Excited to now share this story; papers have been accepted!
Apep is an awesome system, unlike any other we know about. It is named after the Egyptian God of Chaos - because, well, it is chaos!
Two Wolf-Rayet systems orbited by a third supergiant. As all their winds collide, they form these beautiful structures that have now been observed with #JWST and ESO's VLT.
I had a chat with fellow student from Macquarie Uni. Ryan White who has led one of the two papers that are released about this.
My latest for #SpaceAustralia

The Ejecta Nebula Around the Wolf-Rayet Star WR 71: https://arxiv.org/abs/2507.17946 -> "deep H and [O III] images of the ejecta rich nebulosity associated with the suspected runaway and binary #WolfRayet star WR~71 (HD 143414). [...] Deep H and [O III] images like those presented here suggests that new and substantially deeper imaging reconnaissance of WR star nebulae compared to earlier surveys may lead to additional WR ring nebula detections, thereby enhancing our understanding on the frequency and formation of WR ring nebulae."

I hope you’re okay with a steady stream of these… today another astronomical fantasy of zooming in on a Wolf-Rayet star for data-gathering 😊

@jeffzugale no, but I have colleagues who do… I’ll try to get them to see your work!

Have been observing with Parkes on the graveyard shift most of this week, and to keep myself awake I spent a bit of time processing some data from #JWST target: Wolf-Rayet 124.
These stars are hot, massive stars with stellar winds that are literally shredding the star's outer layers, creating this massive, beautiful and bright nebula. They're also some of the hottest stars known and are precursors to violent supernova events This one is about 15,000 light-years away.
The two different instruments on the JWST sees different features, and so we see different structures of this ferocious star. To generate these, I used four base tones in each and stacked as best I could.
On the left is the NIRCAM instrument, with filter F444W. On the right is the MIRI instrument with filter F1800W.

This 360° visualization based on data from Chandra and other telescopes shows ~25 Wolf-Rayet stars around the Milky Way's supermassive black hole Sgr A*.
The movie shows 2 simulations, each of which start around 350 years in the past and span 500 years. The 1st one shows Sgr A* in a calm state, the 2nd has a more violent Sgr A* that is expelling material, thereby preventing accretion of clumped material (yellow blobs) prominent in the 1st section.

Dozens of massive Wolf-Rayet stars are known to orbit within 1.5 ly of the central super massive black hole Sgr A* in our own galaxy.
The fierce stellar winds of the WR stars collide with each other creating shock waves and clumps of gas and dust, which heat up to millions of degrees and emit X-rays. Some of these clumps spiral into the black hole. Some of the material gets ejected into interstellar space.

This study from 2012, using 24 µm data from Spitzer, revealed that the ionized gas of nebula M1-67 ejected by WR 124 is condensed in knots aligned in a preferred axis along the NE-SW direction, with “holes” along the perpendicular direction.
The sketch below illustrates the (proposed) structure as an inner region with bipolar or elliptical shape along the direction NE−SW surrounded by an external spherical bubble.

This image of the Wolf-Rayet star WR 124 and Nebula M1-67 was released by the JWST team today at #SXSW. The image was taken using the NIRCam and MIRI instruments in June 2022.
The 2nd image was taken by Hubble in 1998 and re-processed in 2015 by @spacegeck.
The massive young hot star is expelling star-stuff at ~200 km/s into the surrounding nebula.
It will explode as a type Ib or Ic supernova in a few 100,000 years.

The rare sight of a #WolfRayet star – among the most luminous, most massive, and most briefly-detectable stars known – was one of the first observations made by NASA’s James #Webb Space Telescope in June 2022: https://webbtelescope.org/contents/news-releases/2023/news-2023-111 and https://www.esa.int/Science_Exploration/Space_Science/Webb/Webb_captures_rarely_seen_prelude_to_a_supernova - Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments NIRCam and MIRI from 900 nm to 18 µm; t The star is 15,000 light-years away in the constellation Sagittarius.

Wolf-Rayet stars are a category of different types of stars which are all, frankly, horrifying.
Surface temperatures up to 210k K, which is figuratively hot enough to burn our sun (10k K).
Stellar winds so strong they're constantly ripping the star apart, creating nebulas with ejecta chunks as big as the distance from Earth to Saturn.
There's one that's 4.7 million times as luminous as the sun.Image: WR124 by @spacegeck
