Comets that have hit Earth have been a mixed bag. Early in Earth's history, during the solar system's chaotic beginning, they were likely the source of our planet's water, ultimately making up about 0.02% of the planet's ...
A study published in Physical Review Letters outlines a new approach for extracting information from binary systems by looking at the entire posterior distribution instead of making decisions based on individual parameters.
Vast, quasi-circular features on Venus's surface may reveal that the planet has ongoing tectonics, according to new research based on data gathered more than 30 years ago by NASA's Magellan mission.

Using a set of ground-based radio telescopes, an international team of astronomers has observed a slowly-spinning pulsar known as PSR J0901−4046. Results of the observational campaign, published on the arXiv preprint server, ...
Using the Spektr-RG (SRG) space observatory, astronomers from the Russian Academy of Sciences have investigated dozens of X-ray sources in all-sky surveys, which resulted in the detection of 11 new active galactic nuclei. ...
An international team of astronomers reports the discovery of two new exoplanets, a few times more massive than Earth, orbiting a sun-like star known as HD 35843. The finding was reported in a research paper published May ...
The universe is decaying much faster than thought. This is shown by calculations of three Dutch scientists on the so-called Hawking radiation. They calculate that the last stellar remnants take about 1078 years to perish. ...

Japanese astronomers have presented new results of observations that suggest an unidentified X-ray source designated AX J145732−5901 is a cluster of galaxies behind the galactic plane. The findings are detailed in a research ...
Astronomers have employed the Nuclear Spectroscopic Telescope Array (NuSTAR) and the Neutron Star Interior Composition Explorer (NICER) to observe the X-ray pulsar RX J0032.9-7348 in a broadband X-ray energy range. Results ...
