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

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 could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.

The Apollo 17 lunar lander base is creating small-scale moonquakes on a daily basis.

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

Was Our Universe Formed Inside the Quantum Chaos of Another Universe’s Black Hole? A cosmologist explains the mind-bending hypothesis that our universe could have branched off from a black hole singularity in another universe.

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.

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 researchers better understand the appropriate conditions …

Astronomers uncover details of a massive star, ASASSN-14li, devoured by a black hole, challenging previous theories and hinting at new methods for cosmic exploration.

When NASA crashed its DART spacecraft into the asteroid Dimorphos, the goal was to shorten the space rock's orbit around its parent asteroid. The mission succeeded - but Dimorphos' orbit has continued to shrink and it isn't clear why

The galaxy 9io9 is seen as it was when the cosmos was just 2.5 billion years old, making this the earliest galactic magnetic field ever observed.

ISS inhabitants sleep strapped to the wall and experience 16 sunrises a day.

'Twisty' new theory of gravity says information can escape black holes after all: Einstein's theory of relativity say black holes are 'bald', but a new tweak to his research may give the mysterious objects their long-sought 'hair.'
