Failed supernovae result in massive stars disappearing into the night sky without a trace. Although many stars may meet this fat, we’re just beginning to look for them!
Type Ia supernovae might be arise from single- or double-degenerate progenitor binaries. Today’s papers suggests that single-degenerate progenitors might account for the extremely bright type Ia supernovae.
The James Webb Telescope and LIGO may team up to study some of the most energetic events in our universe.
It sounds convoluted: today’s astrobite observed a lunar eclipse in order to learn about the Earth’s atmosphere, to understand more about how to observe exoplanets. How and why do they do this? Read on…
Orbiting our galaxy are many smaller dwarf galaxies. As they orbit, some of these galaxies produce vast streams of gas that stretch around our Milky Way galaxy. Much of this gas still has the potential for forming stars. This astrobite will summarize a recent discovery of one of these stars.
The massive star Eta Carinae has been observed in the infrared for over forty years. Between 1976 and 1998, astronomers saw a linear increase in the star’s brightness. But Eta Carinae has been steadily heating up ever since a close approach with its companion star in 1998, and astronomers want to know why.
