Analyses of its emissions using NASA’s Neil Gehrels Swift Observatory indicate that the interstellar comet probably has a very different structure than comets in the solar system.
Previously undetected organic compounds have been found in ice ejected into space from Enceladus, making the satellite a prime candidate for further research.
Old rocket parts and decommissioned satellites are whizzing around in low Earth orbit, where they risk colliding with the ever-growing constellations of modern satellites being launched.
The gravitational lensing that causes this rare phenomenon cannot be explained solely by looking at observable objects—suggesting that dark matter had a hand in its formation.
The Amazon founder’s space company will transport NASA's VIPER rover to the lunar south pole—if it proves capable of delivering a payload to the moon in an upcoming mission.
From lava worlds to gas giants, NASA says the variety of these worlds is staggering—and that signs of a further 8,000 distant planets are awaiting confirmation.
A sci-fi idea is gaining supporters, from billionaires to city councils. Whether it’s feasible is another matter.
Analysis by researchers at the University of Bern suggests that water and other volatile compounds arrived on Earth from outer space—specifically via a collision with a Mars-sized planet billions of years ago.
Orbital missions will unlock the next phase of Starship’s development, providing better data on the performance of the spacecraft’s heat shield and allowing for tests of in-orbit refuelling, which will be essential for missions to Mars.
The workhorse rocket has continued its streak of success.
