Do your skies look hazy? Are your sunsets very orange, or layered-looking, or does the sun or moon look orange while high in the sky? If you're in the northern U.S. or Canada, the reason is still wildfire smoke.
Saturn has 62 moons with confirmed orbits, 53 of which have names and only 13 of which have diameters larger than about 30 miles (50 km). Here are 7 of them!
A new computer modeling study shows that - some 4 billion years ago - a barrage of incoming debris from space likely formed what we know today as Earth’s oldest rocks.
Decades of work have gone into probing the heart of our Milky Way galaxy. Click in for a video showing stars orbiting the 4-million-solar-mass black hole at our galaxy's core.
Computer modeling suggests that - billions of years ago, when our solar system was young - a star swept near, stealing some of our sun's material and creating the odd orbits of Kuiper Belt objects.
Launch of the daredevil Parker Solar Probe - which will get closer to the sun than any spacecraft in human history - has been delayed until Sunday, August 12.
A pyrocumulus cloud - sometimes called a fire cloud - forms when intense heat from wildfires causes air to rise. Californians have been seeing these towering clouds this July and August.
Deborah Byrd (asteroid 3505 Byrd) helps edit EarthSky.org and is a frequent host of EarthSky videos. Deborah created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. Prior to that, she had worked for the University of Texas McDonald Observatory since 1976, and created and produced their Star Date radio series. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named in her honor in 1990, a Public Service Award from the National Science Board in 2003, and the Education Prize from the American Astronomical Society in 2020. A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says.
