The United Arab Emirates' Hope Probe, on a wide orbit around Mars, provides views of the dynamic Red Planet.

The discovery of the first quadruple asteroid system raises the question: Is there a limit to how many moons an asteroid can have?

We’re drawn to the night sky for different reasons. Wonder. Joy. Discovery. And sometimes, for relief.

Astronomers combined forces to confirm that a black hole proposed to lie a mere 1,000 light-years away isn’t really there.

Evenings see a crescent Moon join Sirius, the brightest start (other than the Sun) in northern skies. For planets, look to the dawn.

The daily rising and setting of Earth's shadow is a beautiful sight anyone on the planet can view. It's also an opportunity to witness the rapid changes that accompany sunset or sunrise, but at the opposite end of the sky.

Astronomers have imaged the magnetic field along which gas flows to a galaxy's central black hole.

Whether you’re just getting started in astronomy or simply looking to do some casual sky-watching, our monthly Sky Tour astronomy podcast provides an informative and entertaining 12-minute guided tour of the nighttime sky. Download the March episode to find and learn about Sirius, the brightest star in the night sky.

Astronomers have discovered a pair of supermassive black holes that whirl around each other every two years.

As the winter Milky Way rides high, open star clusters near and far, and from compact to sparse, await your binoculars or telescope, At dawn catch the Venus-Mars pair, and try for the closer Mercury-Saturn pair lower down.

Astronomers have found a black hole leaning decidedly askew in its orbit with a star.

Astronomers have found a fast radio burst — presumably a flash from a young stellar remnant — amongst the ancient stars of a globular cluster, challenging ideas about what produces these enigmatic flashes.

A visible glow from our sister planet’s nightside sheds new light on a 300-year-old observing enigma dubbed the “ashen light.”

How are stars born? One of the best places to test ideas about stellar birth is in Orion.

With the Moon gone from the evening sky, trace out Monoceros the Unicorn walking behind Orion. Spot the famous binocular star clusters at his eye and horn-tip, and don't miss M41 under Sirius. Meanwhile, the waning Moon, passes Venus, Mars and Mercury at dawn.

With the Moon departing the evening sky, now's a good time for a closer look at the northern winter Milky Way and its southern summer counterpart, too. No equipment required!
