So yes, I know the satellite trails can be processed out of the comet image I shared earlier. Here's a fully processed version showing Comet Pons Brooks on the evening of 4th May. The comet was very low in the sky from New Zealand at the time the images from which this composite has been assembled. #comet#ponsbrooks#NewZealand

In early 2023, a new comet took stargazers by surprise. Called Comet C/2023 A3 (Tsuchinan-Atlas), this icy visitor was discovered by two separate observatories in South Africa and China. Comet A3 had scientists and amateurs alike wondering if it would be the next naked-eye comet to light our skies. As 2024 unfolds, we eagerly anticipate whether Comet A3 will deliver the breathtaking celestial display we have all been hoping for!
#PPOD: In dark evening skies over June Lake, northern hemisphere, planet Earth, Comet 12P/Pons-Brooks stood just above the western horizon on March 30. Its twisted turbulent ion tail and diffuse greenish coma are captured in this two-degree wide telescopic field of view along with the bright yellowish star Hamal also known as Alpha Arietis.

Here is another picture of Comet Pons Brooks from last night. This was taken by merging/median combining 35 images taken using a 93mm refractor to remove the shitty Starlink satellites. The ion and dust tails from the comet are clearly visible as is its green coma! #astronomy#NewZealand#comet#cometponsbrooks
WOW! Comet C/12P Pons-Brooks was epic this evening. Visible to the naked eye from Strath Taieri. This is a single shot as the comet was setting behind some clouds! Its altitude was under 2 degrees! #comet#NewZealand
#PPOD: How does a comet tail change? It depends on the comet. The ion tail of Comet 12P/Pons–Brooks has been changing markedly, as detailed in the featured image sequenced over nine days from March 6 to 14 (top to bottom). Reasons for tail changes include the rate of ejection of material from the comet's nucleus, the strength and complexity of the passing solar wind, and the rotation rate of the comet.

Here is another picture from tonight's road trip to photograph comet Pons-Brooks. Bit of a challenge actually. 1-hour drive, 2 telescopes to set up, and the bloody comet would just be 2 degrees high an hour after sunset. But there was nothing on TV so why not. #Comet#Astronomy#NewZealand
#PPOD: Comet 12P/Pons-Brooks graces the evening sky above the summits of Kežmarský štít (8,389 ft/2,557 m), at right, and Lomnický štít (8,635 ft/2,632 m), at left in the Tatra Mountains of Slovakia. At the summit of Lomnický štít is a small domed building. This structure is the Skalnaté pleso Observatory, one of the highest astronomical observatories in central Europe.

[#ScienceNews@IRAP ] In 2029, the ESA and JAXA joint #CometInterceptor mission will take off from the Kourou Space Center aboard an #Ariane6. Objective: to study a #comet in its original state - or even an object of interstellar origin.
On March 5, @IRAP delivered the functional electrical model of the Low-Energy Electron Spectrometer (1 eV-1 keV) which is part of the #DFP (Dust, Fields, Particles) experiment. The future is on the way! 👍
This is the surface of a comet! Dust is swirling around the surface of Comet 67/P -- captured in 2016 by ESA's Rosetta spacecraft, processing by Jacint Roger Perez.
Still one of the most remarkable scenes in space exploration.
An exploding, green “devil comet” is zooming past the Andromeda Galaxy as it races toward Earth, creating some astonishing nighttime photo opportunities. Live Science has more: https://flip.it/by8-I9 #Science#Space#Comet#Earth
