Comet 46P/Wirtanen is 2018’s brightest comet, but that doesn’t mean it’s bright. Although theoretically visible to the eye now, the comet is large and diffuse … not easy to see. Charts, tips and other info here.
This comet is due to pass closest to our sun and Earth in December 2018. It’s already the brightest comet in the night sky, visible to astronomers with telescopes and binoculars. A new image shows the comet’s rotation!
Japan’s Hayabusa2 spacecraft deployed the MASCOT lander to asteroid Ryugu yesterday. Now, MASCOT has returned its 1st image. An international team of engineers and scientists in Germany is standing by.
Comet 21P/Giacobini-Zinner came closer to Earth this week than it had in 72 years. Favorite photos here, from the EarthSky community. Plus info on comet Wirtanen, which might become visible to the eye alone later this year.
