With more than 5,000 known exoplanets, astronomers are shifting their focus from discovering additional distant worlds to identifying which are good candidates for further study.

The discovery of massive, early galaxies could force scientists to rethink how the first galaxies formed after the Big Bang.

Since ancient times, the stars have been set to music. Modern technology now enables scientists to convert images of space into real compositions.
The James Webb Space Telescope began sending its first images back to Earth in the summer of 2022.

NASA has been gaining momentum in recent years as investment into space has ramped up in the US. In 2022, missions dealt with the farthest, closest, hottest and coldest conditions in the universe.

A year on since the historic launch of the most powerful infrared telescope in human history, we admire and explore some of the best images it delivered in 2022.
The James Webb Space Telescope is providing astronomers with images and data that reveal secrets from the earliest era of the universe.
It has been one year since the launch of the James Webb Space Telescope and six months since the first pictures were released. Astronomers are already learning unexpected things about the early universe.
Astronomers have unpacked the mystery of how one star’s death created the nebula NGC3132 – never before seen in such detail.

The James Webb space telescope is making the headlines again – this time completing its first chemical inventory of a distant, exotic world.
Astronomers have been looking for radio waves sent by a distant civilization for more than 60 years.

The technology of an advanced alien civilization is likely to produce many signs that could be detected across the vastness of space. Two astronomers explain the search for technosignatures.
We should not rule out taking a closer look at exoplanets that have a poorly oxygenated atmosphere.
Astronomers think the most likely place to find life in the galaxy is on super-Earths, like Kepler-69c, seen in this artist’s rendering.
Newly discovered super-Earths add to the list of planets around other stars that offer the best chance of finding life. An astronomer explains what makes these super-Earths such excellent candidates.

The James Webb Space Telescope just released its first-ever exoplanet image. Here’s what’s so exciting about it, and what we can stand to learn.
Space exploration is becoming a more feasible reality, prompting a need for international cooperation.
A new publication clarifies how existing legal frameworks apply to space exploration and development. The McGill Manual also highlights the catastrophic implications of conflict in space.
James Webb has peered into the distant Universe.
James Webb has spotted extremely distant galaxies formed soon after the Big Bang, but are they old or young? Or is this the wrong question to ask?
Humanity’s remarkable powers of comprehension can be aggrandising, but ultimately they demand a sense of humility.
In the excitement, it’s easy to forget the James Webb Space Telescope’s namesake has been the subject of controversy.
Why is the universe 13.8 billion years old, but 93 billion light-years across? It’s all about how light travels through the cosmos.
TRAPPIST-1e is a rocky exoplanet in the habitable zone of a star 40 light-years from Earth and may have water and clouds, as depicted in this artist’s impression.
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.
Long before the James Webb telescope brought us these deep field images, artists have been capturing notions of space.
Through direct comparison with images from Hubble, you can start to see the exquisite detail and clarity Webb provides.
