Water was Already Here Before the Earth Formed
Where did Earth’s water come from? That’s one of the most compelling questions in the ongoing effort to understand life’s emergence. Earth’s inner solar system location was too hot for water to condense onto the primordial Earth. The prevailing view is that asteroids and comets brought water to Earth from regions of the Solar System beyond the frost line.
How Galaxies Can (Rarely) Lose Their Dark Matter
A careful study of cosmological simulations shows that dark matter–less galaxies aren't impossible — just really rare.
Billionaire's 'Polaris Program' to set space records on SpaceX Dragon, Starship
The billionaire commander of the first "all-civilian" space mission has now filed a new flight plan, underwriting a series of three SpaceX launches to rapidly advance human spaceflight capabilities.
Moon group pushes for protection of ultraquiet lunar far side
A newly established group called the Moon Farside Protection Permanent Committee has begun framing issues and solutions to guard against RFI corruption of the moon's far side.
'Star Trek: Discovery' season 4, episode 8 review: A not-awful installment for its TV return
It's not terrible; it's just not as good as it could've been. And it could've been really good
Billionaire plans three more flights with SpaceX, culminating in Starship mission

Jared Isaacman, the billionaire businessman who bankrolled the first human space mission with all private citizens last year, announced plans Monday for up to three more SpaceX flights, a privately-funded program that will include the first commercial spacewalk, and ultimately a ride on the giant Starship rocket ship.
Inventing the future of Navigation
Video: 00:05:15
Many of the experts that designed and oversaw the Galileo satnav system are now supporting cutting-edge European companies in the development of new navigation technologies and services. The result is ESA’s Navigation Innovation and Support Programme, NAVISP.
NAVISP is looking into all kinds of clever ideas about the future of navigation: ways to improve satellite navigation, alternative positioning systems and, new navigation services and applications. Working in partnership with European industry and researchers, more than 200 NAVISP projects have been initiated so far.
NAVISP is divided into three elements, the first looking into improving and expanding satellite navigation, as well as establishing novel ‘positioning, navigation and timing’ (PNT) services. NAVISP’s second element focuses on innovation for competitiveness, developing all kinds of new PNT products and services. Its third element covers support to Member State priorities, including support for national testbeds and programmes.
Astronomy Jargon 101: Hubble’s Law
In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll expand your horizons with today’s topic: Hubble’s Law!
In 1929 astronomer Edwin Hubble made a remarkable measurement. Earlier in that decade, he had discovered that the Andromeda Nebula was not a nebula at all, but an entirely different galaxy completely separated from the Milky Way by millions of light-years of cold, hard nothing. He then expanded that initial discovery and began compiling a catalog of galaxies and their distances from us.
The singular pull of black holes in games
As mysterious as they are dangerous, black holes in games allow us to reach the unreachable and teach us something along the way.
Watch Russia launch a fresh cargo ship to the International Space Station today
A new Russian cargo ship will blast off Monday (Feb. 14) with tons of supplies and equipment for the Expedition 66 crew. Here's how you can watch it live.
'Invisible' earthquake caused mysterious 2021 tsunami, scientists find
Scientists argue that we need to build better monitoring systems to spot earthquakes of this type.
Want to use the James Webb Space Telescope? Here's how scientists book time with the giant observatory.
The hottest commodity in astronomy these days is time — specifically, time using NASA's brand-new, ultra-powerful observatory.

An Indian radar satellite and two rideshare payloads rode a Polar Satellite Launch Vehicle into orbit Sunday, returning India’s space program to flight after the failure of a different type of rocket last August.
The out-of-control rocket about to hit the moon is not a SpaceX Falcon 9, astronomers now say: report
A rocket set to hit the moon March 4 might not be from SpaceX after all, astronomers now say. It may be a Chinese rocket stage.
Musk Shows how They’re Planning to Catch SuperHeavy Boosters
SpaceX’s entire business model is based on the reusability of its rockets. That business model has proven viable time and time again as boosters continue to land safely only to be reused later. But as the rockets they’re using get bigger and bigger, the harder and harder it will get for them to land directly on the ground, as models they’ve completed so far have. So for its SuperHeavy Booster, designed to launch its Starship craft into orbit, SpaceX has to develop a new way of capturing the rockets without damaging them. Its head, Elon Musk, has shared a Twitter video showing how it will do just that.

Astronomy Jargon 101: Heliosphere
In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll push the boundaries with today’s topic: the heliosphere!
If you want a handy definition of what’s “inside” the solar system, then the heliosphere is your best bet. This is a region dominated by particles constantly emanating from the Sun, and the Sun’s own magnetic field. This region extends out to millions of kilometers, well past the orbit of Pluto.
What would a Super Bowl on Mars look like? Spacesuits and lower gravity for sure (video)
In a new video from NBCLX, United Launch Alliance CEO Tory Bruno and NBC sports producer Brad Fosler explain what Super Bowl LVI would look like on Mars.
Moon-crashing SpaceX rocket will create new crater – here's what we should worry about
It’s not often that the sudden appearance of a new impact crater on the Moon can be predicted, but it’s going to happen on March 4, when a derelict SpaceX Falcon 9 rocket will crash into it.
