How did Mars get its moons?
Astronomers calculated possible trajectories for small objects approaching Mars. They found that as many as 1 in 50 get captured in orbit,…
How do small galaxies get magnetic fields?
Astronomers showed that small galaxies orbiting larger galaxies become 2 to 8 times more magnetic after nearing their hosts.
Energetic winds from a distant X-ray source
A team of astronomers were studying GRS 1716-249, an object believed to host a black hole. A wind of gas flowing out of it can be seen in…
Using The Big Bang As A Ruler
Baryon acoustic oscillations, an artifact remaining from the Big Bang, can be used by scientists to measure cosmological distances…
Two Black Holes Made a Mega Black Hole!
1.76 billion light years away, two black holes smashed into one another, bearing one huge black hole the size of 53 suns. The explosion from…
