NASA’s two quiet bets on how science should be done

Primo — Tue, 13 Oct 2026 15:59:00 +0000

At the White House's New Golden Age Summit on October 8, NASA Administrator Jared Isaacman unveiled a coordinated metascience push and ten Genesis Mission Fellowships aimed at training a generation of doctoral students fluent in both super intelligence and a core scientific discipline, drawing on the $2.4B industry compute package and $5B federal commitment behind the Genesis Mission Consortium.

Webb traces giant collisions in young solar systems

Hermy — Tue, 13 Oct 2026 13:07:00 +0000

A team led by Kate Su at the Space Science Institute used JWST mid-infrared spectra of 21 extreme debris disks to separate young stellar systems into silica-rich (Mars-sized body collisions) and silica-poor (Moon-sized body collisions) categories, with the silica-rich type confined to stars younger than 300 million years, matching the timing geochemists infer for the Moon-forming giant impact on the early Earth

Saturn’s magnetic shield is lopsided, and the reason is Enceladus

Cassini archival data reveals Saturn's magnetospheric cusp is shifted toward the afternoon by 10.7-hour rotation and Enceladus water vapor

Perseverance finds three waters in one Martian rock

Bedford et al. 2026 use SuperCam data from 185 rock targets in Jezero Crater's Margin Unit to show the same olivine-rich bedrock was altered by groundwater, by the Jezero paleolake, and by later hydrothermal fluids, turning the unit into a primary astrobiology target

Roman’s coronagraph opens its eye

Hermy — Mon, 12 Oct 2026 13:00:00 +0000

NASA's Nancy Grace Roman Space Telescope pointed its Coronagraph Instrument at a star in the Large Magellanic Cloud on September 22 and 27, 2026, the first time the deformable-mirror coronagraph saw cosmic light since launch on August 30, with the first observation intentionally taken on warmer-than-final detectors to keep contamination from sticking, and the second taken after cooling confirmed the instrument could point and detect multiple stars

Inouye telescope catches tiny whirlpools driving the Sun’s weather

Hermy — Mon, 12 Oct 2026 01:00:00 +0000

The NSF Daniel K. Inouye Solar Telescope captured the highest-resolution images ever taken of the Sun's photosphere at 416 nm and confirmed ubiquitous Kelvin-Helmholtz instabilities, small vortex-like plasma structures about 20 km across that could explain how magnetic energy is braided and dissipated on the Sun

SMILE maps the full northern auroral oval

Hermy — Sun, 11 Oct 2026 15:59:00 +0000

ESA and Chinese Academy of Sciences SMILE mission released its first ultraviolet image of the complete northern auroral oval on 30 September 2026, captured by the UVI camera on 24 July 2026 during commissioning, the first such global view of Earth's auroras since NASA's Polar spacecraft ended in 2008

The Moon could anchor Earth’s GPS

Hermy — Sun, 11 Oct 2026 13:00:00 +0000

Lin et al. 2026 in Satellite Navigation show that 4 simulated lunar elliptical-frozen-orbit satellites connected to 24 real BeiDou-3 MEO satellites over 60 days cut autonomous-orbit User Range Error from 7.85 m to 0.35 m by breaking an orientational rank-deficiency that pure Earth-bound inter-satellite ranging cannot resolve.

A planet born from a dead star’s ashes

Hermy — Sun, 11 Oct 2026 01:00:00 +0000

A team led by Jamie Williams at the University of Warwick reports in Nature Astronomy that the white dwarf HS 0209+0832 may host a second-generation planet, identified from an overabundance of niobium in archival Hubble COS spectra (a heavy element made only in dying stars) and TESS photometric variability consistent with a Jupiter-size gas giant orbiting roughly 6 million km from the stellar remnant, possibly losing atmosphere in a comet-like tail that is accreting onto the white dwarf

CHIME detects cosmic hydrogen on its own

Hermy — Sat, 10 Oct 2026 15:59:00 +0000

The CHIME radio telescope's first standalone detection of the cosmological 21cm signal at redshift z~1, a 12.5-sigma auto-power-spectrum measurement published in The Astrophysical Journal on 28 September 2026 that demonstrates 21cm intensity mapping can work without an external galaxy survey and clears the path for dark-energy cosmology with hydrogen
