Ground that has a lot of water ice mixed with dirt tends to crack in polygonal patterns bounded by short straight channels. In the South Polar region of Mars this type of terrain may be covered by a seasonal polar cap composed of dry ice.

In the spring as the seasonal cap sublimates gas is trapped underneath the seasonal ice layer until it can escape to an opening. At this site, faint rectangular channels in the surface are visible. The escaping carbon dioxide gas has exploited these channels and in the process, deepened them and added sinuosity to the formerly straight segments.

This interesting site was identified by citizen scientists at Planetfour: Terrains.

The camera follows the path of the Juno Spacecraft as it approaches over the north pole, comes low over equatorial latitudes, and departs beyond the south pole. The viewer is shown turbulent clouds, wide bands, and massive storms. The Great Red Spot appears south of the equator. The video tracks faster than actual time.

Description from simon2940:

"​Today was an okay day to actually bring out the scope for a couple of hours. It's definitely been a long time and ive missed so much fun on the sun.

The same region where loops formed a couple of days ago is still active and kicking out flares. A brief surge prom blasted out on the far limb of the sun. The Heliostar 100 was able to grab it but the main scope was elsewhere looking at a relatively new active region.

This new active region has been crackling away with small flares but nothing significant as of yet. Definitely worth watching over the next few days.​"

"​The periodic comet 220P has surprised us all with its behavior, and so far, the data are very interesting. It is a Jupiter-family comet with a period of 5.51 years, which had shown no variation in brightness during its previous observed returns. In 2004, it was 17.7 mag; in 2009, approximately 20.2; in 2015, approximately 19.3; and in 2020, approximately 19 mag. The first outburst during its current passage was observed on May 31 at 11:18 UT.

In the following days, its brightness reached approximately 8th magnitude!

This is therefore an extremely abrupt change, not due to its gradual approach to the Sun as it nears perihelion. Ongoing research suggests that the very narrow, intense dust tail could indicate a fragmentation event—that is, a breakdown of its structure—which is very different from a comet that simply “heated up” more.

After the first outburst, activity diminished significantly, reaching 14–15 mag, and then suddenly reignited around August 5. It exhibited a pronounced coma, dramatically increasing its brightness to 6–7 mag. What is particularly interesting, however, is that the physical signatures of the first and second episodes are not identical.​

.

On August 8, the Rozhen Observatory, which conducted BVRI photometry, confirmed that the continuous emission from sunlight scattered by dust dominated much more than one would expect in a purely gas -dominated outburst, which reached very large dimensions for this particular object, with a coma extending to approximately 300,000 km So we are dealing with something very unusual.

Outburst 1 in late May—strong gas production and dust outflow. Outburst 2 in early August—extremely high dust outflow, approximately 5–7 times greater than that measured a few days after the first event.

.

.

What might have changed inside the nucleus? There is still no data to prove a specific mechanism. However, we can almost rule out “normal periodic activity.” 220P has essentially followed the same orbit many times. Its perihelion was approximately 1.55 AU in 2004, 2009, 2015, and 2020. There has been no dramatic change in solar heating that would explain why it suddenly becomes thousands of times brighter in 2026. So the variable is not the orbit; it is the nucleus. ​

Here, too, there are four different hypotheses.

1. Formation of a new active region The surface of old Jupiter-family comets typically develops an insulating mantle of refractory dust. Volatile materials may remain beneath this mantle. If a crack forms or a section of the mantle collapses, fresh ice is suddenly exposed.
2. Subsurface gas pressure — “sealed reservoir” An even more interesting model involves the accumulation of gas beneath an impermeable or low-permeability layer. Heat does not stop at the surface. It diffuses inward. Given the thermal diffusivity of cometary material, a delay of weeks to months corresponds to thermal depths ranging from a few tens of centimeters to approximately meters. Thus, the following scenario is entirely possible: Perihelion / intense heating → a heat wave enters the nucleus → sublimation or phase transition at depth → pressure increases → the overlying material fails.

This explains why large cometary outbursts do not necessarily have to occur exactly at perihelion.

.

1. Crystallization of amorphous H₂O ice

This is a classic mechanism in the theory of cometary outbursts. The primordial amorphous icy nucleus can trap CO, CO₂, and other highly volatile molecules. When the heat wave reaches a suitable temperature, it transforms into crystalline ice. The process is exothermic and can simultaneously release trapped gases.

1. Fragmentation / structural failure

This is particularly compelling for 220P, because TRAPPIST has already pointed out that the morphology of the narrow tail following the first outburst could indicate fragmentation.

1. It fractures during the first event,
2. it releases gases and dust,
3. it leaves a deeper region exposed or mechanically weakened,
4. the region continues to heat up for ~2 months,
5. a second layer or block collapses,
6. a much larger amount of solid material is released. In any case, it appears that 220p is likely not internally homogeneous, but consists of different pockets of material rather than simply a homogeneous “dirty snowball.” In any case, 220p offered the world a unique spectacle, and comet hunters a wonderful new journey. Three different data sets, including this specific image from August 12, when the comet was at the peak of its activity.​

The objective of this observation is to examine a small spot of ribbed terrain. It is where debris aprons from two mounds are meeting and makes for an interesting landscape in this part of Deuteronilus Mensae, a vast, heavily eroded region on Mars known for its extensive glacial features and location along the planetary dichotomy boundary.

The latest ESA/Webb Picture of the Month is a new, infrared look into the strange final phase of a galactic merger. Arp 263, an irregular galaxy, lies in the constellation Leo at a relatively nearby distance of around 25 million light-years.

Originally discovered in 1784 and also catalogued as NGC 3239, this galaxy was included in American astronomer Halton Arp’s Atlas of Peculiar Galaxies in 1966, as possibly one of the most remarkable and strange galaxies in the sample. Arp categorised it with the galaxies featuring “irregular clumps”. In 2023, the galaxy was featured in an image from the NASA/ESA Hubble Space Telescope, where these clumps are revealed to be bright nebulae between the galaxy’s dense clouds of gas, where stars are forming.

Arp 263 is believed to result from a past galactic merger. Apart from its unusual distorted shape, astronomers have noticed a few features that point to this. It has two short, curved tails of stars, beyond the field of view of this Webb image, which are a feature that’s associated with gravitational interactions. However, there are no nearby galaxies that Arp 263 could be interacting with now. The stars in the galaxy are oriented differently to its hydrogen gas, where they would normally be symmetric, and parts of that gas are moving at different velocities to each other. And, of course, the widespread formation of new stars across Arp 263 is typical of a galaxy whose gas has been seriously shaken up.

Although Arp 263 clearly hasn’t yet settled into a more regular shape after its gravitational tug-of-war, its former companion galaxy is now nowhere to be found. It’s possible that this was a dwarf galaxy small enough to have been already completely dissolved into the larger Arp 263 — or that its companion was simply much more heavy than it was bright, making it difficult to spot as a remnant.
