The two planets in NN Serpentis are not currently close to the binary stars, but the double-star system was not always as tight as it is now .

The binary system was uncovered when an instrument on the International Space Station caught it in the act of erupting with a massive blast of X-rays.

Researchers found water not only where it was supposed to be, but also where it's not.

Research will improve astronomers' understanding of how massive stars evolve and interact with their host environment.

The funds will be split among three universities to support their respective roles in the Hobby-Eberly Telescope Dark Energy Experiment.

Scientists decided in advance which observations they wanted to make while the spacecraft was cruising past all of Saturn's moons.

The European Southern Observatory's Very Large Telescope confirmed that a galaxy spotted earlier using Hubble is the most remote object identified so far in the universe.

Scientists found that an exoplanet's hot spot is over to the side of the planet instead of directly under the glare of the Sun.

If life existed in martian underground systems, life-forms could have been brought up to the surface via the discharges of these deep-seated fluids.

If a star has a planet, and that planet has a moon, and both of them cross in front of their star, then scientists can measure their sizes and orbits to learn about the star.

The black hole simulations might help verify general relativity, while studying dwarf galaxies.

This new mosaic shows the galaxy in different infrared hues.

The supernova released more energy than our Sun could produce in its entire lifetime.

Huchra was perhaps best known for his leadership, with his collaborator Margaret Geller, of the CfA Redshift Survey — a pioneering effort to map the large-scale structure of the universe.

Scientists say giant galaxy clusters can be used to study how dark matter and dark energy influenced the growth of cosmic structures.

Scientists suggest that young galaxies can grow by sucking in cool streams of the hydrogen and helium gas that filled the early universe.

The observations could tell scientists where some of the dust in our solar system comes from.

Scientists are interested in dust that the New Horizons is expected to encounter in the Kuiper Belt, where they believe icy objects contain samples of ancient material.

Scientists found carbonate minerals exist along with hydrated silicate minerals of a likely hydrothermal origin.

Helium's re-ionization occurred at a transitional time in the universe's history when galaxies collided to ignite quasars.
