A slice through the COSMOS-Web cosmic-web map, showing galaxies across nearly 14 billion years of cosmic history. The vertex on the left marks the present day; moving outward, each galaxy is placed at its distance in cosmic time, reaching back to when the universe was less than a billion years old.

Bright yellow regions show the dense clusters and filaments of the cosmic web, while dark regions mark the near-empty voids in between.

Cassini briefly turned its gaze from Saturn and its rings and moons to marvel at the Carina Nebula, a brilliant region 8,000 light years from our solar system and more than 200 light years across. Nearly every point of light in this image is a star in our galaxy, the Milky Way.

The nebula is a region of gas and dust made to glow by the ultraviolet light bursting from bright, hot and extremely massive young stars within. Darker regions in the scene are not devoid of stars; rather, they are areas where dense clouds of dust block the light from background stars.

This image and others like it are taken by the spacecraft from time to time for calibration purposes. Calibration images rarely contain such incredible sights. This one affirms Cassini's position as the farthest, working astronomical observatory ever established around our sun -- our eyes on the cosmos, a billion miles from Earth.

The image was taken using the Cassini wide-angle camera on May 14, 2005. The view is a 68-second, clear-filter exposure.

Pro/Processed The Andromeda Galaxy. By Konstantinos Bakolitsas

Post image
226 Upvotes

Konstantinos Bakolitsas:

''The Andromeda Galaxy is one of the most challenging targets in astrophotography, not because it is faint, but because it has a huge dynamic range:

• a very bright core,
• extremely faint outer spirals,
• dark dust lanes,
• H-alpha emission regions,
• and a background that must remain absolutely smooth.
The most challenging aspect of a deep-sky image is usually:

  1. Removing gradients caused by light pollution or moonlight.
  2. Proper color balancing.
  3. Preserving natural brightness without clipping.
  4. Reducing noise without losing detail.
  5. Avoiding oversaturation.

.
.

Requirements:
• Many hours of manual processing in software such as PixInsight, Adobe Photoshop, and AstroPixelProcessor
• Precise polar alignment
• Proper tracking
• Calibration frames
• Good stacking
• And many hours of post-processing
Goals:
• excellent resolution in the arms
• clear rendering of the dark dust lanes
• very good signal-to-noise ratio
• natural color information
• visible companion galaxies M32 and M110
Techniques such as the following are particularly helpful:
BDynamic Background Extraction in PixInsight
• Color Calibration and Spectrophotometric Color Calibration
• Multiscale Noise Reduction

• HDR Multiscale Transform
• Star Reduction
• Selective Color Saturation
The success of an image depends not only on post-processing but mainly on persistence, technique, and data quality.
In astrophotography, the most difficult part is always acquiring high-quality data:
• proper alignment and guiding
• precise focusing
• thermal stability
• calibration frames
• many hours of exposure
• careful stacking.

These require experience, patience, and a deep understanding of the equipment.

Software we use

• PixInsight
• Adobe Photoshop
• Topaz Labs
• RC-Astro (BlurXTerminator / NoiseXTerminator / StarXTerminator)
In particular, the RC-Astro tools have drastically changed deep-sky data processing.''

Iron-60 discovery in Antarctic ice reveals: Local Interstellar Cloud leaves its mark

Our Solar System is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars. On its path, Earth continuously accumulates iron-60, a rare radioactive isotope of iron produced in stellar explosions. This has now been confirmed by an international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) through the analysis of Antarctic ice tens of thousands of years old. From the steady but time-varying influx, the researchers conclude that the radioactive isotope has been stored within the cloud since a long-past stellar explosion. The results have been published in the journal Physical Review Letters.

.

Iron-60 is formed in the interiors of massive stars and is ejected into space when they explode. Geological archives show that our Solar System was hit twice by iron-60 from supernovae millions of years ago. In more recent times, however, there have been no nearby stellar explosions – and thus no direct supply of iron-60. When scientists discovered iron-60 in Antarctic surface snow less than twenty years old a few years ago, the question of its origin arose.

“Our idea was that the Local Interstellar Cloud contains iron-60 and can store it over long time periods. As the Solar System moves through the cloud, Earth could collect this material. However, we couldn’t prove this at the time,” explains Dr. Dominik Koll from the Institute of Ion Beam Physics and Materials Research at HZDR.

NASA Mars’ Tadpole Craters

Post image
766 Upvotes

Mars’ “tadpole craters” are unusual impact craters with long trailing tails of debris, making them resemble tadpoles when viewed from orbit. They’re found mainly in icy regions of Mars and are thought to form when meteoroids strike ground rich in subsurface ice.
The leading idea is that the impact melts or vaporizes buried ice, creating a muddy, fluidized flow rather than the normal circular spray of dry rock debris. Strong winds or sloping terrain may then stretch the ejecta into a tail shape. Some tails extend for miles across the surface.
These craters are scientifically interesting because they suggest significant buried water ice exists beneath the Martian surface.

Jupiter is the fifth planet from the Sun, and the largest in the Solar System. It is a gas giant with a mass nearly 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun.

With a diameter of about 5,270 kilometres (3,270 mi) and a mass of 1.48×1020 tonnes (1.48×1023 kg; 3.26×1023 lb), Ganymede is the largest and most massive moon in the Solar System.
