OneWeb working with Arianespace, who owes the satellite internet firm six more Soyuz launches, to find rides to orbit for more than 200 of its spacecraft left grounded by an embargo on Western payloads flying aboard Russian rockets.
Astronomers have watched the young binary star system SVS 13 for decades. Astronomers don’t know much about how planets form around proto-binary stars like SVS 13, and the earliest stages are especially mysterious. A new study based on three decades of research reveals three potentially planet-forming disks around the binary star.
Geopolitical tensions won't keep an American astronaut and two Russian cosmonauts from returning to Earth together as planned this month, NASA says.
Starship, self-landing rockets and a Tesla-driving mannequin are part of the package.
In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll start drifting away from your friends after reading today’s today: open clusters!
If dark matter is out there, and it certainly seems to be, then what could it possibly be? That is perhaps the biggest mystery of dark matter. The only known particles that match the requirement of having mass and not interacting strongly with light are neutrinos. But neutrinos have low mass and zip through the cosmos at nearly the speed of light. They are a form of “hot” dark matter, so they don’t match the observed data that require dark matter to be “cold.” With neutrinos ruled out, cosmologists look toward various hypothetical particles we haven’t discovered, and perhaps the most popular of these are known as axions.
AAS Nova reports on a "super-puff" exoplanet that's nearly 15 times less dense than Jupiter.
The "Saturday Night Live" star and five other people are scheduled to fly to suborbital space aboard Blue Origin's New Shepard vehicle on March 23.
One of Earth's two mysterious mantle blobs is much higher than the other, raising questions about its impact on Earth's surface.
The Russian invasion of Ukraine could have serious consequences for those organizations pursuing scientific endeavors.

Astra engineers identified two problems — an electrical design issue and a software glitch — that prevented a rocket from reaching orbit last month with a suite of NASA-sponsored CubeSats, clearing the way for a return-to-flight mission that could launch from Alaska as soon as Monday.
The private spaceflight startup Astra will launch a commercial mission for Spaceflight, Inc. today and you can watch it live online.
SpaceX has launched about 150 missions in its first 20 years. Here's a look at 20 of the most important and memorable of them.
Reusing rockets and dreaming big are some of the things that have made SpaceX stand out.
Asteroid samples collected during the Hayabusa mission have helped scientists better model potential impacts of near-Earth objects.
An Earthbound experiment is replicating the extreme heat found in galaxy clusters located in deep space using nearly 200 lasers.
Sometimes in space, even when you’re millions of kilometers from anything, you’re still being watched. Or at least that’s the case for the Parker Solar Probe, which completed the 11th perihelion of its 24 perihelion journey on February 25th. While the probe was speeding past the Sun, it was being watched by over 40 space and ground-based telescopes.
This will likely come as a surprise to no one who has closely watched the development of NASA’s next giant rocket, the Space Launch System (SLS), but it’s going to be expensive to use. Like, really expensive – to the tune of $4.1 billion per launch, according to the NASA Inspector General. That’s over double the original expected launch cost.
The first teaser trailer for the next live-action "Star Trek" spinoff, "Star Trek: Strange New Worlds," has beamed in from Paramount Plus.
You can watch a big asteroid make a safe flyby of Earth today (March 11) from any spot with good internet access.
The planets in our solar system come in two forms: Some are rocky, and some are gaseous. But all of the moons in our solar system are rocky, even the ones that orbit gas giants. So why aren't some moons in the solar system made of gas? And are there gaseous moons anywhere in the universe?
