How are liquid-fueled and solid-fueled missiles powered? What are the advantages and disadvantages of each, and how do military missiles differ from rockets used for spaceflight?

Ensuring women’s full participation across the AI field, especially in times of conflict and instability, is not just a matter of equality. It is essential for sound decision-making, and for the future of human knowledge.

No image is more closely identified with evolution than the familiar procession of figures that begins with an ape and ends with modern humans. What made it so successful – and why do biologists cringe at it?

Against the backdrop of intensifying competition in the race to the Moon, NASA has revised its Artemis plans—delaying the first crewed landing, adding missions, accelerating launch-rocket production, and dropping a planned upgrade.

Unusual geometric shapes, sophisticated designs, and advanced materials are only the visible layer of the physics and engineering that allow fighter jets to evade radar detection – and catch an enemy off guard on its own territory.

The crewed lunar mission slips to at least April, NASA names the astronaut behind an early ISS return, SpaceX sets more records, Rubin’s new alerts are poised to transform astronomy, and a lunar eclipse. This Week in Space

What makes a diamond sparkle, what makes it so hard, and what makes “forever” complicated—from deep inside the Earth to the science behind the sparkling gemstones

Another company has been approved for a private mission to the space station, astronauts are bringing smartphones, and a rule-breaking planetary system is turning expectations upside down. This Week in Space.

In a study conducted at CERN’s Large Hadron Collider, a symmetry breaking between matter and antimatter was observed.

A project led by Dr. Shay Monat at the International Space University has caught the attention of SpaceX CEO Elon Musk – and could mark an important step toward establishing a crewed base on the Moon.

Elon Musk is putting the Moon at the top of SpaceX’s priorities. China successfully tested its Moon-launch rocket, a new crew arrives at the ISS, and an especially far-southern solar eclipse. This Week in Space.

Sometimes physics struggles to provide clear answers to questions that seem simple. One of these questions is why ice is slippery. Although humans have been slipping on ice for many years, scientists still haven’t agreed on a single theory that fully explains why. A new study offers a potential answer.

Falcon 9 launches were suspended after a rare anomaly; SpaceX is merging and seeking approval to deploy one million satellites; an Israeli partnership with the International Space University, and a small victory for darkness. This Week in Space

Between creative freedom and smart manipulation, Roblox’s square characters hide a full-fledged economy, an intense social experience, and educational questions every parent needs to ask.

Why there is no contradiction between a warming global climate and the occurrence of extreme cold waves, such as the one currently affecting the United States.

A series of far-reaching steps by governments, research organizations, and even investment funds is expected to significantly expand the number of scientific publications freely accessible to the public.

The colorless, odorless gas kills thousands of people every year – especially during the cold season – and there is no effective antidote. How can carbon monoxide poisoning be prevented?

Most patients with the rare cancer neuroblastoma die within about five years – but one girl who received an experimental CAR-T treatment remains healthy 19 years later.

For the first time in more than half a century, humans will leave low Earth orbit and fly close to the Moon—without landing. Artemis II is meant to be the next step toward returning astronauts to the lunar surface, but major – and costly – challenges still lie ahead.

A veteran astronaut retires from NASA, a cracked spacecraft landed safely, a major military space-debris removal effort takes shape—and what’s the connection between solar eruptions and avalanches? Space News Roundup

Researchers have examined the bones of a seven-million-year-old ape and concluded that it walked on two legs. This new finding challenges earlier studies of the same fossils, which reached different conclusions.

An unprecedented wave of coral bleaching driven by warming oceans may signal that one of the world’s most important ecosystems has already reached a point of no return.

2025 was another record-breaking year, with more than 300 successful launches, breakthrough missions, and major advances in new rockets. A recap of 2025 in space.

In a first for the ISS era, NASA cut short Crew 11’s mission after a medical issue onboard. The four astronauts rode SpaceX’s Dragon back to Earth, splashing down safely off the California coast more than a month ahead of schedule.
