The moon and Saturn will be separated by about three degrees during a conjunction and close approach that occurs overnight on April 15.

As we get closer to the new moon, stargazing conditions will improve with the lack of natural light pollution.

On April 20, 2023, there will be a rare hybrid solar eclipse. Though you won't be able to see the eclipse from North America, you can still tune in to live streams.

UAE astronaut Sultan Al Neyadi is scheduled to become the first Arab astronaut to perform a spacewalk on April 28, 2023. Al Neyadi is aboard the International Space Station for a six-month mission.

NASA has announced its 2023 Phase 2 NIAC grantees, a group of six futuristic concepts that include a radio telescope array on the moon and a new form of planetary defense.

The interactive Global CTX Mosaic of Mars is the most detailed 3D map of Mars ever made. It was developed using 110,000 images taken by NASA's Mars Reconnaissance Orbiter.

Researchers have developed new AI-powered software that can sharpen astronomical images from ground-based telescopes that are blurred by Earth's atmosphere.

The Cosmic Seahorse galaxy is seen through a gravitational lens in a newly released image from the James Webb Space Telescope.

After dramatic budget cuts stalled NASA's VERITAS Venus mission, the nonprofit Planetary Society urges Congress for a revival.

A new AI-powered computer model is trained to predict when and where solar storms will strike Earth, giving us time to prepare infrastructure that could be impacted, such as the power grid.

The Hubble Space Telescope has imaged celestial object Z-229-15, which is simultaneously classified as a Seyfert galaxy, an active galactic nucleus (AGN), and a quasar.

This month's first quarter moon occurs today, March 28, meaning it will appear half-full in the night sky.

The meteoroid was traveling about 27,000 mph (43,452 kph) when it struck the atmosphere, exploding into smaller pieces — some of which hit the ground.

NASA's Mars Reconnaissance Orbiter photographed China's Zhurong rover in the same location for five months, indicating the rover has not yet awoken from hibernation.

On Wednesday (Feb. 22), the moon and Venus will make a close approach and also reach conjunction, which happens when they share the same right ascension.

The moon will be completely dark tonight as it enters the new moon phase of its 29.5-day cycle.

The James Webb Space Telescope spied the arms of barred spiral galaxy NGC 1433 teeming with young stars that are affecting the clouds of gas and dust around them.

Black holes may be the origin of dark energy, according to a study by a team of researchers led by the University of Hawaii.

The comet C/2022 A2 (Pan-STARRS) will reach perihelion, or the closest point to the sun in its orbit, on Saturday, Feb. 18. The comet will be visible from Earth at dawn and dusk.

The newfound exoplanet K2-415b is not within the habitable zone of its red dwarf host star, but it could have a neighbor that is.

Tonight the moon will reach its third-quarter phase, the last phase in the moon's monthly four-phase cycle. It will continue to wane until the new moon on Feb. 20.

We know precious little about how Mars got its atmosphere or how it disappeared. Now, thanks to some rocks from Duluth, Minnesota, scientists have a new theory.

Combining X-ray, radio, optical and infrared wavelengths, astronomers have imaged the messy collision of three galactic clusters leading to the formation of Abell 2256.

On Monday (Jan. 30), the moon will pass in front of Mars from the perspective of Earth in what's known as an occultation. The moon and Mars will also reach conjunction and appulse.

On Saturday, Jan. 28, skywatchers will be able to see the year's 1st first quarter moon, when the moon appears to be half-lit from the perspective of Earth.
