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.
The blue dot in this image marks the spot of an energetic pulsar -- the magnetic, spinning core of star that blew up in a supernova explosion.
Astronomers using data from NASA's Hubble Space Telescope and ground observation have found an unlikely object in an improbable place -- a monster black hole lurking inside one of the tiniest galaxies ever known.
Scientists at the University of Leicester have shed light on the origin of so-called "ultra-long Gamma Ray bursts", in results to be presented at a meeting in Russia next week.
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.
These large, gaseous exoplanets (planets outside our solar system) can make their suns wobble when they wend their way through their own solar systems to snuggle up against their suns, according to new Cornell University research published in Science, Sept. 11.
A new survey of galaxies by NASA's Spitzer Space Telescope is taking a plunge into the deep and uncharted waters of our cosmos.
This new image from the VLT Survey Telescope at ESO's Paranal Observatory in northern Chile shows a vast collection of stars, the globular cluster Messier 54.
Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.
Using NASA's Hubble Space Telescope, astronomers have discovered a companion star to a rare type of supernova.
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.
Lupus 4, a spider-shaped blob of gas and dust, blots out background stars like a dark cloud on a moonless night in this intriguing new image.
Researchers are proposing a new way to evaluate these large-scale structures by examining their impact on the motions of galaxies.
This new NASA/ESA Hubble Space Telescope image shows a variety of intriguing cosmic phenomena.
Massive stars end their life with a bang, exploding as supernovas and releasing massive amounts of energy and matter. What remains of the star is a small and extremely dense remnant: a neutron star or a black hole.
The chemical uniformity of stars in the same cluster is the result of turbulent mixing in the clouds of gas where star formation occurs, according to a study by astrophysicists at the University of California, Santa Cruz.
