SpaceX is preparing to launch its latest batch of 24 Starlink V2 Mini satellites into a polar, low Earth orbit on Wednesday.
Newly released images of the supermassive black hole at the heart of the galaxy M87 show that the plasma that swirls around it has unexpectedly reversed directions.
The updated and non-VR version of the latest first-person Alien video game is spreading to all current-gen platforms.
Humanity can establish a self-sustaining settlement on Mars in the next 30 years, provided our heavy-lift launch technology advances as planned, SpaceX chief Elon Musk said.
We rate the Orzorz as the best viral star projector on the market and it's now under $50 before Amazon's Prime Day in October offers are live.
A spectacular partial solar eclipse will be visible across a swathe of the southern hemisphere this week.
The 1,115-foot-wide (340 meters) asteroid Apophis will pass closer to Earth than many satellites fly in April 2029, giving scientists and stargazers a rare front-row seat.
Astronomers say that mysterious interstellar visitors like 'Oumuamua and 3I/ATLAS are the most common large bodies in the Milky Way — and our best chance to study other planetary systems.
Even though they're far from home, astronauts on the International Space Station still have normal routines, including getting regular haircuts.
In this quiz, you'll match iconic sci-fi monsters to the books that birthed them—and the authors who dared to imagine the unimaginable.
Scientists created the most accurate three-dimensional map of star-formation regions in our Milky Way galaxy, based on data from the European Space Agency’s Gaia space telescope. This map will teach us more about these obscure cloudy areas, and the hot young stars that shape them.
With a modest amount of thrust and power, a new ion engine system could get rid of 1-ton pieces of space junk in less than 100 days. Here's how it works.
A surge of asteroids might have peppered the inner solar system some 800 million years ago, in a short-lived shower that left its mark — literally — on Earth and its neighbors.
Former NASA deputy chief and shuttle commander Pam Melroy has joined Venus Aerospace's board after its groundbreaking RDRE flight, bringing her decades of experience to help scale the startup's propulsion technology.
What are the constants of nature? What do they do? What do they tell us…and what do they not tell us?
Scientists at The University of Texas at Austin have discovered that volcanic activity on Mars between 3 and 4 billion years ago likely released unusual forms of sulphur gases that could have trapped heat and maintained liquid water on the planet's surface. This finding, published in Science Advances, offers a fresh perspective on how Mars might have supported early life.
On July 1st, 2025, astronomers at NASA's Asteroid Terrestrial-impact Last Alert System (ALERT) detected the third interstellar object (ISO) to enter our Solar System - 3I/ATLAS. Shortly thereafter, an international team led by researchers from Michigan State University (MSU) published the first scientific paper detailing the early scientific findings on this ISO. Hundreds of hours of observations have since been dedicated to measuring the astrometry, photometry, rotation period, and spectroscopy of this object to determine its trajectory, composition, and where it came from.
Deep in space, an ancient brown dwarf nicknamed "The Accident" has revealed the first-ever detection of a molecule that scientists have been searching for in planetary atmospheres for decades. This discovery not only explains why silicon remains hidden in Jupiter and Saturn's atmospheres, but also opens a window into how the chemistry of our universe has evolved over billions of years, showing us that sometimes the most unexpected finds yield the greatest scientific breakthroughs.
Science is a story of coming up with theories then doing our best to disprove them. That is especially true for theories on a grand, cosmological scale, though disproving them can be particularly hard. One of the most famous examples of a hard to disprove theory is that of dark energy and dark matter. In large parts of space we see unequivocal evidence that something is messing with general relativity. But down at the scale of our own solar system, there’s no evidence of it whatsoever, at least as far as we can see. A new paper from Slava Turyshev, a physicist at NASA’s Jet Propulsion Laboratory, discusses a way scientists might be able to deal with this discrepancy - by being very, very selective with the way we test for evidence of dark matter and energy in our solar system.
Comet 3I/ATLAS's appearance in the inner Solar System in July 2025 triggered a wave of interest. Not only in the comet itself, but in interstellar objects (ISO) in general. So far we only know of three ISOs, and it's only natural to wonder about their origins, and how common they are. But scientists, being naturally curious, have other questions, too. What would happen if an ISO was captured by a young solar system?
The period known as "Cosmic Noon," which took place roughly 2 to 3 billion years after the Big Bang, was characterized by the rapid formation of new stars and planetary systems. Naturally, objects dated to this period are coveted by scientists hoping to learn more about the processes that led to the formation of planets and the emergence of life itself. This includes asteroids and comets, which are known to be composed of material leftover from the formation of entire star systems and their planets. And with the detection of three interstellar objects (ISOs) in the Solar System since 2017, there could be multiple opportunities to do so.
