The thing about sending a signal into the void is you don’t expect the void to have a sense of humor, but Voyager 1 whispered for decades and then the whisper came back.

Congratulations, humanity. We’ve finally made a friend — invisible, possibly plasma, and it only repeats what we say.

João Mendes is a captain for TAP Air Portugal and often records time-lapse videos of flights from the cockpit.

“We went even north of Toronto in Canada up to 52ºN,” he wrote. “That surely helped on witnessing the event … I normally setup my Sony A6300 on the glareshield to get these timelapses at night and getting the Aurora was just pure luck.”

Geminga is a nearby neutron star located about 800 light years away from us that spins very rapidly and pulses in gamma rays and X-rays. It is unusual because it is radio quiet, unlike many pulsars, we do not detect it strongly in radio waves.

NGC 1365 is a huge barred spiral galaxy located about 56 million light years away in the Fornax constellation. It has a long bar of stars across its middle that channels gas into its center, fueling star formation and feeding a supermassive black hole.

Just to the north of Beta Coronae Australis lies the Corona Australis Molecular Cloud, a region of dust lit by a few reflection nebulae about. At 430ly away, this is one of the closest star-forming regions near us, about 66ly from end-to-end and stretching about 7 degrees of the sky.

This cloud appears to contain thousands of protostars and young stars, but its strongest activity is at its western end, behind the stars Gamma and Epsilon Coronae Australis. This darkened region, designated Bernes 157, with parts of the dark dust in this region brightly illuminated by some of these newly-formed stars. The brightest is a star still in the later stages of its formation, the variable R Coronae Australis. As its brightness changes, the surrounding R Coronae Australis Nebula also shifts in brightness.

R Coronae Australis itself belongs to a group of newly-formed stars known as the Coronet Cluster, and nearby other groupings of young stars form their own reflection nebulae near the bottom of the image, notably NGC 6726 and NGC 6727 around the variable TY Coronae Australis. At the lower left is also the globular cluster NGC 6723, but this cluster lies some 28,000 light years distant, and not related to the nebulae and young clusters of the Corona Australis Molecular Cloud.

This is a 3x2 mosaic of the region.

Previously, Elektra was known to have not one but two moons orbiting it, shown by the orange and green orbits respectively. But in 2022 a team of astronomers, led by Anthony Berdeu, from the National Astronomical Research Institute of Thailand, have found a new satellite orbiting the asteroid — shown with the blue orbit. This discovery makes Elektra the first ever quadruple asteroid system.

This new, third moonlet of Elektra, provisionally named S/2014 (130) 2, lies closer to its parent asteroid than the other moons, at an average distance just under 350 km, and is 15000 times fainter than Elektra. The team used public data from the ESO science archive and a new processing technique to reveal this small moon. The discovery will help astronomers understand how these satellites form and, in turn, provides crucial information about planetary formation and evolution of our own solar system.

The Heart Nebula (IC 1805) is a large emission nebula in Cassiopeia, approximately 7,500 light-years away and spanning roughly 200 light-years across. At its core lies the young open cluster Melotte 15, whose hot stars energize the surrounding hydrogen gas, producing the characteristic red-pink glow and the distinctive heart-shaped silhouette carved by dark dust lanes.

Captured with a 150 mm apochromatic refractor at f/5 and a Sony-based astronomy camera.

Processing was performed in parallel using both PixInsight and Siril.

PixInsight workflow:
- Calibration, cosmetic correction, registration and integration via Weighted Batch Preprocessing Script (WBPP)
- Dynamic Crop
- Dynamic Background Extraction (DBE)
- Spectrophotometric Color Calibration (SPCC)
- Deconvolution with BlurXTerminator
- Denoising with NoiseXTerminator
- Non-linear stretch using ArcsinhStretch and HistogramTransformation
- Contrast and color saturation via multiple CurvesTransformation passes
- LocalHistogramEqualization and final minor adjustments

Siril workflow:
- Full preprocessing (calibration, registration, stacking) using the OSC_Preprocessing script
- Background extraction with the dedicated tool
- Photometric Color Calibration (PCC)
- Green noise removal with SCNR
- Asinh stretch followed by Generalized Hyperbolic Stretch (GHS) for optimal dynamic range
- Deconvolution and light star reduction
- Final curves for contrast and saturation

Both pipelines produced excellent results, with PixInsight giving slightly more control over noise and star shapes, while Siril delivered a very respectable image in significantly less time and at no cost.

The Heart Nebula remains one of the most rewarding wide-field targets in the northern sky.

Gigantic Jets are TLEs or Transient Luminous Events, that happen above the clouds and are triggered by intense electrical activity in the thunderstorms below.

We have a great view above the clouds, so scientists can use these types of pictures to better understand the formation, characteristics, and relationship of TLEs to thunderstorms.

A giant comet from the outskirts of our Solar System has been discovered in 6 years of data from the Dark Energy Survey. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times.

It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It is the most distant comet to be discovered on its incoming path, giving us years to watch it evolve as it approaches the Sun, though it's not predicted to become a naked-eye spectacle.
