⚡ TL;DR
NASA confirms Elias 2-24 b as the youngest known planet at under one million years old, rewriting planet-formation timelines. A busy week ahead: Starship Flight 14 targets Sept. 22, geomagnetic unrest continues through Sept. 17, and Roman's Wide Field Instrument is now live.

CASC has two late-September vehicles on the manifest: Long March 8A and Long March 12A Flight 2 (second test of that new rocket), both targeting Sept. 30 with payloads TBD. [7] [8]
Rocket Lab Electron will fly NASA-sponsored LOXSAT 1, a cryogenic oxygen fluid-management demo on a Photon-LEO bus developed by Eta Space, targeting Sept. 30 TBD. [9]
SpaceX Falcon 9 will launch the SDA Tranche 1 Transport Layer A — part of the U.S. Space Force's Proliferated Warfighter Space Architecture — also targeting Sept. 30 TBD. [10]
🔭 DISCOVERIES
RECORD-BREAKER: Astronomers using NASA-funded archive data have confirmed Elias 2-24 b as the youngest known planet, clocking in at under one million years old and still embedded in its natal dust-and-gas disk — straining existing planet-formation models.
ESA's Webb telescope released one of its largest images to date: a sweeping panorama of star-forming region IC 348, in which astronomers found brown dwarfs just twice the mass of Jupiter, pushing the lower boundary of brown dwarf masses.
ESA's longest-ever satellite ice-sheet record reveals Greenland and Antarctica have shed 11 trillion tonnes of ice since the 1970s, lifting global sea level by more than three centimetres, with glacier acceleration as the dominant driver.
NASA's Astronomy Picture of the Day today features Webb's infrared view of M64, the "Black Eye Galaxy," highlighting dust-lane structure in new detail.
Mars Express imagery of an ice cliff near Mars's south pole shows striking purple, pink, and red swirls — color variations driven by layered dust and ice composition differences.
NASA's Curiosity rover passed its 5,000th Martian day (Sol 5000) parked at a sand ridge called "Chocolatal," capturing a black-and-white panorama at dawn (Aug. 30) and dusk (Sept. 2) local Mars time.
🛰️ MISSIONS
NASA's Nancy Grace Roman Space Telescope team successfully activated the Wide Field Instrument — a 300-megapixel infrared camera — and also checked out the Coronagraph Instrument, Roman's direct planet imager.
Artemis III crew members NASA astronaut Randy Bresnik and ESA astronaut Luca Parmitano visited Kennedy Space Center's Vehicle Assembly Building on Sept. 2 to inspect solid rocket booster integration in High Bay 3.
Artemis II commander Reid Wiseman will appear at the Baltimore Ravens vs. New Orleans Saints NFL game on Sept. 20 as part of NASA's new Inspiration Tour, aimed at showcasing U.S. space and aeronautics capabilities.
JAXA's Martian Moons eXploration (MMX) spacecraft has a confirmed launch aboard H3 Launch Vehicle Flight 10 (H3 F10), as announced Aug. 20.
NASA's Guam Remote Station — devastated by Super Typhoon Mawar in 2023 — was fully restored and celebrated with a ribbon-cutting Sept. 10, completing a three-year rebuild by agency engineers.
NASA test pilot Mike Lippert powered up the X-59 quiet supersonic aircraft's cockpit for the first time this summer, running engines on the ground in a key training milestone ahead of first flight.
NASA field-tested a three-robot AI fleet at an analog exploration site, assessing the fleet's ability to operate as an autonomous science team for future planetary exploration missions.
☀️ SPACE WEATHER
ACTIVE NOW: NOAA issued a K-index 4 extended warning valid through Sept. 16 18:00 UTC, and a K-index 5 (G1 Minor) warning valid from Sept. 15 18:55 UTC through Sept. 16 06:00 UTC — both currently in persistence-mode.
A NOAA G1 geomagnetic storm watch is in effect for Sept. 16 and Sept. 17, with conditions forecast to drop below G1 by Sept. 18.
Context: A G1 event on Sept. 8 reached K-index 5 twice and briefly prompted a G2 (Moderate) watch for Sept. 9; an S1 Minor solar proton event (10MeV flux 18 pfu peak) was recorded Sept. 5 from the same active region.
Operators of LEO satellites and high-frequency radio users at high latitudes should remain alert through Sept. 17 as the current elevated geomagnetic period persists.
📄 RESEARCH
YOUNGEST PLANET PHYSICS: An arXiv study revisiting protoplanetary disk evolution around solar-type stars uses gas kinematics to derive dynamical stellar masses, providing tighter constraints on when giant-planet cores can form — directly relevant to the Elias 2-24 b discovery.
SATURN-CLASS PLANETS ARE THEIR OWN THING: A new paper argues that "inflated giant" exoplanets skew empirical mass-radius relations, causing Saturn-sized worlds to be misclassified as large Neptunes; removing inflated giants sharpens the boundaries between planet classes.
HIDDEN GLOBULAR CLUSTER FOUND: Using Vera C. Rubin Observatory Early Data Preview 2, researchers discovered Rubin-GC1 (Rubin J1628-1735) — a dust-shrouded Milky Way halo globular cluster in the direction of the Galactic bulge in Ophiuchus, hidden by high stellar density and extinction.
GLYCINE IN SPACE — STILL ELUSIVE: A theoretical study finds that glycine's conformational complexity (multiple molecular shapes) has prevented its detection in the interstellar medium despite being present in meteorites and comets; kinetic trapping between conformers at low temperatures may explain the non-detections.
FAST RADIO BURST AT LOW FREQUENCY: Researchers report detection of a fast radio burst from a non-targeted low-frequency radio survey — an exceptionally rare find below 400 MHz that constrains FRB emission mechanisms and source environments.
ASTEROID 2024 YR4 CHARACTERIZED: A thermophysical study combining JWST-NIRCam light curves with ground data constrains the rotation period, spin pole, and shape of the potentially hazardous Apollo-type asteroid 2024 YR4, which makes close Earth-Moon encounters roughly every four years.
COSMIC WEB TURBULENCE MAPPED: The WEFT project (paper I) presents evidence for emerging turbulence in a cosmic filament of the warm-hot intergalactic medium — the reservoir thought to hold the Universe's "missing baryons" — providing the first observational handle on its thermodynamic state.
