The radar systems of airports and military systems on Earth can be seen far across space, meaning that if there is intelligent alien life out there, within 200 light years away, they might be able to detect it.
Mars has many similarities to Earth, but its habitability appears to be limited. Now, astronomers seem to know why.
Two ambitious missions, one underway and one proposed, will help generate artificial solar eclipses from space to reveal the deepest mysteries of the Sun's corona.
New research by international astronomers reveals the remains of a star destroyed by two powerful explosions. New technology has provided unique evidence.
NASA's DART mission successfully knocked an asteroid off course, but new findings show that flying debris played a larger role in the impact than previously thought, complicating future deflection plans.
Scientists propose that Earth could be located within a gigantic empty region, a hypothesis that would resolve one of the greatest controversies in modern cosmology and rethink what we know about the universe.
Citizen scientists make a major discovery by sifting through thousands of images playing stellar spot the difference.
A new study combines recent measurements with the axion dark energy model to propose that the universe will end in a Big Crunch in 20 billion years.
Astronomers have confirmed the detection of 3I/ATLAS, an interstellar comet speeding through the solar system. It will pass between the orbits of Mars and Earth in October, offering a unique opportunity to study distant cosmic visitors.
New research suggests the existence of mysterious celestial bodies propelled by dark matter at the center of the Milky Way. If confirmed, it could be a key clue to solving one of the deepest mysteries of modern cosmology.
After conducting some exposure tests, the research indicated that human lung cells suffered more damage from atmospheric pollutant particles than from lunar dust particles.
