Thousands of galaxies shine in ultraviolet light in new Hubble image

This may help reveal how the first stars ended the universe's dark ages. A new image from NASA's Hubble Space Telescope is brimming with distant...

Yoyo stars caused off-center bubbles of ionized gas, shows study

Astronomers have developed a new code to simulate the formation of a cluster of baby stars. Comparison with the well-known real case of the Orion...

Astronomers detect rare and strange radio burst

Astronomers have found only the second example of a highly active, repeating Fast Radio Burst (FRB) with a compact source of weaker but persistent...

Does a “mirror world of particles” explain the crisis in cosmology

The idea of a mirror universe is a common trope in science fiction. A world similar to ours where we might find our evil doppelganger...

What is the best radiation shielding for the surface of Mars

The planet Mars is calling to us. At least, that is the impression one gets when examining all the planned and proposed missions to the...

The early solar system was total mayhem

There’s no question that young solar systems are chaotic places. Cascading collisions defined our young Solar System as rocks, boulders, and planetesimals repeatedly collided. A new...

The stars in other galaxies are generally heavier than the Milky Way’s stars

How many of what kinds of stars live in other galaxies? It seems like a simple question, but it’s notoriously hard to pin down, because...

Scientists discover an unusual neutron star in stellar graveyard

Astronomers have discovered a new kind of neutron star in an unusual Galactic 'graveyard'. Unlike any of its stellar neighbors, the star pulses. Scientists have...

How a type of aurora on Mars is formed

Physicists led by the University of Iowa have learned how a type of aurora on Mars is formed. In a new study, the physicists studied...

Scientists find new unexpected phenomenon in quantum physics of materials

Researchers at Northeastern have discovered a new quantum phenomenon in a specific class of materials, called antiferromagnetic insulators, that could yield new ways of...
