A hunt for hypothetical axions streaming from Betelgeuse turns up empty but helps physicists set constraints on their properties.
For years, astronomers thought that the objects responsible for short gamma-ray bursts get kicked out of their home galaxies shortly after they're born. But new observations prove otherwise.
When a white dwarf star explodes as a supernova, it may be detonating like a nuclear weapon on Earth, a new study finds.
A new astronomy paper theorizes that three brown dwarfs may be reaching a cosmic speed limit, beyond which they would break apart.
Scientists have uncovered more details about perhaps the most famous repeating fast radio burst, a mysterious phenomenon astronomers cannot yet explain.
Galaxies are glittering cities, massive metropolises full of stars, dust, gas, black holes, magnetic fields, cosmic rays, dark matter and more.
Astrophysicists think a newly discovered region of the Milky Way could provide hints about the evolution of our galaxy and its potentially violent past.
A new set of videos from a unique astronomy-music project transformed spacecraft data into celestial sound baths.
For 20 years, Jonathon Keats has been asking us to recalibrate our assumptions about the universe and our place in it through a series of thought experiments. A new book dives deep into his work.
Like many people staying home during the coronavirus pandemic, I have recently gotten into a new hobby: bird watching.
Looking at the scientific information gleaned from lifeless worlds could help in the search for life, one astrobiologist says.
Until the early 2000s, the only known planets were located in our own neighborhood, the Solar System.
The Hyades — the closest star cluster to our sun — is being stretched by an invisible 'lump,' researchers say.
Astrophysicist Andrea Ghez has spent her scientific career peering at the center of the Milky Way, trying to see the invisible.
New, stunningly detailed images of the Large and Small Magellanic Clouds have the potential to revolutionize our understanding of the stars making up these two dwarf galaxies.
Finnish astrophotographer J-P Metsavainio spent 1,250 hours over the course of about 12 years creating a single image that reveals the magnificent beauty of the entire Milky Way galaxy.
