Titan's chemical inventory is believed to bear some resemblance to the prebiotic soup on the early Earth.
On the surface of it, Earth and Saturn's moon Titan are wildly different from one another. Earth is temperate and warmed by the Sun, liquid water flows across its surface, and life pervades its opulent biosphere. Titan is beyond the reach of the Sun's warmth, is frigid and lifeless, and orbits a gas giant that is also lifeless.
Not even The People's Champion can save you from this Martian disaster.
An academic dives into "the other space race" as countries work to send satellites and other objects into orbit around the Earth.
Test your knowledge of NASA's triumphs, setbacks, and space-age breakthroughs that define this space agency's legendary history.
The Artemis 2 SLS rocket that will launch the next astronauts around the moon is all put together inside NASA's Vehicle Assembly Building.
JAXA has successfully deployed three new Cubesats from the International Space Station's Kibo module, marking another step in democratizing access to space.
In a surprise to researchers, the small, icy bodies beyond Pluto's orbit tend to rotate opposite the way they move around the Sun, which might say something about how they formed.
All sorts of crazy things have been suggested regarding 3I/ATLAS, the third known interstellar object that we’ve discovered. Some are simply conspiracy theories about it being an alien spacecraft, while others have been well-thought out suggestions, like using Martian-based probes to observe the comet as it streaked past the red planet. A new paper pre-published on arXiv and accepted for publication by the Research Notes of the American Astronomical Society by Samuel Grand and Geraint Jones, of the Finnish Meteorological Institute and ESA respectively, falls into the latter category, and suggests utilizing two spacecraft already en route to their separate destinations to potentially detect ions from the object’s spectacular tail that has formed as it approaches the Sun.
Better in-flight streaming and video-calling might just become more accessible thanks to a project supported by the European Space Agency (ESA). Building upon the success of an experiment for a new type of antenna terminal together with ESA, Viasat – a global leader in satellite communications – now plans to commercialise its new in-flight connectivity solution called Viasat Amara.
Reflect Orbital has applied for a Federal Communications Commission (FCC) license to launch a giant mirror to space next year.
Are you ready to take your first step into the space sector? The countdown has begun for the launch of the European Space Agency's 2026 Student Internship Programme, and you could be part of it. Applications open the first week of November.
The new Copernicus Sentinel-4 mission has delivered its first images, highlighting concentrations of atmospheric nitrogen dioxide, sulphur dioxide and ozone. Despite being preliminary, these images mark a major milestone in Europe’s ability to monitor air quality all the way from geostationary orbit, 36 000 kilometres above Earth.
Earth has a long, 4.5 billion history full of momentous twists and turns. Multiple prominent events played leading roles in Earth's story. One of them is the catastrophic impact with another planetesimal early in Earth's history that not only created the Moon, but altered Earth's chemistry forever.
A piece of smoldering wreckage found in Western Australia is likely part of a Chinese rocket that crashed to Earth on Saturday (Oct. 18), experts say.
SpaceX has long held the contract to land NASA's Artemis 3 astronauts on the moon a few years from now. But the agency plans to reopen the bidding, according to acting NASA chief Sean Duffy.
Dust devils are a regular occurrence on Mars. Similar to Earth, these short-lived whirlwinds emerge when surface heating occurs, causing changes in air pressure and a vertical column of wind to form. As the column pulls in surrounding air, it becomes a vortex that kicks up dust, which it carries with it across the surface. While Mars has a very thin atmosphere, less than 1% that of Earth's, the lower gravity means that its dust devils grow larger than anything we see here. And according to new research by an international research team, these dust devils will reach velocities that are higher than what we expected.
The wavelengths of radio light are so large that you can't capture a high-resolution image with a single dish. To capture an image as sharp as, say, the Hubble telescope, you'd need a radio dish tens of kilometers across. So radio astronomers took a different approach. They used an array of dozens of antennas, each capturing their own signal. Since the antennas not only capture precise data but also the precise timing of that data, astronomers can use a process known as interferometry. Light from a distant radio object reaches each antenna at a slightly different time, and by correlating the arrival times, astronomers can treat the array as a virtual antenna disk the size of the entire array. From many, one, as the saying goes.
The universe is a vast expanse, but within it, galaxies are not always solitary islands. Many exist in groups, with some being remarkably close to our own Milky Way. Understanding these nearby galactic neighbors provides invaluable insights into galactic evolution, interactions, and the larger structure of the cosmos.
NASA's Hubble Space Telescope captures the glittering spiral galaxy NGC 6951, where a central bar fuels a spectacular ring of newborn stars.
The discovery of a new array of molecules spouted from Enceladus indicates new promise for habitability within Saturn's frozen-over ocean.
