The moon is going to blot bright planet #Jupiter from view at 10 UTC on October 6! Wow! It's gonna be cool.

Many in North America and beyond will be in the "occultation path" and able to see it.

EarthSky's Marcy Curran has details. Watch her video here.

For the 1st time, scientists have found helium gas escaping from the atmosphere of an #exoplanet.

It means this distant world might have a temperature that could let liquid water exist on its surface. Could it also support life?

Saturn's opposition is today. 🪐

Earth takes a year to orbit the sun — while #Saturn takes nearly 30 years. So every year, we gain a lap on Saturn.

This is a great time to see Saturn!

Big day for #Saturn! It's at opposition — opposite the sun — today.

How can you identify it? It’s brighter than any star in the east after sunset now. Look east after sunset!

A fainter star, #Fomalhaut, is nearby.

The October morning sky features 3 bright #planets that you can see before dawn. The brightest — Jupiter — is visible before dawn and follows red Mars across the sky. And Saturn is setting in the west. Visit EarthSky’s night sky guide at: https://t.co/WXlU908Uzu

The anticipated solar materials and magnetic fields have arrived! But didn’t trigger the expected G1 (minor) geomagnetic storm. Forecasters consider G1 levels still possible today, once fast solar wind from a coronal hole joins in. Read more: https://t.co/LMvKuBfeHL
