Quasars suggest fine-structure constant differed billions of years ago at opposite ends of universe

How magnetic flux emerges into the Sun's surroundings

Observations with the Herschel infrared space observatory have revealed that ultraviolet light is a key ingredient in the formation of an unexpected cloud of water vapor around an old red giant star.

Extended run could find first evidence of the Higgs boson

NGC 4666's vigorous star formation is probably the result of gravitational interactions with neighboring galaxies.

Despite the cancellation of the Constellation program, there is still a strong chance that the booster could play a part in future launch vehicles.

New device could act as an electronic 'nose'

The data indicate that young gas-giant planets are extremely cloudy.

The non-toxic oxygen and methane propellant combination has the potential for greater engine performance.

Research indicates that the Sun's magnetic cycle, which produces differing numbers of sunspots over an approximately 11-year cycle, may vary more than previously thought.

Physicists explain scanning-tunnelling microscope mystery

A new image shows the elliptical depression with unprecedented clarity.

Studying many stars with stellar seismology could help scientists better understand how magnetic activity cycles can differ from star to star, as well as the processes behind such cycles.

Particle-physics lab insists cuts will not affect Large Hadron Collider

Model explains how these galactic monsters formed in the early universe

Systems with multiple transiting planets are particularly rich with information that provides clues as to their physical characteristics.

The Rosette Nebula is a huge star-forming region in our Milky Way Galaxy.

Scientific results show that when asteroids spin fast enough, they can undergo rotational fission, splitting into two pieces that then begin orbiting each other.

Scientists believe that planetary collisions are kicking up fresh dust.

Scientists believe there are as many as seven planets orbiting this Sun-like star.
