ESO FINDS A MOON WITHOUT A PLANET

  • ESO's Very Large Telescope detected evidence for a moon-like object in the CD-35 2722 system that orbits a brown dwarf rather than a planet, blurring the line between moons and sub-stellar companions and prompting a debate over classification.

WEBB PROBES LITTLE RED DOTS

  • NASA's James Webb Space Telescope has investigated the "family tree" of Little Red Dots — extremely distant, compact red sources first found in 2022 — testing whether they are dust-shrouded active galactic nuclei, compact starbursts, or a mix of both.

PSYCHE GRAVITY ASSIST AT MARS

  • NASA's Psyche spacecraft completed a Mars gravity assist flyby, as captured in imagery released July 29, 2026, using the Red Planet's gravity to bend its trajectory toward the metal-rich asteroid 16 Psyche.

INTERSTELLAR COMET 3I/ATLAS CHEMISTRY

  • ESO's VLT measured the chemical fingerprints of interstellar comet 3I/ATLAS — the brightest interstellar object ever observed — in the first spectroscopic composition study of a comet formed outside the Solar System, suggesting it is older than the Sun.

  • NASA's Nancy Grace Roman Space Telescope Wide Field Instrument (WFI) is fully assembled and undergoing environmental testing, with infrastructure pages detailing the dual-band high-gain antenna (S-band 2 GHz uplink, Ka-band 26 GHz downlink at 500 Mbps) and the six-panel Solar Array Sun Shield now published.

ISS EXPEDITION 75 SPACEWALK PREPS

  • The seven-person Expedition 75 crew aboard the International Space Station spent July 29 training for upcoming spacewalks while conducting futuristic exercise protocols, advanced ocular exams, and virtual reality research sessions.

☀️ SPACE WEATHER

NOTE: The most recent NOAA SWPC alerts in the dataset date from mid-to-late July 2026. No alerts within the past 24 hours (July 30 UTC) appear in the data. Reporting the most recent notable events for situational awareness.

RECENT ACTIVITY SUMMARY

  • The most significant recent event was a NOAA G3 Strong geomagnetic storm on July 4, 2026, when the K-index reached 7; an X1.3 solar flare (R3 Strong radio blackout) also erupted at 20:41 UTC that day from active region N15W75.
  • An M5.5 flare (R2 Moderate) fired from N15W87 on July 5, 2026 at 17:57 UTC, accompanied by a Type II radio emission implying a CME shock at roughly 959 km/s.
  • An M6.3 flare (R2 Moderate) from S06W46 peaked July 3, 2026 at 18:59 UTC, producing a 10cm radio burst peaking at 780 solar flux units.
  • A K-index of 4 (G1 minor) geomagnetic warning was issued July 22, 2026, with a 10cm radio burst peaking at 200 sfu recorded earlier that day.
  • Current conditions: no active high-level SWPC alert is present in the dataset for July 30-31, 2026; solar activity appears to have quieted from the early-July active period.

📄 RESEARCH

SOLAR ENERGETIC PARTICLES AND CME SHOCKS

  • A new review on arXiv covers Solar Energetic Particles spanning a few keV to several GeV, tracing their acceleration at solar flare sites and shock waves driven by Coronal Mass Ejections — key reading for understanding radiation hazards in deep space.

INTERSTELLAR ROUTE TO AMINO ACIDS

  • Researchers describe an energetic, non-aqueous interstellar pathway by which alpha-amino acids such as glycine — already detected in meteorites and comets — could form in space ice without liquid water, strengthening the case for an extraterrestrial origin for prebiotic chemistry.

MYSTERIOUS CLUMPS IN THE AU MIC DEBRIS DISK

  • Modelers propose that an inclined, eccentric planet combined with an inner debris disk could simultaneously explain the fast-moving clumps flying outward on the southeast side and the inward-moving bright features on the northwest side of the AU Microscopii disk — a long-standing puzzle around this young M star.

ORBITAL HISTORY OF SUNGRAZING COMET C/2026 A1 (MAPS)

  • A computational study integrating the orbit of Kreutz sungrazer C/2026 A1 (MAPS) back to the 4th century, including 1,000 virtual clones, finds a plausible orbital link to daylight comets recorded in AD 363, suggesting this comet may be part of a historically documented fragmentation chain.

NEUTRINO FOSSILS IN ANCIENT MINERALS

  • Researchers investigate using ancient minerals as "paleodetectors" to find nuclear recoil tracks left by neutrinos from past Galactic core-collapse supernovae over millions of years, accounting for failed supernovae and varying neutron star masses as a new window into Galactic stellar death.

PARKER SOLAR PROBE CATCHES STREAM ACCELERATION

  • Analysis of Parker Solar Probe and Solar Orbiter data finds direct evidence that a corotating solar wind stream transfers energy from turbulent fluctuations back into the bulk plasma flow at heliocentric distances between 15 and 120 solar radii, offering new insight into solar wind heating.
