Even after the direct measurement of their gravitational waves, there are still mysteries surrounding black holes. What happens when two black holes merge, or when stars collide with a black hole? This has now been simulated by researchers using a novel numerical method.
By targeting the most massive galaxies in our universe, astronomers have studied how their stars move. The results are surprising: while half of them spin around their short axis as expected, the other half turn around their long axis.
Capitalizing on the unparalleled sharpness and spectral range of NASA's Hubble Space Telescope, an international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies.
The theory, which was submitted for publication before Hawking's death earlier this year, is based on string theory and predicts the universe is finite and far simpler than many current theories about the big bang say.
Astronomers using NASA's Hubble Space Telescope have detected helium in the atmosphere of the exoplanet WASP-107b. This is the first time this element has been detected in the atmosphere of a planet outside the solar system. The discovery demonstrates the ability to use infrared spectra to study exoplanet extended atmospheres.
A modular space telescope, nearly 100 feet across, composed of individual units launched as ancillary payloads on space missions over a period of months and years, units that will navigate autonomously to a pre-determined point in space and self-assemble.
Newly analyzed data from the Galileo spacecraft's flybys of one of Jupiter's moons two decades ago is yielding fresh insights: the magnetic field around the moon Ganymede makes it unlike any other in the solar system.
