Artist’s impression of the HD265435 system at around 30 million years from now, with the smaller white dwarf distorting the hot subdwarf into a distinct…
A star in a distant galaxy blew up in a powerful explosion, solving an astronomical mystery. Dr. Iair Arcavi, a Tel Aviv University researcher at…
Using the Atacama Large Millimeter/submillimeter Array (ALMA), scientists completed a census of nearly 100 galaxies in the nearby universe, showcasing their behaviors and appearances. The…
An international team of astronomers has observed the first example of a new type of supernova. The discovery, confirming a prediction made four decades ago,…

A Smoldering Stellar Corpse on the Edge: Astronomers Spot a White Dwarf So Massive It Might Collapse
This illustration highlights a newfound small white dwarf, discovered by ZTF, that is 4,300 kilometers across, or roughly the size of Earth’s moon, which is…
A red giant star, Camelopardalis, emits a shell of gas as a layer of helium around its core begins to fuse. Such events help scientists…
This illustration depicts a planet partially hidden in the glare of its host star and a nearby companion star. After examining a number of binary…

Time-lapse photograph of the Cosmic Infrared Background Experiment (CIBER) rocket launch, taken from NASA’s Wallops Flight Facility in Virginia in 2013. The image is from…
A team led by UMD astronomers created the first clear image of an expanding bubble of stellar gas where stars are born using data from…
Protoplanetary disks are classified into three main categories: transition, ring, or extended. These false-color images from the Atacama Large Millimeter/submillimeter Array (ALMA) show these classifications…
These images contain two of the star-forming regions of the largest such survey done to date in X-rays by Chandra. The study outlines the link…
Using gas velocity data, scientists observing Elias 2-27 were able to directly measure the mass of the young star’s protoplanetary disk and also trace dynamical…

Artist’s impression of the gas-rich debris disk. Credit: NAOJ A Dutch-led team of astronomers has discovered that high-mass stars are formed differently from their smaller…
Snapshot from the first full STARFORGE simulation. Nicknamed the “Anvil of Creation,” a giant molecular cloud with individual star formation and comprehensive feedback, including protostellar…
Unprecedented high-resolution map of the Orion Nebula Cluster showing newborn stars (orange squares), gravitationally collapsing gas cores (red circles), and non-collapsing gas cores (blue crosses).…
Artist’s conception of a violent stellar flare erupting on neighboring star, Proxima Centauri. The flare is the most powerful ever recorded from the star, and…
“Sound waves trapped inside stars cause them to oscillate at particular frequencies. These vibrations are visible on the surface, and can be measured by astronomers…
