As our sun gets older, it's losing mass, and so its gravitational pull becomes weaker. As a result, the orbits of all the planets in our solar system are expanding.
Roughly 1300 light-years from Earth lies the Orion Nebula. A team at the Space Telescope Science Institute (STScI) in US created this zoom into the stellar nursery and a 3D visualization.
The Hubble Space Telescope was used to capture imagery of NGC 5256 (also known as Markarian 266). The interacting galaxies are 350 million light-years from Earth, in the constellation of Ursa Major.
Elon Musk just unveiled more of his grand plan for colonizing Mars. His rocket company, SpaceX, aims to land at least two cargo ships on the Red Planet in 2022 in order to place power, mining and life support systems there for future flights.
The sun is nearing a low-activity point of its solar cycle, but researchers at NASA are detecting large solar flares leaving the celestial body.
A numerical simulation of TRAPPIST-1 is used to play a piano note every time a planet passes in front of the star and a drum every time a faster inner planet overtakes its outer neighbor.
Saturn's sixth-largest moon is incredibly far from the sun, but new research shows that it could probably sustain life.
Elon Musk's space company just made history by reusing the Falcon 9 rocket.
One particular goal of JWST involves observing some of the most distant events and objects in the Universe. Another goal is understanding the formation of stars and planets. This will include direct imaging of exoplanets.
On his most recent trip the International Space Station NASA astronaut Jeff Williams used an Ultra High Definition video camera that he pointed at the planet 250 miles below.
ESO has signed an agreement with the Breakthrough Initiatives to adapt the Very Large Telescope instrumentation in Chile to conduct a search for planets in the nearby star system Alpha Centauri.
The data was collected when the spacecraft made its first orbital pass of the gas giant on Aug 27, 2016, with all spacecraft instruments turned on. The frequency range of these signals is from 7 to 140 kilohertz.
New gravity data from recent Cassini flybys of the giant planet suggest that Dione's crust floats on an ocean 62 miles below the surface, and may harbor microbial life.
The Rosetta spacecraft ended its historic mission by crashing on the surface of the dusty, icy comet. It has spent 12 years chasing in a hunt that has provided insight into the early days of the solar system and captured the public's imagination.
NASA's Hubble Space Telescope took direct ultraviolet images of the icy moon Europa transiting across the disk of Jupiter. Out of ten observations, Hubble saw what may be water vapor plumes on three of the images.
