Listening for events like black hole collisions is important in astronomy research – and the technology is only getting better.
Private companies have launched dozens of imaging satellites – like the two small boxes in the middle of the photo – into orbit in recent years.
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.
Russia controls six modules aboard the International Space Station.

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.
A powerful enough laser beam could blind spy satellites.
Build a powerful enough laser, and you can shine it into space. Aim it well, and you can blind satellites.
VFTS 243 is a binary system of a large, hot blue star and a black hole orbiting each other, as seen in this animation.
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.
The sun at 13:32 on July 15, 2022, just as the filament that resulted in the solar flare begins to detach.
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.
This cluster of galaxies, called Stephan’s Quintet, is a composite image produced from two cameras aboard the James Webb Space Telescope.
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.
Satellite imagery monitors environmental changes to inform agricultural decisions. Agricultural patterns are distinctly visible in this near-vertical false colour infrared photography of farmland south of Khartoum, Sudan.
Technologies being developed for growing food in space have contributed to advances in agriculture and crops on Earth.
Women use energy in different ways to men.
My research shows how urban design can make it harder for women in some countries to make sustainable choices.
China and the U.S. both have big plans for the Moon, but there are a number of reasons why no country could actually claim ownership of any land there.

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.
The mirror on the James Webb Space Telescope is fully aligned and producing incredibly sharp images, like this test image of a star.

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 often looks enormous when it first rises because of what is known as the Moon illusion.
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.
Scientists expect the Voyager spacecraft to outlive Earth by at least a trillion years.
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.
The greenhouse at McMurdo Station in Antarctica is the only source of fresh food during winter.
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.
There is a U.S. flag on the Moon, but in the future, countries may start to turn access to the Moon and asteroids into serious wealth.

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.
