Astronomers have caught sight of an unusual galaxy that has illuminated new details about a celestial "sandbar" connecting two massive islands of galaxies. The research was conducted in part with NASA's Spitzer Space Telescope

The collision of two spiral galaxies has triggered this explosion, which is cloaked by dust that renders its stars nearly invisible in other wavelengths of light

After less than three weeks of heavy-ion running, the three experiments studying lead ion collisions at the Large Hadron Collider have already brought new insight into matter as it would have existed in the very first instants of the Universe's life

Some of the universe's most massive galaxies may have formed billions of years earlier than current scientific models predict, according to surprising new research led by Tufts University

By discovering the first double star where a pulsating Cepheid variable and another star pass in front of one another, an international team of astronomers has solved a decades-old mystery

Following a study of what is in effect a miniature galaxy buried inside a normal-sized one -- like a Russian doll -- astronomers using a CSIRO telescope have concluded that massive black holes are more powerful than we thought

An international team of astronomers have discovered a unique and exotic star system with a very cool methane-rich (or T-) dwarf star and a 'dying' white dwarf stellar remnant in orbit around each other

Elliptical galaxies were once thought to be aging star cities whose star-making heyday was billions of years ago

A planet with a minimum mass 1.25 times that of Jupiter [2] has been discovered orbiting a star of extragalactic origin, even though the star now finds itself within our own galaxy

Scientists have simulated, for the first time, the merger of two black holes of vastly different sizes, with one mass 100 times larger than the other. This extreme mass ratio of 100:1 breaks a barrier in the fields of numerical relativity and gravitationa
