Private satellite companies have boomed in recent years, and many experts have wondered what role they would play in a conflict. They have proved to be invaluable to Ukraine in recent months.
As far as we know, only one person has ever been directly struck by space debris. That was back in 1997.
The head of the Russian space agency announced that the country will withdraw from the International Space Station after 2024. A space policy expert explains what this means and why it’s happening now.
Build a powerful enough laser, and you can shine it into space. Aim it well, and you can blind satellites.
Astronomers have discovered the first dormant black hole outside of the Milky Way. These black holes are not absorbing matter from a nearby star, making them incredibly hard to find.
The unusual planetary system has a host star orbited by two giants. One has an incredible odd route around its star. And the other (unlike our own gas giants) is hellishly hot.
NASA, NOAA and SpaceWeather say a coronal mass ejection will reach Earth this week. It has the potential to knock out communications in some parts of the world.
NASA released five new images from the James Webb Space Telescope, revealing incredible details of ancient galaxies, stars and the presence of water in the atmosphere of a distant planet.
Technologies being developed for growing food in space have contributed to advances in agriculture and crops on Earth.
My research shows how urban design can make it harder for women in some countries to make sustainable choices.
A comment by Bill Nelson, the NASA administrator, sparked a strong public response from the Chinese government. But due to legal and practical reasons, no country could take over the Moon anytime soon.
It’s the oldest light in the universe.
It has taken eight months to test and calibrate all of the instruments and modes of the James Webb Space Telescope. A scientist on the team explains what it took to get Webb up and running.
The Moon illusion is what makes the Moon look giant when you see it rising over a distant horizon. An astronomer explains what causes this awe-inspiring trick of the mind.
A professor of religion and science explains different views on immortality, from the religious perspective of President Jimmy Carter to the scientific, secular take of Carl Sagan.
Scientists just grew plants in soil from the Moon, but Antarctica has long provided researchers with the perfect place to test their agricultural techniques for a future in space.
There’s a lot of technological progress required before off-Earth mining operations can be considered feasible.
Current trends suggest that powerful nations are defining the rules of resource use in space and satellite access in ways that will make it hard for developing nations to ever catch up.
The pulsar PSR J0523-7125 is more than ten times brighter than any other radio pulsar outside the Milky Way.
