This is a real image of what a new solar system looks like. The light from the central star is blocked, so it's possible to see the lanes of cleared-up dust around it. And that small, yellowish blob at lower right? That's a whole, brand new planet.

Today our team released findings on the nature of the interstellar object 3I/ATLAS, based on our first round of JWST observations. The data are incredible: Not only did we detect and map gas and dust in the coma, but we found that 3I is one of the most CO2 rich comets ever seen! Check it out:

Here's the quarter Moon from about a week ago. You can juuust see the Lunar X near the top left, and the Lunar V near the top middle — these are a light-and-shadow effect created by the rims of a few craters near the terminator for just a few hours every first quarter #astrophotography

The waxing quarter Moon of Wednesday, 2025-07-02. The colours are gently enhanced to show the subtle colour differences that exist on the Moon's surface due to varying mineral composition. Near the terminator, both the Lunar X and lunar Y light-and-shadow effects are visible.

Cropped view of the previous image, zoomed into the area containing the previously mentioned Lunar X and Lunar V, which are circled and labelled. The X is formed from the rims of the craters Blanchinus, La Caille, and Purbach, while the V is formed from the rim of the Ukert crater plus a few small craters that surround it.

OMG. Look at the Trifid Nebula. Never seen or known it to be surrounded in full by the blue reflection nebula, and I have photographed it many times. Full announcement happening at 8am LA time (just before the Pulsar Conference starts here), which I think is about 1am Sydney time. Can't wait!

Trying solar photography again, there's some nice active regions right in the middle! AR 4100 is just below centre, and AR 4099 is just above and to the left. AR4100 produced a huge flare earlier that should light up the auroras in the coming nights! #astrophotography 🔭

Photo of the Sun, seen as a white orb with a gentle texture to it and various spots. Active Region (AR) 4100 is visible just below the centre of the disk with 26 spots, and AR 4099 is just above and to the left of centre with 13 spots.
ARs 4096 (bottom left), 4101 (left of 4100), and 4104 (above+right of 4100) are also visible, with 1-3 spots each.
North is approximately down.

First serious attempt at solar photography — lot more detail than I expected at 300mm! AR 4079 is HUGE, I could even spot it without magnification 🤯 #astrophotography #sun

Black and white photo of the Sun. North is approximately down.
Three groups of sunspots (Active Regions, ARs) are visible:
- AR 4079 is the biggest one, at the left side of the sun's disk, with 33 spots covering about 3.8 billion square kilometres.
- AR 4081 is visible near the middle as a smaller group containing 10 sunspots covering approx. 304 million square kilometres.
- AR 4082 is right of centre, containing 8 sunspots covering approx. 426 million square kilometres.

Lagoon (middle) and Trifid (above and to the left of it) nebulae in Sagittarius, ~21m37s exposure Plenty more neat stuff in this field too, including one other Messier object + a few globular clusters (NGC 6544 just below Lagoon, NGC 6553 a little further down) etc #astrophotography #astrofotografia

Picture of a region of sky around the Lagoon Nebula (near centre) and the Trifid Nebula (above and to the left of the Lagoon), both in Sagittarius. The Lagoon Nebula is seen in mixing shades of pink, cyan, and white, while the Trifid has two distinct sections, one in magenta and one in blue/cyan. The Trifid's magenta section, an emission nebula, has dust filaments that appear to cut it into thirds, giving it its name. Its blue/cyan portion is a reflection nebula.
The field covers an area approximately 6.5 degrees wide by 3.7 degrees tall. A few open and globular clusters can also be seen in the image. A bright area containing dust, gas, and stars from the central region of the Milky Way is visible at the bottom right.

Last night's quarter #Moon, colour enhanced to showcase the variance in lunar mineral composition #astrophotography #astrofotografia

The Moon, approximately half illuminated as seen on the 4th of May, 2025.
The colours have been somewhat enhanced to better display the variability in the Moon's mineral composition, with blue hues hinting at higher concentrations of titanium minerals and redder hues suggesting higher concentrations of iron.
Mare Tranquilitatis is notably bluer than average, while Mare Serenitatis is gently redder.

Had another go at processing the Carina Nebula, with the same data as last time — might have to stick with Siril from here onwards 🫨 #astrophotography #astrofotografia

Photo of the great nebula in Carina, also known as NGC 3372. The main body of the nebula appears as if it's divided in thirds, with many shades of red, blue, and cyan colouring the area. Eta Carinae, a very active binary star system containing a luminous blue variable star, and its associated Homunculus Nebula, are located in the upper of the three thirds, with many thousands of other stars covering the rest of the field.

Stunning colours! Blue stars are the hot ones (like the blue part of a flame), the white stars are a little cooler and orange / red stars are the coolest. Antares is a red supergiant star, nearing the end of its life. It will one day explode as a supernova and become a neutron star / pulsar! 🔭🧪

Kalb al Akrab — Antares, the heart of the Scorpion, and the loads of dust and other stars in its region in the sky. Might even have snuck in an asteroid or three in there :) #astrophotography

Photo of the region surrounding Antares (bright orange star near the middle of the picture) in the sky. Thousands of stars in various shades of orange, blue, and near white can be seen in the field, which has a limiting magnitude of approximately 13.2.
Some of the nebulae in the Rho Ophiuchi Cloud Complex can be faintly seen near the brightest stars, including IC 4606 (Antares), IC 4605 (i Sco), IC 4603 (HIP 80462), IC 4604 (rho Oph), SH 2-9 (Alniyat). Many dark dust clouds are also visible through the area, especially to the left of Antares, spreading towards the bottom left of the image.

First go at the #Moon in HDR, with a bit of colour enhancing on the sunlit side, from a couple nights ago. Earthshine was looking amazing! #astrophotography

The Moon, about 37.5% illuminated. The sunlit side is colour-enhanced to show mineral content variation on the surface. The unlit side is dimly illuminated by light reflected off the Earth — the so called earthshine.
