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby merging galaxy known as NGC 3256. Results of the observational campaign, presented March 21 on the pre-print server arXiv, yield essential informa.....»»
Euclid space telescope’s vision cleared thanks to deicing
The Euclid Space Telescope is fully operational after a deicing procedure removed small amounts of water ice from its mirror......»»
Astronomers conduct first search for forming planets with James Webb Space Telescope
Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly. Although several dozens of such disks have been imaged, just two planets have been caught in the act of forming so far......»»
NASA selects first lunar instruments for Artemis astronaut deployment
NASA has chosen the first science instruments designed for astronauts to deploy on the surface of the moon during Artemis III. Once installed near the lunar South Pole, the three instruments will collect valuable scientific data about the lunar envir.....»»
New NASA software simulates science missions for observing terrestrial freshwater
From radar instruments smaller than a shoebox to radiometers the size of a milk carton, there are more tools available to scientists today for observing complex Earth systems than ever before. But this abundance of available sensors creates its own u.....»»
Stunning James Webb images show birth and death of massive stars
The James Webb Space Telescope continues to surprise us with stunning pictures, but of what exactly? Astronomer Nienke van der Marel shows with three images how massive stars lead short but explosive lives......»»
Research team proposes a novel type of acoustic crystal with smooth, continuous changes in elastic properties
In dim light a cat sees much better than you do, as do dogs and nocturnal animals. That's because the structure of a cat's eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye that is not focused by the.....»»
Astronomers explore stellar populations of an extremely metal-poor dwarf galaxy
Using the James Webb Space Telescope, astronomers have conducted near- and mid-infrared observations of an extremely metal-poor blue compact dwarf galaxy known as I Zwicky 18. Results of the observational campaign, presented in a paper published Marc.....»»
NASA, industry improve lidars for exploration, science
NASA engineers will test a suite of new laser technologies from an aircraft this summer for Earth science remote sensing. Called "lidar," the instruments could also be used to improve models of the moon's shape and aid the search for Artemis landing.....»»
Webb finds hints of a third planet at PDS 70
The exoplanet census now stands at 5,599 confirmed discoveries in 4,163 star systems, with another 10,157 candidates awaiting confirmation. So far, the vast majority of these have been detected using indirect methods, including transit photometry (74.....»»
JWST observations shed more light on the nature of a distant galaxy cluster
Astronomers from the Nanjing University in China and elsewhere have performed high-resolution observations of a distant galaxy cluster known as CL J1001+0220 using the James Webb Space Telescope (JWST). The observational campaign, described in a pape.....»»
How to Fix AirPlay Issues
AirPlay, the feature that allows iPhone, iPad, and Mac users to stream or mirror content on the Apple TV or a smart TV, is fantastic when it works properly. Unfortunately, sometimes it doesn’t. We often see complaints about AirPlay problems, co.....»»
