Japan’s first H3 rocket, nearly a decade in development, was moments from liftoff Thursday (U.S. time) when the launch vehicle detected a problem and cut off the countdown just before sending a command to ignite two strap-on solid-fueled boosters.

A large European-built communications satellite owned by London-based Inmarsat is set to ride a SpaceX Falcon 9 rocket into orbit Friday night from Cape Canaveral, kicking off a mission to connect ships and airplanes across the Atlantic Ocean and the U.S. East Coast through 2040.
In this era of exoplanet discovery, astronomers have found over 5,000 confirmed exoplanets, with thousands more awaiting confirmation and many billions more waiting to be discovered. These exoplanets exist in a bewildering spectrum of sizes, compositions, orbital periods, and just about every other characteristic that can be measured.
How do you measure an object’s weight from a distance? You could guess at its distance and therefore derive its size. Maybe you could further speculate about its density, which would eventually lead to an estimated weight. But these are far from the exact empirical studies that astrophysicists would like to have when trying to understand the weight of stars. Now, for the first time ever, scientists have empirically discovered the weight of a distant single star, and they did so using gravitational lensing.
Virgin Galactic's carrier plane VMS Eve conducted a test flight on Wednesday (Feb. 15), taking to the skies for the first time since October 2021.
The three mysterious objects shot down recently by U.S. fighter jets were likely research or recreation objects lofted by private companies or academic institutions, President Joe Biden said.
As the successor to the venerable Hubble Space Telescope, one of the main duties of the James Webb Space Telescope has been to take deep-field images of iconic cosmic objects and structures. The JWST’s next-generation instruments and improved resolution provide breathtakingly detailed images, allowing astronomers to learn more about the cosmos and the laws that govern it. The latest JWST deep-field is of a region of space known as Abell 7244 – aka. Pandora’s Cluster – where three galaxy clusters are in the process of coming together to form a megacluster.
Black holes may be the origin of dark energy, according to a study by a team of researchers led by the University of Hawaii.
NASA-developed technology that can remotely detect the tiniest motions of the body caused by basic processes necessary for life will be used by disaster relief teams in earthquake-stricken Turkey.
The search for extraterrestrial intelligence should not exclude our own planet.
Melba Mouton worked during the era of "Hidden Figures" at NASA. The newly named Mons Mouton overlooks an area that will also be targeted by an ice-hunting rover in 2024 or so.
New research shows how a simple molecule called ortho-benzene helps form larger, more complex organic molecules at the core of frigid gas clouds in deep space.
The Goldilocks zone or habitable zone is the region around a star where an orbiting planet could host liquid water and, therefore, possibly support life.
Planetary defense refers to the effort to monitor and protect Earth from asteroids, comets and other objects in space.
The "Star Trek: Picard" Season 3 premiere is here and offers a trip down memory lane for anyone wishing for another season of "The Next Generation."
We put Sony's widest-angle APS-C lens to the test — was it worth the wait?
The Winchcombe meteorite was collected mere hours after it fell, but researchers have found that it was already contaminated with earthly minerals, including common table salt.
A meteorite believed to have originated from a brilliant fireball that lit up European skies on Monday (Feb. 13) was located in France by citizen scientists.
