The James Webb Space Telescope has 2 powerful instruments that see light the human eye can’t.
The space agency faces major competition from rising space powers such as China and India.
An astronomer breaks down 3 key components that allow researchers to make groundbreaking discoveries – and decide when results aren’t significant.
Looking at the history of ‘biosignature’ discoveries shows why they can be problematic.
The exoplanet K2-18b could harbor a massive ocean, but scientists will need to study the planet more to see if it’s really likely to host life.
This enormous disk object formed soon after the Big Bang, challenging what we know about how galaxies grow.
Scientists already knew how to study the chemical composition of the atmosphere of exoplanets. Now, they can also study details about their powerful winds.
The chances of asteroid 2024 YR4 hitting Earth are small but fluctuating.
The SPHEREx mission will image 1 billion galaxies, 100 million stars, and 10,000 asteroids – and help to answer some of the biggest scientific mysteries.
The James Webb Space Telescope is celebrating three years from its launch. Its discoveries have already changed our understanding of the early universe.
Astronomers have detected possible signs of gases released by volcanic activity.
Cosmology could be transformed by a new wave of telescopes – both on the ground and in space.
We may never know – and the universe may not even have an edge. But here’s what we do know.
Some of the earliest galaxies found with JWST are also the brightest. That’s a problem for our ideas about the universe.
The discovery can also give clues not only about Charon, but other objects out near Pluto.
Right now, it looks like cosmology is at a tipping point.
These small galaxies are either crammed with stars or they host gigantic black holes. The data astronomers have collected continues to puzzle them.
The first International Astronomical Union General Assembly was held just over 100 years ago, in Rome, Italy.
Astronomers Vicent Martínez and Bernard Jones explain the mystery of the Hubble tension, and why it matters so much for our understanding of the universe, on The Conversation Weekly podcast.
