ESA’s state-of-the-art Biomass satellite launched aboard a Vega-C rocket from Europe’s Spaceport in Kourou, French Guiana. The rocket lifted off on 29 April 2025 at 11:15 CEST (06:15 local time).

At NASA’s Michoud Assembly Facility in New Orleans, the liquid hydrogen tank for the Artemis 3 Space Launch System rocket was moved into the factory's final assembly area on April 22, 2025.

What's this about five different alien creatures from five different worlds?

The U.S. Army launched its new hypersonic missile from Cape Canaveral Space Force station last week, just days after naming it the "Dark Eagle."

As the second-largest object in the main asteroid belt, Vesta attracts a healthy amount of scientific interest. While smaller asteroids in the belt are considered fragments of collisions, scientists think Vesta and the other three large objects in the belt are likely primordial and have survived for billions of years. They believe that Vesta was on its way to becoming a planet and that the Solar System's rocky planets likely began as protoplanets just like it. But new research is casting doubt on that conclusion.

Artificial intelligence could offer a powerful pathway to supercharge our ability to "hear" the universe, according to new research.

As scientists, we must not forget our collective direction: the pursuit of truths and our responsibility to share these truths — and only these truths — with humanity.

ESA’s groundbreaking Biomass satellite, designed to provide unprecedented insights into the world’s forests and their crucial role in Earth’s carbon cycle, has been launched. The satellite lifted off aboard a Vega-C rocket from Europe’s Spaceport in Kourou, French Guiana, on 29 April at 11:15 CEST (06:15 local time).

The crescent moon will seemingly jump over the planet Jupiter between the nights of April 29 and April 30.

Long-forgotten mine fields in Cambodia are being revealed in decades-old, recently declassified images from U.S. military satellites.

What will a human experience while standing on the surface of Saturn’s largest moon, Titan, even with the protection of a pressurized spacesuit? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as William O’Hara, who is the Executive Director of Explore Titan investigated what physical attributes a human will experience when standing on Titan’s surface. This study has the potential to help scientists, engineers, mission planners, and the public better understand the risks associated with sending humans to far-off worlds for long periods of time and how to develop technologies to mitigate these risks.

SpaceX sent another batch of Starlink satellites to orbit tonight (April 28), its second liftoff of the day.

Star birth is a process hidden inside dense crèches of gas and dust. Yet, if you know what to look for, you can see the products of this essential cosmic process across the sky. The Circinus West molecular cloud is a starbirth crèche some 2,500 light-years away. It boasts everything from dark nebulae to protostellar objects and newborn stars to the faint ghosts of stars that have already died.

How can walking robots deliver more efficient in-situ robotic exploration on the Moon compared to other types of robots? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers from the University of Southern California (USC) discussed the benefits of using legged robots for lunar exploration regarding gait speed (walking speed). This study has the potential to help engineers, scientists, mission planners, and astronauts develop novel robotic designs to conduct more efficient science and mission objectives on future Moon surface missions.

Update 11:05 p.m. EDT: SpaceX landed the first stage booster on the droneship.

A United Launch Alliance Atlas V rocket launched the first big batch of satellites for Amazon's Project Kuiper broadband constellation to low Earth orbit today (April 28).

Earth has a number of companions in space; of course the Moon is the most well known but there are a host of smaller objects that visit us, complete a few orbits then head off again. A team of astronomers have detected four objects like this and have performed spectroscopic analyses on them. They found that their surface composition is similar to eh Moon suggesting that it’s a major source of these temporary satellites instead of the asteroid belt.

The Orion Nebula is a fabulous example of a vast cloud of electrically charged gas which is emitting bright radiation. If the atoms in the gas are cool enough though, they can form giant molecular clouds that obscure light, these are known as dark nebula. A team of astronomers have now found an enormous cloud of molecular hydrogen in our own cosmic backyard just 300 light years away. The cloud contains 3,400 times the mass of the Sun and if we could see it, it would stretch nearly 40 times the width of the Moon across the sky.

The European Space Agency's Biomass forest-monitoring satellite will launch atop a Vega-C rocket early Tuesday morning (April 29), and you can watch the liftoff live.
