The current theoretical model for the composition of the universe is that it’s made of ‘normal matter,’ ‘dark energy’ and ‘dark matter.’ A new study challenges this.
Although more eroded and not as tall, the newly discovered volcano rivals the others in diameter. It’s about 450 km across. The volcano sits on the eastern edge of a broad rise called Tharsis, home to 3 other well-known giant volcanoes.
SpaceX's Starship rocket, designed to eventually send astronauts to the moon and beyond, completed nearly an entire test flight through space on its third try on March 14, getting farther than ever before, but disintegrated on its return to Earth.
Falling pieces of space debris could be altering the stratosphere and negatively impacting our climate, new research suggests.
Something much closer to home may be behind the seismic signals purported to be caused by an interstellar meteor falling to Earth 10 years ago.
Study reveals that deep-sea currents have been weakening, strengthening during 2.4m-year climate cycles
Using NASA’s Juno spacecraft, scientists have calculated the rate of oxygen production on Jupiter’s moon Europa — the first time any spacecraft had directly measured charged oxygen and hydrogen particles from the moon’s atmosphere.
The vast majority of exoplanets are uninhabitable. For the few that may be habitable, we can only determine if they are by examining their atmospheres. LIFE, the Large Interferometer for Exoplanets, can help.
Some 100 light-years from the Solar System dwells the most mathematically perfect planetary system we've ever seen. The star at its center – a temperate orange dwarf called HD 110067 – is orbited by six exoplanets.
A galaxy some 750 million light-years away has been discovered hosting the heftiest pair of supermassive black holes we've ever seen.
According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the early cosmic dawn were small dwarf galaxies that flared to life, clearing the fog of murky hydrogen that filled intergalactic space.
Here's a front row seat on what it would be like to return to Earth inside a space capsule.
Astronomers have found water vapor around a young star within the constellation Taurus, 450 light-years away from Earth.
A white dwarf star that devoured at least a chunk of one of its planets has been betrayed by a scar of vaporized metal marring it surface – the tell-tale remnants of the planet that once orbited the star before spiraling into its doom.
Spanish professor argues that that water or other liquid-dwelling aliens, as well as civilizations on super-Earths, may actually be trapped on their planets due to "physical limitations".
