We report the discovery and characterization of TOI-6692 b, an eccentric (e ∼ 0.54) Jupiter on a 130 day orbit. TOI-6692 b was first detected as a community TESS Object of Interest by the Visual Survey Group and the Planet Hunters group as a single-transit candidate via TESS observation. The period was subsequently confirmed via radial velocity

4U 1700─37 is a wind-fed high-mass X-ray binary comprising a compact object, most likely a neutron star, accreting from the O6.5 Iaf + supergiant HD 153919. Coherent pulsations have not been firmly detected and the magnetic field strength remains uncertain, with previous NuSTAR studies reporting only marginal candidate cyclotron resonant scattering

As the diversity of exoplanets continues to grow, it is important to revisit assumptions about habitability and classical habitable zone definitions. In this work, we introduce an expanded 'temperate' zone, defined by instellation fluxes in the range $0.1< S/\mathrm{S}_{\oplus }< 5$, thus encompassing a broader range of potentially habitable worlds

To investigate the formation and evolution of vertical structures in disk galaxies, we measure global sech 2 scale heights, averaging thin and thick components when present, for 2631 edge-on disk galaxies with M * > 10 10M ⊙ at 0 < z < 3.5 from the JWST COSMOS-Web survey. We show that dust extinction systematically overestimates scale heights at

Aims. In this work, we exploit the most robust, old, and cosmology-independent age estimates of individual stars from Gaia DR3 to place a lower bound on the age of the Universe, t U. These constraints can be used as an anchor point for any cosmological model, thus providing an upper limit to the Hubble constant H 0. Methods. Our primary stellar age

ASASSN-24fw, monitored by the All-Sky Automated Survey for SuperNovae, underwent a rapid and deep dimming event beginning in late 2024 and lasting until 2025 June. The pre-dimming spectral energy distribution indicates that ASASSN-24fw is an F-type main-sequence star with a persistent infrared excess, corresponding to a fractional luminosity of
