Researchers can now analyze precious samples of lunar rock atom by atom

The left lobe of Pluto's distinctive heart is called Sputnik Planitia, covered with craterless plains of frozen nitrogen that vaporize each day.

Pluto Has a Nitrogen Heartbeat

Nitrogen on the dwarf planet’s glacial 'heart' becomes vapor each day and freezes each night

Whether you are a telescope enthusiast or just want to step outside to enjoy the night sky, these are the phenomena to look out for this year

Dust-rich outflows of evolved stars similar to the pictured Egg Nebula are plausible sources of the large presolar silicon carbide grains found in meteorites like Murchison.

Meteorite Grains Are the Oldest Known Solid Material on Earth

The oldest dust sample, perhaps 7 billion years old, predates the formation of our planet and the sun

The hypothetical dream spacecraft flies over Uranus and past its rings and moons, too.

Maat Mons, Venus' highest volcano, one of several that may still be active in present day

Active Volcanoes May Still Exist on Venus

Scientists baked volcanic minerals in a box furnace to model how quickly lava ages on the planet’s harsh surface

The Quadrantids meteor shower, though fleeting, is famous for its especially bright, colorful "fireballs"

How to Catch the Quadrantids, the First Major Meteor Shower of the 2020s

This cosmic light show will peak in the predawn hours of January 4

The star Betelgeuse, as seen by the Atacama Large Millimeter/submillimeter Array.

A Giant Star Is Dimming, Which Could Be a Sign It Is About to Explode

Most astronomers, however, say it's unlikely that the star Betelgeuse will go supernova anytime soon

NASA's Sun-Orbiting Probe Reveals New Secrets of Our Host Star

The first findings from the Parker Solar Probe change what we know about the workings of our nearest star

An amateur astronomer in India doggedly searched for the remnants of the country's Vikram lander after it crashed into the lunar south pole.

After blipping out of contact in September, India’s Vikram lander has now been found strewn across the lunar surface

Jupiter and its Great Red Spot as seen by the Hubble Telescope on June 27, 2019.

Jupiter's Great Red Spot May Not Be Dying Out Just Yet

Earlier this year, the spot appeared to be losing big chunks, but new research suggests it was gobbling up a smaller storm

The central region of our Milky Way is a bustling galactic downtown with a supermassive black hole at its hub.

A new book, 'Light From the Void,' showcases the telescope’s images of nebulas, supernovae, supermassive black holes and more

Thanks to the ubiquity of electric light, less and less of the planet falls genuinely into darkness any more.

How Cities and Lights Drive the Evolution of Life

Urbanization and the spread of artificial light are transforming all of earth's species, bringing about a host of unintended consequences
