In 2022, a pair of stars will merge and explode, becoming one of the brightest objects in the sky for a short period. The relevant peer-reviewed paper appeared on arXiv last week (https://arxiv.org/abs/1704.05502).

The nearby, giant radio galaxy M87 hosts a supermassive black hole and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets.
Astronomers, using ALMA, captured dramatic images as they explored the firework-like debris from the birth of a group of massive stars, demonstrating that star formation can be a violent and explosive process.
Astronomers have used the NASA/ESA Hubble Space Telescope to observe the remnant of a supernova explosion in the Large Magellanic Cloud. Beyond just delivering a beautiful image, Hubble may well have traced the surviving remains of the exploded star’s companion.
Observations using ESO’s Very Large Telescope have revealed stars forming within powerful outflows of material blasted out from supermassive black holes at the cores of galaxies. These are the first confirmed observations of stars forming in this kind of extreme environment.
