Some want to scrap adjustment that keeps atomic time in sync with Earth
Five weeks of mapping at sea suggests two possible origins for the underwater Tamu Massif.
Astronomers observe up to three newborn planets evolving from a disk of gas and dust particles circling a distant Sun-like star.
There is a peculiar system 1,600 light-years from our solar system. It is composed of two brown dwarfs, massive objects too big to be planets and too small to fuse hydrogen and become stars. But that is not the strange part: Scientists have now discovered a Venus-sized planet around the smaller brown dwarf.

PKS 1302-102 is one of the few known quasars with a pair of black holes within its accretion disc. It is also a curious case for astronomers as it will produce a powerful explosion when these two black holes merge. The scientists trying to determine the scale of this merger estimate that it could result in an enormous release of energy.
Like a blinding beacon lighting up the night, a powerful gamma-ray-generating stellar husk has been seen pulsating in a neighboring galaxy.
Astronomers have found a rocky planet orbiting a small star that is within easy telescope views from Earth.
Astronomers capture an image of the continuing eruption of the most powerful explosion since the big bang.
Astronomers from the University of Bonn in Germany, have discovered what appears to be the longest X-ray tail associated with a stripping process from a galaxy on a large scale. This galaxy with the enormous X-ray tail is a member of a galaxy cluster known as Zwicky 8338.
One of the top engineers working on NASA's controversial EM Drive thruster at the Eagleworks Laboratory at the Johnson Space Center in Texas has spoken publicly about the current state of the project. This is the first direct update in months, as NASA is keeping a very tight lid on the developments.
Galaxies have halos surrounding them, which may be composed of both dark and regular matter. This image shows a substructure within a halo in the Q Continuum
Science fiction literature is full of stories in which tunnels in space-time known as wormholes are used for time travel. How much fact lies within the fiction? The answer is, more than you might think.
The world's fourth-largest optical telescope has a new experiment coming online.
The Eagle Nebula and the Star Queen nebula can be seen in this annotated view.
