NASA's James Webb Space Telescope has officially reached its destination about 1 million miles from Earth, bringing it closer to science operations later this year.
Why it matters: The $10 billion space telescope is designed to change the way scientists understand how the universe formed not long after the Big Bang.
Nuclear physicists trying to piece together how atoms are built are about to get a powerful new tool.
Why it matters: When the Facility for Rare Isotope Beams begins experiments later this spring, physicists from around the world will use the particle accelerator to better understand the inner workings of atoms that make up all the matter that can be seen in the universe.
