Calcium-rich supernova examined with X-rays for first time
For the first time ever, researchers examined a calcium-rich supernova with X-ray imaging, which provided an unprecedented glimpse into the star during the last month of its life and ultimate explosion.
Spectacular ultraviolet flash may finally explain how white dwarfs explode
For just the second time ever, astrophysicists have spotted a spectacular flash of ultraviolet (UV) light accompanying a white dwarf explosion. An extremely rare type of supernova, the event is poised to offer insights into several long-standing mysteries, including what causes white dwarfs to explode, how dark energy accelerates the cosmos and how the universe creates heavy metals, such as iron.
Short Gamma Ray Burst Leaves Most-distant Optical Afterglow Ever Detected
When a Northwestern University-led team of astrophysicists detected an afterglow of a short gamma ray burst (SGRB) located 10 billion light years away, they were shocked. Afterglows, after all, are already incredibly faint and fast signals — sometimes lasting mere hours.
Astrophysicists Capture New Class of Transient Objects
Move aside, AT2018COW. There is a new astronomical transient in the universe, and it is faster, heavier and brighter at radio wavelengths than its mysterious predecessors.
The Sky is No Limit
New remote observatory compresses distances to connect Evanston and Hawaii, allowing Northwestern researchers to venture boldly into space without leaving home.
