The new images — which were taken Wednesday from a distance of 3.7 million miles — show that Pluto and Charon are very different bodies, though they circle a common center of gravity and are separated by a mere 12,200 miles, NASA officials said.

A new image of the sun shows a cornucopia of X-ray and ultraviolet colors erupting from our nearest star. Our sun is in an active period with plenty of sunspots and flares, as it leaves the peak of a cycle that takes place every 11 years.

In a collision of cosmic proportions, a new video show two chunks of material smashed together inside a jet emanating from a monster black hole. The event was captured in a time lapse video taken by the Hubble Space Telescope over 20 years.

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.

Hubble Space Telescope imagery of galaxy ESO 381-12 (a.k.a. PGC 4287) may show the after effects of a galactic merger. Telltale 'shells' of gas and dust could be results of "shock waves through its structure much like ripples in a pond."

Pluto may only be the beginning of NASA New Horizons' exploration of the Edgeworth-Kuiper Belt.

Though the New Horizons spacecraft's Pluto flyby doesn't occur until July 14, great images from the probe are already rolling in. Here, Space.com highlights some of New Horizons' best Pluto pics from the close encounter's home stretch.

"Mission Pluto" will air on National Geographic Channel on July 14. That very morning, New Horizons will cruise within 7,800 miles (12,500 kilometers) of Pluto's surface, returning history's first up-close looks at the faraway world.

Does Pluto really have baby snowflakes and ice volcanoes? New Horizons team members weigh in.
08 July 2015, 02:24 PM ET
A new image taken by New Horizons yesterday (July 7), when the probe was less than 5 million miles (8 million kilometers) from Pluto, shows a large, heart-shaped feature on the dwarf planet's surface.

One of the most powerful cosmic explosions ever observed may have been powered by an object with a magnetic field 5,000 trillion times stronger than Earth's

NASA's Dawn spacecraft is staying in its current orbit around the dwarf planet Ceres a bit longer than originally planned while engineers try to figure out why the probe went into a precautionary "safe mode" last week.

Scientists knew Neptune's magnetic field was strange, just not this strange: Researchers reconstructed the magnetic field of the distant planet and found a field constantly in flux, tilted and bubbling out to one side.

A major new telescope proposed for launch in the 2030s would focus on the search for life on other planets and view the universe with 25 times higher resolution than the Hubble Space Telescope.

New Horizons team members submitted the names generated by the "Our Pluto" campaign to the International Astronomical Union (IAU) today (July 7), one week before the probe makes history's first flyby of the faraway dwarf planet.

They are three words that, after next week, will never be used to describe Pluto again, and they are about to witness their own expiration: "Not yet explored." The phrase appears on a 1991 29-cent U.S. stamp flying on New Horizons.

Neptune's rotational axis (28.3°) is a little more tilted than Earth's (23.5°) and, because it has no solid surface, its equatorial atmosphere spins more slowly (18 hrs.) than its magnetic field (16 hrs.).

NASA's Opportunity rover has 'run' a science marathon (and then some!) on the Red Planet, traveling over 26.2 miles.

The timing of explosive eruptions of vapor and ice on Saturn's icy moon Enceladus could provide new insights into the satellite's interior structure, which could be a home to life.

With less than nine days to go in its nine-year journey, NASA's New Horizons probe is set to take the first-ever up-close images of the dwarf planet Pluto. And as those images are received on Earth, they are set to air on the Science Channel.

Mars may appear to be dry and desolate, but the Red Planet can be surprisingly humid — perhaps humid enough to support life, some scientists say.
