In 2014, astronomers using the NASA/ESA Hubble Space Telescope found that this enormous galaxy cluster contains the mass of a staggering three million billion suns—so it's little wonder that it has earned the nickname of "El Gordo" ("the...Show More Summary
Astronomers have performed abundance measurements for 11 globular clusters in the galaxies NGC 147, NGC 6822, and Messier 33. The new study, presented January 9 in a paper published on arXiv.org, could improve our knowledge about chemical composition of stellar populations in the universe.
ESA's Jupiter Icy Moons Explorer – JUICE – passed an important milestone, the ground segment requirements review, with flying colours, demonstrating that the teams are on track in the preparation of the spacecraft operations needed to achieve the mission's ambitious science goals.
Astrophysicists at Goethe University Frankfurt set a new limit for the maximum mass of neutron stars: They cannot exceed 2.16 solar masses.
An Ariane 5 rocket put four GPS satellites into orbit on Tuesday for Europe's Galileo navigation project, Arianespace said.
Brazilian astronomers have performed photometric observations of the dwarf nova V2051 Oph during its quiescent period, which revealed important insights into the nature of this object. The results were presented in a paper published January 4 on the arXiv pre-print repository.
Four stars in the night sky have been formally recognised by their Australian Aboriginal names.
Colorful swirling cloud belts dominate Jupiter's southern hemisphere in this image captured by NASA's Juno spacecraft.
To have a full picture of the lives of massive stars, researchers need to study them in all stages – from when they're a mass of unformed gas and dust, to their often dynamic end-of-life explosions.
A rocket carrying a classified U.S. satellite has blasted off from California.
Virgin Galactic says the latest glide test of its space tourism rocket plane was a success, nearly reaching the speed of sound high over California.
At the University of Iowa, you can see how gravity works by playing in the sand.
An international team of scientists led by researchers from the Argelander Institute for Astronomy has mapped the mass distribution in a distant galaxy cluster (RCS2J2327). This cosmic colossus is located in the constellation Pisces at a distance of approximately 6.4 billion light years. According to current research results it consists of about 85 percent invisible dark matter.
This week, Nature published an article that could challenge the theory of stellar evolution.
Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves and other radiation across the universe.
A new NASA Earth science mission in the early stages of design may achieve a transformational advance in our understanding of the global carbon cycle by mapping concentrations of key carbon gases from a new vantage point: geostationary orbit. Show More Summary
India launched a rocket carrying dozens of satellites from India and six other countries Friday from its island space center.
Astronomers and visualization specialists from NASA's Universe of Learning program have combined visible and infrared vision of the Hubble and Spitzer space telescopes to create an unprecedented, three-dimensional, fly-through view of the picturesque Orion Nebula, a nearby star-forming region.
The mystery surrounding the fate of a secret military satellite deepened Thursday when the Pentagon refused to answer even simple questions about whether the mission to launch it had gone awry.
An intensive survey deep into the universe by NASA's Hubble and Spitzer space telescopes has yielded the proverbial needle-in-a-haystack: the farthest galaxy yet seen in an image that has been stretched and amplified by a phenomenon called gravitational lensing.
