Computer simulations confirm that 'Oumuamua - an object from another star system that sped near our sun in 2017 - likely formed via a close encounter with its star. 'Oumuamua may have originated in a debris disk, they said, or even a shattered super-Earth.
Colombia University's Earth Institute in New York and host Andrew Revkin bring you a Sunday morning online session featuring musicians and experts in human sustainability on planet Earth.
Anak Krakatau (Child of Krakatau) volcano began erupting last night - Friday, April 10, 2020 - according to clocks in Indonesia. The eruption is not thought to be major, although it's the longest eruption since 2018. Webcams and satellites caught its awesome beauty.
The European-Japanese Mercury mission, BepiColombo, completed its first flyby last night, sweeping near Earth. The gravity assist fine-tuned the craft's trajectory. BepiColombo's images during the flyby show Earth shining in darkness.
BepiColombo is a spacecraft on a roundabout journey to Mercury. It'll sweep near Earth tonight, using Earth as a gravity slingshot to send it hurtling toward the inner solar system. For most of us, BepiColombo will pass unseen. But people with telescopes might spot it! Charts and more here.
This week, Venus - the brightest planet and dazzling "evening star" - will pass the beautiful Pleiades star cluster, also known as the Seven Sisters. Look west after sunset! Venus and the Pleiades meet only every 8 years. Photos here.
How're you doing out there? We want to see you and hear from you! Post your selfie at EarthSky Facebook, or at EarthSky Community Photos, or in the comments section of this post.
The moon swept past the morning planets last week, and the EarthSky Community did a great job capturing each day's view. Thanks to all who contributed photos to EarthSky Community Photos and to our Facebook page!
We're between the extremes now, in a place of balance, near an equinox. This composite image shows how the sun moves along your horizon each day at sunset and sunrise, as Earth moves in orbit around the sun.
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.
