SpaceX has postponed the planned tenth test flight of its Starship megarocket, citing a problem with ground systems that forced a halt to Sunday's countdown at Starbase in southern Texas. "Standing down from today's tenth flight of Starship to allow time to troubleshoot an issue with ground systems," the company posted on X. The giant rocket had been scheduled to lift off at 6:30 pm local

The world is set to heat up more than expected because of future changes in ozone, which shields Earth from ultraviolet radiation but also acts as a greenhouse gas. Although international bans on ozone-depleting chemicals such as CFCs have aided the layer's recovery, combined effects with air pollution mean ozone could add 40% more warming than earlier predictions suggested. A Univer

A SpaceX Falcon 9 rocket blasted into space on Thursday night carrying the US military's secretive X-37B drone. The rocket successfully launched at 11:50 pm (0350 GMT on Friday), according to SpaceX's livestream of the event. The Falcon 9 lit up the night sky over NASA's Kennedy Space Center, where it was launched from. The US Space Force has said the drone's mission will include

Space-based solar power could significantly reshape Europe's energy system by 2050, according to new research in the journal Joule. The study estimates the technology could reduce Europe's reliance on Earth-based wind and solar generation by up to 80% while lowering overall grid costs by 7% to 15%. Researchers modeled the European energy system in 2050 using two NASA-developed designs for

Dark energy, once thought constant across time, may instead evolve through the universe, according to new results from the Dark Energy Spectroscopic Instrument (DESI). Researchers show that interpreting black holes as dark energy bubbles not only supports this view but also offers consistent neutrino mass estimates. The DESI collaboration, working from Kitt Peak National Observatory in Ari

More than 5,000 planets have been discovered beyond our solar system, allowing scientists to explore planetary evolution and consider the possibility of extraterrestrial life. Now, a UC Riverside study published in Physical Review D suggests that these "exoplanets" could also serve as tools to investigate dark matter. The researchers examined how dark matter, which makes up 85% of the un

At 4:12 a.m. EDT on Aug. 7, mission controllers at Johns Hopkins Applied Physics Laboratory confirmed that New Horizons had safely entered hibernation mode. The spacecraft, operating more than 5.7 billion miles (9.2 billion kilometers) from Earth in the Kuiper Belt, acted on commands uploaded July 23. The confirmation signal required 8 hours and 31 minutes to reach Earth, traveling at light spee

The mystery at Jupiter's heart has taken a fresh twist - as new research suggests a giant impact may not have been responsible for the formation of its core. It had been thought that a colossal collision with an early planet containing half of Jupiter's core material could have mixed up the central region of the gas giant, enough to explain its interior today

A new Durham University study challenges the idea that Jupiter's unusual dilute core was formed by a giant collision, overturning a leading explanation of the planet's interior structure. Jupiter's core does not have a sharp boundary but gradually merges into its hydrogen-rich layers. This dilute core was first revealed by NASA's Juno spacecraft, sparking debate about how it formed.
