A Unique Hypernova Revealed by a Star Rising from its Ashes
Carl Sagan once said, “we are all made of star-stuff”. Even stars are made of star-stuff: coming from an older generation of stars! A new observation has allowed astronomers to turn back the clock and study the earliest stages of this cycle.

The Solar Cycle sees our Sun alternate between phases of tempest and tranquility driven by its magnetic field roughly every 11 years. It has been difficult to measure the magnetic strength when the Sun goes silent – until now.
Peering through the lens of the Milky Way Supermassive Black Hole
One of the most important observations by the next generation of giant telescopes will be made by pointing towards the Supermassive Black Hole at the center of our galaxy.
An Exoplanet Weigh-in using Simple Dynamics
Astronomers have caught the first directly-imaged exoplanet gravitationally tugging at its host star – thereby revealing its own weight.
