View Comet SWAN online

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.

Online viewing of large asteroid rescheduled for April 29

A cloudy sky last night prevented the online viewing of large, close-passing asteroid 1998 OR2. The Virtual Telescope Project will be trying again today to show you the asteroid, which passed us earlier today.

Will you see BepiColombo’s goodbye flyby on April 9?

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.

Comet ATLAS possibly disintegrating.

Is bright Comet ATLAS disintegrating?

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.

No, asteroid 2007 FT3 won’t hit Earth in October

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.

ESA and ESO confirm asteroid will miss Earth in September

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.

A small asteroid hit us last weekend

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.

Video: Asteroid 1999 KW4 as it swept past

It wasn’t visible to the eye, but some telescope users in Earth’s Southern Hemisphere caught it at its May 25 closest approach. Now Northern Hemisphere observers will get their chance. Charts here, and check out this cool video!

Another asteroid disintegrates over Russia

A bright meteor was caught in many dashcam videos – in broad daylight – on April 6, 2019, over the Russian city of Krasnoyarsk. See a video compilation here.

Speedy asteroid buzzed Earth last week, 1 day before being detected

A small asteroid – now designated as 2019 FC1 – flew closer to us than the moon on March 28, 2019. Astronomers detected it 1 day later. It’s the largest of 14 asteroids to pass closer to us than the moon since 2019 began.
