Both NASA ESCAPADE spacecraft built by Rocket Lab fired engines during an Earth gravity assist and now point toward Mars, with arrival expected in September 2027.
Simulations constrained by 56,229 measured craters give degradation rates for 50–500 m craters on the Moon; small cold traps are short-lived, so their ice is recent.
Astronomers using the Gemini North telescope on Maunakea report a faint, tight pair of quasars, seen as it was during the epoch of reionization.
The model uses Inouye telescope images and scaling laws from near-Earth spacecraft data to estimate how the corona is heated to more than a million degrees.
Researchers ruled out binary black holes of about 10 billion solar masses and above in two distant systems. These are the first gravitational-wave limits for so early an epoch.
The transit chord of TOI-2535b moved off the stellar disk. Per TESS and NEID data, the authors link this to a nearby, mutually inclined planet in resonance.
Analysis of the GW190412 signal constrains the recoil direction of the merged black hole and disfavours kick speeds below 50 km/s, typical for dense globular clusters.
Astronomers from Nagoya and Gifu universities mapped a 26-light-year trail of warmed CO gas at LMC P3, supporting the microquasar model of its gamma-ray emission.
Astronomers confirmed Elias 2-24 b, the youngest exoplanet yet detected in images, in archival Keck II data. It formed faster than traditional models predict.
A theoretical analysis in The Astrophysical Journal shows how a planet's Doppler modulation adds sidebands to a gravitational-wave signal; the method favours massive, long-period planets.
In laboratory shock experiments, different zones of the same grain changed differently at identical pressure, so missing shock features do not rule out past impact exposure.
Authors of the FLIP method report 2–15 times better sensitivity on JWST NIRCam coronagraph data and the first detection of 51 Eridani b at 4.3 μm.
The 2024 first campaign of the ALPS II light-through-a-wall experiment saw no signal, yet the setup set a new sensitivity record for laboratory axion searches.
Mid-infrared JWST spectra of the central 0.1 pc show mildly supersolar abundances and signs of fast shocks in compact gas clumps moving at over 600 km/s.
The isolated cloud shows no stellar counterpart in deep DESI images; according to the authors, its dynamical mass is about 200 times the baryonic mass.
Chinese researchers found γ-Fe, a high-temperature iron phase not previously documented in lunar samples, preserved at ambient temperature as nanoparticles with a magnetic vortex state.
JWST observations of the lava planet TOI-561 b over 37 hours indicate an atmosphere, possibly with reflective silicate clouds on the dayside, according to the authors.
Images from 2025 show a decagonal wave in Saturn's southern jet. It drifts east at 2.5 m/s, and no similar wave had been reported in the southern hemisphere before.
A Leiden University-led team imaged 2.5×2.5 deg² with LOFAR at 0.33″×0.39″ resolution. According to the authors, these are the deepest radio images below 1.28 GHz.
X-ray data suggest the giant star in galaxy NGC 4559, which mimics a supernova about every 113 days, feeds a black hole or neutron star on an elongated orbit.
