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.

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.
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.

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.

Our reliance on space infrastructure means that conflict in space would have global catastrophic consequences. But a recent declaration by the United States provides hope.
Scientists think there are 300 million habitable planets in the Milky Way, and some may be home to intelligent life.
