A planet in a triple-star system has been discovered.
Publicly available data and collaborations between scientists have led to the discovery of a planet in a triple-star system.
Where do the hydrogen and oxygen that make up the earth’s water come from?
A recent study shows that the Earth's water could come directly from the oxygen and hydrogen present in the rocks that formed it, and not from a late supply by asteroids.

On Dec. 21, Jupiter and Saturn will be so close together they will almost appear to be touching.
From the birth of Jesus Christ to Newton's discovery of gravity, great conjunctions of Jupiter and Saturn have many notable connections in human history.

A severe climate change event on Venus may have transformed an Earth-like climate to the current uninhabitable-to-humans state.

New mathematical technique enables astronomers to predict the whereabouts of missing worlds around nearby stars.

COVID-19 may have messed up school and shut down a lot of entertainment venues. But you can still brighten things up by doing a little stargazing at night, an astronomer says.
Unlike Earth’s atmosphere, Jupiter’s ‘sky’ hosts magnificent shades of orange, white, brown and blue.
Atmospheres can be all different colours, depending on what's in them.
Saturn is one of a few planets in our solar system surrounded by rings.

We're not sure how the rings work or how they formed, but there are a few theories.

Why isn't there an endless variety of planets in the universe? An astrophysicist explains why planets only come in two flavors.

On June 5-6, 2012, NASA’s Solar Dynamics Observatory collected images of one of the rarest predictable solar events: the transit of Venus across the face of the Sun.
This hot, acidic neighbor with its surface veiled in thick clouds hasn't benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
When it was young, the Sun spun fast – very fast. It would do one rotation in a just one or two Earth days.
Yes, the Sun absolutely spins. In fact, everything in the universe spins. Some things spin faster than the Sun, some are slower and some things spin 'backwards'.

Astronomers have found the first observational evidence for a disc of material around a giant young planet at a distant star. It's a place they think moons can form.
Searching for planets around nearby stars is like searching for a needle in a field of haystacks.
Science is full of surprises. While searching for planets orbiting nearby stars, researchers stumbled across the remains of a star that once outshone the Sun.

When you look up at the vastness of space you can see hundreds, thousands and even millions of years into the past.
Nobody knows for sure - but it’s possible.
There are probably more than a million planets in the universe for every single grain of sand on Earth. That's a lot of planets. My guess is that there probably is life elsewhere in the Universe.
Once people get there, Mars will be contaminated with Earth life.

NASA's InSight Mars lander touches down Nov. 26, part of a careful robotic approach to exploring the red planet. But human exploration of Mars will inevitably introduce Earth life. Are you OK with that?

There are lots of places where it's much, much hotter than the Sun. And the amazing thing is that this heat also makes new atoms - tiny particles that have made their way long ago from stars to us.
