Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.

An international team of astrophysicists has imaged a large number of exocomet belts around nearby stars, and the tiny pebbles within them.

Among the most fundamental questions in astronomy is: How did the first stars and galaxies form? ̽»¨Ö±²¥James Webb Space Telescope (JWST), a partnership between NASA, the European Space Agency and the Canadian Space Agency, is already providing new insights into this question.

Scientists from the ̽»¨Ö±²¥ of Cambridge, ETH Zurich, Harvard ̽»¨Ö±²¥, and the ̽»¨Ö±²¥ of Chicago have founded the Origins Federation, which will advance our understanding of the emergence and early evolution of life, and its place in the cosmos.

Researchers have been able to make some key determinations about the first galaxies to exist, in one of the first astrophysical studies of the period in the early Universe when the first stars and galaxies formed, known as the cosmic dawn.

Astrophysicists say that cosmic inflation – a point in the Universe’s infancy when space-time expanded exponentially, and what physicists really refer to when they talk about the ‘Big Bang’ – can in principle be ruled out in an assumption-free way.

For the first time, scientists using the NASA/ESA Hubble Space Telescope have found evidence of volcanic activity reforming the atmosphere on a rocky planet around a distant star. ̽»¨Ö±²¥planet, GJ 1132 b, has a similar density, size, and age to Earth.

Researchers will use cutting-edge quantum technologies to transform our understanding of the universe and answer key questions such as the nature of dark matter and black holes.

Five researchers at the ̽»¨Ö±²¥ of Cambridge have won consolidator grants from the European Research Council (ERC), Europe’s premiere funding organisation for frontier research.

Researchers have used a combination of AI and quantum mechanics to reveal how hydrogen gradually turns into a metal in giant planets.
