"To explore strange new worlds; to seek out new life and new civilizations; to boldly go where no one has gone before!"

NASA’s Hubble and Webb telescopes have revealed that tiny objects beyond Neptune may preserve the earliest history of planet formation.

Astrophotographer Kevin Boardman spent more than 16 hours capturing the intricate filaments of the Crescent Nebula.

What used to be a rare sight gracing the twilight sky is now becoming strangely commonplace. If you live on either U.S. coast, you have to good chance at seeing what’s become a common sky scene in our modern technocene era: a space launch jellyfish.

The Earth and the Moon have nearly identical isotopic compositions, and the Giant Impact Hypothesis strives to explain this. New research into the ancient impact shows how the temperature of both worlds, and how it affects the strength of the materials involved in the collision, shaped the outcome, including the isotopic compositions.

Exploring astronaut health and photographing the Moon and Earth topped the research schedule for the Expedition 75 crew aboard the International Space Station on Tuesday. The orbital residents also kept up life support maintenance following the departure of cargo spacecraft the day before.

NASA’s Hubble Space Telescope captures a photogenic nebula, N44, in the Large Magellanic Cloud in this Sept. 3, 2026, image. N44 is dominated by two features: a vast central void and a shell of dense, dusty gas. The central void is a ‘superbubble’ spanning roughly 210 by 140 light-years across. The glittering stars at the […] The post Superbubble in the Large Magellanic Cloud appeared first on NA…

Nature Astronomy, Published online: 08 September 2026; doi:10.1038/s41550-026-02914-6 BepiColombo’s flyby at just 165 km from Mercury observed sustained precipitation of energetic solar protons and electrons onto the planet’s surface, with potentially long-term impact on its weathering and mineralogy.

Physicists around the world remain deeply divided on key mysteries of the universe, from dark matter to quantum gravity. The standard cosmological model failed to gain majority support, and no leading theory dominated the survey results. The largest survey ever conducted among physicists worldwide reveals surprisingly little agreement on some of the field’s biggest mysteries, [...]

An analysis of 75 meteorite falls identified seven distinct processes that occur as space rocks melt, break apart, and slow down before reaching the ground. A space rock entering Earth’s atmosphere does far more than simply “burn up.” By examining 75 meteorite falls recorded in videos and photographs, researchers identified seven distinct stages that shape [...]

Astronomers have combined 2,884 Type Ia supernovae -- which are used to measure cosmic distances -- with cosmic microwave background and galaxy-mapping data, deepening cracks in the standard ‘cosmological constant’ model.

Scientists have discovered an enormous 10-sided wave pattern in the icy ammonia clouds over Saturn's south pole

A South Dakota-based instrument built to detect theoretical dark matter particles has sensed a particle interaction that's difficult to explain with known phenomena. But more data is needed to confirm that the strange substance—which scientists have never directly observed—is, indeed, the culprit
