Astronomy is becoming an online affair. A recent find shows what’s possible, as devoted amateur astronomer @filipp-romanov.bsky.social discovered a supernova in a remote galaxy.

Here’s our latest post on the find and how he did it for @universetoday.com - www.universetoday.com/articles/ded...

Dedicated Amateur Discovers Supernova in Remote Galaxy

Astronomy is increasingly becoming an online affair. Recent discoveries of interstellar Comet 3I/ATLAS and R2 SWAN highlighted this fact, when both were first discussed on message boards and verified ...

What are solar storms and the solar wind? 3 astrophysicists explain how particles coming from the Sun interact with Earth

Space weather isn’t referring to rain clouds that float through the galaxy. Instead, it’s caused by massive explosions of particles that shoot out from the Sun.

Off and away… there was a successful sub-orbital rocket launch early this morning from Andoya Space Center in Norway. This was in support of DLR’s ATHEAt campaign (the Advanced Technologies for High Energetic Atmospheric Flight of Launcher Stages) testing tech for future reusable space vehicles.

Titan shadow events happen when the rings are near edge on as seen from the Earth. After tonight, Titan won’t resume casting its shadow on Saturn again until July 29th, 2039. Here’s our post of the 2025 Titan shadow season for @universetoday.com - www.universetoday.com/articles/ast...

Astro-Challenge: See Titan's Shadow Cross Saturn

Nothing wows new observers like seeing Saturn for the first time. I always check out the ringed planet if it's visible, and telescopes down the line at any star party will invariably be pointed Saturn...

Titan casts its shadow on Saturn one last time for 2025 tonight at 3:50 Universal Time (UT) until 7:23 UT. Saturn is currently 2 weeks past opposition, rising in the east when the Sun sets in the west. The event favors viewers along the longitudes of the Americas. youtu.be/YDqTWpFVUgU

@asrivkin.bsky.social @planet4589.bsky.social @noisyastronomer.com @philplait.bsky.social The AMS Fireball page and the video seem to show an east-west trajectory. My money's on a meteor/bollide. I didn't see any good fits for a sat reentry, though Space-Track is lagging on updates.

I would really rather not die of what was once a worldbuilding detail in an early 80s science fiction story.

If I can't die with a full bar tab, I need to be eviscerated by the ravenous Bugblatter Beast of Traal after saying "How cute!" and going pss pss pss.

The 83.2% waxing gibbous on Friday evening.
Earlier the moon occulted Gamma Capricorni, ingres at 6.01 PM (UTC+7) and egress at 7.09 PM.
Here, I only captured the egress.
