Look east before dawn on Wednesday, Aug. 14, to see the giant planet and the Red Planet just a third of a degree from one another in a rare planetary conjunction.

Up to 75 'shooting stars' per hour may be visible in the night sky this evening as the annual Perseid meteor shower peaks on Monday (Aug. 12). The annual shower is linked to debris from Comet Swift-Tuttle.

This stunning image of dune fields near Mars' north polar ice cap, taken by NASA's Mars Reconnaissance Orbiter, showcases the impact of polar winds on the Red Planet's landscape.

A Hawaii telescope just captured a sun-like star's glowing gas layers as it expands. The resulting butterfly-shaped nebula is a sight to behold.

With its moonless sky, the first week of August is one of the best times all year to see the Milky Way and meteor showers without a telescope. Here's how to be in the right place at the right time for the best view.

The Hubble Space Telescope zooms in on a dense ball of millions of stars within a galaxy orbiting the Milky Way. Its ancient origins raise big questions about how galaxies form and grow.

Command module pilot Michael Collins took this iconic Apollo 11 photo 55 years ago today, after his historic trip around the far side of the moon made him "the world's loneliest man".

The Delta Aquariid meteor shower begins this week, bringing as many as 20 "shooting stars" per hour to the night sky. Here's why this year's shower offers ideal conditions for stargazers.

July's full moon — also known as the Buck Moon, the Thunder Moon and the Hay Moon — will be at its fullest on the night of July 21. It's the last "regular" full moon before a parade of four consecutive "supermoons" light up the sky.

Slovakian artist Martin Vargic's spectacular new infographics artistically portray, visualize and compare more than 1,600 planets in other star systems.

NASA's GOLD mission found unexpected X- and C-shaped structures in the plasma of Earth's ionosphere. Researchers have likened our upper atmosphere to "alphabet soup."

Summer is the best time to see the Milky Way in the Northern Hemisphere without a telescope. The key is to find clear, dark skies on moonless nights.

A new multiwavelength 3D visualization of the iconic "Pillars of Creation" showcases the differences between Hubble and James Webb Space Telescope data.

The sparkling galaxy NGC 1546 stars in Hubble's first new image since changing to its new "one-gyro mode," ending the telescope's roughly month-long break.

The "Blaze Star" T Coronae Borealis is expected to erupt with a magnificent explosion sometime between now and September, becoming visible to the naked eye. Here's how to find it when it does.

June's full "Strawberry Moon" rises one day after the summer solstice in the Northern Hemisphere. This will be the lowest full moon of the year.

The appearance this week of the three bright Summer Triangle stars — Vega, Deneb and Altair — marks the beginning of summer in the Northern Hemisphere. Here's how to spot them.

Snapped from lunar orbit in 1968 by NASA astronaut Bill Anders, who died this week at age 90, 'Earthrise' is perhaps the most iconic image of our planet ever taken.

Armed with the world's largest digital camera, the forthcoming Vera C. Rubin Observatory in Chile will take night-sky images that revolutionize astronomy.

A major lunar standstill is about to occur. The phenomenon happens every 18.6 years when the moon rises and sets at its most extreme points on the horizon, while also climbing to its highest and lowest point in the sky.

Images from the James Webb Space Telescope and the Chandra X-ray Observatory have been combined to reveal how the Crab Nebula's neutron star is changing.

The James Webb Space Telescope peers into NGC 4449, a small galaxy showing explosive star formation that astronomers can't quite explain.

The monster sunspot responsible for May's vibrant auroras will be facing Earth again in a matter of days, and it still appears to be active. Here's when to be alert for the next display of northern lights on the nights close to June's new moon.

The Juno spacecraft, which orbits Jupiter, has been imaging the giant planet's moon Europa and spotted apparent movement in its icy crust.
