NASA’s Webb Provides Crash Course on Planet-Shattering Collisions

October 01, 2026
Artist’s concept of a star and its debris disk against the black background of space. The star is in the background, right of center, and depicted as a small, luminous sphere. The debris disk is a large blue ring that encircles the star. The debris disk is angled toward the viewer, so that the portion nearest to the viewer extends beyond the bottom frame of the illustration. Many dark, rocky fragments are scattered throughout the debris disk. In the foreground, toward the left, is a small planetary embryo colliding into the left side of a larger spherical object. The impact site glows bright yellow and orange and has a mottled appearance, as though chunks of both colliding bodies are breaking up and being destroyed. Orange-yellow streams of vapor extend outward from the collision area. Behind the debris disk and its star are many small stars in the background. A label in the bottom right corner reads “Artist’s Concept.”

In the early history of our Solar System, a Mars-sized object called Theia smashed into the infant Earth, vapourising massive amounts of rock and blasting it into space. Some of that material coalesced into the Moon. Astronomers have now used the NASA/ESA/CSA James Webb Space Telescope to examine a class of young stellar systems that show signs of similar upheavals, providing clues to the amount of energy in their collisions. The results offer insights into the composition and evolution of these chaotic systems.

This NASA/ESA/CSA James Webb Space Telescope Picture of the Month features galaxies in incredible detail that have been warped and multiplied like they’ve stepped into a house of mirrors. The brilliant golden galaxies splashed across this image belong to a galaxy cluster called MACS J0454.1-0300. The orange galaxies concentrated on one side of the cluster are not actually part of the cluster; these galaxies are much farther away from us than the galaxies that make up MACS J0454.1-0300. MACS J0454.1-0300 is itself incredibly distant: the light from these galaxies has been travelling to us for so long that we’re seeing the cluster as it was when the Universe was about 8 billion years old. While this galaxy cluster is a valuable scientific target in its own right, the real stars of this image are the galaxies that appear warped and stretched, like a painting that has been smeared by a …

On Feb 6, 2026, NASAs SPARCS Mission returned first images of an exoplanet, HD 71262, in both, near-UV and far-UV. SPARCS' mission is for monitoring flares and sunspot activity on low-mass stars about 30% to 70% the mass of the Sun which are likely to host rocky planets inside their habitable zones.

AR4366 stands out as the most active sunspot of early 2026, producing an extraordinary sequence of high‑energy flares and posing meaningful space‑weather risks as it faces Earth. Its behavior is characteristic of a highly unstable, rapidly evolving magnetic system capable of generating the strongest solar eruptions of the cycle. Ø71mm APO, IMX178 camera.

1. This web site is target of "Distributed Denial of Service (DDoS)" attack intended by criminals to exhaust the resources of a hosting server. It is a high frequency random access to all web files in the site directory, a classic tactic, aiming to degrade or crash hosting infrastructure. This website is the entry point, but the real goal is to overwhelm the web server or shared hosting environment. Most of the attacking IP addresses originate in the PRC, either on purpose to blame China or it is real. My provider, Hostgator, does not seem to be interested in deeper investigation, instead suggesting the service of "Cloudflare". Even if the contents of the site isn't sensitive, the attack is criminal calling for harsh punishment. This attack also falsifies the visitor access log, wondering what this human garbage is trying to accomplish besides display of sick brains.
2. Certain people appear to enjoy filling forms with random letters for no purpose but insane self-satisfaction. Most of this stupid folks leave their IP addresses which are forwarded to their provider companies. All so received forms are automatically deleted. Sadly, the world is overfilled with idiots, trolls and criminals. This is a public web site without any sensitive data. No need for these irrational displays.

Alphard (30 Alp Hya) in Hya [HIP 46390]

Alphard is the primary star in Hydra. Its excess of barium assumes a white dwarf companion, but is not confirmed. Alphard represents the State of Mato Grosso do Sul on the flag of Brazil.

Distance: 20 light-years, Magnitude: 12
Gliese 268 is a RS CVn-type variable tending to be a binary star system with a strong magnetic field influenced by each star's rotation, which is accelerated by the tidal effects of the other star in the system. Gliese 268 is binary composed of two M-type red dwarfs.

Pyxis is the northernmost constellation separated from the former constellation Argo. Featureless and consisting solely of dim stars, Pyxis is best found in late winter nights and evenings in spring by way of looking from Canis Major to Puppis. Pyxis is Latin for a mariner's compass, unlike Circinus, which is Latin for a draftsman's compass.
Star Chart46P/Wirtanen

Discovered on January 17, 1948, 46P/Wirtanen is a short period (5.4 years) returning comet belonging to the Jupiter family of comets with an estimated diameter of 1.2 kilometers. It boasts a higher level of activity than expected for its nucleus size and emits more water vapor than it should. It was the original target for ESA's Rosetta spacecraft which missed the launch window and changed its destination to 67P. On December 16, 2018 the comet will pass Earth at about 30 lunar distances reaching a forecast magnitude peaking at 3.0 during the close approach or 7.5 visually in a worst case.
Thetis (Asteroid)
Semi-major: 2.47145 AU, Size: 90 km

Discovered on April 17, 1852 by R. Luther, Thetis is a S-type main belt asteroid with both low and high calcium forms of pyroxene on the surface, along with less than 20% olivine. Thetis rotates around its axis in 12.27 hours and has a mass of 1.2x1018kg.
Phoebe (moon of Saturn)

Discovered in 1899, roughly spherical Phoebe is a moon of Saturn showing a heavily scarred surface with craters up to 80 km across. Phoebe is a captured centaur from the Kuiper Belt.
