Space telescopes are limited in size due to the difficulties and cost of getting into orbit. By revamping an old optical technology, researchers are working on a lightweight and thin telescope design.

The planet Halla looks like it should have been devoured by its host star, a red giant called Baekdu – but a secret in the star’s past may hold the answer to the planet’s present.
Stars begin to expand when they run out of fuel and can become thousands of times larger, consuming any planets in the way. For the first time, astronomers have witnessed one such event.
Astronomers are hot on the search for new exoplanets – planets that lie beyond our Solar System – which might show potential for sustaining life.
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.
Can artificial intelligence transform the search for alien intelligence?
The James Webb space telescope is making the headlines again – this time completing its first chemical inventory of a distant, exotic world.
A handful of zombie planets have been spotted – thought to have been born after the death of their host stars.
New telescope allows us to study the atmospheres of planets orbiting stars other than our Sun in unprecedented detail.
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.
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.
We may have a stolen planet in our own Solar System.
Research on exoplanets over the next couple of decades could help us more accurately estimate how many intelligent alien civilisations there are in our galaxy.
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.
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.
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.
A glimpse of a distant Jupiter-sized exoplanet sheds light on how gas giants form.
The astronomy and astrophysics decadal survey for the 2020s lays out plans to search for life on distant planets, understand the formation of galaxies and solve deep mysteries of physics.
Scientists have mapped the entire atmosphere of ultra-hot exoplanet WASP-121b.
Some planets are rejected by the Solar System that gave birth to them.
