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.…
This illustration shows a massive star that is about to explode. The explosion was triggered after its dead-star companion (a black hole or neutron star)…
Wolf-Rayet star. Credit: Hubble Legacy Archive, NASA, ESA – Processing: Judy Schmidt Nearby star-forming region yields clues to the formation of our solar system. The…
This image depicts a young star named GM Aur eating up gas and dust particles of a protoplanetary disk, which is represented by the green…
Multi-wavelength observations of the Ophiuchus star-forming region reveal interactions between clouds of star-forming gas and radionuclides produced in a nearby cluster of young stars. The…
Rice University scientists have shown that “cool” stars like the sun share dynamic surface behaviors that influence their energetic and magnetic environments. Stellar magnetic activity…
About 2,000 light-years away from Earth, there is a star catapulting toward the edge of the Milky WayThe Milky Way is the galaxy that contains…
Red giant stars near and far sweep across the sky in this illustration. Measurements from NASA’s Transiting Exoplanet Survey Satellite have identified more than 158,000…
An image of Messier 101, the Pinwheel Galaxy, made with the Hubble Space Telescope. The bright blue clumps in the spiral arms are sites of…
When the Sun evolves to become a red giant star, the Earth may be swallowed by our star’s atmosphere, and with a much more unstable…
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…
