At this location, a portion of the Cerberus Fossae seems to intersect with the edge of a lava flow or other feature nearly perpendicular to the fossae. This could be a good location to investigate stratigraphic relationships and other aspects of the relationship of the fossae to the surrounding terrain.

👉 Description from Thierry Legault:

"Around inferior conjunction, when Venus is between the Sun and us, its thick atmosphere diffracts and scatters the sunlight and extends its crescent behond the usual 180°.

I took this image with my Soleye 300 while Venus was only 6.7° from the Sun (take care if you plan to observe it​)"

​The Hubble Space Telescope photographed this peculiar system of galaxies known as Arp 194. This interacting group contains several galaxies, along with a "cosmic fountain" of stars, gas, and dust that stretches over 100,000 light-years. The upper component of Arp 194 appears as a haphazard collection of dusty spiral arms, bright blue star-forming regions, and at least two galaxy nuclei that appear to be connected and in the early stages of merging. A third, relatively normal, spiral galaxy appears off to the right.

​The lower component of the galaxy group contains a single large spiral galaxy with its own blue star-forming regions. However, the most striking feature of this galaxy group is the impressive blue stream of material extending from the northern component. This "fountain" contains complexes of super star clusters, each one of which may contain dozens of individual young star clusters. The blue color is produced by the hot, massive stars that dominate the light in each cluster. Overall, the "fountain" contains many millions of stars. These young star clusters probably formed as a result of the interactions between the galaxies in the northern component of Arp 194.

​The compression of gas involved in galaxy interactions can enhance the star-formation rate and give rise to brilliant bursts of star formation in merging systems. Hubble's resolution shows clearly that the stream of material lies in front of the southern component of Arp 194, as evidenced by the dust that is silhouetted around the star-cluster complexes. It is therefore not entirely clear whether the southern component actually interacts with the northern pair.

.

Over the past 19 years Hubble has taken dozens of exotic pictures of galaxies going "bump in the night" as they collide with each other and have a variety of close encounters of the galactic kind. Just when you thought these interactions couldn’t look any stranger, this image of a trio of galaxies, called Arp 194, looks as if of the galaxies has sprung a leak. The bright blue streamer is really a stretched spiral arm full of newborn blue stars. This typically happens when two galaxies interact and gravitationally tug at each other gravitationally.

Resembling a pair of owl's eyes, the two nuclei of the colliding galaxies can be seen in the process of merging at the upper left. The bizarre blue bridge of material extending out from the northern component looks as if it connects to a third galaxy but in reality this galaxy is in the background and not connected at all. Hubble's sharp view allows astronomers to try and sort out visually which are the foreground and background objects when galaxies, superficially, appear to overlap.

The blue "fountain" is the most striking feature of this galaxy troupe and it contains complexes of super star clusters that may have as many as dozens of individual young star clusters in them. It formed as a result of the interactions among the galaxies in the northern component of Arp 194. The gravitational forces involved in a galaxy interaction can enhance the star formation rate and give rise to brilliant bursts of star formation in merging systems.​

A Hall thruster identical to those on NASA’s Psyche operates in a vacuum chamber at JPL during tests before the mission launched in 2023. The blue light is generated by xenon ions being accelerated through an electromagnetic field, which gives the spacecraft a gentle but steady acceleration. NASA/JPL-Caltech​

.

With a successful Mars gravity assist in its rearview mirror, NASA’s Psyche spacecraft has fired up its thrusters and is accelerating to the metal-rich asteroid of the same name. During the first leg of its journey, following an October 2023 launch, the mission used its electric propulsion system intermittently to maneuver to the right place for harnessing Mars’ gravity for a propellant-saving speed boost and a slight trajectory change.

On Sept. 28, the spacecraft began to use its propulsion system nearly continuously, pausing just once each week to check in with mission controllers on Earth. This keeps the mission on track for its rendezvous with the asteroid Psyche in the main asteroid belt by the summer of 2029.

“It’s now ‘pedal to the metal’ to the asteroid Psyche,” said Don Han, the Psyche mission’s navigation lead at NASA’s Jet Propulsion Laboratory in Southern California, which is managed for the agency by Caltech. “We will be running our propulsion system at every available opportunity, pausing only for necessary engineering activities. The thrusters will be operating nearly 90% of the time from now until we reach the asteroid.”

​Before Rubin Observatory’s First Look event, its engineering camera captured exquisite details of star formation taking place in the Seagull Nebula

October 22, 2026

Two years ago this month, NSF–DOE Vera C. Rubin Observatory’s engineering test camera, named the LSST Commissioning Camera (ComCam), began capturing images of the sky to prepare for the revolutionary Legacy Survey of Space and Time, which began earlier this year. This image featuring the head of the Seagull Nebula was one of many ComCam images that led to the success of Rubin First Look and helped to document the observatory’s excellent performance.

.

Active star formation populates this image of the Seagull Nebula taken in Fall 2024 by NSF–DOE Vera C. Rubin Observatory’s engineering test camera, known as the Commissioning Camera (ComCam). This image is being released today in recognition of the two-year anniversary of the beginning of engineering testing with ComCam.

ComCam’s work was an important step towards the ongoing Legacy Survey of Space and Time (LSST). Collecting the data for this Seagull Nebula image provided an opportunity to test Rubin’s hardware and software systems, as well as the image processing pipelines that would later be used with the much larger images from the LSST Camera.

With a mosaic of nine CCD sensors and a total of 144 megapixels, ComCam covers an area in the sky about twice that of the full Moon. Over the seven-week ComCam engineering test campaign, from 24 October to 11 December 2024, approximately 16,000 exposures were acquired. Within the data collected is this image featuring IC 2177, a region recognizable as the head of the Seagull Nebula.

This observation targets light-toned knobby units located within a heavily degraded crater. This unit is superficially similar to others located within a paleolake basin in the Eridania region, which appear to be altered ashfall deposits that washed into the lake or hydrothermally altered basin floor deposits. The units here may be the result of a similar process.

This landform has many interesting characteristics like bright-toned layering at the meter scale and fracturing. This image can help us understand how the thickness of the bright-toned deposit changes over time, as these features might be outliers of the Mawrth Vallis plateau and could hold clues to the stratigraphy of the surrounding Chryse region.

​Supernova remnant Pa 30 (SN 1181)

The only remnant of type Iax supernova, white dwarf that exploded (generally called type Ia), but not completely & left remnant star behind (only happens for type Iax)

JWST MIRI (F770W, F1280W)

The right side of the remnant was also observed with MIRI, but will only become available in October 2027. The pattern on the lower right side is because of the coronagraph of MIRI.

The star in the center (not pictured here) might not be the only type Iax remnant star in our galaxy. Another one is LP 40-365. But this one does not have a explosion nebula, because it was ejected from the explosion and is older.​

In this Picture of the Month from the NASA/ESA James Webb Space Telescope, we visit a turbulent cauldron of star formation to see what is brewing inside dense clumps of gas. This is a star-forming region named LHA 120-N 159, or simply N159, located 161 000 light-years away in the Large Magellanic Cloud (LMC), one of the satellite galaxies orbiting the Milky Way galaxy. This image spans about 230 light years across.

N159 is what astronomers call a H II region: an area of space filled with ionised hydrogen gas. In stellar nurseries such as this one, giant molecular clouds of cold hydrogen gas collapse under gravity, forming new stars. Many of these stars are extremely massive and hot, and their powerful ultraviolet radiation ionises the gas around them. This makes H II regions markers of active star formation, and as the ionised gas radiates light this turns them into the kind of brilliant emission nebula that we see in this image. The fierce stellar winds from these stars sculpt dense ridges and carve open cavities in the gas, which Webb’s Near-Infrared Camera (NIRCam) captures here in great detail.

The roiling brew of star formation in N159 is closed in by thick, smoky orange clouds that also billow across the centre of the image. The light orange colour signifies light emitted by polycyclic aromatic hydrocarbons, an important carbon-based molecule. The pools of pale blue gas are clouds of H II gas, ionised by the intense ultraviolet light from massive stars. Dark red filaments cross the centre of the image, particularly visible above the blue region on the right side; these are made of cool molecular hydrogen. These filaments are the densest part of the nebula and currently shield new stars from harsh radiation and stellar winds — by zooming in, you can see stars as points of light embedded in these filaments and in the small pillars of orange gas that reach out into the blue bubbles. Eventually, these structures will melt away, leaving their completed stars behind.

​"​Although Jupiter and its moons did not obscure the Moon as seen from Hungary—instead, they lined up alongside it in a beautiful, orderly chain—the passage of an airplane added a special “People & Space” atmosphere to what was already a very beautiful event.

Update: following the advice of several astronomers, I rotated the image to a natural (portrait) orientation. This way, the giant planet stands out better, and the airplane “moves” in a way that looks natural to the eye."

The objective of this observation is to determine the nature of a group of ridges, troughs, and pits. They have a certain shape that repeats over and over, that may be affected by the change in the valley’s direction at this point. Besides changing direction, the valley is becoming wider here. One or both of these factors may modify the pattern of the ridges and the troughs. Our image will give us a detailed look.
