Deborah Byrd created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. Today, she serves as Editor-in-Chief of this website. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. 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.
An international team of astronomers has mapped a piece of the cosmic web without using bright quasars for the first time. They did it by turning a powerful instrument to a single region of the sky for hundreds of hours.
April 2021 showcases 3 bright planets. Mars is the only easy-to-see bright planet in the evening sky. Jupiter and Saturn adorn the early morning hours. Mercury and Venus hover too close to the sun’s glare for easy viewing.
Apophis’ flyby in early March 2021 enabled astronomers to conclude there’s no chance this asteroid will strike Earth anytime soon. “A 2068 impact is not in the realm of possibility anymore,” one scientist said, “and our calculations don’t show any impact risk for at least the next 100 years.”
The zodiacal light is a strange pyramid of light that extends from the eastern or western horizon, before dawn or as true darkness falls. It was known to stem from dust moving in the plane of our solar system. The Juno spacecraft has found that Mars might be the source of the dust.
