Pick Your Cosmic Cataclysm from the Latest Alerts!

Cataclysmic events are happening every night somewhere in the observable Universe. Our goal is to catch them.

Be the first to observe a transient event like a supernova, gamma-ray burst, or maybe a phenomenon as yet unknown to humanity. These cosmic happenings are unpredictable and short-lived, so we need to observe them as soon as they appear.

Cosmic Alert Targets

Visibility note: If your observing location's latitude is within +/- 70 degrees of the target's "Dec" value (its first number), then the target is likely visible to you. The closer your latitude is to the Dec, the higher in the sky the target will rise for you. We will be adding maps soon to make determining visibility easier.

Finder images have been temporarily removed. If you use the deeplink or RA & Dec coordinates from the table below, there is no need to check your field of view.

Highest priority targets are those with the most recent "Discovered" date. But we still want to collect observations for all targets in this table.
