Life on Earth has dramatically changed the chemistry of the planet. Astronomers will measure light that bounces off distant planets to look for similar clues that they host life.
NASA released five new images from the James Webb Space Telescope, revealing incredible details of ancient galaxies, stars and the presence of water in the atmosphere of a distant planet.
It has taken eight months to test and calibrate all of the instruments and modes of the James Webb Space Telescope. A scientist on the team explains what it took to get Webb up and running.
Astronomers studying fast radio bursts recently discovered one that repeats, has a persistent radio signal and originated in a galaxy much closer than it should have.
A professor of religion and science explains different views on immortality, from the religious perspective of President Jimmy Carter to the scientific, secular take of Carl Sagan.
Sagittarius A* is a massive black hole at the center of the Milky Way. Now that astronomers have imaged it, they can begin to learn more about black holes within other galaxies across the universe.
Hypervelocity stars were discovered only 15 years ago and are the closest things in existence to real shooting stars. They travel at millions of miles per hour, so fast that they can escape from galaxies.
Most of what we know about planets outside our Solar System relates to gas-giant planets. A new study has identified and characterised a smaller exoplanet.
Studying the extreme environment of the Virgo Cluster — which comprises thousands of galaxies — helps us learn what factors can affect and start or stop star formation.
Such a mission could be developed soon, allowing astrophysicists to take selfies of the solar system and use the Sun’s gravity as a lens to peer deep into space.
The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
