Greenland's largest ice sheet is thawing at a much higher rate than expected, a new study has revealed, suggesting it will add six times more water to rising sea levels than previously thought.
Archival images from the Hubble Space Telescope have revealed an infant supernova photographed just hours after the star's explosion 11.5 billion years ago.
Reference The legacy of Arecibo's nearly 60 years of astronomy research is strong, even after its loss in a dramatic 2020 collapse.
In the depths of an Alpine mountain range, a researcher is searching for life that might look just like that on other planets.
Broccoli, algae and many other plants and microbes on Earth purge toxins by morphing them into gases that might be present in exoplanet atmospheres, signaling life.
By sheer chance, astronomers have spotted the stripped core of a star that was once 12 times the mass of the sun during a stage of stellar evolution that lasts the blink of a cosmic eye.
The James Webb Space Telescope's supercold camera MIRI is back in full science mode after a technical problem on its grating wheel forced scientists to halt some observations.
Scientists have sent a batch of seeds to the International Space Station to create new strains of agricultural plants resistant to climate change.
Two SETI telescopes came together for an evening in May to scan a zone where a purported alien signal emerged in 1977. They saw no sign of life, but will likely return for more searches.
A wisp of light reflecting off the moon got caught in Earth's atmosphere, making our neighbor look like a white crown in orbit.
The oldest dead star found to have a planetary system, dating back 10.7 billion years, has been discovered covered in the rubble of destroyed worlds.
Two puffs of star-making material exude mystical glows in a recently-published Hubble Space Telescope image.

Fertility treatments and a bioprinter that can manufacture knee cartilage flew to the International Space Station Monday (Nov. 7) aboard a Cygnus cargo spacecraft.
Planets and stars are almost like parents and children, a new study suggests: The smaller bodies keep the larger ones active, helping them stay young for longer.
A computer simulation of TRAPPIST-1e shows how the James Webb Space Telescope could help the search for habitable alien worlds.
The rapid decline of the British-Irish Ice Sheet thousands of years ago may hold lessons for how melting ice sheets in Greenland and Antarctica will influence sea-level rise in the future.
