Tiny galaxies prove dark matter is real, defying modified gravity theories
A new international study has provided one of the clearest signs yet that dark matter—not a change in gravity—is responsible for the mysterious way...
Ancient dead star still feasting on the remains of its planets
In about 5 billion years, our Sun will run out of hydrogen fuel and collapse into a dense, Earth-sized remnant called a white dwarf.
Though...
Most giant stars in the early universe were born as pairs, study finds
A new study from Tel Aviv University (TAU) has revealed that most massive stars in the early universe were likely born in pairs —...
Ripples in space reveal second-generation black holes billions of light-years away
