Twin Travelers In 1977, NASA launched twin spacecraft Voyager 1 and 2, taking advantage of a once-every-175-year planetary alignment of the four largest planets in our solar system: Jupiter, Saturn, Uranus, and Neptune. Using six gravity assists between them, this Grand Tour gave us up-close views of the gas and ice giants, including several moons. […]

October’s Night Sky Notes: Spooky Stargazing
The Ghoul Located within the constellation Perseus lies a star called Algol, also known as ‘Demon Star’ or ‘The Ghoul’. You can spot this star during the autumn months, along with Cassiopeia and Andromeda in the northeastern sky, beginning after 9 PM.

Bird constellations abound in the night sky, including Cygnus, the majestic swan. Easy to find with its dazzling stars, it is one of the few constellations that look like its namesake, and it is full of treasures. Visible in the Northern Hemisphere all summer long, there’s so much to see and even some things that […]
Celestial Wonders in Leo
Leo is a prominent sight for stargazers in April. Its famous sickle, punctuated by the bright star Regulus, draws many a beginning stargazer’s eyes, inviting deeper looks into some of Leo’s celestial delights, including a great double star and a famous galactic trio. Leo’s distinctive forward sickle, or “reverse question mark,” is easy to spot […]
Night Sky Network Celebrates Artemis II
Today, the crew of Artemis II reaches a milestone, traveling farther than any humans in recorded history, as they orbit the far side of the Moon, roughly 4,000 miles above the lunar surface. You can watch this historic broadcast on NASA’s YouTube channel today, April 6, 2026, at 10 AM Pacific (1 PM Eastern), or on NASA+. […]
Dim Delights in Cancer
Cancer the Crab is a dim constellation, yet it contains one of the most beautiful and easy-to-spot star clusters in our sky: the Beehive Cluster. Cancer also possesses one of the most studied exoplanets: the superhot super-Earth, 55 Cancri e. Find Cancer’s dim stars by looking in between the brighter neighboring constellations of Gemini and […]
Betelgeuse and the Crab Nebula: Stellar Death and Rebirth
What happens when a star dies? In 2019, Betelgeuse dimmed in brightness, sparking speculation that it may soon explode as a supernova. While it likely won’t explode quite yet, we can preview its fate by observing the nearby Crab Nebula. Betelgeuse is easy to find as the red-hued shoulder star of Orion. A variable star, […]
October’s Night Sky Notes: Let’s Go, LIGO!
by Kat Troche of the Astronomical Society of the Pacific September 2025 marks ten years since the first direct detection of gravitational waves as predicted by Albert Einstein’s 1916 theory of General Relativity. These invisible ripples in space were first directly detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO). Traveling at the speed of light […]
From City Lights to Moonlight: NASA Training Shows How Urban Parks Can Connect Communities with Space Science
When you think about national park and public land astronomy programs, you might picture remote locations far from city lights. But a recent NASA Earth to Sky training, funded by NASA’s Science Activation Program, challenges that assumption, demonstrating how urban parks, wildlife refuges, museums, and green spaces can be incredible venues for connecting communities with […]
Weird Ways to Observe the Moon
International Observe the Moon Night is on October 4, 2025, this year– but you can observe the Moon whenever it’s up, day or night! While binoculars and telescopes certainly reveal incredible details of our neighbor’s surface, bringing out dark seas, bright craters, and numerous odd fissures and cracks, these tools are not the only way to […]
