Last year, global astronomers picked up evidence of an explosion called a luminous fast blue optical transient, or LFBOT. But the bizarre thing about this explosion was that it kept exploding.
Every lunar swirl identified to date coincides with a magnetic field over the lunar surface, which scientists think deflects solar particles. There also seems to be a connection between lunar swirls and lava tubes buried beneath them.
The chances of finding extraterrestrial life have improved slightly after NASA announced that its Hubble Space Telescope has confirmed the size of an Earth-sized exoplanet only 22 light-years from Earth.
When future astronauts explore Mars's polar regions, they will see a green glow lighting up the night sky. For the first time, a visible nightglow has been detected in the martian atmosphere by ESA's ExoMars mission.
A recent deep field image from the Webb Space Telescope features two galaxies. These galaxies are remarkable for their distance from Earth, being the second and fourth most distant galaxies ever observed.
Scientists have spotted a stunning "aurora-like" display of crackling radio waves over the surface of the sun that is strikingly similar to the Northern Lights on Earth.
The burst that originated some 2.4 billion light-years away from Earth and struck the planet on 9 October last year may have led to changes in the upper ionosphere, according to a new study.
Every 76 minutes, like clockwork, the gamma-ray flux of Sagittarius A*, the supermassive black hole in our galaxy, fluctuates, suggesting an orbital motion of something whirling madly around the black hole.
Instruments on NASA's Webb telescope are providing new clues about the time window when planets can form around a young star.
Researchers have made the first direct detection of atomic oxygen in the atmosphere of Venus. Some say it builds the case the planet was more hospitable in the past.
Most of what we know about Enceladus and its ice-covered ocean comes from the Cassini mission. New research based on Cassini data strengthens the idea that Enceladus has the chemicals necessary for life.
Two NASA space telescopes teamed up to scrutinize a distant galaxy and discovered something mind-boggling: a gargantuan black hole inside a galaxy that’s more than 13 billion years old.
Most meteorites from Mars are just a few hundred million years old, and likely come from relatively recent volcanic events such as the eruptions on the largest volcano in the solar system, Olympus Mons.
A system of seven sweltering planets has been revealed by continued study of data from NASA's retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system.
Long ago, an alien planet crashed into Earth – causing a collision so big the debris formed the Moon and left mysterious remnants lodged deep in the Earth’s mantle.
