How NASA"s Roman Telescope will measure the ages of stars
Guessing your age might be a popular carnival game, but for astronomers it's a real challenge to determine the ages of stars. Once a star like our sun has settled into steady nuclear fusion, or the mature phase of its life, it changes little for bill.....»»
Improved spin and density correlation simulations give researchers clearer insights on neutron stars
When a star dies in a supernova, one possible outcome is for the remains to become a neutron star. Inside a neutron star, the protons and electrons combine into uncharged neutrons. This substance is called neutron matter......»»
An improved quantification of the intergalactic medium and cosmic filaments
Much of the mass in the universe lies not in stars or galaxies, but in the space between them, known as the intergalactic medium. It is warm and even hot, and is called the "warm-hot intergalactic medium," or WHIM. It holds about 50% of the normal ma.....»»
Webb observations explore the Westerlund 1 star cluster
An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a supermassive Galactic open cluster known as Westerlund 1. Results of the observational campaign, presented in a paper published Nov. 20 on the arXiv.....»»

Final data and undiscovered images from NASA"s NEOWISE
While NASA's NEOWISE telescope ended its journey through space on Nov. 1, 2024, the team at IPAC, a science center at Caltech, was working on one further gift from the prolific mission......»»
Bandwidth measurements show how pulsar signals distort as they move through space
A study that sheds new light on how pulsar signals—the spinning remnants of massive stars—distort as they travel through space, published in The Astrophysical Journal, was led by Dr. Sofia Sheikh, SETI Institute researcher, and performed by a mul.....»»
Scientists enhance Seaglider technology to measure carbon dioxide
Scientists around the world rely on ocean monitoring tools to measure the effects of climate change. Researchers at the University of Alaska Fairbanks and their industry partners have advanced the technology available to measure carbon dioxide in the.....»»
NASA satellite data reveal role of green spaces in cooling cities
As any urban dweller who has lived through a heat wave knows, a shady tree can make all the difference. But what happens when there's no shade available?.....»»
NASA awards SpaceX a contract for one of the few things it hasn’t done yet
This was the first time ULA's Vulcan rocket was eligible to compete for a major NASA contract. When you compare SpaceX to the world's other space enterprises, it's probably easier.....»»

SpaceX to launch NASA’s Dragonfly drone mission to Titan
In 2028, a NASA mission called Dragonfly will launch using a SpaceX Falcon Heavy on a trip to Saturn's moon Titan......»»
Sombrero Galaxy dazzles in new Webb images and video
A new mid-infrared image from the NASA/ESA/CSA James Webb Space Telescope features the Sombrero galaxy, also known as Messier 104 (M104). The signature, glowing core seen in visible-light images does not shine, and instead a smooth inner disk is reve.....»»
Europa Clipper: Millions of miles down, instruments deploying
NASA's Europa Clipper, which launched Oct. 14 on a journey to Jupiter's moon Europa, is already 13 million miles (20 million kilometers) from Earth. Two science instruments have deployed hardware that will remain at attention, extending out from the.....»»
Astronomers measure cosmic electrons at the highest energies to date
Five telescopes of the H.E.S.S.-collaboration in Namibia are used to study cosmic radiation, especially gamma radiation. With data from 10 years of observations, researchers have now been able to detect cosmic electrons and positrons with an unpreced.....»»
The early universe may have had giant batteries of dust
The largest magnetic fields in the universe may have found themselves charged up when the first stars began to shine, according to new research......»»
WEAVE spectrograph uncovers dual nature of galaxy shock
Using the set of first-light observations from the new William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE) wide-field spectrograph, a team of more than 50 astronomers, led by Dr. Marina Arnaudova at the University of Hertfordshire, has.....»»
Satellite data and algorithms reveal which ships emit excessive nitrogen
Ships are still emitting too much nitrogen oxide. Until now, it has been impossible to measure this at sea, but that is set to change. Solomiia Kurchaba combined satellite data and developed algorithms to identify which ships are emitting too much. K.....»»
Space station crew had an amazing stroke of luck during Starship launch
The ISS crew happened to find itself directly above SpaceX's Starship launch on Tuesday, and that meant only one thing for NASA astronaut Don Pettit......»»
Video: Our sun is the star in a new simulation
NASA supercomputers are shedding light on what causes some of the sun's most complex behaviors. Using data from the suite of active sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar d.....»»
