An international team of astronomers under the guidance of graduate student Leah Morabito of Leiden Observatory has for the first time discovered the largest carbon atoms outside our Milky Way with the LOFAR radio telescope.

Big Black Holes Can Block New Stars

Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found.

Peering through a giant cosmic magnifying glass, NASA's Hubble Space Telescope has spotted a tiny, faint galaxy -- one of the farthest galaxies ever seen. The diminutive object is estimated to be more than 13 billion light-years away.

Space scientists at the University of Leicester have detected a curious signal in the X-ray sky -- one that provides a tantalizing insight into the nature of mysterious 'dark matter.'

A group of researchers led by Melina Bersten of Kavli IPMU recently presented a model that provides the first characterization of the progenitor for a hydrogen-deficient supernova.

Galaxy clusters are the largest objects in the Universe held together by gravity but their formation is not well understood.

Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar - a dense stellar remnant left over from a supernova explosion - ever recorded.

The Milky Way As Seen From Orbit

This eye-catching panorama of the night sky and the Milky Way on Sept. 27. by One of the Expedition 41 crew members aboard the International Space Station.

Certain primordial stars--those between 55,000 and 56,000 times the mass of our Sun, or solar masses--may have died unusually. In death, these objects--among the Universe's first-generation of stars--would have exploded as supernovae and burned completely, leaving no remnant black hole behind.

One of the Expedition 41 crew members aboard the Earth-orbiting International Space Station on Sept. 13, 2014 captured this image of a starry sky.

The Balloon Observation Platform for Planetary Science (BOPPS) is a high-altitude, stratospheric balloon mission that is planned for launch today to study a number of objects in our solar system, including an Oort cloud comet.

New modeling studies from Carnegie's Alan Boss demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up.

Massive galaxies in the Universe have stopped making their own stars and are instead snacking on nearby galaxies, according to research by Australian scientists.

The Alpha Magnetic Spectrometer (AMS) collaboration has today presented its latest results. These are based on the analysis of 41 billion particles detected with the space-based AMS detector aboard the International Space Station.

Galaxy mergers are quite common throughout the history of the Universe and for decades astronomers believed that these cosmic collisions led primarily to the formation massive elliptical galaxies.

A planet may be causing the star it orbits to act much older than it actually is, according to new data from NASA's Chandra X-ray Observatory. This discovery shows how a massive planet can affect the behavior of its parent star.

A new survey of galaxies by NASA's Spitzer Space Telescope is taking a plunge into the deep and uncharted waters of our cosmos.

Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.

Before iPhones and laptops there were human computers, some of whom worked at the Harvard College Observatory. Women like Henrietta Swan Leavitt, Williamina Fleming, and Annie Jump Cannon made some of the most important discoveries in astronomy in the early 20th century.

Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed "Sparky," is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate.
