New radio observations provide the best view yet of the WISPIT 2 planetary system, revealing spiral wakes driven by a growing ...

New simulations suggest the outer solar system could disassemble within about one billion years after the Sun becomes a white dwarf.

Astrobites reports on the discovery of a new ultra-faint dwarf galaxy in preview data taken before the start of Vera C. Rubin ...

Luckily, one transit astronomer’s trash data can be a pulsation timer’s treasure. For some A-type stars called δ Scuti stars, ...

Wassenius penned a short account of his observations in Latin for Philosophical Transactions of the Royal Society (the longest-running scientific journal in the world!). His drawings of the event, ...

The 58th meeting of the AAS Division for Planetary Sciences will take place 25–30 October 2026 in Spokane, WA. Register today! The American Astronomical Society (AAS) is the major organization of ...

Not all brightness variations present in a star’s light curve are due to stellar variability — instrumental systematics and artifacts from the spacecraft’s orbital period can produce periodic ...

Liu and Wang describe several potential sources of gamma rays in the cocoon — like the massive star cluster Cygnus OB2, the supernova remnant γ Cygni, and a pulsar wind nebula — and demonstrate that, ...

The EHT is a global network of radio dishes stretching from Antarctica to Spain that can be combined to make a planet-size telescope. In April 2017, eight telescopes in six locations around the world ...

In Figure 1, after the stellar mass of the protostellar core exceeds 30 solar masses, we see several pressure-dominated bubbles expanding away from the star (this is most noticeable in the middle row ...

Betelgeuse is a variable star. On top of its well-constrained 400-day pulsation period, the star has exhibited two behaviors that have drawn interest in recent years: a deep, prolonged dimming episode ...
