Galactic Evolution – Through the Lens of Oxygen?
In today’s paper, the authors describe and attempt a method to trace the evolution of our galaxy by comparing the ratio of oxygen isotopes in different regions of the Milky Way!
Hiding in the Core: could Intermediate-Mass Black Holes exist in the Galactic Center?
There’s a cluster of stars near the Milky Way’s center whose distribution and age puzzles scientists. Could an intermediate-mass black hole be the light that reveals the mystery?
Meet the AAS Keynote Speakers: Dr. Anthony Brown
For the past decade, ESA’s Gaia mission has helped reshape astronomy in more ways than you can probably think of. You can hear more about Gaia in Prof. Anthony Brown’s plenary talk at #AAS241!
Six tiny galaxies discovered right on our doorstep
Some of the smallest galaxies we know of live right next door to the Milky Way — but we’ve only just found them!
INTEGRAL: an integral key to high energy astronomy
INTEGRAL changed our understanding of X-ray binaries, and taught us so much about our galactic home. Here’s a brief look, in awe and gratitude.
Three roads diverge in a galaxy’s future, and the chosen one is almost entirely random!
Today’s paper uses simulations to understand how the Milky Way’s stellar halo formed, and also asks: what determines the evolutionary pathway taken by a galaxy over cosmic time?
