Perihelion: Apr 19, Mag 3.6, 0.5 AU from Sun, 0.587 AU from earth, inside the orbit of Venus

Nearest approach: Apr 26, Mag 1.2, 0.489 AU from Earth

Here is spectacular image of Comet C/2025 R3 (PanSTARRS), taken at 03:46 UTC April 13, using a 12” telescope at Farm Tivoli, Namibia, by Gerald Rhemann and Michael Jäger, .

It seems the color processing here went astray and a temporarily appearing streak of the plasma tail has been mis-painted as dusty. A dust tail *was* seen for a few days around solar conjunction such as in https://www.facebook.com/photo/?fbid=1262698482516089 thanks to a forward-scattering boost, but already on 29 April it had faded to near-oblivion: https://www.facebook.com/photo/?fbid=1423336013141204 - there were no optical detections in May AFAIK, and so it would be extremely unlikely and even unphysical to see a prominent dust tail now.

The image lies in and around the Orion constellation. The red Barnard's Loop arches above the comet and encloses two distinct Nebulae - the Orion Nebula on the left and the Flame Nebula on the right.

A tiny dark Horsehead Nebula can be seen in the red area to the left of the Flame Nebula.

This image was captured by astrophotographer Luc Perrot a few days ago from France's Reunion Island in the southern Indian Ocean, east of Madagascar.

The short whitish dust tail can be seen pointing up in the image while the long, wavy and bluish ion tail trails off toward the upper left.

The Orion nebula shines on the upper right.

The first thing I noticed was the frequency of satellites. It is disturbing.

Most people in the world cannot see the night sky.

I love seeing people’s long exposure pictures of the night sky. Seems like those sort of images are going to become a thing of the past.

Although I am sure some AI company will offer a tool to strip the satellite tracks away. Thus annoying me a little bit more.

The horror!

How billionaires, one in particular, are destroying the night sky and astronomy.

This is a pic of Comet C/2025 R3 (PanSTARRS), trapped in a celestial cage of light streaks formed by LEO satellites racing across the sky in this 10-minute exposure image.

This is with ~10,000 orbiting satellites. Now, imagine a million of them, each with a solar array ~10x larger.
