Astronomers using the James Webb Space Telescope have determined that stars in early galaxies transformed the gas throughout the universe from opaque to transparent.

Using data from NASA's Juno spacecraft, an international team has correlated the variations in Jupiter's bands to changes in the planet's magnetic field.

The moon and Mars will dance together in the night sky both tonight (May 23) and Wednesday night (May 24).

Tonight (May 19) is the new moon, and it's a rare "black moon," which occurs approximately once every 33 months.

A new study has determined the most likely origin of one repeating fast radio burst to be a dense object — potentially a neutron star — with a binary companion.

The sun fired a huge cloud of plasma directly at Earth on Sunday evening (May 7), an outburst that could boost auroras in the next day or so.

Four crewmembers will live in a 1,700-square-foot 3D-printed habitat at NASA's Johnson Space Center in a simulation of a Mars mission.

Dwarf planet Haumea reaches both opposition and perigee on April 20, making this a prime opportunity to see the dwarf planet in the night sky.

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.
