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.

Astronomers have made the most precise measurements of the expansion rate of the universe since it was first calculated nearly a century ago. Intriguingly, the results are forcing astronomers to consider that they may be seeing evidence of something unexpected at work in the universe.
