According to calculations, in a 4-year period researchers may detect of order one compact binary system in which the binary’s inspiral and the spin of its neutron star component both produce gravitational waves.

Unlike traditional “shift and stack” algorithms, a newly developed asteroid-detection method requires no assumptions on speed or direction; this method can be applied to upcoming time-domain surveys.

Researchers show that the global martian dust storm in Mars year 34 warmed the lower atmosphere and led to greater electrical charging and stronger electric fields compared to a dust-free atmosphere.

Researchers show a connection between non-thermal hard X-ray emission and a tadpole-shaped downflow, strengthening the association between these flows and magnetic reconnection.

Spectra of 3I/ATLAS as it retreated from its encounter with the Sun show that the comet’s mixing ratios of CN, C₃, and C₂ with respect to water are similar to those of solar system comets, while NH₂ is depleted.

An analysis of synthetic starspot-crossing events suggests that while starspot longitudes are tightly constrained in high signal-to-noise data, other properties are more loosely determined.

Using data from JWST, the Subaru Telescope, and the Atacama Large Millimeter/submillimeter Array, researchers have identified a previously unseen collimated protostellar jet in a Herbig–Haro object.

Researchers have discovered two chemically distinct populations in a sample of 97 metal-poor stars in the Milky Way halo, potentially providing a way to identify accreted halo stars.

Analysis of blue straggler stars in 56 Milky Way globular clusters finds no evidence for a bimodal distribution in color–magnitude space due to differing formation pathways.

By constructing a detailed distance map to the Magellanic Clouds, researchers have revealed substructures within this interacting galaxy pair, including an azimuthal warp in the Large Magellanic Cloud.

Though the asteroid Apophis will not collide with Earth in 2029, there is a slim but present possibility that it will strike an artificial object orbiting Earth, potentially compromising future missions to the asteroid.

Analysis of 93 stellar halos detected in a sample of 169 high-inclination galaxies showed that high-mass galaxies have more extended halos and more active merger histories, among other findings.

PAN-z14-1 is the fourth most distant galaxy known to date, and its properties are consistent with the emerging picture of two separate galaxy populations at redshifts greater than 10.

Simulations predict that the Roman Space Telescope will discover 33 ± 9 young exoplanets in a one-month survey, expanding our understanding of the properties of planets around very young stars.

Though Type Ic supernovae are classified in part by the lack of helium lines in their spectra, recent modeling of a near-infrared supernova spectrum suggests that helium is present but undetectable in the optical.

Researchers present the first high-resolution multi-wavelength observations of a triple-nucleus merger, showing one black hole with mass of order 100 million solar masses and two with evidence of tidal disruption.

Using the SHAllow RADar split-chirp technique, researchers showed how orbital radar loss estimates could be used to map the composition of Mars’s volcanics on a global scale.

Analysis of JWST and Hubble Space Telescope observations of the galaxy “Eridu” suggests that the galaxy formed within 300 million years of the Big Bang and was quenched by a redshift of z ~ 10.

The combination of data and binary neutron star merger simulations shows that the source of GRB 230307A is unlikely to be a globular cluster; a disk origin is possible but requires finely tuned conditions.

A search for extragalactic exoplanets in data from the Transiting Exoplanet Survey Satellite detected none, but the analysis suggested that investigations of additional stellar streams may find these sought-after worlds.
