C/2022 E3 (ZTF) hasn't been this close to Earth in 50,000 years since the last Ice Age and prior to the extinction of the Neanderthals.

A forthcoming telescope that will observe Earth from space has been renamed in honor of George R. Carruthers, a visionary scientist who designed and built a telescope placed on the moon.

A spectacular new image shows the Soul Nebula infused with red light, highlighting a tadpole-like dense region of gas.

On Saturday (Jan. 28), the moon will cover Uranus in the night sky during a lunar occultation for some regions of Earth. In other places, the two bodies will share a close approach to one another.

Astronomers may finally know what delivers the gas that feeds the powerful phenomena surrounding active black holes.

After 31 years in orbit, NASA's magnetosphere-studying mission Geotail has come to end after the spacecraft's final data recorder failed.

A new model for dark matter suggests an early universe phase transition and candidate particles known as HYPERs could finally shed light on this mysterious matter.

On Wednesday (Jan. 25) the moon will meet up with Jupiter in the night sky as the two bodies share the same right ascension and make a close approach to each other.

Material collected by the Perseverance rover will be handled at the Mars Sample Receiving Project office at NASA's Johnson Space Center in Houston.

Solar activity increased on Jan. 13 as massive active regions of the sun rounded its east limb to face Earth.

On Sunday (Jan. 22), the planets Saturn and Venus will make a close approach to each other in the night sky, separated by no more than the width of a finger.

Scientists have returned from Antarctica with an impressive haul of meteorites, including a near-17-pound monster.

The conjunction of Venus and Saturn will be livestreamed so astronomy fans can watch it from the comfort of their homes without having to brave the bitter cold of a January evening.

Astronomers have detected a radio signal from the most distant galaxy yet. The special radio wavelength could indicate that scientists are ready to investigate how stars formed in the early universe.

The annual Ursae Minorid meteor shower which began on Jan. 15 peaks on Thursday, Jan. 19, with the meteors best seen when the constellation Ursa Minor is high above the horizon.

A new survey of the Milky Way's galactic plane has revealed an incredible 3.32 billion cosmic objects, including towering gas clouds and billions of stars.

Three newly discovered ultra-faint dwarf galaxies could offer clues to the conditions in the early universe and to the nature of dark matter.

NASA has released satellite view showing California's brutally wet start to the new year.

When solar winds bombard Earth's magnetosphere, they create waves that shouldn't be able to traverse a turbulent region called the shock. New research demonstrates how this appears to happen.

The face of the moon will be half-illuminated once again on Saturday (Jan. 14) as the moon enters its last quarter phase heading to the next new moon and the start of the next lunar cycle.

A distant black hole has a real sweet tooth, stretching a star that ventured too close to it into a stellar taffy and a doughnut the size of the solar system before devouring it.

As solar activity ramps up, two giant active regions of the sun are moving to face Earth, bringing with them an increased possibility of violent space weather.
