Comet C/2025 R3 (PanSTARRS) is now putting on a show, visible low in the predawn sky, with binoculars or telescope.

Comet C/2025 R3 (PanSTARRS) is featured in today's NASA APOD.
This image was taken by astrophotographer Haythem Hamdi, in Rhode Island, USA, on April 12. It captures the comet’s glowing coma and flowing tail shaped by the solar wind. Haythem used an Askar 80PHQ refractor and reducer to get a wide field of view for framing the long tail.

11/nLooks like Comet C/2025 R3 (PanSTARRS) survived its trip around the Sun and is now on its return trip out of the Solar System.
The comet makes its closest approach to Earth today.
These are images captured by the ESA/NASA Solar and Heliospheric Observatory (SOHO) LASCO C3 instrument.

12/nThe ESA/NASA Solar and Heliospheric Observatory (SOHO), launched on Dec. 2, 1995, has been studying the Sun for over 30 years, from its perch in a Halo orbit around the Sun-Earth Lagrange point L1.
With its 12 instruments, SOHO allows scientists to study the Sun’s internal structure and dynamics, the chromosphere, the corona, and solar particles. It has discovered over 5,000 comets.

13/nThe horror! 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.

14/n@AkaSci that is a great and saddening picture.
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.

14/n@AkaSci I have recently moved to where I can see the night sky. The first thing I noticed was the frequency of satellites. It is disturbing.
Most people in the world cannot see the night sky.

14/nAs Comet C/2025 R3 (PanSTARRS) heads out of the inner Solar System, it is putting on quite a show for enthusiasts and photographers.
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.
