Every December, the night sky puts on a show that seasoned astronomers call the Super Bowl of meteor showers. The Geminids deliver up to 120 colorful meteors per hour under ideal conditions, with bright fireballs that can cast shadows on the ground. The combination of high meteor rates, vivid colors, reliable annual performance, and convenient … Read more
CRITICAL SAFETY WARNING: Never look at the sun directly or through a camera viewfinder without a certified solar filter. Pointing an unprotected camera at the sun can permanently damage your eyes and destroy your camera sensor in seconds. A solar filter rated to ISO 12312-2 is the minimum safety standard for both viewing and photography. … Read more
On August 12, , a total solar eclipse will sweep across the Arctic, Greenland, Iceland, and northern Spain, plunging a narrow corridor of Earth into daylight darkness for up to 2 minutes and 18 seconds. If you have ever wanted to stand in the moon’s shadow and watch the solar corona blaze in a twilight … Read more
A total lunar eclipse turns the Moon blood red through the same phenomenon that makes our sky blue and our sunsets red: a process called Rayleigh scattering, where Earth’s atmosphere scatters shorter blue wavelengths of sunlight while bending longer red wavelengths onto the lunar surface. When the full Moon passes completely into Earth’s shadow, direct … Read more
You can remove your eclipse glasses only during the brief window of totality, when the Moon completely blocks the Sun’s bright face, and only if you are inside the path of totality. During every other phase of a solar eclipse, even 99% coverage, looking at the Sun without certified eye protection can cause permanent retinal … Read more
Have you ever looked up at the night sky and noticed a bright object that seemed out of place among the familiar stars? That steady, unblinking light is almost certainly a planet, and unlike the fixed stars around it, that planet is slowly drifting across the sky night after night. Learning how to track a … Read more
Most people assume the full moon is the perfect moment to explore the lunar surface. It is the brightest, most dramatic, and most photographed phase we see in the night sky. But here is the counterintuitive truth that every experienced amateur astronomer knows: the full moon is actually the worst possible time to observe the … Read more
Every amateur astronomer remembers the first time they pointed a telescope at the Moon and felt underwhelmed. The surface looked flat, washed out, and nothing like the crater-rich images in magazines. The problem is almost never the telescope. It is the timing. Learning how to read the Moon’s terminator for the best crater views transforms … Read more
I still remember the first time I spotted the International Space Station. I was standing in my backyard on a cool evening, skeptical that I would actually see anything, when a brilliant white light rose over the horizon and glided silently across the sky. No flashing lights, no engine noise, just a steady glow moving … Read more
Looking up at a star-filled sky can feel overwhelming when you do not know where to start. I remember my first night trying to identify the brightest stars and constellations as a beginner, squinting at a star map, and feeling completely lost among thousands of pinpricks of light. The good news is that you do … Read more
