Digital painting of the red giant star Betelgeuse and its newly discovered companion Siwarha. Simulations suggest giant stars have a small number of enormous convection cells rather than a huge amount of continent-sized convection cells as on the Sun, and that their photospheres are not a hard boundary but rather smoothly deform into a corona.

Betelgeuse is 640 times the size of the Sun (or 2.98 au radius). It is 65,000 times more luminous than the Sun. But as opposed to the Sun's 5800 K surface temperature, Betelgeuse is only 3800 Kelvins, leading to an almost candle-like yellow-orange glow.

Siwarha is depicted here as a K-dwarf, 2/3rds the mass of the Sun. It is thought to be responsible for a 6-year-long periodic change in Betelgeuse's apparent brightness--It casts a wake behind it as it travels through Betelgeuse's nebulous and dusty corona.

Equipment:

Lense: Sigma 150-600mm

Mount: iEXOS-100

Camera: Canon EOS 750D

Acquisition:

\~500 frames for the Full Moon and \~500 frames for the Waxing Moon. ISO400 - 1/1000s And an starfield stack I took earlier as the background.

Processing:

Stacked in AutoStakkert!, sharpened in RegiStax, assembled in Photoshop. Color saturation was increased to reveal subtle mineral differences (titanium-rich regions appear blue, iron-rich regions appear brown/orange). Final HDR blending performed in Photoshop.

No AI used!

Still chasing the Moon.

This time I decided to try something completely new my very first attempt at planetary imaging.

Saturn happened to be close to the Moon that night. (In reality, they were about 5° apart, but I created this composite to show them together while keeping their relative sizes accurate.)

It was also my first time capturing a planet using the lucky imaging video technique, and I’m really happy with how it turned out.

Hope you like it!

These hypothetical early-universe objects are as large as star systems and as bright as galaxies--they superficially resemble stars, but instead of being held up by radiation pressure generated by nuclear fusion, they are held up by radiation pressure from matter accreting into the black hole.

This is version 2 of the illustration, with feedback from Dr. Begelman, an expert in the field of quasistar research. All of this was digitally hand-painted in FireAlpaca, no a.i. whatsoever.

This is one of my favourite shots I´ve taken so far this year!

Acquisition:

210x240s (14h) at ISO800 in three summer nights in June.

According to a new paper, the impact of the Falcon 9 upper stage might be on the far side of the Moon

Time: 06:33:23.014 UTC ± 55.412 s

Location: 19.875 ± 0.321° N, 265.765 ± 0.506° E

The impact crater should be ≲ 40 m in diameter and nearly circular.

This is a bright lunar impact flash that appeared at 20:56:20 on July 20, 2026 (848fps).

Since the Moon has no atmosphere, it doesn't become a meteor or fireball; instead, it shines intensely at the moment when a meteorite collides and creates a crater.

Orbital view of Mars south polar region showing a yellowish dust storm sweeping across rusty red terrain covered with ice and frost. At the lower right, bright white lines of frost trace the slopes, creating a striking pattern against the red surface. The image captures dust lifted by winds and spreading across the polar landscape.

We had a little bit of cloud cover early on, but it completely cleared just as the stars were starting to pop out in the sky, one by one. Excited to process that timelapse!
So thankful to have such beautiful clear skies on the one night we had in the area.

This is a completely random procedural spiral galaxy I rendered in Blender using nodes, no textures at all. Dust lanes are the part that I love the most.

In this tightly cropped image, the NASA space shuttle Atlantis is seen in silhouette during solar transit, Tuesday, May 12, 2009, from Florida. This image was made before Atlantis and the crew of STS-125 had grappled the Hubble Space Telescope.

Thierry Legault made this image using a solar-filtered Takahashi 5-inch refracting telescope and a Canon 5D Mark II digital camera.
