Scientists discover two ancient migration events in the Andromeda Galaxy

Astronomers have uncovered two historic events in which the Andromeda Galaxy underwent major changes to its structure. The findings shed light not only on the...

Scientists find how two suns collect matter in a binary system

Most stars in the universe come in the form of pairs – binaries – or even multiple star systems. Now, the formation of such a...

This is how a “fuzzy” universe may have looked

Dark matter was likely the starting ingredient for brewing up the very first galaxies in the universe. Shortly after the Big Bang, particles of dark...

Electron switch may get us closer to quantum computers

Quantum computing has the potential to revolutionize technology, medicine, and science by providing faster and more efficient processors, sensors, and communication devices. But transferring information...

How to tie microscopic knots

Physicists at CU Boulder have gone to creative lengths to earn their scouting merit badges for knot-tying. In a study published in the journal Science,...

Scientists find galaxy floating in a tranquil sea of halo gas

Analysis of radio pulses that passed through a galactic halo reveals a surprisingly quiescent halo with very low density and weak magnetic field. Using one...

Scientists watch a black hole shredding a star

After passing too close to a supermassive black hole, the star in this artist's conception is torn apart into a thin stream of gas,...

Scientists create an innovative device to generate light from darkness

The technology could eventually aid the more than 1 billion people around the world who lack reliable access to electricity. When frost forms on the...

Scientists discover the most massive neutron star ever measured

Astronomers using the GBT have discovered the most massive neutron star to date, a rapidly spinning pulsar approximately 4,600 light-years from Earth. This record-breaking...

New study helps explain the dimming of the most mysterious star in the universe

For years, astronomers have looked up at the sky and speculated about the strange dimming behavior of Tabby's Star. First identified more than a century...
