Astronomers using data from NASA’s James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Jupiters moon Europa.
Expedition 69 crew members on the ISS marked a busy week with cleaning, maintenance, and experiments. Frank Rubio, Sergey Prokopyev, and Dmitri Petelin celebrated a year in space, while others contributed to diverse tasks and scientific investigations.
Of all the objects in the Solar System, perhaps the most spectacular are the great comets that occasionally grace our skies. If you’ve been on social media in the past few days, you’ve probably seen articles proclaiming we have such a comet in our skies right now: C/2023 P1 (Nishimura).
Planning is underway for NASA's Habitable Worlds Observatory In early August, scientists and engineers gathered in a small auditorium at Caltech to discuss how to build the first space telescope capable of detecting life on planets like Earth. The proposed mission concept, called the Habitable Worl
Queen’s researchers lead the discovery of two potential polar ring galaxies. A group of international astronomers, including researchers from Queen’s University, has identified two potential polar ring galaxies, according to results published on September 13 in the Monthly Notices of the Royal As
Scientists have discovered that cosmic structures grow slower than Einstein's Theory of General Relativity predicts, with dark energy playing a more dominant inhibitory role than previously thought. This finding may reshape our understanding of dark matter, dark energy, and fundamental cosmic theori
NASA's Small Bodies Assessment Group wants the agency to send spacecraft to visit the asteroid Apophis before it makes a close approach to Earth in 2029.
The decadal survey has highlighted such investigations as the effects of space on biology as being key to NASA's next 10 years and to the Artemis mission.
NASA's Lucy spacecraft provides its first glimpse of asteroid Dinkinesh. Over a span of two months, Lucy will get closer, testing its systems before a close flyby on November 1, 2023. The small dot moving against the background of stars is the first view from NASA’s Lucy spacecraft of the main be
A new investigation by an international team of astronomers using data from the NASA/ESA/CSA James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The discovery adds to recent studies suggesting that K2-18 b...
Astronomers have discovered the first "bubble of galaxies," an almost unimaginably huge cosmic structure thought to be a fossilized remnant from just after the Big Bang sitting in our galactic backyard.
NASA's quest for extraterrestrial life now includes technosignatures, evidence of advanced civilizations on distant exoplanets. Through AI, new research methods, and a broadened focus, scientists remain hopeful in discovering life beyond Earth. Our first confirmed proof of life beyond Earth might
A recent preprint paper examines the minimum number of people required to maintain a feasible settlement on Mars while accounting for psychological and behavioral factors, specifically in emergency situations. This study was conducted by a team of data scientists from George Mason University and holds the potential to help...
The decade-long concerns continue. NASA needs to be more transparent about the costs and schedules associated with its Space Launch System (SLS) moon rocket, a newly released audit has found.
