We suspect most of you have not seen this comet, which is rising only shortly before the sun now. Let the Virtual Telescope’s Gianluca Masi show it to you online this week.

Comet C/2019 Y4 (ATLAS) has been fainter during the last few nights. It’s possible it’s disintegrating (as comets sometimes do). Details here.

Why is the internet so chock-full of stories about asteroids on a collision course with Earth? At this rate, we should have been obliterated many times over already. Here comes the newest scare story: asteroid 2007 FT3. No, it won’t hit us, either.

Asteroid 2006 QV89, a space rock that’ll pass closest to Earth on September 9, will not strike Earth. Details here, including a recent, fortunate non-detection of the asteroid by ESA and ESO.

Asteroid 2019 MO exploded in our atmosphere with an energy of about 3 to 5 kilotons of TNT. Such events happen once or twice yearly, astronomers say. Most are unexpected, but this space rock was detected hours before it struck.
