A company aiming to bring cell service to unmodified smartphones using a satellite network announced Thursday it had secured its ability to reach low Earth orbit.
Five varieties of heirloom seeds from the Choctaw Nation of Oklahoma were flown to the International Space Station last year and will be compared to Earth-bound seeds when planted this coming spring.
"At a time like this, we need to find more stories from the days when Americans outsmarted the bad guys and planted our flag on the moon."
RALEIGH, N.C. — Particle physicist Hitoshi Murayama admits that he used to worry about being known as the “most hated man” in his field of science. But the good news is that now he can joke about it.
We are all familiar with the atmosphere of the Earth and part of this, the ionosphere, is a layer of weakly ionized plasma. It extends from 50 to 1,500 km above the planet. It’s a diffuse layer but sufficient to interfere with satellite communications and navigation systems too. A team of researchers have come up with an intriguing idea to utilise millions of mobile phones to help map the ionosphere by relying on their GPS antennas.
Imagine a black hole with the mass of the asteroid Ceres. It would be no larger than a bacterium and practically undetectable. But if such black holes are common in the Universe, they would affect the motions of stars and galaxies, just as we observe. Perhaps they are the source of dark matter.
The final supermoon of 2024, the Beaver Moon of November, thrilled skywatchers around the world as it ushered in the weekend with a stunning night sky sight.
How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery" operating when the first stars appeared.
On Episode 137 of This Week In Space, Rod and Tariq talk with Jason Steffen, a member of the science team for the Kepler Space Telescope mission.
The dictionary defines "spacewoman" as simply "a woman astronaut." In the case of its latest usage, though, the term carries more meaning. "Spacewoman" is a new film about Eileen Collins.
The seasonal variations of methane in the Martian atmosphere is an intriguing clue that there might be life hiding under the surface of the red planet. But we won’t know for sure until we go digging for it.
The student-run USC Rocket Propulsion Lab's Aftershock II vehicle soared to an altitude of 470,400 feet last month, higher than any amateur rocket had ever gone before.
SpaceX has stacked its Starship megarocket ahead of the vehicle's sixth test flight, which is scheduled to take place on Tuesday (Nov. 19).
SpaceX is gearing up to launch its next Starship test flight, a mission that will attempt a second catch of the world's largest rocket on Nov. 19. Here's when to watch Starship Flight 6.
Blue Origin has announced the six crewmembers for NS-28, its next suborbital space tourism mission. Among them are 'Space Gal' Emily Calandrelli and two repeat customers.
For decades, astronomers have used powerful instruments to capture images of the cosmos in various wavelengths. This includes optical images, where visible light is observed, and images that capture non-visible radiation, ranging from the radio and infrared to the X-ray and Gamma-ray wavelengths. However, these two-dimensional images do not allow scientists to infer what the objects look like in three dimensions. Transforming these images into a 3D space could lead to a better understanding of the physics that drives our Universe.
Europe's Hera asteroid probe will use the Red Planet for a gravity assist on its way to scope out the space rock crash site of NASA's DART impactor.
"We think the water came from the melting of nearby sub-surface ice called permafrost, and that the permafrost melting was caused by magmatic activity that still occurs periodically on Mars to the present day."
Ever since William Herschel discovered Uranus in 1781, astronomers have been eager to find new planets on the outer edge of the solar system. But after the discovery of Neptune in 1846, we’ve found no other large planets. Sure, we discovered Pluto and other dwarf planets beyond it, but nothing Earth-sized or larger. If there is some planet nine, or “Planet X” lurking out there, we have yet to find it.
A stellar odd couple 700 light-years away is creating a chaotically beautiful display of colourful, gaseous filaments. The Hubble captured the pair, named R Aquarii, and their symbiotic interactions. Every 44 years the system’s violent eruptions blast out filaments of gas at over 1.6 million kilometers per hour.
Crew-8 commander Matthew Dominick says NASA is carefully making decisions for astronaut safety while the ISS deals with a leak, and spacesuit issues, related to aging hardware.
