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.

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.

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.

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.

The method is based on corrections astronomers make to signals from pulsars.

M87's location, coupled with long observations over Chandra's lifetime, has made it an excellent subject for investigations of how a massive black hole impacts its environment.

Based on the size of the newly discovered cliffs, scientists estimate the distance between the Moon's center and its surface has shrunk by about 300 feet.

Scientists determine that an ancient galaxy cluster is still actively producing stars.

The team used a massive galaxy cluster as a cosmic magnifying lens to study the nature of dark energy and improve current measurements of the mass and energy content of the universe.

This is the first time scientists have detected X-ray eclipses from a fast pulsar that is also accreting gas.

Scientists have demonstrated that a magnetar formed from a star with at least 40 times the mass of the Sun, but theory states that mass should form a black hole.

In addition to detailing the never-before-seen regions at the solar system's edge, IBEX data has been used in discoveries closer to Earth.
