Arecibo Observatory damaged by broken lashing cable

The new damage to Arecibo, caused by the heavy cable, happened while repairs from 2017’s Hurricane Maria were still ongoing.

How to see Comet NEOWISE

A few observers in the Southern Hemisphere are beginning to capture Comet NEOWISE, too. Charts here for seeing the comet in late July and early August.

Biggest asteroid to pass close (and undetected) this year

Asteroid 2020 LD passed within the moon’s distance on June 5, but wasn’t discovered until June 7. It’s the 45th known and the largest asteroid to sweep within a lunar-distance of Earth so far in 2020.

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.
