Galaxy’s One UI 8.5 adds GUI Linux Terminal and full storage access

Samsung’s Galaxy devices on One UI 8.5 gain a significantly upgraded Linux Terminal that can run graphical Linux apps, shows access to all shared storage folders (DCIM, Movies, Android, etc.), and is operable via ADB commands; the feature aligns with Android 16 QPR2’s graphical-apps support, but enabling Terminal now requires ADB and the Developer Options search for Terminal is removed.

Distant Black Hole Fades in a Human-Scale Timespan

Astronomers tracked galaxy J0218−0036 (about 10 billion light-years away) and found its central supermassive black hole dimmed by about 20x overall and ~50x in the active nucleus from the early 2000s to 2023. Dust obscuration was ruled out, pointing to an intrinsic drop in accretion with the Eddington ratio falling from ~0.4 to ~0.008. The observed e-folding timescale is roughly 2,000 days in the observed frame (~700 days rest frame), far faster than standard models predict, suggesting a change in accretion mode and challenging current black hole growth theories.

Galaxy Phones Gain Direct Satellite Access With App Support

Samsung has published a list of satellite-ready apps that can work on Galaxy devices even without cellular coverage, enabled through carrier partnerships in Europe, Japan, and North America. Galaxy S22+ and newer models generally support direct satellite connectivity (with some markets also supporting select Galaxy A series), and service varies by country. Current satellite-ready apps include Find My Mobile, Google Maps, Google Play Services, WhatsApp, Samsung Account, Samsung Health, Weather, and X (Twitter), among others.

Hubble Spots a Galaxy 99.9% Dark Matter

Astronomers using data from the Hubble Space Telescope, Euclid and the Subaru Telescope identified Candidate Dark Galaxy-2 (CDG-2), a distant galaxy that appears to be about 99.9% dark matter and extremely star-poor. The galaxy’s mass is inferred from a halo of four globular clusters, suggesting a rare, almost-dark galaxy that could provide a cleaner probe of dark matter—though further observations, including with the James Webb Space Telescope, are needed to confirm its dark matter content.

Hubble spots galaxy made almost entirely of dark matter

Astronomers using the Hubble Space Telescope, Euclid, and the Subaru Telescope have identified Candidate Dark Galaxy-2 (CDG-2) in the Perseus Cluster, a galaxy so faint it’s dominated by dark matter—at least 99.9%—with four globular clusters indicating a massive dark halo and little to no starlight. The finding, based on globular clusters around a largely starless galaxy, suggests such dark galaxies may be common and could provide clean tests of dark matter physics; further observations with the James Webb Space Telescope could help confirm its dark matter content.

A Galaxy Nearly All Dark Matter, Revealed by Four Star Clusters

Astronomers have confirmed CDG-2, a faint galaxy in the Perseus cluster detected only through four globular clusters that provide about 16% of its light; by combining data from Hubble, Euclid, and Subaru, they estimate the galaxy’s total luminosity at roughly 6 million suns and a mass composed of 99.94%–99.98% dark matter, making it one of the most dark-matter–dominated galaxies and a valuable natural laboratory for studying dark matter and galaxy formation.

Galaxy Analyst Sees Bitcoin Slipping Below $60K on Weakness Signals

A Galaxy analyst says Bitcoin could fall below $60K due to structural weakness in its price, with on-chain signals and the 200-week moving average pointing to a test of around $58K (and roughly $56K realized price). Absent near-term catalysts, BTC may drift toward the bottom of the supply gap near $70K before probing the $58K–$56K zone; historical drawdowns have often extended losses, though long-term holders could view a potential bottom in the current range as a buying point.

Apple Eyes Stronger iPhone-Galaxy RCS Messaging with End-to-End Encryption

A report suggests Apple is testing a new RCS profile and end-to-end encryption in iOS 26.3 Beta 2 to improve cross-platform messaging with Galaxy devices. RCS Universal Profile 3.0 adds E2EE, plus features like Tapback, inline replies, and edit/unsend, with four French carriers currently showing the code; Apple may also collaborate with Google to boost Android-to-iPhone RCS availability.

Precessing Black-Hole Jets Quench Star Formation in a Merging Galaxy

Astronomers studying the nearby merging galaxy VV 340a detected kiloparsec-scale, precessing jets from its central black hole that heat and eject coronal gas, removing star-forming material at roughly 19 solar masses per year—an unusually large-scale example of black-hole feedback that may suppress star formation, though the merger could later reignite it.

Down in Space Is Relative: Planes, Orbits, and the Cosmic Bearings

Down in Space Is Relative: Planes, Orbits, and the Cosmic Bearings

There isn’t a universal ‘down’ in space. The solar system lies in a flattened disk (the ecliptic) because the collapsing rotating solar nebula shaped planets to orbit in roughly the same plane. The Milky Way has its own galactic plane (tilted about 60° to the ecliptic), and the Local Group sits in a nearly perpendicular supergalactic plane (about 84.5° to the galactic plane). Orientation of these planes comes from the initial rotation of matter when clouds collapsed, so every star, planet, and galaxy can have its own plane and direction depending on where you’re looking.
