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.....»»
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.....»»
NASA is stacking the Artemis II rocket, implying a simple heat shield fix
NASA expects it to take about four months to fully assemble the main parts of the SLS rocket. The Space Launch System rocket that will dispatch four astronauts on the first Moon m.....»»
Are fast radio bursts caused by interstellar objects crashing into neutron stars?
Every now and then, astronomers will detect an odd kind of radio signal. So powerful it can outshine a galaxy, but lasting only milliseconds. They are known as fast radio bursts (FRBs). When they were first discovered a couple of decades ago, we had.....»»
Astronomers take first close-up picture of a star outside our galaxy
Located a staggering 160,000 light-years from us, the star WOH G64 was imaged thanks to the impressive sharpness offered by the European Southern Observatory's Very Large Telescope Interferometer (ESO's VLTI). The new observations reveal a star puffi.....»»
As NASA increasingly relies on commercial space, there are some troubling signs
"The government's really got to look at itself." When it comes to space policy, a hallmark of the first Trump administration was its embrace of private companies. NASA sought to b.....»»
NASA ocean world explorers have to swim before they can fly
When NASA's Europa Clipper reaches its destination in 2030, the spacecraft will prepare to aim an array of powerful science instruments toward Jupiter's moon Europa during 49 flybys, looking for signs that the ocean beneath the moon's icy crust could.....»»
Chandra and Hubble tune into "flame-throwing" Guitar Nebula
Normally found only in heavy metal bands or certain post-apocalyptic films, a "flame-throwing guitar" has now been spotted moving through space. Astronomers have captured movies of this extreme cosmic object using NASA's Chandra X-ray Observatory and.....»»
NASA"s Swift reaches 20th anniversary in improved pointing mode
After two decades in space, NASA's Neil Gehrels Swift Observatory is performing better than ever thanks to a new operational strategy implemented earlier this year. The spacecraft has made great scientific strides in the years since scientists dreame.....»»
Making Mars"s moons: Supercomputers offer "disruptive" new explanation
A NASA study using a series of supercomputer simulations reveals a potential new solution to a longstanding Martian mystery: How did Mars get its moons? The first step, the findings say, may have involved the destruction of an asteroid......»»
Minecraft Movie trailer explores the origins of Steve
Where "anything you can imagine is possible—as long as what you imagine can be built out of blocks." Jack Black stars as Steve in A Minecraft Movie......»»
Dedicated Roman gladiator superfans were the football hooligans of their day
In the amphitheater of Gladiator II, Ridley Scott trains his lens on fighters and emperors—but no account of ancient gladiators is complete without its devotees......»»
From Houston to the moon: Johnson"s thermal vacuum chamber tests lunar solar technology
Imagine designing technology that can survive on the moon for up to a decade, providing a continuous energy supply. NASA selected three companies to develop such systems, aimed at providing a power source at the moon's South Pole for Artemis missions.....»»
Automated 3D computer vision model offers a new tool to measure and understand dairy cow behavior and welfare
Dairy cows typically rest for 10 or more hours a day, so a dry, clean, and comfortable place—such as a freestall—to lie down and rest is essential for their health, well-being, and production performance. One key factor in whether stalls are comf.....»»
Predicting the next supernova explosion: New simulations reveal the physics of supernova shock breakout
Stars with masses between 10 and 30 times that of the sun, in their final evolutionary stages, form an iron core that ultimately collapses into a neutron star. This collapse releases a tremendous amount of gravitational potential energy through neutr.....»»
The space station just had to pull a maneuver to avoid space debris
The space station had to undergo another repositioning maneuver to move it out of the way of approaching space debris, NASA announced......»»

First pairs of white dwarf–main sequence binaries discovered in clusters shine new light on stellar evolution
Astronomers at the University of Toronto (U of T) have discovered the first pairs of white dwarf and main sequence stars—"dead" remnants and "living" stars—in young star clusters. Described in a new study published in The Astrophysical Journal, t.....»»
Here’s what NASA plans to do with its shiny new SpaceX spacecraft
NASA has big plans for its two new lunar spacecraft, currently under development by SpaceX and Blue Origin......»»
Hollywood techniques help NASA visualize supercomputing data
Captivating images and videos can bring data to life. NASA's Scientific Visualization Studio (SVS) produces visualizations, animations, and images to help scientists tell stories of their research and make science more approachable and engaging......»»
New giant radio galaxy discovered with MeerKAT
An international team of astronomers has employed the MeerKAT radio telescope to investigate giant radio galaxies in the field of the Cosmological Evolution Survey (COSMOS). They found a new giant radio galaxy that had not been reported before. The f.....»»
