Artist’s illustration of the Local Bubble with star formation occurring on the bubble’s surface. Scientists have now shown how a chain of events beginning 14…
This illustration shows the location of the C-19 stellar stream (orange, vertical stream of stars in lower left), which was recently discovered at the edge…
Coronal rain on the Sun with Earth superimposed for scale. New high-resolution spectrographic observations of a flare on a faint distant star using the Penn…
An image of a galaxy seen face-on in a simulation. It shows the distribution of gas over the galaxy (red is higher density and blue…
A pair of stars at the start of a common envelope phase. In this artist’s impression, we get a view from very close to a…
These annotated images, obtained with the GRAVITY instrument on ESO’s Very Large Telescope Interferometer (VLTI) between March and July 2021, show stars orbiting very close…

This image shows the most massive planet-hosting star pair to date, b Centauri, and its giant planet b Centauri b. This is the first time…
Roasted and Shredded by a Stellar Sidekick: Astronomers Find White Dwarf Blasting a Companion Object
Observations from Chandra reveal unusual X-ray activity from the white dwarf star called KPD 0005+5106. This artist’s illustration depicts what a team of astronomers think…
Magnetic fields are produced by a dynamo mechanism inside stars and emerge through the surface to the outer atmosphere, where they generate stellar magnetic storms,…

How common is our Solar System? Less common than we might think. A significant fraction of planetary systems around Sun-like stars have had a very…
The supernova remnant G344.7-0.1 is across the Milky WayThe Milky Way is the galaxy that contains the Earth, and is named for its appearance from…
The first 3D-printed stellar nurseries are highly polished spheres about the size of a baseball, in which swirling clumps and filaments represent star-forming clouds of…
Astronomers have discovered a giant, spherical cavity within the Milky Way galaxy; its location is depicted on the right. A zoomed in view of the…
Core-scale magnetic fields (red segments) inferred using high-resolution and sensitive dust emission polarization observations using JCMT. The Solar-type star forming cores fragmented out of B213…
A quarter of Sun-like stars eat their own planets, according to new research. How rare is our Solar System? In the 30 years or so…
An image of the magnetized, star-forming core BHR 71 IRS1. The outermost low-density gas is shown by the blue and white background colors; the centrally…
To investigate the physics underpinning white dwarf evolution, astronomers compared cooling white dwarfs in two massive collections of stars: the globular clusters M3 and M13.…
