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 […]
Summer Triangle Corner: Altair
Altair is the last stop on our trip around the Summer Triangle! The last star in the asterism to rise for Northern Hemisphere observers before summer begins, brilliant Altair is high overhead at sunset at the end of the season in September. Altair might be the most unusual of the three stars of the Triangle, […]

Summer Triangle Corner: Vega
If you live in the Northern Hemisphere and look up during July evenings, you’ll see the brilliant star Vega shining overhead. Did you know that Vega is one of the most studied stars in our skies? As one of the brightest summer stars, Vega has fascinated astronomers for thousands of years.Vega is the brightest star in the […]
Explore Our Dynamic Sun!
from NASA’s Heliophysics Education Activation Team (NASA HEAT) and the Astronomical Society of the Pacific/Night Sky Network Have you ever wondered about what the Sun is made of? Or why do you get sunburned on even cloudy days? NASA’s new Explore the Sun toolkit brings the wonders of solar science to you, offering answers to […]
May’s Night Sky Notes: How Do We Find Exoplanets?
Astronomers have been trying to discover evidence that worlds exist around stars other than our Sun since the 19th century. By the mid-1990s, technology finally caught up with the desire for discovery and led to the first discovery of a planet orbiting another sun-like star, Pegasi 51b. Why did it take so long to discover these […]
