Astronomers may have found the source of a particularly hard-to-spot group of near-Earth asteroids

Using NASA's Spitzer Space Telescope, astronomers have confirmed the discovery of the nearest rocky planet outside our solar system, larger than Earth and a potential gold mine of science data.

Since 2010, the best estimate of the age of Earth's magnetic field has been 3.45 billion years. But now a researcher responsible for that finding has new data showing the magnetic field is far older.

The dark red pole on Pluto's largest moon Charon may be some of the dwarf planet's own siphoned-off atmosphere.

A team of researchers has discovered the first known system, Gaia 14aae, where one star completely eclipses the other — a type of a two-star system known as a cataclysmic variable.

Astronomers have used the ESO 3.6-meter telescope to identify a planet just like Jupiter orbiting at the same distance from a sun-like star, HIP 11915. According to current theories, the formation of Jupiter-mass planets plays an important role in sh ...

Exploding star is twice as luminous as any other reported.

A newfound giant black hole nearly as massive as 7 billion suns is dozens of times larger than astronomers expected given its host galaxy's size, researchers say. The finding may call most current models of galaxy formation into question.

Astronomers have discovered a very rare system of five connected stars.

The high-energy X-ray eyes of NASA's NuSTAR have peered into some of the most heavily buried supermassive black holes known.

When galaxies collide, bright things happen in the universe. Using the Hubble Space Telescope's infrared vision, astronomers have unveiled some of the previously hidden origins of quasars, Read more at: http://phys.org/news/2015-06-galactic-fu ...

One of science’s most crucial yet underappreciated achievements is the description of the physical universe using mathematics

Astronomers making a detailed multi-telescope study of a nearby galaxy have discovered a magnetic field coiled around the galaxy’s main spiral arm.

Using the Hubble Space Telescope’s infrared vision, astronomers have unveiled some of the previously hidden origins of quasars, the brightest objects in the universe.

Theorists argue that warped space-time prevents quantum superpositions of large-scale objects.

Mission will improve contact between orbiter and Philae lander after agency says data already received is ‘amazingly exciting’

The area of our solar system where Mercury resides may once have held as many as four rocky planets. Violent collisions could have left it as the last survivor.

NASA's Hubble Space Telescope has detected a stratosphere, one of the primary layers of Earth's atmosphere, on a massive and blazing-hot exoplanet known as WASP-33b.

Mapping our Milky Way galaxy is a mind-bending challenge, but a new view of our galactic home is helping refine that map by charting more than 400 clusters where new stars are born.

Following on from the Sentinel-1 radar satellite, Sentinel-2 is the next ESA mission dedicated to Europe’s ambitious Copernicus programme. It carries an innovative high-resolution optical imager payload providing a new perspective of our planet' ...
