The two-meter skull of an enormous new ichthyosaur species, Earth's first known giant creature, reveals how both the extinct marine reptiles and modern whales became giants.

A new study has provided the most detailed timeline of mammal evolution to date.

Cosmochemists now present the most comprehensive comparison to date of the isotopic composition of Earth, Mars and pristine building material from the inner and outer Solar System.

A 72 to 66-million-year-old embryo found inside a fossilized dinosaur egg sheds new light on the link between the behavior of modern birds and dinosaurs, according to a new study.

MIT aerospace engineers are testing a concept for a hovering rover that levitates by harnessing the moon's natural charge. The design uses tiny ion beams to charge up the vehicle and the surface underneath, with little power needed. Such an ion boost could be strong enough to levitate a 2-pound vehicle on the moon and large asteroids.

A new bird-like dinosaur that used brute strength to overcome its prey has been found by palaeontologists combing through fossils found on the Isle of Wight, on the South Coast of Great Britain.

A new study supports the longstanding idea that if life exists, it might make a home in Venus' clouds. The study's authors identified a chemical pathway by which life could neutralize Venus' acidic environment, creating a self-sustaining, habitable pocket in the clouds.

A study investigated the enigma of why sauropod fossils are only found at lower latitudes, while fossils of other main dinosaur types seem ubiquitously present, with many located in the polar regions.

Scientists have unraveled a fascinating new insight into how the landscape of the dwarf-planet Pluto has formed.

Sophisticated analysis of a rock sample taken from the Moon during the Apollo 17 mission revealed new information about the complex cooling and evolutionary history of the Moon. The diffusion patterns preserved in the mineral grains were consistent with a rapid cooling history of no more than 20-million-years at high temperatures. The finding challenges previous estimates of a 100-million-year cooling duration and supports initial rapid cooling of magmas within the lunar crust.

On April 28, 2021, NASA's Parker Solar Probe reached the sun's extended solar atmosphere, known as the corona, and spent five hours there. The spacecraft is the first to enter the outer boundaries of our sun.

Last year, scientists looked on as a star called EK Draconis ejected a massive burst of energy and charged particles many times more powerful than anything recorded on Earth's sun. Such explosive events may have been common in the early years of our solar system, the researchers say.

The European Southern Observatory's Very Large Telescope (ESO's VLT) has captured an image of a planet orbiting b Centauri, a two-star system that can be seen with the naked eye. This is the hottest and most massive planet-hosting star system found to date, and the planet was spotted orbiting it at 100 times the distance Jupiter orbits the Sun. Some astronomers believed planets could not exist around stars this massive and this hot -- until now.

The dusty surface of the moon -- immortalized in images of Apollo astronauts' lunar footprints -- formed as the result of asteroid impacts and the harsh environment of space breaking down rock over millions of years. An ancient layer of this material, covered by periodic lava flows and now buried under the lunar surface, could provide new insight into the Moon's deep past, according to a team of scientists.

About 1000 days after the Mars InSight mission deployed SEIS, the first seismometer on the red planet, researchers are analyzing new seismic data and reporting on instrument responses, using these data to plan for future planetary seismographs.

Astronomers have discovered an ultrahot Jupiter with shortest orbit of any known gas giant planet.

After decades of uncertainty, researchers have confirmed the existence of lunar carbon dioxide cold traps that could potentially contain solid carbon dioxide. The discovery will likely have a major influence in shaping future lunar missions and could impact the feasibility of a sustained robot or human presence on the moon.

Near-Earth asteroid Kamo`oalewa could be a fragment of our moon.
