The Astrophysical Journal is a peer-reviewed scientific journal covering astronomy and astrophysics. It was founded in 1895 by the American astronomers George Ellery Hale and James Edward Keeler. It publishes three 500-page issues per month. Since 1953, The Astrophysical Journal Supplement Series has been published in conjunction with The Astrophysical Journal. It aims to supplement the material in the journal. It publishes six volumes per year, with two 280-page issues per volume. The journal and the supplement series were both published by the University of Chicago Press for the American Astronomical Society. In January 2009 publication was transferred to Institute of Physics Publishing, following the move of the society s Astronomical Journal in 2008. The reason for the changes were given by the Society as the increasing financial demands of the Press. The Astrophysical Journal Letters is another section of The Astrophysical Journal intended to publish rapid communications.
Astrophysicists studying a popular exoplanet in its star's habitable zone have found that electric currents in the planet's upper atmosphere could create sufficient heating to expand the atmosphere enough that it leaves the ...
The cosmic optical background (COB) is the visible light emitted by all sources outside of the Milky Way. This faint glow of light, which can only be observed using very precise and sophisticated telescopes, could help astrophysics ...
An open question among the physics community is whether black holes can be tidally deformed by an external gravitational field. If this were confirmed to be true, it could have important implications for many areas of physics, ...
A team of astronomers and citizen scientists has discovered a planet in the habitable zone of an unusual star system, including two stars and potentially another exoplanet.

By analyzing the data from ESA's Gaia satellite, Chinese astronomers have detected a new tidal stellar stream in the northern hemisphere, which has a low metallicity and a relatively high energy. The finding was reported ...
An international team of astronomers and astrophysicists has confirmed the first known observance of a tidally locked super-Earth exoplanet. In their paper published in The Astrophysical Journal, the group describes the unique ...
A new investigation into an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, has revealed that these objects are not entirely what they seem. CSOs are active galaxies that host supermassive black holes ...

Scientists studying sunspots have found important clues about magnetic features in their decay that will help understand the evolution and real origin of these mysterious magnetic phenomena. The findings are published in ...
On Sept. 5, 2022, NASA's Parker Solar Probe soared gracefully through one of the most powerful coronal mass ejections (CMEs) ever recorded—not only an impressive feat of engineering, but a huge boon for the scientific community. ...
