Skywatchers will get a rare opportunity to see Jupiter in its full glory when its opposition happens at the same time as its closest approach to Earth.

There is some debate as to the nature of the star cluster NGC1746.

Rapidly spinning dead stars in the dwarf galaxy Sagittarius are the source of gamma-ray emissions within the massive bubbles that blow out from our galaxy.

Scientists may have discovered when and how high-energy particles that bombard Earth emerge from violent environments, such as the sun's atmosphere.

Astronomers have spotted a hot spot orbiting Sagittarius A* that could be a gas bubble traveling at around 30% the speed of light.

Autumn arrives on Thursday (Sept. 22) with the autumnal equinox, but only in the Northern Hemisphere.

Massive volcanic eruptions may have played an important role in mass extinctions throughout history, including the one that killed the dinosaurs.

Located at the outer edge of the solar system Neptune has fascinated astronomers since its discovery. Now the James Webb Space Telescope has provided a stunning image of unrivaled detail.

On Wednesday morning, the moon will pass the Beehive cluster in the night sky, giving sky watchers an easy reference point to spot it.

By simulating the removal of craters left on the lunar surface by asteroid impacts, astronomers peered over 4 billion years back in time.

What's shaking on Mars? Thanks to the InSight lander scientists now know part of the answer is space rock impacts. The lander's seismometer has 'heard' at least four strikes.

The moon will pass by the brightest stars of the Gemini constellation  —  Pollux and Castor  —  and will be closest to the former early Tuesday morning.

The solar system's most massive planet, Jupiter, will make its closest approach to Earth for 59 years on Sept. 26 even as the gas giant will be directly opposite the sun as viewed from Earth.

The James Webb Space Telescope excels at capturing images of distant cosmic objects, but the telescope's new Mars images demonstrate it can have an impact much closer to home.

As the moon's light side recedes heading towards a new moon, it will be half-illuminated on Saturday during a phase called the last quarter.

Tropical Storm Fiona developed over the Atlantic Ocean on Wednesday (Sept. 14) and could eventually become a hurricane. Weather satellites are tracking the storm as it moves through the Caribbean.

A massive "hot DOG" galaxy is surrounded by a swarm of smaller galaxies that may be helping it grow to tremendous sizes.

Located at the outer edge of the solar system, the distant planet Neptune will make its closest approach to Earth on Friday, when it will be visible in opposition to the sun all through the night.

Skywatchers can watch as the moon blocks Uranus from view on Wednesday, Sept. 14 in an event called a lunar occultation.

Scientists have demonstrated that Einstein's theory of general relativity is correct to a remarkable degree of accuracy, despite having been around for more than a century.

Using the Keck Observatory astronomers have imaged the Orion nebula, an intense star-forming region close to Earth, in unprecedented detail.

The most massive planet in the solar system, Jupiter has played a key role in shaping the inner planets and its orbit could influence how habitable our planet is.

Strange hexagonal diamonds may have been jettisoned into space when a dwarf planet collided with a large asteroid around 4.5 billion years ago.

Jupiter-size worlds in stellar nurseries could be snatched from orbit around their home stars in 'planetary heists,' becoming what scientists have nicknamed 'BEASTies.'
