A new study led by the University of Cambridge challenges the long-standing idea that comets helped kick-start life on our home planet, suggesting that the icy bodies were largely unable to deliver the concentrated chemical ingredients needed for prebiotic chemistry.
Trojan asteroids are mysterious space rocks that hold clues to the early solar system. Special | 3m 26sVideo has Closed Captions | CC Back in 2021, Lucy set off to explore some of the oldest and most fascinating objects in our solar system—Trojan asteroids!
Comets didn’t seed life on Earth after all, a new study suggests, potentially overturning a century-old idea. The theory that comets delivered the molecular building blocks for life on Earth is a long-standing one, since comets are known to carry…
The appearance of life on Earth is still a mystery. It's constrained by a few factors; for instance, the Earth had to have cooled before life could get started, and there had to be some liquid water, the right chemicals,…

(October 2015)What conditions are necessary for a planet to harbor life?Water, atmosphere, crust, distance from the star—as we consider changing each of these various conditions one by one, we begin to see how delicately balanced the current Earth…
A visitor from another star system has just given astronomers a surprise, and it’s hiding in plain sight, frozen inside the comet’s icy grains. The James Webb Space Telescope took a close look, and what it found doesn’t quite match…

New simulations suggest comets couldn’t have kick-started life on their own, though they may still have played a smaller role. Comets may have brought some of the ingredients for life to Earth. The problem is that they probably destroyed them…
What could a handful of dust reveal about the birth of our solar system? Scientists studying NASA's Bennu samples have found an unexpected clue buried in material billions of years old. Asteroid Bennu has been keeping a secret for 4.5 billion…
Chemistry beyond Earth and at the start of life: molecules in space, meteorites, planetary atmospheres and prebiotic chemistry.
