Comet 2I/Borisov is only the second interstellar object known to have passed through the solar system. This mysterious visitor from the depths of space is the first identified comet to arrive here from another star.
Since its 2018 launch, NASA's Parker Solar Probe (record-holder for closest-ever spacecraft to the Sun) has finished three of 24 planned passes through never-before-explored parts of the Sun's atmosphere.
Astronomers have measured a 40 billion solar mass black hole in the Holm 15A galaxy. Their results could lead to even more massive black holes.
The discovery of Metallosphaera sedula - the bacteria that eats meteorites not only invites speculation on how terrestrial life could survive off world, it offers insight into how early biology could have received key nutrients through space rocks.
On Thursday, a SpaceX Falcon 9 rocket lifted off from Cape Canaveral in Florida bound for the International Space Station. It marked SpaceX’s 19th trip to the space station and the company's final trip to the station for the decade.
We get excited when we detect water on another world, which so far hasn’t happened often. But this study shows that the presence of water, though tantalizing and worth pursuing scientifically, guarantees nothing.
Extensive observations indicated the presence of three supermassive back holes in the three galaxies NGC 6240 that are the process of merging. Up until now, such a concentration of supermassive black holes had never been discovered in the universe.
Researchers have observed a gamma-ray burst with an afterglow that featured the highest energy photons -- a trillion times more energetic than visible light - ever detected in a burst.
TESS is likely to find between 10,000 and 15,000 exoplanet candidates by 2025. By 2030, the European Space Agency’s GAIA and PLATO missions are expected to find another 20,000-35,000 planets.
Scientists have been gathering a growing well of evidence that our universe may be connected via a vast array of large-scale "structures" that seem to reach out across the cosmos to synchronize the movements of galaxies that are separated by vast distances.
Years of observational data, cosmological models and physics suggest the Universe is flat. However, a recent study suggests that the Universe is actually curved and closed, like an inflating sphere.
SpaceX team has completed 13 successful tests in a row of upgraded Mark 3 parachutes for Crew Dragon. Most recent test demonstrated the parachute system’s ability to land the spacecraft safely in the unlikely event that one of the four main parachutes fails.
Hygiea is located in the main asteroid belt between Mars and Jupiter and is the fourth largest object in the main asteroid belt. Now, a new telescopic survey suggests Hygiea is a dwarf planet, due to its surprisingly spherical shape.
NASA unveiled new spacesuits that astronauts will wear on the moon and Mars. The suits are designed to outperform those used during the Apollo program.
