Keck Observatory captures rare high-resolution images of exploded star
Scientists will now be able to measure how fast the universe is truly expanding with the kind of precision not possible before. This, after an international team of astronomers led by Stockholm University, Sweden, captured four distinct images of a gravitationally lensed Type Ia supernova, named iPTF16geu.
Gravitational wave testbed repurposed as comet dust detector
In the final months of Europe’s LISA Pathfinder mission, scientists have found an unexpected use for the trailblazing testbed for a future gravitational wave observatory by tracking the tiny dings made by microscopic particles that strike the spacecraft in deep space, exploiting the impacts to learn about the population of dust grains cast off by comets and asteroids across the solar system.

If skies are clear between midnight and the first glimmer of dawn this weekend, you may get to see some celestial fireworks from the Lyrid meteor shower. While it may not be the richest of the annual shooting star displays, the Lyrids can deliver a few fireballs and a portion of these medium-speed meteors can leave glowing trains.
