Could a suitcase-sized spacecraft listen to the universe before the first stars existed?
This week on Time Across the Solar System, Tess explores ten stories about one of astronomy’s most extraordinary rules: the farther into space we look, the further back in time we see.
We meet CosmoCube, a small spacecraft designed to hide behind the Moon and listen for ancient hydrogen from the cosmic dark ages. The James Webb Space Telescope reveals a spectacular gravitational-lensing “house of mirrors”, evidence of enormous planet-shattering collisions, mysterious Little Red Dots that may contain rapidly growing black holes, and early galaxies already spreading the ingredients needed for planets and life.
Closer to home, Webb explores tiny brown dwarfs in the stellar nursery IC 348, astronauts travel rapidly to the International Space Station, ESA’s JUICE spacecraft borrows momentum from Earth on its journey to Jupiter, Mars begins a new year, and SMILE starts watching the invisible magnetic shield surrounding our planet.
Ten stories. One big idea:
In space, looking farther away often means looking further back in time.
