NASA's James Webb Space Telescope was placed in Johnson Space Center's historic Chamber A on June 20, 2017, to prepare for its final three months of testing in a cryogenic vacuum that mimics temperatures in space.
joint European-US study led by experts from Niels Bohr Institute (NBI) at University of Copenhagen, Denmark, reveals a rotating stellar disk à la the Milky Way in a stone-dead galaxy 10 billion light-years from Earth. This has never been shown before. The galaxy examined is an early version of elliptical-shaped galaxies.
Research deciphering the hidden magnetic messages encoded in a rare group of meteorites has helped secure nearly half a billion dollars of NASA funding for a journey to their parent asteroid -- the only known place in the solar system where scientists can examine directly what is probably a metallic core.
Using elaborate computer simulations, a team of researchers from RIKEN in Japan and the Max Planck Institute for Astrophysics (MPA) were able to explain the recently measured spatial distributions of radioactive titanium and nickel in Cassiopeia A, a roughly 340 year old gas remnant of a nearby supernova. The computer models yield strong support for the theoretical idea that such stellar death events can be initiated and powered by neutrinos escaping from the neutron star left behind at the origin of the explosion.
The plane of the solar system is warped in the belt's outer reaches, signaling the presence of an unknown Mars-to-Earth-mass planetary object far beyond Pluto, according to UA research.
By combining the power of a 'natural lens' in space with the capability of NASA's Hubble Space Telescope, astronomers made a surprising discovery -- the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang.
Radio images give new evidence that a jet of material from one young star may have triggered the gas collapse that started another young star.
A leading astrophysicist from Queen's University Belfast has warned that an asteroid strike is just a matter of time.
An international team of scientists recently discovered the role that hot electrons may play in the waves and fluctuations detected by satellites. The research team reports its findings this week in Physics of Plasmas. Their results are based on data collected by the Van Allen Probes, twin robotic spacecraft launched by NASA in 2012 to help scientists better understand these belt regions.
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have established 'Cosmowebportal', a unique data center for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
