A daily update by email. Science news, great photos, sky alerts.
An earthly lion guards the gates, while, in the sky, a celestial Lion - Leo - ascends. Astrophotographer Jeff Dai of China tells the story.
Jeff Dai created this moontrail photo by keeping his camera still, rather than tracking along with the stars. He said it was about a 3-hour exposure.
There's a nova in the sky now. It's faint and requires a dark sky to be seen, but photos pick it up more easily. Astrophotographer Jeff Dai captured it from Thailand.
Photographer Jeff Dai captured this self-portrait atop a glacier - 17,000 feet (5,300 m) above sea level - in the Himalayas of Tibet.
High above sea level - and far from light pollution - Tibet offers one of the most breathtaking night skies in the world. A collection of photos by Jeff Dai.
Visible planets in October 2021. Venus, Jupiter and Saturn bright in the evening from all of Earth. Mercury comes into view before sunup after mid-month.
The zodiacal light is an eerie light extending up from the horizon before true dawn begins. Southern Hemisphere? Look after sunset!
New moon comes on August 8, leaving skies dark for the Perseids in 2021. EarthSky's meteor shower guide features dates and times. It can help you plan.
The sun's counterglow - or gegenschein - is kind of a stargazers' legend. What is it, and how can you see it? Erwin Matys and Karoline Mrazek of Project Nightflight explain.
If you're in the Northern Hemisphere, you can see the zodiacal light, or false dawn, at this time of year. If you're in the Southern Hemisphere, look for it after sunset.
And, more to the point, are any asteroids that might be hidden in the Taurid meteor stream potentially hazardous to Earth?
North and South Taurid meteor showers happen simultaneously in late October and November. They're relatively minor showers, but produce a high percentage of fireballs, or bright meteors.
The link between the constellation we know as Orion the Hunter and the Chinese New Year, celebrated throughout Southeast Asia and the world, and coming in 2017 on January 28.
Gravity waves traveling upwards from the lower atmosphere caused this unusual banded structure in airglow above China in late November.
When we look up or down - away from the flat disk of the galaxy or toward it - we're seeing Milky Way stars. But we also see a few more distant objects, visible to the eye alone.
Venus and Saturn were extra close on the sky's dome this past weekend. Now the waxing moon has come back after sunset and is sweeping near them each evening.
The gegenschein, or counterglow, is a faint brightening of the night sky in the region opposite the sun. It's sunlight scattered by interplanetary dust.
Milky Way vs. zodiacal light! Captured over beautiful Yamdrok Lake in Tibet.
"Should there be the same scenery as seen from another place of the Milky Way?"
"When the three stars of Orion shine highly at the southern sky after sunset, that means it’s time for the spring festival."
