Since we first spotted the TRAPPIST-1 system in February, scientists have been scrambling to learn more about these seven rocky planets circling around their red dwarf star – but research suggests the planets aren’t as hospitable as we’d hoped. Two more reports on TRAPPIST-1 again identify challenging conditions that would make it difficult for extraterrestrial

Some 5,000 light-years from Earth, there’s a bizarre and mysterious nebula that clocks an average temperature of just 1 Kelvin (−272.15 °C or −457.87 °F), making it the coldest natural object in the known Universe. For decades, scientists have struggled to explain how this otherwise unremarkable cloud of gas maintains temperatures colder than empty space

Scientists have found new evidence to support the idea that matter vanishes completely when it falls into a supermassive black hole, suggesting Einstein was right about these unquenchable voids lurking throughout the Universe. The findings show that black hole event horizons – the invisible barriers beyond which nothing can escape the intense pull of gravitational

For the first time, scientists have detected evidence of a magnetic field that’s associated with the vast intergalactic ‘bridge’ that links our two nearest galactic neighbours. Known as the Magellanic Bridge, the bridge is a huge stream of neutral gas that stretches some 75,000 light-years between our two neighbouring galaxies, the Large and Small Magellanic

Astronomers have found a giant exoplanet larger than Jupiter, but with extremely low mass – a composition that gives this mysterious ‘puffy planet’ a density very similar to styrofoam. The team who found KELT-11b, which orbits a star located about 320 light-years from Earth, says this “extraordinarily inflated” world is the third-lowest density planet with
