Researchers say they've conducted the first reconnaissance of a distant planetary system, collecting the spectra of four red exoplanets which orbit a star 128 light years away from Earth.
NASA has created a 3D reconstruction of ancient water channels below the surface of Mars, revealing evidence of a catastrophic flood in the last 500 million years.
Activities aboard the International Space Station (ISS) continue to ramp up for next week’s departure of three crew members and the arrival of three new residents at the end of the month.
Scientists at the University of York say they've dispelled the so-called firewall paradox which suggests that anything falling into a black hole would be burned up as it crossed the event horizon.
Using binary stars as a standard for reference, astronomers have measured the distance to our neighbouring galaxy, the Large Magellanic Cloud (LMC), more accurately than ever before.
The evidence is piling up that the building blocks of life could have been brought to Earth by comets, after emerging in the dust of interplanetary space.
Astronomers have found the strongest evidence yet that the ocean on Jupiter's moon Europa may consist of salty water, like our own. And, they say, that salty water appears to be making its way to the surface.
NASA's Cassini spacecraft spots the bright, cloudy terrestrial planet, Venus, as it peers over the shoulder of giant Saturn, through its rings, and across interplanetary space.
As NASA's SpaceX Dragon spacecraft docks with the ISS, its head, Charles Bolden, has warned that recent political events could impact the agency's mission.
The first NASA spacecraft designed to fly astronauts beyond Earth orbit since the Apollo era of yore is apparently well on its way to making a flight test next year.
It may look like something from "The Lord of the Rings," trilogy (think the Eye of Sauron), but this fiery swirl is actually a real-life planetary nebula known as ESO 456-67 imaged by NASA's Hubble space telescope.
SpaceX managed to successfully launch its third flight to the International Space Station (ISS) this morning despite an issue with the Dragon spacecraft's thruster pods.
