Astronomers found that quasars don't tend to reside in protoclusters; but if there is one quasar in a protocluster, there is likely a second nearby. This result raises doubts about the relation between protoclusters and quasars.
Three papers answer a question that scientists have been asking ever since Galileo first observed the famous stripes of Jupiter: Are the colorful bands just a pretty surface phenomenon, or are they a significant stratum of the planet?
Galaxies are not static islands of stars -- they are dynamic and ever-changing, constantly on the move through the darkness of the Universe. Sometimes, as seen in this spectacular Hubble image of Arp 256, galaxies can collide in a crash of cosmic proportions.
New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create this stunning image showing a web of filaments in the Orion Nebula. These features appear red-hot and fiery in this dramatic picture, but in reality are so cold that astronomers must use telescopes like ALMA to observe them.
With NASA's Juno spacecraft, scientists have gotten a good look at the top and bottom of the planet for the first time. What they found astounded them: bizarre geometric arrangements of storms, each arrayed around one cyclone over the north and south poles - unlike any storm formation seen in the universe.
A research team of multiple institutes released an unprecedentedly wide and sharp dark matter map based on the newly obtained imaging data by Hyper Suprime-Cam on the Subaru Telescope. The team located the positions and lensing signals of the dark matter halos and found indications that the number of halos could be inconsistent with what the simplest cosmological model suggests.
Astrophysicists discovered how to control the 'micolensing' effects of strongly lensed Type 1a Supernovae with supercomputers. Armed with this knowledge they believe they will be able to find 1,000 strongly lensed Type Ia supernovae in realtime from LSST data - that's 20 times more than previous expectations.
Much like detectives study fingerprints to identify the culprit, scientists used NASA's Hubble and Spitzer space telescopes to find the 'fingerprints' of water in the atmosphere of a hot, bloated, Saturn-mass exoplanet some 700 light-years away.
