SpaceX's Starship megarocket aced its test flight today (Oct. 13), the 11th overall for the program and the final mission for this version of the giant vehicle.
SpaceX closed out a dramatic chapter in the development of its super-heavy-lift Starship launch system with a successful flight test that mostly followed the script for the previous flight test.
We talk to "Solar Opposites "executive producers Mike McMahan and Josh Bycel about the show's wild final season.
Precise measurements of stars’ motions show that a wave is propagating outward from our galaxy’s center — perhaps from a long-ago collision with another galaxy.
Ground-based telescopes have a fundamental problem that no amount of engineering can fix. They're trying to observe the universe through Earth's atmosphere, a constantly moving blanket of air that distorts and blurs incoming light. It's a little like trying to take a photograph of the bottom of a stream where the water is gently flowing! Space telescopes like Hubble easily sidestep this issue by operating above the atmosphere, but they can only photograph tiny slivers of sky. Now, researchers at Johns Hopkins University have developed a clever mathematical solution that could give ground based telescopes near space quality vision whilst retaining their ability to survey vast swathes of space!
The Taurid meteor streams have a reputation for generating impressive fireball meteors.
Hundreds of satellites may soon be flying in orbital regions that are already too packed to allow safe and long-term operations, a new study suggests.
The Great Oxidation Event, which occurred between 2.1 and 2.4 billion years ago, fundamentally transformed Earth's atmosphere and made complex life possible. Before this period, oxygen producing cyanobacteria had evolved hundreds of millions of years earlier, yet atmospheric oxygen levels remained low for an extended period. Scientists have long wondered over this delay, exploring various explanations from volcanic gases to microbial activity. A recent study from Okayama University in Japan offers a fresh view on this ancient mystery by examining two unlikely culprits, nickel and urea.
From how space rocks wobble to where to hit them, scientists are learning the fine art of asteroid deflection — and it could one day save Earth.
The Vezda might be vanquished, but there are more cosmic threats for Captain Pike and the Enterprise crew to confront in 2026.
New research suggests that this mystery platinum signature underneath the Greenland ice sheet may have originated from a volcanic fissure eruption in Iceland, not space.

After more than a week of launch delays, SpaceX is preparing to launch its Falcon 9 rocket from Cape Canaveral Space Force Station with two dozen of Amazon’s Project Kuiper broadband internet satellites onboard.
In 2030, the International Space Station will be deorbited: driven into a remote area of the Pacific Ocean.
Avoiding, or at least limiting the damage from, geomagnetic storms is one of the most compelling arguments for why we should pay attention to space. Strong solar storms can have an impact on everything from air traffic to farming, and we ignore them at our own peril and cost. Despite that threat, the tools that we have applied to tracking and analyzing them have been relatively primitive. Both simulations and the physical hardware devoted to it require an upgrade if we are to accurately assess the threat a solar storm poses. As a first step, a new paper from a group led by researchers at the University of Michigan created a much more detailed simulation that shows how important it is that we also have the appropriate sensing hardware in place to detect these storms as they happen.
If the universe is expanding, then what is it expanding into, and what is it expanding from? Where's the edge of the universe, and where is its center?
Centuries before the Roswell UFO Incident, Native Americans had their own stories to tell about alien visitations — for example, about the “Sky People” who traveled from the Pleiades star cluster to Earth and have a special bond with the Cherokee Nation.
The discovery of what is potentially the smallest clump of dark matter ever seen strengthens the case for cold dark matter.
We actually know very little about what's going on inside Uranus and Neptune, causing researchers to propose that these planets be called "rocky giants" instead.
The annual Orionid meteor shower comes to a peak on Oct. 20-21
The Vera C. Rubin Observatory's Simonyi Survey Telescope scans the heavens to start its decade-long exploration in the search for dark matter.
The isotopic ratio of sulfur-33 on the moon differs from that of Earth. Did the moon's sulfur instead come from the impactor that formed it?
