When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae. A supernova event is incredibly energetic and... more
Nestled within this field of bright foreground stars lies ESO 495-21, a tiny galaxy with a big heart. ESO 495-21 may be just 3000 light-years across, but that is not stopping the galaxy from... more
The Milky Way Project: Probing Star Formation with a New Yellowball Catalog presents a study of 518 infant star-forming regions known as "Yellowballs," drawn from a catalog made possible by the efforts of citizen... more
A breakthrough finding overturns assumptions about the maturation of galaxies and may represent a phase of every galaxy's life cycle that was unknown until... more

Supermassive black holes exist at the center of most galaxies, and our Milky Way is no exception. But many other galaxies have highly active black holes, meaning a... more
If astronomers want to learn about how supermassive black holes form, they have to start small--really small, astronomically speaking. In fact, a team including... more
Hundreds of thousands of volunteers have helped to overturn almost a century of galaxy classification, in a new study using data from the longstanding Galaxy Zoo project. The new investigation uses classifications of over 6000 galaxies... more

Astronomers probing the edges of the Milky Way have in recent years observed some of the most brilliant pyrotechnic displays in the galaxy: superflares. more
Astronomers using the Low-Frequency Array (LOFAR) telescope network have detected a vast ridge of radio emission connecting the merging galaxy clusters Abell 0399 and... more
A new, more accessible and much cheaper approach to surveying the topology and strength of interstellar magnetic fields—which weave through space in our galaxy and beyond, representing one of the most potent... more
Under construction on a remote ridge in the Chilean Andes, the Large Synoptic Survey Telescope (LSST) will boast the world's largest digital camera, helping researchers detect objects at the solar... more
The iconic appearance of a spiral galaxy is exemplified here in the form of the stunning NGC 2903, imaged by the NASA/ESA Hubble Space Telescope. It shows off whirling, pinwheeling arms with... more
This striking image was taken by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3), a powerful instrument installed on the telescope in 2009. WFC3 is responsible for many of Hubble's... more
An international team of researchers has found evidence of a ridge of radio emissions joining two galaxy clusters. In their paper published in the journal Science, the group... more
Astronomers have spotted a ridge of radio emissions 10 million light-years long joining two galaxy clusters that are slowly colliding with each other. more
