Solar systems with so-called hot Jupiters don't seem to harbor Earth-sized planets, a discovery that will narrow the search for Earth-like worlds.
Just like human eyes, the Hubble Space Telescope can't observe the sun directly - so NASA scientists plan to study Venus's solar transit in June by using the moon as a mirror.
The image snapped by NASA’s Hubble Space Telescope may seem like a quiet patch of sky at first glance.
Astrophysicists at the University of Warwick have identified four white dwarfs surrounded by dust from shattered planetary bodies which once bore striking similarities to the composition of the Earth.
Astronomers have had their best look yet at a supermassive black hole in the process of shredding a star.
The European Space Agency (ESA) is shifting its focus to study Jupiter's icy moons and plans on launching a mission from Kourou, French Guiana, in 2022.
A recently snapped image of the region surrounding the Messier 78 nebula, just to the north of Orion’s Belt, shows clouds of cosmic dust threaded through the nebula like a string of pearls.
Jon Spaihts may pen scripts about humans exploring the far reaches of the galaxy, but does the Prometheus screenwriter really believe we will ever reach another star?
Astronauts signing up for long-term future missions to Mars and beyond will inevitably face a wide range of health issues, including microgravity-induced lymphocyte programmed cell death.
In a little over a month's time, sky-watchers will have what's likely to be a once-in-a-lifetime experience, seeing Venus pass across the face of the sun.
A population of old, volatile stellar black holes has been discovered, following an 'extraordinary outburst' from one located in a nearby galaxy.
Blue Origin, the spaceflight company backed by Amazon founder Jeff Bezos, has released the next little snippet of information about how its plans are progressing.
Astronomers at Vanderbilt University have managed to identify nearly 700 rogue stars that were likely ejected from the Milky Way galaxy.
Stars running out of nuclear fuel pass through the preplanetary or protoplanetary nebula stage - a short period in the cycle of stellar evolution that has nothing to do with planets.
The European Space Agency is to launch a mission to the sun that will get closer than ever before.
Lava flows coiled like snail shells have been found for the first time on Mars - and they're bigger than anything similar on Earth.
The Earth experienced many more giant asteroid strikes in the past than previously believed, new NASA research shows.
Saturn's giant moon Titan conceals a thick, smoggy atmosphere that is believed to be one of the most complex chemical environments in the solar system.
Most galaxies are either roughly spherical or take the shape of a flat disk - but new observations from NASA's Spitzer Space Telescope show that the Sombrero galaxy is both.
The theory of dark matter has taken another knock, with the discovery of a vast structure of satellite galaxies and clusters of stars surrounding our galaxy, stretching out across a million light years.
