feeling a little bit green right now

Comic. [Two people, one with ponytail and one with beret, sitting on a boat fishing. Below the water, the person with the beret’s fishing line has caught on a large rock on the bottom.] PERSON with beret: It feels like a big one! At least 10^24 kilograms!

Potential Discovery of a World Next Door JWST provides new evidence that one of our nearest neighbor stars, Alpha Centauri A, might host a giant planet in its habitable zone.

Camera: ZWO ASI 2600MM + Baader 36mm filters Scope/Mount: APM TMB-LZOS 152/1200 at 900 FL / CEM120EC2 Subs: 48 x L @ 600 sec, 21 x RGB @ 600 sec @Gain 0, Offset 20 Acquired using ekos/indi and processed in PixInsight - includes using the various XTerminator tools. The Antennae Galaxies are two galaxies about 45 million light-years away in the constellation Corvus that are interacting in a galactic collision to form one giant galaxy in the future. The name was given because of the two long tails of stars, dust and gas ejected from the galaxies from the collision that resembled an insect's antennae. This image was processed using data acquired in April and June 2024 from the Flaxton Dome and has a total integration of 18.5 hours.

Antennae Galaxies NGC 4038. This is a reprocess of data I got in 2024. It's one of the images that will be going into my club's 2026 Calendar.

A photo of a reflection nebula and surrounding dark nebula. In the center is a bright star, whose blue light reflects on all of the dust structures near it. The further from the central star you look, more dark patches of cloud fill the frame. Some of the dark nebula are so murky and dense that they block out all starlight.

I spent 5 nights recently shooting the Iris Nebula. In the end, I had about 20 hours of usable LRGB data to play with. I'm so happy with amount of detail I was able to pull out on the dark nebula clouds.

You can see Titan’s shadow on the upper left of Saturn. In my next picture taken about 30 min later, you can see the shadows moved towards the center of Saturn, due to the orbit of Titan, wrt the location of the sun. My 3rd pic is purposely over exposed to show the moons Rhea (far left), Titan left high above the rings, and Dione (right immediately above the ring). Titan is the 2nd largest moon in the solar system (Jupiter’s Ganymede is the largest). To put that in perspective, Titan is larger than the planet Mercury. The 15-year-ish cycle is due to Saturn’s tilt on its axis, so like Earth, it has seasons. Its long slow orbit around the sun account for the long cycle. So for a shadow to be seen from Earth, Titan must be in just the right spot. Titan orbits Saturn once every 16 days, so we actually get to see the shadow about a half dozen times on a 16 day cycle during the transit year. Then Saturn’s tilt changes enough and the shadow no longer hits Saturn. Aug 29, Sept 4, and Sept 20 are the last chances to see the transit. You will need a pretty good telescope, however to see the shadow. I tried my 4” 900 mm refractor, but was disappointed. Tech stuff: Scope 11” SCT focal length 3000 mm Mount: ZWO AM5N Camera: ZWO 533MC Video: about 40% of 2000 frames stacked

Titan’s shadow mid transit, Aug 3 4:50 AM, EDT

Saturn’s moons Rhea (far left), Titan (left above the rings), Dione (right just above the rings).

Saturn’s moon Titan casts its shadow on Saturn where we Earthlings can see it once every 15 (or so) years. Even then, you have to be in the right location. North America was the right location for 2025. I took these last night.

Finally had a couple of hours of clear sky last evening so I let the telescope out for a little more than two hours clock time, but only about an hour of actual exposure, so Cygnus was already up in the east and the Western veil nebula was calling me.

Wizard nebula. Processed in the SHO Hubble palette

Haven't shared anything for a while

This is the Wizard nebula, taken over several nights over the last few weeks.
14 hrs total exposure spread equally between S,H and O filters. Stars used RGB filters

A telescopic image of a dense region of stars. At center is a dark cloud that resembles the letter S. A smaller dark cloud is to the right of it.

Captured last night: The Snake, aka Barnard 72, a dark nebula in the constellation of Ophiuchus, which ironically is the Serpent Bearer. At right is another dark nebula, Barnard 68. 🔭

Photo of a bright blue star embedded within a dense cloud of dust. The star is illuminating the interior of the cloud, giving it the appearance of a beautiful blue flower.

The Iris Nebula, imaged over the last 3 nights (one night per color channel - although thanks to dew issues a good deal of my data had to be dumped). Still, this nebula is bright enough that even with what was left over I think I was able to get a decent result! 🔭

Face-on spiral galaxy NGC 6946 and open star cluster NGC 6939 share this cosmic snapshot, composed with over 68 hours of image data captured with a small telescope on planet Earth. The field of view spans spans about 1 degree or 2 full moons on the sky toward the northern constellation Cepheus. Seen through faint interstellar dust couds near the plane of our Milky Way galaxy, the stars of open cluster NGC 6939 are 5,600 light-years in the distance, near bottom right in the frame. Face-on spiral galaxy NGC 6946 is at top left, but lies some 22 million light-years away. In the last 100 years, 10 supernovae have been discovered in NGC 6946, the latest one seen in 2017. By comparison, the average rate of supernovae in our Milky Way is about 1 every 100 years or so. Of course, NGC 6946 is also known as The Fireworks Galaxy.

Here's our images of interstellar object #A11pl3Z from Deep Random Survey's 0.43-meter scope @ Chile. The telescope was following A11pl3Z's motion, so stars appear smeared. Weather got worse by the end, so still hard to tell if it's a comet.

I've revisited my ISS solar transit images.
The detail visible is clearer when shown in mono, as captured by the camera, without artifitially colourising the image.

A pride flag with every color band represented by a NASA image. White is Earth clouds, pink is aurora, blue is the Sun in a specific wavelength, brown is Jupiter clouds, black is the Hubble deep field, red is the top of sprites, orange is a Mars crater, yellow is the surface of Io, green is a lake with algae, blue is Neptune, and purple is the Crab Nebula in a specific wavelength.

I made this Pride flag using only NASA images and our team thought it would be cool to share on social (I work on the NASA heliophysics communications team), but it's getting all sorts of hate on the bird app and Fbook. Thought y'all might be more appreciative of it here. ☺️🏳️‍🌈💖

i saw this on my TL and went "hell yeah" so hard before realizing it was about the soviet cosmonaut named Yuri Gagarin
