The European Space Agency has released a striking new image of interstellar #comet #3IATLAS from its #JUICE spacecraft, which is on its way to Jupiter. You can see a bright halo and long and fainter rays, jets, streams and filaments of gas and dust. πŸ›°οΈβ˜„οΈπŸ”­

Do you remember when #DART struck an asteroid? On September 26, 2022, planetary defense experts aimed the DART spacecraft at #Dimorphos, a little moon of the asteroid #Didymos. It changed the moonlet’s orbit, but also changed the orbit of the asteroid it didn't strike. πŸ›°οΈπŸͺ¨

For the 1st time in a decade, #DeathValley National Park is experiencing a #superbloom! While the park normally sees about 2 inches of rain in a year, it had 2.5 inches between November 2025 and January 2026. The extra rain awakened dormant seeds. πŸŒΌπŸ’§

Hi stargazers! Tomorrow morning, the waning gibbous #moon will be near red #Antares. It’s the brightest star in the constellation of #Scorpius the Scorpion. Can you spot 3 moderately bright stars known as the Crown of Scorpius as well? πŸŒ–πŸŒŒπŸ”­

A new large coronal hole has emerged from the eastern horizon of our #sun. As it moves into a geoeffective position in the next days, the fast solar wind it produces will be sent our way, disturbing our magnetic field and potentially triggering #auroras. Stay tunned:

The Big Dipper's "pointer stars" help you spot #Polaris, the North Star. The #BigDipper is an easy-to-locate star pattern visible from the Northern Hemisphere. Both it and the Little Dipper look like big dot-to-dots of a kitchen ladle.
