Another piece of evidence suggests that this visitor formed in the bitterly cold outer reaches of a distant planetary system.

NASA’s Nancy Grace Roman Space Telescope has begun its journey into space, starting a mission that will survey the Universe on an unprecedented scale in search of clues to dark energy, dark matter and worlds beyond our Solar System.

Today’s impact of a spent Falcon 9 rocket stage on the Moon may sound dramatic, but it is neither the first human-made object to strike our natural satellite nor the largest.

One of the biggest mysteries in modern astronomy is how the Universe managed to grow enormous black holes so quickly.

A powerful wind in the early Universe may explain why some massive galaxies lived fast and died young by stopping forming stars far sooner than expected.

New orbital mapping suggests Rosalind Franklin’s Oxia Planum landing site is part of a clay-rich region hundreds of kilometres wide, raising the possibility that it records a much larger watery episode in Mars’s early history.

The Moon may preserve a record of the raw ingredients that helped life begin on Earth. New analysis of lunar samples returned by China’s Chang’e missions has revealed a diverse suite of organic compounds embedded within the soil.

Astronomers may not need to see the same dark matter signal everywhere in the Universe to confirm its existence. A new theoretical study suggests that dark matter could consist of more than one type of particle, potentially resolving a long-standing observational puzzle.
