Scientists believe that around 100,000 years after the big bang, helium and hydrogen combined to make a molecule called helium hydride.
This explain how massive stars are born and what’s feeding our Milky Way galaxy’s supermassive black hole.
A double-star system i.e more than 300 light-years away likely had an extreme collision between two of its rocky planets. That's how our Moon formed
A galaxy are trapping material where it is close enough to be devoured by a hungry black hole.
The planetary system around Epsilon Eridani, a star located about 10 light-years away, has an architecture remarkably similar to our solar system.
Black holes in many galaxies are actively consuming material, but our Milky Way galaxy’s central black hole is relatively quiet.
The wind flowing from the center of the Cigar Galaxy is so strong it’s pulling a magnetic field — and the mass of 50 to 60 million Suns — with it.
It turns out that supernova explosions can produce a substantial amount of material from which planets like Earth can form.
