After the Dinosaur-Killing Impact, Soot Played a Remarkable Role in Extinction

The famous impact 66 million years ago kicked up soot into the atmosphere that played an even bigger role in blocking sunlight than experts had realized

An ultraviolet image of the Andromeda galaxy, the closest major galaxy to the Milky Way, taken by NASA's Galaxy Evolution Explorer space telescope. Like our own galaxy, Andromeda is a spiral galaxy with a flat rotating disk of stars and gas and a concentrated bulge of stars at the center.

Streams of Stars Snaking Through the Galaxy Could Help Shine a Light on Dark Matter

When the Milky Way consumes another galaxy, tendrils of stellar streams survive the merger, containing clues about the universe's mysterious unseen matter

The artist's concept depicts a comet-like tail of a possible disintegrating super Mercury-size planet candidate as it transits its parent star named KIC 12557548. At an orbital distance of only twice the diameter of its star, the surface temperature of the potential planet is estimated to be a sweltering 3,300 degrees Fahrenheit.

Disintegrating Planets Could Be the Key to Discovering What Worlds Are Made Of

Exoplanets that have been ripped apart by their host stars could provide an opportunity to measure the minerals of the galaxy

How Jupiter May Have Gifted Early Earth With Water

A new model of the solar system suggest we have gas giants to thank for our watery world

Behind Saturn's icy rings is the moon Tethys, illuminated by the planet's reflected sunlight.

How Scientists Engineered Cassini’s Final Demise

After a rich scientific life, Cassini went out in a blaze, becoming one with the planet it had revolved around for so long

On Earth, creatures from sharks to snails to these coral polyps light up the darkness. Are glowing aliens really that far-fetched?

The Case for Going to Venus

Sending a probe to Earth’s lifeless twin could help us understand how life rises—and falls—on faraway planets

New Moon-Formation Theory Also Raises Questions About Early Earth

A new model of the impact that created the moon might upend theories about earth, too

This artist's conception shows a dim red dwarf surrounded by three planets. To hold life at their surface, red dwarf planets must orbit close to their star, putting them in the line of fire from dangerous flares.

Why the Universe Is Becoming More Habitable

The universe is far more welcoming to life today than it was when microbes on Earth arose—and will only grow more so

An artist's concept of a moon-sized body slamming into a Mercury-sized world in another solar system. High speed collisions like this were more likely to occur in systems with gas giants, but they took place early in a planet's life, allowing time for the world to recover. (NASA/JPL-Caltech)

How a Young Jupiter Acted as Both Protector and Destroyer

Like a boisterous older sibling, the gas giant both beat up and protected young Earth

An artists' conception of a dust storm on Mars. New research may explain why the truly massive dust storms seem to occur irregularly on the Red Planet.

Mars Weather Forecast Calls for Massive Dust Storms -- Here's Why

Planetary-wide dust storms on Mars, lasting for months, may be linked to the motion of the Red Planet around the solar system.

The Orion spacecraft could one day take astronauts to Mars.

Radiation Remains a Problem for Any Mission to Mars

Engineers have yet to find ways to protect astronauts from cosmic rays and solar radiation

Avalanches may have triggered the jets of material spewing from Comet Hartley 2.

Avalanches on Comets May Help Make the Icy Bodies Visible

Tumbling rocks may have lit up Comet Hartley 2, allowing its discovery in 1986

Pluto’s ‘heart’ is a giant crater that may be slowly moving across the dwarf planet’s surface, scientists say.
