This 11-hour exposure taken through a telescope shows the Jellyfish Nebula, a supernovae remnant in Gemini. The stars in the image have been removed to highlight the nebula’s other features: large billows of gas and dust.
The pristine star formed outside the Milky Way and later drifted into our galaxy.
The collision likely resembles the one that formed the Moon around 4.5 billion years ago.
Without the mass stellar migration, life may not have been able to form on Earth.
Service workers, meet the future.
Venus may be hiding a vast network of underground caves carved by ancient lava.
A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form.
