- Webb and Hubble Map Far-Flung Solar System Objects — NASA
Combined observations from the James Webb Space Telescope and Hubble examined some of the smallest and faintest trans-Neptunian objects yet detected. The data showed fewer small objects than models predicted. Colors of these distant bodies followed the same patterns seen in larger members of the population. Researchers noted the relationships held across size ranges, suggesting formation processes preserved early solar system conditions. The study marks the first time both telescopes were used together on this population. Source: science.nasa.gov - Stoke Space Reveals Block 2 NOVA Rocket Design — Everyday Astronaut
Stoke Space announced the Block 2 version of its NOVA rocket, with scaled-up propellant tanks and engines. The design increases payload capacity while retaining full reusability features. Engineers reported the vehicle will support higher flight rates through simplified manufacturing. A detailed technical breakdown was released alongside the announcement.

The Hubble Space Telescope imaged nebula N44, highlighting a central superbubble spanning roughly 210 by 140 light-years. The cavity formed by stellar winds and supernovae from young massive stars. Dense shells of gas and dust surround the void, creating sites for new star formation. The image is available for download in multiple resolutions.

The Avanti Communications Hylas 2 satellite started moving again in July 2026 after earlier shifts from 31E to 142E in 2024 and then to 72.5W in early 2025. Orbital tracking shows the spacecraft continues to change longitude. No official reason for the repeated moves has been released.

The Curiosity rover passed the 1-kilometer elevation mark above its landing site while climbing Mount Sharp. The milestone occurred during sols 4995-5001. Team members documented how the rover has become a capable mountaineer over its extended mission. Planning for the next phase of layered rock analysis continues.

Observations show certain supermassive black holes accrete mass faster than their host galaxies form stars. Most galaxies host a central black hole that grows in step with the surrounding stellar population. The new findings indicate the two do not always evolve at the same rate. Data come from surveys tracking active galactic nuclei across cosmic time. Source: phys.org - Hayabusa2 Completes First Asteroid Laser Ranging — Universe Today
JAXA’s Hayabusa2 spacecraft performed the first successful laser ranging experiment during a flyby of an asteroid on July 5, 2026. The instrument measured precise distances while the probe passed the target. Results confirm the technique works at asteroid distances. The test opens new navigation options for future missions.

SpaceX launched the final satellites needed to finish SES’s O3b mPower constellation. The spacecraft provide high-throughput broadband coverage from medium Earth orbit. The series brings the total number of operational satellites to the planned count. Source: astronomy.com - Astronomers Find Most Distant Galaxy Proto-Supercluster — Phys.org Space
An international team identified the earliest known progenitor of a galaxy supercluster using the ODIN survey. The structure was detected with the Dark Energy Camera on the Víctor M. Blanco Telescope. Its distance and mass support models of how clusters assemble within the cosmic web. The discovery adds a key early data point to structure-formation studies.

Researchers propose Venus once possessed a moon that later spiraled inward and was destroyed. The scenario explains why Venus lacks a natural satellite today despite forming in a similar environment to Earth. Dynamical simulations show tidal interactions could drive such an outcome. The idea remains under active modeling. Source: space.com - Icy Exocomets Detected Around Young Star PDS 70 — Universe Today
Astronomers at Lund University found evidence of exocomets orbiting the young star PDS 70. The comets appear to deliver water ice to the inner regions of the system. Observations link the activity to processes that may have supplied Earth’s oceans. The system offers a direct analog for early solar system conditions.

Fast radio bursts passing through galactic halos and the intergalactic medium show dispersion that reveals gas density. The brief flashes travel billions of light-years, accumulating delays proportional to the amount of matter encountered. Researchers are testing whether the bursts can separate feedback effects from dark matter distributions. Source: phys.org - Giant Impacts Can Remove Subsurface Oceans — Phys.org Space
Simulations at Southwest Research Institute show that large collisions can strip icy moons of existing subsurface oceans. The models indicate impacts do not generate new oceans but can destroy or thin older ones. Results apply to moons in the outer solar system that experienced early bombardment.

University of Mississippi researchers are testing methods to convert Martian air into methane with reduced unwanted byproducts. The process targets in-situ propellant production for return trips. Early lab results focus on catalyst efficiency under simulated Martian conditions. Source: phys.org - New Clues Emerge on Moon Formation Timing — Universe Today
Updated impact simulations examine how temperature and material strength during the giant impact shaped the Moon’s isotopic match with Earth. The models explore whether the collision could have produced the observed compositions in hours rather than longer timescales. Source: universetoday.com
Cosmic Spotlight
The ODIN survey’s detection of the most distant galaxy proto-supercluster relied on narrowband imaging that isolates Lyman-alpha emission from forming galaxies. This technique picks out structures still assembling when the universe was less than two billion years old. The find strengthens the picture that the cosmic web’s largest knots began growing very early. It also supplies a benchmark for simulations that must now reproduce such massive overdensities at high redshift. How many more of these seeds remain hidden at even greater distances?
Cosmic Deep Dive: Black Hole Growth Outpacing Host Galaxies
Picture a city whose downtown core gains new residents ten times faster than the surrounding suburbs expand. That is the scale difference astronomers now measure in some galaxies: the central black hole can double its mass while the galaxy’s stars increase by only a modest fraction. The mechanism begins when large reservoirs of cold gas lose angular momentum and funnel inward, feeding the black hole at rates far above what star formation consumes. Observations show these episodes can last tens of millions of years, enough time for the black hole to reach billions of solar masses while the galaxy’s stellar disk grows more slowly. One surprising number stands out: in the most extreme cases the black hole’s accretion luminosity exceeds the entire galaxy’s starlight output by factors of several. Yet the trigger that lets so much gas reach the center without first turning into stars remains unknown. We can map the final mass ratios, but nobody yet knows why the gas sometimes bypasses star formation so efficiently.
Space keeps turning up surprises that rewrite how we picture the universe’s assembly. |
